Why is my AC running but not cooling the house?
our air conditioning may be malfunctioning because of an electrical problem within the unit itself, but there are some other common causes as well. For example, you might not have enough refrigerant or there might be a leak. The air registers (floor vents, wall grates, etc.) may be closed. The air filter on the furnace or unit may be old or clogged and need to be changed. The outdoor condenser coils may also need a wipe down, which is recommended every few months.
If you cannot identify the problem in one of these quick fixes, it’s best to contact a pro near you to assess and fix the problem.
