Factors such as local air quality, household allergies, pets, and HVAC system requirements all play a role in selecting the right filter. Here’s what homeowners should consider when choosing an air filter that balances comfort, efficiency, and long-term performance.

Understand MERV Ratings

One of the most important factors when selecting an air filter is its MERV rating. MERV stands for Minimum Efficiency Reporting Value and measures how effectively a filter captures airborne particles. The higher the number, the smaller the particles it can trap.

MERV 1–4

 Filters with a MERV rating of 1–4 offer basic filtration and primarily capture large particles like dust and lint. These are often used to protect the HVAC system rather than improve air quality.

MERV 5–8

 MERV 5–8 filters provide better overall filtration, capturing mold spores, pet dander, and finer dust. This range is a popular choice for many households because it improves indoor air quality without restricting airflow.

MERV 9–12

 For homes with allergies or respiratory concerns, MERV 9–12 filters are a strong option. These filters help trap pollen, smoke, and other common irritants, making indoor air noticeably cleaner.

MERV 13–16

 MERV 13–16 filters offer high-efficiency filtration and can capture bacteria and some viruses. While these filters provide excellent air quality, they may not be compatible with every HVAC system. Consulting a professional before installing higher-MERV filters is important to avoid airflow issues.

Types of Air Filters

Air filters also come in a variety of materials and designs, each offering different benefits.

Fiberglass filters 

Fiberglass filters are the most affordable option and are typically disposable. They trap large particles but provide minimal protection against smaller allergens.

Pleated filters

Pleated filters have a larger surface area, allowing them to capture more particles while maintaining good airflow. These are widely used in residential homes and offer a solid balance of cost and performance.

Electrostatic filters

Electrostatic filters use static electricity to attract airborne particles. They are effective at capturing dust and allergens and are available in disposable or reusable designs.

HEPA filters 

HEPA filters are known for their ability to capture up to 99.97 percent of airborne particles. They are ideal for allergy sufferers but often require specialized HVAC systems or separate air purification units.

Washable filters 

Washable filters are reusable and environmentally friendly, but they require regular cleaning. If not maintained properly, they can lose effectiveness and impact air quality.

Choosing the Right Size

Using the correct filter size is just as important as choosing the right type. Filters that don’t fit properly allow air to bypass the filter, reducing effectiveness and allowing dust and debris into the system.

Most residential systems use one-inch filters, but some homes benefit from thicker four-inch filters that improve airflow and extend replacement intervals. Homeowners can find the correct size by checking the existing filter, HVAC system manual, or consulting an HVAC professional.

4. Replacement Frequency

Regular replacement is key to maintaining clean air and system efficiency. Standard filters typically need to be replaced every one to three months. Higher-efficiency filters may last six to twelve months, depending on usage and household conditions.

Homes with pets, allergies, or higher indoor activity levels may require more frequent changes. A clogged filter restricts airflow, forcing the HVAC system to work harder and increasing energy costs.

Why the Right Filter Matters

Choosing the right air filter isn’t just about cleaner air. It helps protect your HVAC system, improves energy efficiency, and supports a healthier home environment. Proper filtration reduces strain on your system, lowers maintenance needs, improves indoor air quality and enhances overall comfort.

The Invisible System

When most homeowners in Cedar Rapids think about home comfort, they focus on the shiny metal box sitting outside or the furnace in the basement. However, those units are only as good as the “vascular system” that carries the air. Your ductwork is the silent partner in your HVAC system; if it is poorly designed, your equipment is essentially trying to run a marathon while breathing through a straw.

A startling industry statistic suggests that nearly 93% of residential systems are improperly installed, and the ductwork is often the primary culprit. If the “lungs” of your home are restricted, even a high-efficiency furnace will never perform at the level for which you paid.

The 30% Energy Tax

Research from the National Institute of Standards and Technology (NIST) and the U.S. Department of Energy indicates that improperly installed systems can overuse energy by 30%. For many homeowners, this translates to a monthly “energy tax” caused by structural defects that prevent air from reaching its intended destination.

When ducts are leaky or undersized, the HVAC system must work harder and run longer to reach the temperature set on the thermostat. This often leads to “short-cycling,” where the system turns off before completing a full operating cycle. This rapid on-and-off movement wears out expensive components like blower motors and heat exchangers years earlier than expected.

Common Signs of Duct Distress

Understanding the red flags of poor ductwork can help you identify why your home may feel uncomfortable:

• Temperature Disparity: If one room feels like a sauna while another is a walk-in freezer, the ductwork is likely unbalanced. This happens when duct runs are too long or have too many sharp bends for air pressure to overcome.
• The Dust Cycle: Leaky return ducts can pull in dusty air from unconditioned spaces like attics or crawlspaces and blast it into your living areas.
• Audible Turbulence: Whistling, rattling, or “whooshing” noises often indicate that ducts are improperly sized for the blower motor’s capacity.
• Static Pressure: High static pressure occurs when airflow meets resistance, forcing the system to consume more energy and increasing wear and tear.

The Colony Difference: LiDAR Technology and Trueflow testing

To avoid these issues, professional installers should follow the strict standards set by the Air Conditioning Contractors of America (ACCA), for duct design. This standardized method ensures that every room receives the precise amount of airflow required for its specific load.

What is LiDAR?

LiDAR, which stands for Light Detection and Ranging, is a remote-sensing technology that uses rapid pulses of laser light to measure distances with incredible accuracy. While radar uses microwaves and sonar uses sound, LiDAR uses light, which travels faster and provides much higher resolution for mapping a 3D environment.

In a residential setting, a professional-grade LiDAR scanner (often integrated into advanced tablet software like Conduit) emits up to one million laser pulses per second. These pulses bounce off every surface in your home—walls, ceilings, windows, and existing vents—and return to a sensor that measures the exact time it took for the light to travel back.

What Does LiDAR Do for Your Ductwork?

Traditional duct design often relies on “rules of thumb” or incomplete as-built drawings that don’t account for reality. LiDAR eliminates this guesswork by creating a “Digital Twin”—a millimeter-precise, 3D replica of your home.

For your home’s air distribution system, LiDAR performs several critical functions:

• Identifies Spatial Constraints: It maps exactly how much room is available in your attic, basement, or crawlspace to route new ducts.
• Captures Existing Obstructions: It identifies where plumbing pipes, electrical conduits, or structural beams might block a necessary duct path.
• Verifies Geometry: It records ceiling heights and wall lengths automatically, ensuring that the volume of air required for each room is calculated with 100% accuracy.

The LiDAR Scan Process: Step-by-Step

1. The Scan: A technician walks through each room with a LiDAR-equipped device, capturing the exact coordinates of every surface.
2. The “Digital Twin”: The software creates a precise 3D replica of your home, recording floor-to-ceiling heights and structural details that manual measuring might miss.
3. Engineering Integration: This data is used to design a duct layout that ensures air moves through your home with the least amount of resistance.
4. Flow Optimization: By seeing a 3D model of your home’s structural obstructions (pipes, beams), we can route ducts to ensure the system doesn’t have to “fight” to move air.

Common Signs of Duct Distress

• Temperature Disparity: If some rooms feel like a sauna while others are freezing, the ductwork is likely unbalanced or leaking.
• The Dust Cycle: Leaky return ducts can pull in dusty air from unconditioned attics or crawlspaces and blast it into your living areas.
• Audible Turbulence: Whistling, hissing, or rattling noises often indicate that air is escaping through leaks or that ducts are improperly sized.

Trust Through Measurement

In the world of HVAC, a dangerous misconception persists: the idea that a larger furnace will heat your home faster and more effectively. In reality, an oversized system is a leading cause of equipment failure and high energy bills.

The U.S. Department of Energy reports that up to 93% of residential systems are oversized, often because contractors “size up” to avoid callbacks rather than performing the necessary engineering. For an Iowa homeowner, this error isn’t just a technicality—it directly impacts your wallet and your comfort during the most brutal months of the year.

Understanding the “Goldilocks Principle”

An HVAC system must be perfectly suited to its environment to operate efficiently.

• Undersized Systems: These units run endlessly without ever reaching your thermostat’s set temperature. In a Cedar Rapids winter, an undersized furnace faces a 100% duty cycle, leading to massive utility spikes and premature mechanical failure.
• Oversized Systems: These reach the set temperature too quickly and shut off—a process called “short-cycling”. This rapid on-and-off movement prevents the system from reaching its optimal operating temperature, which can cause the heat exchanger to crack over time and lead to uneven “hot and cold spots” throughout the house.
• Just Right: A system sized through a professional Manual J certified Load Calculation.  This is not a rule of thumb approach or simply assuming the original furnace size is correct.  

Why Load Calcs Matter: The Science of Heat Transfer

To find that “Just Right” size, professionals must perform a Load Calculation, a rigorous standard developed by the Air Conditioning Contractors of America (ACCA). This process models Heat Transfer—the exact measure of how much heat your home loses to the freezing Iowa air in the winter.

A proper load calculation considers specific factors unique to your property:

• The Building Envelope: The insulating R-values of your attic, walls, and floors.
• Fenestration: The orientation, size, and “U-factor” of your windows.
• Internal Heat Gains: The number of occupants and heat-producing appliances like ovens or electronics.
• Climate Data: Using “Winter Outside Design Temperatures” (the temperature that it only drops below 2.5% of the time in your specific area).

Precision Measurement with LiDAR Technology

Historically, load calculations involved manual measurements that were prone to human error. Today, contractors use LiDAR technology to measure walls, windows, and ceilings with millimetre precision. By using advanced tools and technology the folks at Colony can generate a 3D model that captures every structural detail without recording any personal information.

This 3D data tells us exactly how many BTUs (British Thermal Units) your home needs. Accurate mapping reduces guesswork, ensuring the equipment is right-sized from day one to prevent the 30% energy waste associated with improper installations.

The 10-Step Education Checklist

When an installation is performed correctly, it follows a rigorous sequence:

1. Load Calculation: Establishing the scientific heating requirements.
2. Proper Equipment Selection: Matching furnace capacity to the calculated load.
3. Duct Sizing Verification: Ensuring your existing “vascular system” can handle the air volume.
4. Airflow Checks: Measuring static pressure within the system.
5. Refrigerant & Gas Pressure Calibration: Essential for safe and efficient combustion.
6. Electrical Capacity Verification: Confirming your home can safely power the new equipment.
7. Smart Control Calibration: Ensuring your thermostat is reading room temperatures accurately.
8. System Commissioning: Testing the unit through multiple cycles to verify performance.
9. Record Keeping: Giving you the digital records of the scan and load calculation for your files.
10. Homeowner Education: Taking the time to explain how to change filters and maximize your new system’s life.

Your Partner in Home Health

Replacing a furnace is one of the most significant investments you’ll make for your home. By moving away from “rough estimates” and toward data-driven engineering, you ensure your home stays comfortable during an Iowa polar vortex without wasting a dime on unnecessary energy costs. Don’t leave it to a contractor who takes shortcuts. Trust the data, trust the technology, and trust the guys who take the time to do the math.

Many homeowners in regions like Iowa face the common challenge of hard water. While hard water may seem harmless at first glance—after all, it’s just water with minerals—it can have long-term consequences on your plumbing system and household appliances. Understanding what hard water is, its effects, and how to address it can save you time, money, and stress.

What is Hard Water?

Hard water is water that contains high concentrations of calcium and magnesium ions. These minerals dissolve naturally into water as it passes through rock formations like limestone and chalk. The level of hardness depends on the region and the mineral content in the local water supply.

In Iowa, much of the water is considered hard due to the prevalence of underground limestone deposits. While hard water isn’t harmful for drinking, its effects on plumbing and appliances are worth addressing.

How Hard Water Impacts Your Plumbing System

Scale Buildup in Pipes and Fixtures

The minerals in hard water don’t stay dissolved indefinitely. As water flows through pipes and fixtures, calcium and magnesium precipitate out, forming a chalky substance called limescale.

In Pipes: Limescale narrows the diameter of pipes, restricting water flow and reducing pressure. Over time, this buildup can lead to clogs and even pipe corrosion.

In Fixtures: Faucets, showerheads, and valves often develop visible white or greenish deposits, which can cause them to malfunction or reduce their efficiency.

Increased Wear on Water Heaters

Water heaters are particularly vulnerable to hard water because the high temperatures inside the tank accelerate mineral precipitation.

Sediment Accumulation: Minerals settle at the bottom of the water heater tank, forming a thick layer of sediment. This reduces the heater’s efficiency, as it takes more energy to heat water through the sediment layer.

Heating Element Damage: In tankless water heaters, the heating elements can become encrusted with scale, causing them to overheat and fail prematurely.

Shortened Lifespan of Appliances

Hard water affects more than just your plumbing—it also impacts water-using appliances like dishwashers, washing machines, and coffee makers.

Reduced Efficiency: Scale buildup clogs the internal components of appliances, forcing them to work harder.

Frequent Repairs: Mineral deposits can damage moving parts, seals, and connections, leading to breakdowns.

Increased Costs: Appliances may need more frequent repairs or replacements, adding to your household expenses.

Difficulty with Cleaning and Soap Usage

Hard water interferes with the performance of soaps and detergents. Calcium and magnesium react with soap, forming a sticky residue known as soap scum.

On Surfaces: Soap scum can accumulate on sinks, tubs, and tiles, requiring frequent scrubbing to remove.

On Dishes and Clothes: Dishes may appear cloudy and spotted, and clothes may feel rough or look dull after washing.

On Skin and Hair: Hard water leaves a residue on skin and hair, causing dryness and irritation.

Signs Your Home Has Hard Water

Wondering if hard water is an issue in your home? Look out for these telltale signs:

• Decreased water pressure in your faucets and shower.
• White or green crusty deposits on fixtures.
• Cloudy glassware and dishes even after washing.
• Dry skin and hair after bathing.
• Frequent issues with water-using appliances.

How to Combat the Effects of Hard Water

Install a Water Softener

A water softener is the most effective way to address hard water. These systems use a process called ion exchange to replace calcium and magnesium ions with sodium or potassium ions, preventing scale buildup.

Benefits: A water softener protects your pipes, fixtures, and appliances while improving soap effectiveness.

Types: Salt-based softeners are the most common, but salt-free alternatives are also available for those concerned about sodium levels.

Use a Water Conditioner

Water conditioners are an alternative to softeners that don’t remove minerals but instead alter their structure, preventing them from adhering to surfaces. These systems are easier to maintain and ideal for areas with moderate hardness levels.

Flush Your Water Heater Regularly

If your home has hard water, flushing your water heater every 6–12 months can remove sediment buildup and improve efficiency.

Clean Fixtures with Vinegar

For existing scale deposits, soak faucets and showerheads in a vinegar solution to dissolve limescale and restore functionality.

Invest in Specialized Products

Products like descaling agents, hard water detergents, and rinse aids can help mitigate the effects of hard water on appliances and cleaning routines.

Why Addressing Hard Water Matters

Ignoring hard water issues may seem harmless in the short term, but over time, the consequences can pile up. From costly plumbing repairs to inefficient appliances, the impact of hard water can strain both your wallet and your patience.

By taking proactive steps—like installing a water softener or performing regular maintenance—you can protect your plumbing system, extend the lifespan of your appliances, and enjoy cleaner, more efficient water usage.

Final Thoughts

Hard water is a major concern for homeowners in Marion, Tiffin and North Liberty. If you are one of the many residents actively seeking solutions to protect your plumbing and improve the water quality in your home, investing in preventative measures like water softeners and regular maintenance can help minimize its impact and keep your home’s system running efficiently. Addressing hard water proactively ensures long-term comfort and helps safeguard your home against potential issues.

Your water heater is an essential appliance in your home, providing hot water for showers, laundry, dishes, and more. However, like any appliance, it requires regular maintenance to ensure it operates efficiently and lasts as long as possible. Proper care can prevent costly repairs and unexpected breakdowns. Here are some key tips to help you maintain your water heater and extend its lifespan.

Regularly Check the Temperature Setting

One of the simplest yet most effective maintenance tasks is to check and adjust the temperature setting on your water heater. The recommended setting is typically around 120 degrees Fahrenheit (49 degrees Celsius). Keeping the temperature at this level can prevent scalding, reduce energy consumption, and minimize the risk of overheating the water heater.

Inspect the Anode Rod

The anode rod is a critical component of your water heater, designed to prevent corrosion by attracting corrosive elements in the water. Over time, the anode rod will corrode and need replacement. It’s a good idea to inspect the anode rod every few years. If it’s heavily corroded or coated with calcium, it’s time to replace it. A new anode rod can significantly extend the life of your water heater.

Flush the Tank Annually

Sediment buildup is a common issue in water heaters, especially in areas with hard water. Sediment can reduce efficiency and lead to tank corrosion. Flushing the tank annually helps remove this buildup. Here’s how you can do it:

1. Turn off the power to the water heater (electric) or set the gas control to “pilot” (gas).
2. Connect a garden hose to the drain valve at the bottom of the tank.
3. Place the other end of the hose in a safe location where hot water can drain.
4. Open the drain valve and let the water flow out until it runs clear.
5. Close the drain valve, remove the hose, and refill the tank.

Regular flushing can help maintain efficiency and prolong the life of your water heater.

Test the Pressure Relief Valve

The pressure relief valve is a safety feature that prevents excess pressure from building up inside the tank. To ensure it’s working correctly, test it annually:

1. Place a bucket under the discharge pipe connected to the valve.
2. Lift the valve’s lever to let some water flow out.
3. Release the lever and let it snap back into place.

If the valve doesn’t release water or continues to leak after the test, it may need replacement. A functional pressure relief valve is crucial for the safety of your water heater.

Insulate the Tank and Pipes

Insulating your water heater tank and pipes can improve efficiency and reduce energy costs. For the tank, use a water heater insulation blanket, making sure not to cover the thermostat or burner compartment. For the pipes, use pipe insulation to prevent heat loss as hot water travels through them. This simple step can keep your water heater operating efficiently and reduce strain on the system.

Check for Leaks and Drips

Regularly inspect your water heater for any signs of leaks or drips. Look around the base of the tank, connections, and fittings. Even small leaks can indicate a larger issue and lead to significant water damage over time. Address any leaks promptly by tightening connections or replacing faulty components.

Consider Professional Maintenance

While many maintenance tasks can be performed by homeowners, it’s a good idea to schedule professional maintenance every few years. A licensed plumber can perform a thorough inspection, flush the tank, check the anode rod, test the pressure relief valve, and ensure everything is in optimal condition. Professional maintenance can catch potential problems early and provide peace of mind.

Maintain the Area Around the Water Heater

Ensure the area around your water heater is clean and free of clutter. Proper ventilation is essential, especially for gas water heaters. Avoid storing flammable materials nearby and keep the area accessible for maintenance and emergencies.

Annual Maintenance: Your Water Heater’s Best Friend

By following these water heater maintenance tips, you can extend the lifespan of your appliance and ensure it operates efficiently. Regular maintenance not only saves you money on energy bills but also prevents unexpected breakdowns and costly repairs. Make it a habit to perform these tasks annually, and don’t hesitate to seek professional assistance when needed.

Managing humidity in your home is crucial for comfort, health, and protecting your property. Too much humidity can lead to mold growth and musty odors, while too little can cause dry skin, irritated respiratory systems, and cracked wooden furniture. Your HVAC system can help you strike the perfect balance, creating a more comfortable and healthy indoor environment.

Why Humidity Levels Matter

Before diving into maintenance tips, it’s important to understand why humidity balance is essential.

Comfort: Proper humidity levels help prevent feeling too sticky during summer or too dry in winter.

Health: Excessive humidity can encourage mold, bacteria, and dust mites, while low humidity may aggravate allergies, asthma, and dry skin.

Home Protection: High humidity can warp wood and cause peeling paint, while low humidity can crack furniture and hardwood floors.

The recommended indoor humidity level is generally between 30–50%. In Iowa, where summers can be humid and winters dry, maintaining proper humidity is especially important.

Using Your HVAC System to Maintain Humidity Levels

Install a Whole-House Humidifier or Dehumidifier

Your HVAC system can be equipped with devices to control indoor humidity effectively:

Whole-House Humidifier: Ideal for dry winter months, it adds moisture to the air as your furnace heats your home.

Whole-House Dehumidifier: Perfect for humid summers, it removes excess moisture, making your home feel cooler and more comfortable.

These systems integrate seamlessly with your HVAC, providing consistent humidity control throughout your home.

Utilize Your Thermostat

Modern thermostats often include humidity controls, allowing you to monitor and adjust levels easily. Check your thermostat settings regularly to ensure your HVAC is operating efficiently for humidity control.

Smart Thermostats: Advanced models can automatically adjust your HVAC settings based on indoor humidity readings.

Maintain Proper Airflow

Proper airflow is key to regulating humidity. Without it, excess moisture or dryness can build up in certain areas.

Keep Vents Unobstructed: Ensure that vents and registers are open and free of blockages like furniture or curtains.

Use Ceiling Fans: Fans help circulate air, promoting even humidity levels throughout your home.

Change HVAC Filters Regularly

Clogged air filters reduce airflow and make it harder for your HVAC system to regulate humidity.

• Replace filters every 1–3 months or as recommended by your manufacturer.
• Consider using high-efficiency filters to improve air quality and moisture balance.

Reduce Indoor Moisture Sources

Your lifestyle and home activities can also contribute to excess humidity.

Ventilate Properly: Use exhaust fans in kitchens and bathrooms to remove moisture during cooking and showering.

Fix Leaks: Check for plumbing leaks or roof issues that may introduce excess moisture into your home.

Dry Laundry Outdoors: Whenever possible, avoid hanging wet clothes indoors.

Seasonal Maintenance Tips

In Summer

Use Dehumidifiers: If your home feels sticky, a dehumidifier can help remove excess moisture from the air.

Service Your A/C: Ensure your air conditioner is functioning properly, as it naturally dehumidifies the air while cooling.

In Winter

Run a Humidifier: Dry air is common during Iowa winters, so a humidifier can help prevent discomfort and protect wooden furniture.

Seal Drafts: Prevent outdoor air from affecting humidity levels by sealing windows and doors.

Benefits of Maintaining Proper Humidity Levels

• Lower Energy Costs: A well-balanced humidity level can make your home feel cooler in summer and warmer in winter, reducing your reliance on heating and cooling systems.
• Improved Health: Balanced air moisture reduces respiratory issues and allergy symptoms.
• Increased HVAC Lifespan: Proper airflow and humidity prevent strain on your HVAC system, reducing wear and tear.

Final Thoughts

Your HVAC system is a powerful tool for maintaining ideal humidity levels in your home, especially in Cedar Rapids, where humidity shifts dramatically throughout the year.

Most of us have used Ultrasonic Humidifiers in our homes or offices.  We do this to help add some moisture to the inside air during the cold months when the Furnaces are constantly running. However, most of us are unaware of the negative issues they may cause. 

Ultrasonic Humidifiers can pose several issues, primarily because they may disperse tiny particles, such as minerals from tap water, into the air we breathe. This process can create a “white dust” that may irritate the lungs, particularly for individuals with respiratory issues. We receive several calls each year about Furnaces not working and one of the first questions we ask is; “Is the filter clean?”  The filter appears to be clean, however, these small “white dust” particles have covered the filter completely and restricted airflow to a point where the furnace will not operate. This is caused by the stand-alone, portable, Ultrasonic Humidifiers.

Additionally, if not properly maintained, these Humidifiers can spread bacteria and mold that may be present in the water tank. This occurs because Ultrasonic Humidifiers work by vibrating water at a high frequency to produce a fine mist.

Here are some key reasons why Ultrasonic Humidifiers may not be the best choice:

1. **Mineral Dispersal**: Tap water contains minerals that Ultrasonic Humidifiers can aerosolize, resulting in visible white dust that can settle on surfaces and be inhaled.

2. **Bacteria and Mold Growth**: If the humidifier isn’t regularly cleaned, the water tank can become a breeding ground for bacteria and mold, which can then be released into the air with the mist.

3. **Potential Respiratory Issues**: Inhaling fine particles from an ultrasonic humidifier can irritate the lungs, especially for individuals with asthma or other respiratory conditions.

To mitigate these issues, consider the following recommendations:

**Use Distilled Water**:  Always opt for distilled water in your Ultrasonic Humidifier to minimize the mineral content.

**Regular Cleaning**: Clean the humidifier tank frequently to prevent the growth of bacteria and mold.

Other Humidifier Options to Consider:

We certainly recommend a Whole House Bypass Humidifier or Steam Humidifier that is attached and integrated with your HVAC system. These deliver the exact amount of humidity to your home from a central location and are very low maintenance. With these, you do not need to worry about the “white dust.” Depending on your needs and space, a cool-mist evaporative Humidifier may be a better option for smaller applications, as it does not disperse fine particles as easily.  If you are interested in more information on Whole House Humidifiers,  please reach out to 319-364-HEAT (4328) and we will get you in touch with the correct correspondent. We also provide free estimates!

What is the reason for the refrigerant change?

First, let’s understand why this change was made mandatory. R22 has been the standard for decades, but it uses chemicals called hydrochlorofluorocarbons (HCFCs), which release chlorine when exposed to sunlight. Chlorine atoms combine with ozone to destroy the ozone layer. In 1995, the United Nations adopted the Montreal Protocol, which set out plans for the long-term phase-out of R22 and its replacement with HCFC-free R-410A. Studies have shown that R-410A contains HFCs with a high global warming potential (GWP). In 2016, the agreement was amended to the United Nations Montreal Protocol as the Kigali Amendment, setting standards but not specifying specific refrigerants to replace R-410A. It sets a January 1, 2025 deadline for the industry model to transition to non-HFC refrigerants. The organization plans to reduce HFC production by 85% over the next 15 years. It is also stated that a lower GWP model is set for 2034, which will require alternative refrigerants. Should you wait for the new R454B refrigerant, or buy a unit with R-410A that is tried and true?

Why replace with R-410A?

The main reason you should switch to R-410A equipment is because of the knowledge and understanding of it and how it reacts in a system. R-410A was first developed in 1991, entered mass production in 1995, became popular in 2005, and became the industry standard on January 1, 2013. This meant that by the time it became the primary refrigerant on the market, equipment had been produced with it for 18 years.  R454B was first developed in 2018 and will become the industry standard on January 1^st, 2026. This leaves both contractors and homeowners in limbo.

It is important to note that this change seems fast for the industry. Short-term and long-term understanding of these systems will be limited because contractors do not have the tools to learn and experiment. Training is available but limited. R454B units that have been released on January 1st, 2025 will be first-generation equipment. As with any first-generation technology or equipment, unforeseen problems may arise. We have been using R-410A equipment for nearly 20 years. Experienced technicians will pick up quickly on differences, but there will be unpredictable situations. It may be many years before we know how the new refrigerant will affect the long-term health of R454B equipment. The rapid pace of this change has left companies with little time for contractors to adequately prepare.

Is R454B safe?

There are many rumors about R454b. The first is the panic that R454B is classified as a semi-flammable refrigerant. This simply explains its ranking on the flammability spectrum. It has the same flammability as olive oil. It has been found to be non-hazardous and non-explosive. A bigger problem is that, because the refrigerant is semi-flammable, contractors must install sensors to detect its presence of a leak. This will lead to higher costs for customers, breakages and other technical issues. This sensor will also have its own control board.  R454B is expected to remain a more expensive refrigerant than R-410A. Another advantage of R454B is that new equipment requires 5-10% less refrigerant than R-410A systems and has a GWP reduction of more than 50%. However, R454B equipment is expected to be 10-25% more expensive than R-410A components.

Refrigerant Phase-Down

Although the amount of R-410A currently allowed to be produced is being gradually reduced, the date when it will no longer be allowed is not yet clear. Therefore, R-410A will continue to be available to homeowners who had or chose to purchase R-410A equipment prior to the transition.

The Phase-Out Plan is as follows:

10% reduction in 2022

Additional 30% reduction in 2024

Additional 30% reduction in 2029

Additional 10% reduction: 2034

Last 5% reduction: 2036

Phase out of R454B to begin in: 2035
