Realizing your air conditioning unit has stopped cooling poses a serious problem when the weather outside is scorching. Air conditioners stop blowing cold air for a number of reasons, some of which fall into the DIY category. Others, however, require a professional touch. Below are some reasons for this common cooling problem and what to do about it.

What Causes An Air Conditioning Unit To Stop Cooling?

DIY Solutions

Determine if your air conditioning unit problem is an easy fix. Check the thermostat fan setting first. If it says “on” instead of “auto,” the fan is running continuously, even when there’s no air to cool. Switch to auto to see if the problem corrects itself. If it doesn’t, check the filter. A clogged, dirty filter limits how much air blows over the evaporator coils, resulting in insufficient air cooling. Keeping the filter clean avoids cool air circulation problems.

If neither solution solves your cooling issue, check the outdoor condenser unit. Remove any weeds, leaves, grass, and other debris covering the condenser to stop heat dissipation problems. The condenser releases hot air sent by the evaporator coil and cannot function properly if it’s always dirty.

Call your local HVAC contractor if you suspect a more serious cooling issue. A refrigerant leak, for example, requires professional handling since Freon® is a highly toxic substance. When it leaks, there isn’t enough liquid to absorb and cool hot air. Fan motor and compressor problems also require HVAC contractor attention to prevent further damage to the air conditioning unit. If the fan motor breaks, the fan can no longer disperse heat to maintain a cool home. An ineffective compressor impedes the refrigerant’s ability to circulate and therefore cool air correctly.

Low airflow from clogs or leaks can also cause water in the evaporator coils to accumulate and ice over, creating blockages that prevent air from cooling as it travels over Freon. And while you can clean these coils yourself, HVAC contractors have special chemicals providing the deep clean the parts need to function correctly.
