Troubleshooting Guide

If you have any trouble with your system, remember you can always call for help and service. But here are a few simple things to try before calling the office at 943-1092 for a service visit.

  • Air Conditioning and Heat Pump Equipment (cooling)

    1. Check to make sure that your thermostat is set in the "cool" position.
    2. Ensure that your outdoor (condensing unit) is running:
    • Check the circuit breakers in the circuit breaker box (or electrical panel), most likely mounted to a wall in the garage or back of the house. Make sure they are all in the "ON" position.
    3. Ensure that the blower motor in your home is running. (If the thermostat is in the "cool" position, the blower should be running.)
    4. Be sure that you have changed your filter in the furnace recently.
    • An extremely blocked filter can cause your outdoor air conditioner unit/heat pump to shut down due to lack of proper airflow.
    • A one inch filter (poly) should be changed every month. A one inch pleated filter every two to three months. Four inch filters, Honeywell and Space Guard (Aprilaire) filters every six to twelve months as a general rule.
    5. Check all return air grilles to make sure they are not blocked by furniture.
    • Check all supply air registers to make sure they are open and blowing air. (The return air grilles are normally located on your walls and are wide and flat).
  • Gas Furnace and Heat Pump Equipment (heating)

    1. Check to make sure that your thermostat is set in the "heat" position
    2. Make sure that the temperature setting on the thermostat is set above (or higher than) the indoor temperature showing on the thermostat.
    3. Ensure that there is power to the furnace:
    • Try turning the fan to 'ON' using the fan switch on the thermostat to test for power to furnace.
    • Check the circuit breakers in the circuit breaker box (or electrical panel), most likely mounted to a wall in the garage or back of the house. Make sure they are all in the "ON" position.
    4. Has the furnace filter been replaced recently?
    • An extremely blocked filter can cause your outdoor air conditioner unit to shut down due to lack of proper airflow.
    • A one inch filter (poly) should be changed every month. A one inch pleated filter every two to three months. Four inch filters, Honeywell and Space Guard (Aprilaire) filters every six to twelve months as a general rule.
    • If the system is running but you have not changed your filter, the filter needs to be replaced.
    5. Check all return air grilles to make sure they are not blocked by furniture.
    • Check all supply air registers to make sure they are open and blowing air. (The return air grilles are normally located on your walls and are wide and flat).
