Nothing is more frustrating than when your HVAC system stops working when you need it most, causing you to consider an emergency air conditioning and furnace repair or replacement. Not only is it stressful for you and your family to be without air conditioning or heat, but it can also be a financial burden. There are a few things you can do, however, before calling a technician.

Emergency Air Conditioning and Furnace Repair Checklist

Check your furnace’s air filter. If you have not replaced or cleaned it in a while, you may want to purchase a new one, since a dirty filter can restrict airflow through your home.
Check your circuit breakers. The breaker switch may have tripped or shut off by accident. It is important to keep in mind that a tripped HVAC breaker may indicate a more serious issue, so schedule an inspection with your local American Standard Customer Care dealer immediately.
Make sure the vents in your home are not obstructed. Blocked or closed vents can limit the airflow through your home.
Check the thermostat. If your thermostat uses a battery, it could need to be changed. You can also check to see if there is dust or dirt in the thermostat by removing the faceplate. If there is dust or dirt, use a can of compressed air to gently remove it.
Set the thermostat temperature and be patient. Frequently changing the temperature on the thermostat can cause the compressor in your system to overheat and shut down. To avoid this, be patient once you set your desired temperature; it could take up to 5 minutes for the system to turn on.

If after going through this checklist your unit is still not functioning properly it may be time to call a technician. A malfunctioning HVAC system could drive up your energy costs along with the expensive emergency furnace and air conditioning repairs, so the faster you can figure out if you need a technician the better. Our American Standard Customer Care dealers can come to your home to assess the situation and make suggests for, and complete, a repair.
