What can I look at before scheduling a heating service call?

  1. Filter Clean? If not, change it.
  2. Check for power at unit- simple test - Put fan switch to "on" position and thermostat to "on". If Blower comes on you have high and low voltage power at the unit. If not, check:
    • Fuse box - check or replace fuse
    • Switch on furnace is set to on, if both are good, then
    • Check blower door on unit, some units have a power switch that shuts off furnace if door is off or ajar.
  3. Thermostat set to heat and set point is set ABOVE the room temperature
  4. May need to change batteries in some thermostats
  5. Is gas valve control knob set to on?
  6. If your hi efficiency furnace vents out the side wall or roof, need to:
    • Check flue or combustion air intake (if sealed combustion) for any restrictions on the exhaust or intake for snow, ice, bushes, birds nests, etc

When to replace a hot surface ignitor?

We recommend replacing a silicon carbide ignitor when the OHM reading is double that of a new ignitor, usually around 120 ohms or higher.  Silicon Nitride ignitors have a much lower OHM reading and are recommended to replace per manufacturer's specifications.

Can not see pilot light?

All the new furnaces no longer use a standing pilot light. Now they all have intermittent pilots. There are some with spark ignition, some use hot surface igniters. If yours has a pilot light, there will be a plate on the unit with instructions on how to light the pilot.

I see a red flashing light through the peep hole on the blower door?

This is generally the diagnostic LED on the control board. They will flash a code to help diagnose what is wrong with the furnace or status of furnace. For example:
  • Slow steady flash: normal, no call for heat
  • Fast steady flash: normal, call for heat
  • Four flashes - pause - four flashes, high limit open
Each control is different with different codes. Codes are sometimes listed on the boards, or on wiring diagrams on the service facts that come with the furnace.

When do I need to change my air filters?

There are many different styles of filters out there. Some are designed to last a year and some a month. Best advice is to check monthly and determine how many months between dirty filters, it will depend on the environmental factors in your home.

How often do I need to replace my humidifier pad?

This will be determined by how hard your water is. Check yearly, make sure it is not rusting or falling apart or that the lime has no build up to the point where it is restricting the air flow through the pad. If you find either condition, replace the pad. Average 1-3 years.

My main burner comes on for a few seconds and shuts off right away?

Newer furnaces have what they call a flame sensor. It detects the flame and tells the gas control its burning and to keep the gas coming. Sometimes it needs to be cleaned. Remove and clean with steel wool or clean cloth and see if that solves the problem. If you are unsure how to clean the flame sensor, please call for a service call, we can clean it and/or show you how if you would like to clean it yourself in the future.

Burners are going on and off: short cycling?

Most of the time it is the high limit turning the burners on and off. Need to check air flow proscans, for example: dirty air filter, supply air return air units shut off or blockers, v-belt slipping on blower points, etc.

My thermostat now reads the temperature in Celsius instead of Fahrenheit?

Somehow the thermostat got switched. Some stats it is as simple as pressing 2 buttons at the same time or others there is a installers setup that you have to enter to change the display. Each thermostat is different. you will need to refer to your owners manual or contact the manufacturer, many have this information on their web sites. See the links above and to the left. You will need to know the make and model of the thermostat you have either way you go.

Air Conditioning

What can I look at before scheduling a service call for cooling?

  1. Filter Clean? If not, change it.
  2. Check for power at furnace, simple test. Put fan switch to "on" position at the thermostat. If blower comes on, you have high and low voltage power at the unit. If not, check:
    • Breaker box, reset breaker, or
    • Fuse box - check or replace fuse
    • Switch on furnace, make sure it is on and fuse is good
    • Blower door on unit- Some units have a power switch that shuts the power off if door is off or ajar.
  3. Thermostat- Set to cooling and set point is set BELOW the room temperature. Not, some thermostats have a 5 minute delay built into them to prevent short cycling the compressor in the outdoor unit.
  4. Some thermostats have batteries that may need to be replaced.
  5. Is there high voltage power to control unit? Check breaker box, reset breaker, usually 2-piece breaker. Check Fuse box, check or replace fuses. Check outdoor unit disconnect by outdoor unit.

My AC runs all the time and does not keep up?

  1. Is filter clean
  2. Is the outdoor condenser coil clean, if not clean it
  3. Is unit the proper size for your home?

I see ice on one of the copper lines outside in the condenser?

This icing up is generally caused by low air flow or low refrigerant.
