Why is My AC Running, But Only Producing Hot Air?

When the weather in the Greater Atlanta, GA region turns hot and humid, an air-conditioned home surrounds you with cooling comfort. The last thing you expect to encounter when you’ve got the AC running full blast is hot air blowing through the vents. The following troubleshooting tips can help fix the problem when your AC system fails to produce cool air.

Thermostat Problems

First things first, check your thermostat and verify it’s set to the correct mode. If you’re unsure what mode it needs to be on, contact a qualified HVAC professional to resolve the situation. Whether the underlying issue is faulty wiring or the thermostat itself, a qualified HVAC contractor will set things right.

Dirty Components

Whether it’s your AC system, a ceiling fan, or the vent above your oven, anything that moves air around eventually gets dirty. The buildup of dust and debris on critical parts can make it impossible for your cooling system to work properly. Here’s what to do to keep components clean with the AC running.

  • Check the metal fins on the outdoor unit to confirm that leaves, lawn clippings, and other debris aren’t blocking the free flow of air.
  • Changing the filter whenever it’s dirty (or better yet, every three months) helps keep everything operating efficiently, saving you up to 15% on cooling costs.
  • Sign up for regularly scheduled maintenance with Ful-Bro Heating and Air Conditioning Inc., and we’ll replace the filter and clean the entire system for you.

Low Refrigerant Charge

Air conditioning systems use refrigerant to retrieve heat and, from there, move it outside. When first installed, the precise amount of refrigerant is “charged” into the system. Over time, leaks can occur, making it impossible to keep the air cool. If you notice signs of leakage, you’ll need a NATE-certified technician to fix it and recharge the system.
