Why Is My Air Conditioner Blowing Warm Air?

November 3, 2017

Why Is My Air Conditioner Blowing Warm Air?Colorado may not be the first place that people think of when extreme summer heat comes up. Sure, there are warmer areas of the country, but that doesn’t change the fact that summers around here are still plenty hot. If you want to make it through the summer season in anything remotely resembling true comfort, then you need to have a great air conditioner installed in your home. Unfortunately, even the best air conditioners — and even those that are properly installed and regularly tuned up — are not perfect.

Of all the issues that may develop with an air conditioning system, and AC that is blowing warm air is one of the most alarming. However, warm air blowing from your air conditioner in Denver, CO does not necessarily mean that there are serious issues at play. In fact, there may be a very simple solution to the problem that you can handle on your own. It could be something serious though, so it is important that you contact a member of our team if you can find no obvious fix.

Best Case Scenarios,/h2>
Let’s start off by keeping things a little positive. Here are a few items to check before calling in for professional air conditioning repairs. These problems are so simple to resolve that you definitely are not going to need a service technician’s help in order to get your air conditioner back on track.

First things first, go check your thermostat if you notice that your air conditioning system is blowing warm air. Yes, we know that this sounds obvious. When homeowners are thrown into a panic by a malfunctioning air conditioner, though, “obvious” solutions don’t always seem so obvious.

It is possible that your thermostat is set to a fan-only mode, and that will leave it to blow unconditioned air throughout the house. Basically, it is just acting like a fan. You could also have a heat pump accidentally set to its heating mode. In either event, you need only reset the thermostat to fix the issue.

You should also check to see if your outdoor AC unit is actually running. If it is not, check the circuit breaker. Your indoor and outdoor systems should be running on their own designated circuits. If the breaker for the outdoor unit is tripped, just reset it and your AC should start cooling air successfully once again.

More Serious Issues

Okay, now that we’ve covered the quick fixes, let’s talk about some more serious issues. If your system is running but is blowing warm air, you may have refrigerant leaks that need sealing. If the refrigerant level in your system is low, your AC will not be able to cool air effectively. Continuing to run your air conditioner with a low refrigerant charge puts it as serious risk of costly damages.

You could also have a problem with leaky ductwork pulling warm air into your HVAC system. If this is the case, then you will need professional technicians to go in and seal your ductwork. This is not a job that you can handle on your own.
