Why Is My Air Conditioner Blowing Hot Air?

When you’re battling the North Carolina summer heat, you need a high-quality air conditioner to keep your home cool and comfortable. But what happens when your air conditioner stops cooling your home down and starts blowing hot air instead? Read on to learn more about what can cause air conditioners to blow warm air and how you can resolve this issue.

4 Reasons Your AC Is Blowing Warm Air (& How To Fix It)

There could be a few reasons why your air conditioner is blowing warm air instead of dispersing the cool air you need. Resolving a few of these issues will require the assistance of a certified HVAC professional, but you may be able to fix one or two of these problems on your own.

Your Thermostat Is Set Incorrectly

We know, it might sound silly — but it would be even sillier to pay an AC repair technician to come to your North Carolina home just to change your thermostat settings.

The first thing you want to check is that your thermostat isn’t set to “heat.” You could have bumped the switch accidentally, one of your children could have played around with it, or any other number of accidents could have caused this. Make sure your thermostat is set to “cool” if you want your AC to blow cool air.

The second thing to check is that your thermostat’s fan settings aren’t set to “on.” While that might sound like what you want on a hot day, it’s actually not. If your fan is set to “on,” it will blow air through your vents whether your system is actively cooling your home or not — meaning it will blow out warm air when your AC isn’t running. You want your thermostat’s fan set to “auto” for it to only blow cool air.

If your thermostat is already set to “cool” and its fan is set to “auto,” then you may have one of these issues:

Your Outdoor Unit Lost Power

Your air conditioner is made up of an indoor unit (which blows air through your home) and an outdoor unit (which cools the air down). So, if your indoor unit is blowing warm air, it could be because the outdoor unit doesn’t have power and can’t cool the air.

Typically, if this is the case, either your circuit breaker tripped or you’ve blown a fuse. If you check your circuit breaker or fuse panel and you see that the circuit isn’t providing power to your outdoor unit, you’ve found the problem.

This issue will need to be resolved by a professional. You can call Air Experts to schedule an appointment in Raleigh, and we’ll resolve the problem and get your air conditioner back in working order as quickly as possible.

You’re Low on Refrigerant

If your air conditioner is blowing warm air, its refrigerant levels might be low. This usually means a refrigerant leak in your system. If that’s the case, your AC will continue to run and blow out warm air, trying to reach the temperature you set on your thermostat.

Your best bet is to contact Air Experts to come and figure out where the refrigerant leak is, so we can repair it and get your system up and running again. We’ll fix the leak, restore your refrigerant levels, and leave you 100% satisfied with the solution — guaranteed.

Your Evaporator Coils Are Dirty

Your evaporator coils are a crucial component of your air conditioner’s functionality, and it’s hugely important to keep them clean so they can work to keep your unit running properly to cool your home. If you forgot to schedule your annual AC tune-up, there’s a chance your evaporator coil is coated in dirt or debris, which can keep it from blowing cool air.

To resolve this, schedule air conditioner maintenance to get your system tuned up, cleaned up, and ready to cool down your home.
