Thermostat |
The batteries in your thermostat may be dead, or the thermostat may not be on the correct setting. |
Put new batteries in your thermostat and ensure that it is on the cool setting. |
|
Circuit breaker |
The breaker switch may have flipped. |
Move the breaker switch back to the “on” position. |
Not blowing cold air? |
Air filter |
If the filter is clogged with debris or dust, it won’t be able to do its job. |
Replace or clean your air filter so that air can flow freely. |
|
Outside unit |
The air conditioner may not be able to have air flowing freely if there are dirt and debris around the unit. |
Make a two-foot space around your unit that is clear and free of leaves, greenery and any other blockage so that it can vent air properly. |
|
Refrigerant |
If the refrigerant is leaking, your unit will not be efficient at cooling since there is less cooling fluid to run through your unit. |
Get a technician who can solve this problem. |
|
Insulation |
Insulation is important to keep air from leaking out. Cracks, old windows and doors are all spots where cold air can escape. |
Windows are the main places where cool air escapes. Consider upgrading to insulated windows or use blackout curtains. |
Dripping water? |
Condensate line |
The pipe that exits your air conditioner could be clogged. |
Blow compressed air through the pipe to dislodge the clog. |
|
Drain line |
Water can overflow in the drain pan if the drain pipe is blocked. |
Check the drain line for any clogs and remove them. |
Making odd sounds? |
Blower motor or belt |
Squealing sounds can come from the belt or the blower motor. |
Use lubricant on the parts to help them run better without squeaking. |
|
Fan blades |
If the sound is repetitive like a card stuck in a bicycle spoke, there is a chance something is caught between the blades. |
Switch your unit off and check the fan blades to see if anything is trapped and remove it carefully. |
