Helpful Tips Before Calling for Service

Furnace or AC not working? Here are some Helpful Tips before calling Air-Smart for Service 

When your Furnace is not heating or the AC is not cooling:

No matter what the problem with your heating & cooling system may be, we want to help.

If you’re handy and comfortable with checking a few items, then before you call us for service, try these initial troubleshooting tips.

IMPORTANT. Always – at all times – remember that there is dangerous high voltage electricity running through these units. Do not attempt to troubleshoot unless you are experienced and know how to safely work with or around high voltage. If you’re not qualified to work with or around high voltage electricity, please call Air-Smart for service. 630-871-1855

Is the unit getting power?

  • Check your fuses or circuit breakers at the electric panel to make sure fuses don’t need to be replaced or breakers re-set.
  • Remember, if your home’s power is out or disconnected, your system may not work

Is the Thermostat set correctly?

  • Make sure your thermostat has power – does it need battery replacement?
  • Check to make sure your thermostat is set on the COOL or HEAT mode and not set to OFF or FAN.
  • Double check that the thermostat is set to the right setting and temperature.

For No Heat / Insufficient Heat

  • Do you have a new or newly remodeled home? Was any work done on your gas or electricity lines recently? Check to see if your gas or electricity has been turned off during the work. If this is the case, having it turned back on may solve the problem.
  • Always check first to see if your thermostat is on, and what temperature it’s set at. If your thermostat is turned off or set incorrectly, turn on and/or reset thermostat.
  • Check your fuse box or electric panel. If you have an open circuit breaker or burned-out fuse, re-set the circuit or replace the fuse.
  • Remove any snow drifts resting against your outdoor unit.
  • Review the ‘Symptom’ categories below for help.

For No cooling / Insufficient Cooling

  • Again, always check first to see if your thermostat is on, and what temperature it’s set at. If your thermostat is turned off or set incorrectly, turn it on and/or reset thermostat.
  • Check your fuse box or electric panel. If you have an open circuit breaker or burned-out fuse, re-set the circuit or replace the fuse.

No Airflow

  • Check around your outdoor unit. If there are any leaves, hedges or property walls butting up against it, your system may have frozen up due to a dirty coil. Make sure your outdoor unit has at least one foot (12”) of clearance all around it.
  • Check the filters in each of your system components (where applicable). If any of your filters are dirty, consult your manual to clean or replace it. Or call your dealer to do this for you.
  • Check to see if there is any air coming through your vent. Your indoor blower may not be operating. If this is the case, you should contact Air-Smart. 630-871-1855

Air is Too Dry or Air is Too Moist

  • Check to make sure your humidifieris switched on. Many times it is turned off at the end of the previous heating season and forgotten to be turned back on when needed.
  • Make sure your humidifier’s summer / winter DAMPER SETTING is set in the proper position for the current season. Make sure the water valve is open. If it’s closed, consult your manual to open or unclog.
  • Check your humidifier control setting and adjust the indoor relative humidity settings to the desired comfort level for your home.
  • If it’s still not working, call Air-Smart. 630-871-1855

Noisy Air Vents

  • A high pitched sound sometimes, although not always, indicates a lack of return air. Make sure your return and supply vents are open and free of any blockages including furniture.
  • Other noises (e.g., rattling, humming, thumping or scraping sounds) could be a sign of undersized or flimsy duct work, clogged filter or wear and tear on your system’s internal components. If you hear an unusual sound, call Air-Smart. 630-871-1855
