Why Is My Air Conditioner Blowing Warm Air?

We expect a lot from our air conditioning systems here in Northern Virginia. We expect them to provide cool, high quality air—and we expect them to be able to keep up with our demands as the season goes on. But one thing we don’t expect is for the system to begin blowing warm or hot air. Got a misbehaving cooling system and not sure where to turn?

The certified air conditioning experts at John Nugent & Sons weigh in with the most common causes for warm air from your system. We’ll go over what can create this problem and what you need to do to ensure your system performs properly year round!

Reasons Your AC Is Blowing Warm Air

It’s a fairly specific problem, so you’d probably expect it to have a very specific cause. But the truth is there are actually a few potential issues at work here, many of which necessitate professional repair:

  • Operator error. It might be a startling cause and even maybe a bit embarrassing, but either through accident or miscommunication, this is actually the number one cause. Mistakes are made sometimes! Check your system carefully before calling in for costly repairs. See that it is absolutely set to “cool” instead of “warm”. Sometimes a stray shoulder-bump or a bit of forgetfulness can be the source of your troubles.
  • Refrigerant leaks. Your system utilizes refrigerant to perform its job, cycling the product form a gas to a liquid, then back to a gas as it goes about its work. When you have a refrigerant leak, your system doesn’t really have a way to know that the problem is there. This means it just goes about its operations, continuing to demand the same efforts of whatever refrigerant in your system. This can result in your system blowing poorly cycled, warm air. Also, the reason we say “leak” instead of “low refrigerant” is that your system never actually uses up refrigerant. The only thing that can alter the amount in your system is a leak.
  • A clogged outdoor unit. Going outdoors and checking the exterior unit might provide you with the cause. Are dust, debris, and leaves choking the fins of your unit? If so, this is altering the air flow in your system and killing its ability to provide cool air to your home.
  • Poor electrical connections. Electrical failure is a common cause of a wide number of air conditioner issues. If the breaker for your outdoor unit has flipped, then your system will refuse to operate. If the blower motor has a poor connection, you’re likely going to experience warm air in the home.

Avoid Warm Air With AC Maintenance

To ensure your system never encounters the problems listed above, our experts recommend that you seek professional maintenance on a routine basis! High quality cooling system care will ensure you never experience a refrigerant leak, or if that one occurs, you’ll have the care you need, when you need it most.
