3. Wrong Thermostat Settings

This is the most common cause of air conditioning issues and is fortunately a very easy fix. Double check your thermostat settings and make sure it’s set to “cool” and “auto”.

A good way to keep your compressor is good condition is to run you’re A/C for 10 to 15 minutes once a month, regardless of outside temperature.
