Air Conditioners must have a filter , the filter will be located inside your home either wither with the equipment or behind a grill inside your home perhaps a hallway.Its is very important that the filter is hanged or cleaned regularly in order to filter the air properly and prevent the indoor coil from getting dirty.Filters will get dirtier faster if there are multiple pets,there is a dusty outdoor environment.if carpets are infrequently vacuumed.
Be sure to keep the outdoor condense clean.this means all sides should have nothing clinging to them.If you do see dirt, leaves, grass clipping, cottonwood, use a water hose with spray nozzle to rise the sides off starting at the power first.
During the summer, if you see fort on the outdoor or indoor pipes,your system is frozen and will not cool properly. The system must be thawed to solve this issue.the quickest way to thaw the system is to turn the AC off at the Fan to on.It may still take two hours to haw.
Do not set your thermostat below 70 degree. as it will not cool any faster and could freeze p the system causing more problems.
Understand that there is generally a 20 degree difference between inside temperatures.So when it is 90 degree outside,you can expect to get your indoor temperature to 70 degree if desired.
If you see water leaking from an outdoor pipe or pipe located above a bathtub, this means that your primary condensate drain has a problem and the water is traveling through the emergency drain system. This is usually located in a conspicuous area so that you will easily see the water dripping and know there is a that problem call for service.
