Common Reasons Why AC Unit Running But Not Cooling

Why does it feel hot in the room even though the AC is ON? Is the AC unit running but not cooling normally? If these questions come to mind whenever you come home or at the office, then there might be a problem with your AC unit. Before you go and buy a new AC unit, try to clean the old unit first. Most of the time, it is just a matter of maintenance and care. However, if the problem still persists, a more thorough inspection should be done to diagnose and resolve the problem.

Here are some common reasons why an AC unit is running but not cooling air:

  • Stalled condenser coil – This is the part of the air conditioning unit that produces cold air. If this is the case, you might want to call a professional to help you figure out and diagnose the problem properly. The condenser fan will run even when the condenser is not functioning properly. You might think that the AC unit is ON but lacks the flow of cool air so this might just be the case. Condenser malfunctions are commonly cause by a tripped circuit breaker or a blown fuse.
  • Ductwork leaks – In most cases, the AC unit might not immediately be the blame. It is common for old ductworks and even new ones to sometimes have leaks. If a leak is present, then cool air might escape the ducts leaving a low supply of cool air. A thorough inspection of the ductwork will be needed to seal off any leaks found.
  • Low maintenance – With time, most appliances will eventually break down. However, it does not mean that they are permanently broken. It might just be a case of excess dirt. Try to clean your AC unit as often as possible. It will help your unit run smoothly and avoid any costly repairs or worse, buying a new unit altogether.
  • No power – AC units need electricity to run. Common problems like incompatible voltage sometimes come up if the unit needs a specific voltage to function on.
