While JTR Heating and Air Conditioning Inc. is here to resolve all types of heating and cooling issues, anywhere in Monee and the surrounding areas, we realize you’d rather avoid a service call if possible. There are times when a very simple adjustment gets your vital equipment back to operating properly again. Before contacting us at 708-258-5166, here is a list of a few possibilities you might want to try:

For the air conditioner:
    • Is the thermostat switched over to “cooling” mode?
    • How long has it been since the air filter was cleaned or replaced?
    • Have you checked the circuit breakers (electrical panel) to make sure they are all in the “on” position?
    • Make sure the “disconnect” switch for the outdoor A/C condensing unit (usually mounted to the wall) is in the “on” position.
    • If the furnace blower motor isn’t running, verify the switch is in the “on” position.
    • Are any of the return air grilles blocked by furniture?
For the furnace:
  • Is the thermostat switched over to “heating” mode?
  • Is the thermostat adjusted to a higher setting than the indoor temperature?
  • Try turning the fan switch on the thermostat “on” to test for power.
  • Are the circuit breakers at the electrical panel all set to the “on” position?
  • The SSU switch (gray box located at the furnace) should be in the “on” position.
  • Could the air filter need to be cleaned or replaced?
  • Double check that none of the return air grilles are obstructed by furniture.
