Do you have air-conditioning?

I know this sounds silly, but many new homeowners see that they have a cooling switch on their thermostats and assume they have air-conditioning. Check outside. Is there an air-conditioner?

Check the settings on your thermostaL If you want coding, 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 at ON for continuous blower operation on AUTO if you want the blower to function only while the unit is operating.

Is your furnace plugged in or is the power switch turned on? The air-conditioner needs the fumace to circulate the air.

Is the air-conditioning disconnect or breaker turned on? If you know how to check the fuses, see if there are any blown. If you do not !mow how to check the fuses, Call a technician.

Is the furnace filter clean?

Are the air registers open?

Is the condensing unit running? (The condensing unit is the outside portion of the air-conditioner.)

Is the condenser coil clean? If not, read the instructions that came with your air-conditioner on how to clean the coil, or call a technidan. DO NOT ATTEMPT TO CLEAN THE CONDENSER WITHOUT TURNING OFF THE POWER.

Is there ice on the pipes at the evaporator coil (the indoor portion of the air-conditioner)? If there is, tum off the unit and call a technician. WARNING: DO NOT SET THE THERMOSTAT BELOW 68 DEGREES. THIS CAN CAUSE A MULTITUDE OF PROBLEMS WITH YOUR AIR-CONDITIONER, INCLUDING FREEZING UP.

Air-conditioners are designed for a 20 degree temperature differential. When it is 105 degrees outside, be happy if it is 85 degrees in your house. A temperature swing greater than this is unhealthy.

You should have your Air conditioner maintained annually by a qualified service technician. The best way to do that is with one of our Planned Service Agreements.

You should change or wash your filters on a regular schedule. We recommend at least twice a year depending on the activity in your home. More often is better, once a month would be a maximum. This is far more important in air-conditioning than in heating.

Keep the condensing unit unobstructed to allow ample air-flow around the unit (Cut down those bushes and other vegetation at least 12 inches back from the air-conditioner.
Do not build sheds or roofs over the air-conditioner.

If you have small children or pets, build an open fence around the air-conditioning unit with a gate for service accessibility.

If you have pine trees or oak trees near the air-conditioner, you may want to place something over the air-conditioner in the winter season. Do not cover the air-conditioner completely. IF YOU DO PLACE SOMETHING OVER THE AIR-CONDITIONER, MAKE SURE YOU REMOVE IT BEFORE TURNING THE AIR-CONDITIONER ON.
