Help! My Air Conditioner Is Blowing Warm Air!

thermostat-going-redNo doubt, you’ve had cause to run your air conditioning system by this point in the year. Well, things are not going to be cooling back down anytime soon. At least not during the daylight hours. That is why you need to know that your air conditioner is going to be there for you when you need it most. Unfortunately, there is just no way in which to guarantee that your air conditioner is always going to function properly. At some point, you are going to run into air conditioning problems. One of the most alarming is a system that is blowing warm air.

There are a few silver linings when dealing with this particular problem, though. First of all, it is an obvious sign that something is wrong. That gives you the opportunity to resolve the problem promptly. Secondly, this problem, alarming as it may be, is not necessarily the result of a serious issue—though it could be. We have a few tips regarding benign causes of the issue, and some advice if there is no obvious cause. Remember to leave any necessary AC repairs in Trion, GA to the pros on our staff. 

A Few Items to Check

Shy of a complete system breakdown, an air conditioner pumping warm air into your home is probably the most obvious sign that something is wrong. It may not be something terribly wrong, however. This is going to sound obvious, but always remember to check your thermostat if you feel warm air coming from your vents.

It is entirely possible that you have accidentally switched your system over to a fan-only mode, which will leave it to recirculate warmer and warmer air throughout the house. You may also have switched your heat pump over to its heating mode accidentally. In either case, you don’t really need a professional service technician to adjust your thermostat for you.

You should also check to see if your outdoor unit is actually running when warm air is coming from the vents in your home. Your indoor unit and outdoor unit are likely—almost certainly—running on separate circuits. That means that a tripped breaker could leave one or the other operational. If the outdoor unit is on a broken circuit, the indoor fan may be blowing unconditioned air throughout the house.

It’s Not Always So Easy

Those are definitely best-case scenarios, and this won’t always be the case. Your system uses refrigerant in the cooling process, which is evaporated in the indoor coil in order to remove heat from the air surrounding and passing over it. If you have a refrigerant leak, this operation is impeded. Continuing to run a system that is low on refrigerant could result in major, even irrevocable damage to your compressor.

You could also have compromised air ducts. If your ducts are leaking, your system could be pulling warm air from different points in the house into the system. That air is then distributed throughout the house, tempering the cooler air that the system should be distributing. Professional duct sealing will be required to resolve such issues.
