Air Conditoning & Heating Repair and Service Online System Check List

If you experience trouble with your A/C or Heating system, please contact us for help and service.

 

Before you call, here are a few simple solutions you can attempt on your own. Often times you may be able to resolve your heating or A/C cooling problems on your own by following the System Check List below as well as save on unnecessary service calls.

If you are unable to fix the heating or cooling problem on your own the System Check List will serve as a guide to pinpoint the problem so we can better serve you.

 

Air Conditioning Equipment Check List

 

  • Check to make sure that your thermostat is set in the "cool" position.

  • Ensure that your outdoor air conditioning (condensing unit) is running:

  • Check the circuit breakers in the circuit breaker box (or electrical panel), most likely mounted to an outside wall in the back of the house. Are they in the "On" position?

  • Check the outdoor unit "disconnect switch" to make sure it is in the "ON" position. The disconnect switch is located near the outdoor unit. (Typically a grey 8" wide x 16" high x 4" deep box mounted to the wall).

  • Ensure that the blower motor in your furnace is running. (If the thermostat is in the "cool" position, the furnace blower should be running.)

  • If not, check to make sure the on / off switch at the furnace is in the "ON" position

  • Be sure that you have changed your filter in the furnace recently.

  • An extremely blocked filter can cause your outdoor air conditioner unit to shut down due to lack of proper airflow.

  • Your filter should be changed every month.

  • 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 Equipment

  • Check to make sure that your thermostat is set in the "heat" position

  • Make sure that the temperature setting on the thermostat is set above (or higher than) the indoor temperature showing on the thermostat.

  • This tells your heating system that it should provide heat!

  • 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 at the electrical panel to make sure they are in the "On" position.

  • Check the SSU switch (it looks like a light switch on a gray box located at the furnace) to be sure it is in the "ON" position

  • Replace the furnace filter if needed.

  • All 1-inch thick furnace filters should be replaced monthly.

  • Purolator 2-inch thick, and other high-capacity pleated filters can most likely be changed every other month or just 6 times per year.

  • If the system is running but you have not changed your filter, the filter may need to be replaced.

  • 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).
