It never fails that we experience heating and air conditioning problems at the worst possible time. It is always one of the hottest days of the summer, a time when we are expecting visitors or we have just had a tough day at work and were looking forward to relaxing at home. Sound familiar? If only we could do something that would get us some relief quickly and with minimal expense. Maybe some of these suggestions will help you on that bad day when you realize your air conditioner is not cooling your home.

The Display on My Thermostat Is Blank.

Check to make sure the batteries in the thermostat are fresh.

If so equipped, check the condensate overflow safety reservoir, located at your air handler/furnace, to make sure it has not filled up with water raising the safety switch. Suction out the water and re-install the switch. Do not attempt to run the air conditioner without the switch installed properly or water damage may result.

Check the breakers for your air conditioning system. There will be one for the indoor air handler/furnace unit and another for the outdoor condensing unit. If one of them has tripped it can be reset by first moving it to the OFF position and then back to the ON position.

My Air Conditioner Does Not Seem To Be Cooling.

Check to see if the thermostat display is blank. If so, see the section "The Display on My Thermostat is Blank" in your thermostat manual.

Check the settings on your thermostat. If you want cooling, make sure the temperature control selector is set below room temperature and the system switch is on the COOL or AUTO position. The FAN switch should be set to AUTO.

Check the air filter(s) for your air conditioner and replace if necessary.

Check the bottom of the air handler/furnace to see if it is very cold and sweating. If so turn the air conditioner off for at least 4-5 hours and replace the filter. The unit is frozen and will need to defrost.

Check the breakers for your air conditioning system. There will be one for the indoor air handler/furnace unit and another for the outdoor condensing unit. If one of them has tripped it can be reset by first moving it to the OFF position and then back to the ON position.

One Room or Area of My Home Is Warmer Than the Others.

Check the air filter(s) for your air conditioner and replace if necessary.

If your home has a zone comfort system, check the settings on the thermostat for that particular zone. If you want cooling, make sure the temperature control selector is set below room temperature and the system switch is on the COOL or AUTO position. The fan switch should be set to AUTO.

Are window treatments installed? If not, install window treatments. If so, adjust the treatments so that minimal or no sunlight is allowed to directly enter the room(s).

Check the supply-air and return-air grills in the room(s) to ensure they are open completely and blowing air while the system is running.

Check if there are many electronic devices operating in the room(s). Rooms converted to offices may be warmer due to these devices and not due to the air conditioner operation.
