Help assure that your Air-conditioning is keeping you as cool as possible and working and cooling as efficiently as possible, saving you money. The following should help you decide if you need a professional to service your Air-conditioning unit.
(1) Air filter(s) MUST be clean. They should be located near the return air duct adjacent to the air handler or in a return air grill(s). Check your air filter every 30 to 90 days to make sure it is clean. Depending of the house, i.e. if you have animals you may need to clean the air filter more often. (Go clean them now!)
(2) Flip the switch on the thermostat for the fan setting to FAN ON, not AUTO. This will run the indoor fan nonstop. The outside A/C unit will still cycle with a call for cooling from the thermostat. The constant air moving will keep you cooler. You can probably keep the thermostat a degree or two higher then normal and still feel comfortable. You will also maintain a more even temperature between upstairs and downstairs. This will SAVE you MONEY because the outdoor condenser will not come on as much!
(3) Make sure that you wash the outside condenser coil once a year. If it's dirty, the A/C will run hot and inefficient. A sign of the coil being dirty is the small exposed copper (pipe) (tubing) line, usually 3/8" O/D connecting the inside unit with the outside unit will be HOT to the touch.
(4) If the small exposed 3/8" copper pipe connecting the inside unit with the outside unit is hot to the touch there can be several reasons why;
(a) A/C is low on refrigerant (b) The outdoor condenser coil is dirty. next page >>
