Your AC issues moving air through the system. A fan blows indoor air over the evaporator coil to cool it, while another fan blows outdoor air through the condenser coils to expel heat. If a fan isn’t working correctly, the cooling cycle will be off and you won’t get cold air. This could be caused by a faulty motor, degraded lubricant, or wear and tear damage. The easiest fix is to make sure the thermostat is turned on, in the right mode, and that it’s set on the correct temperature setting.
If you hear squealing, hissing, grinding, or buzzing noises, it’s time to call in a professional. Squealing often indicates a loose fan belt, while hissing can indicate a refrigerant leak or compressor issue. Grinding and buzzing may be signs of an oversized unit that is straining the components to work harder than they should, which puts additional wear and tear on your system.
