**My air conditioner does not seem to be cooling.

·       Check to see if the thermostat display is blank. If so, see the section above.

·       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.

**The display on my thermostat is blank.

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

·       If equipped, check the condensate overflow safety reservoir, located at your air handler/furnace, to make sure it has not filled up with water and raised 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.

**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 minimal or no sunlight is allowed to directly enter the room(s).

·       Check the supply-air and return-air grilles 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.

**None of the suggestions above have solved my problem.

·       Use fans to circulate air in the home and improve your comfort.

·       If there are multiple systems in your home, consider relocating activities or temporarily sleeping in the cooler area of your home.

·       Consider alternative accommodations if necessary when immediate relief is not possible.
