A lot of things can go wrong with your cooling system, however first, it can get dirty, have you checked your air filter recently? The air filter is responsible for stopping dust & dirt getting into the system, if you don’t properly scrub it, then your AC gets stopped up with dust.
- It works sluggishly & ups your energy bills.
The dust is also bad to breathe in. Has your AC started leaking water? That might be an issue with the condensate drain. It can clog with algae & cause it to overflow with water. It is quite simple to muck it out & dump vinegar in the machine! Another problem is mildew on the cooling coil. Again, an simple repair & totally necessary, and your AC also can definitely cause high energy bills, make sure you take care of your air conditioner. I highly request getting yearly cooling service; Some people even do it two times a year. First an air conditioner tune up in the Springtime is necessary. This is a check up on all the moving parts where the HVAC company can add lubrication, scrub off debris & update any worn pieces. Then the air conditioner is superb to go for the season & will run efficiently; Before you turn off your AC for superb in the fall, have the HVAC company look at it again. It is possible a repair could have formed or mildew is deep in the system. You want to ensure it is in superb shape. The better shape your AC is in, the lower the energy bills.
