What Causes an Air Conditioner to Blow Hot Air?

The lucky thing here is there aren’t actually that many sources for this particular issue. This means a professional can locate and remedy the issue quickly and effectively! The most common causes you might look to as an explanation include:

  • Poor or weak air flow. When air flow becomes a problem, your system might not blow hot air per se, but it will certainly be rendered incapable of providing adequate cooling for your home. Poor air flow is a common problem and may be brought on by a malfunctioning blower motor, dust and debris caked into your system, or simply an old and dirty filter. We’d recommend checking your filter first to see if that’s your cause.
  • Exterior unit malfunction. The outdoor unit, the heat pump, plays an integral role in providing the cool air you’re accustomed to, and any problems with it can lead to warm or hot air blowing into your home. As a quick check, first see if your outdoor unit is clogged up with leaves and debris. If so, a good stiff broom may be the only remedy you require. If not, the problem is more likely component failure or issues with exterior power, which will require the expertise of a specialist.
  • Refrigerant leak. A lack of refrigerant in your system can lead to a wide variety of problems, including system freezes and warm or hot air blowing in from your vents. These leaks can be very obvious but occasionally go entirely unnoticed by the homeowner for far too long. If you’re having trouble, call on a pro right away before your repair becomes an air conditioner replacement!

The Simplest Answer

This might sound silly or potentially insulting, but before you call in the experts be sure your system is set to “cool” mode! It’s a surprisingly common cause, and checking that nothing on the thermostat has been accidentally tampered with could potentially save you a costly repair visit!
