If there are gaps in your home’s wall, ceiling, and floor, it could mean that warm air penetrates inside and has to be cooled by the AC unit. This means that the AC has to work harder and use more energy than necessary to cool down a room, which could lead to problems or even breakdowns.

Dirty filters can also make your AC unit run harder, causing it to break down.

The filters on your AC unit play a significant role in keeping the air inside your home clean and healthy. Dirty or worn-down filters can cause the AC unit to run harder, causing it to break down faster than usual.
