When you turn on your AC during the summer, you expect to sit back, relax, and enjoy the cool air. After all, our air conditioners are designed to keep us comfortable even on the hottest days. However, these trusty systems can experience issues from time to time, such as when they blow warm air instead of cold.
Why is your air conditioner blowing warm air? Several factors can cause this problem to appear, and getting to the bottom of it can take some troubleshooting. To help you fix the issue quickly, let’s dive into the potential reasons your AC is blowing warm air.
A Faulty Thermostat
First, if you want to understand why your air conditioner is blowing warm air, turn to your thermostat. It’s possible that a faulty thermostat could be to blame. Your thermostat’s sensor could be experiencing issues that make it difficult for the AC to cool your home properly. However, it’s also possible that you simply have your thermostat on the wrong setting.
How To Check the Thermostat Setting
While it might seem simple or silly, the wrong thermostat setting could be one of the potential reasons your AC is blowing warm air. Whether it was an accident or a family member changed it on purpose, your thermostat could be on the wrong setting. Check to make sure that the thermostat is set to “cool” and the fan is set to “auto.” Fortunately, adjusting your thermostat is a quick and easy fix that can restore your comfort in moments.
A Dirty Air Filter
Don’t overlook the importance of a clean HVAC air filter. Believe it or not, a dirty air filter could be why your air conditioner is blowing warm air.
Ask a professional HVAC technician how often you should replace AC air filters, and they will say at least every 90 days. Otherwise, your air filter can become clogged with dirt and debris. Clogged or dirty air filters can restrict airflow and negatively affect your HVAC system’s performance. As a result, you might find yourself paying higher energy bills. When it comes to ACs blowing warm or cool air, simple upkeep such as replacing the filter can make a world of difference.
A Refrigerant Leak
If you have an AC unit blowing hot air, check the refrigerant levels. Your air conditioner needs refrigerant in order to make your home feel cool. However, with a refrigerant leak, you won’t receive any of that refreshing, cool air you so crave. Refrigerant leaks can also cause a blown fuse or tripped circuit breaker since your AC is trying to work extra hard to keep you cool.
While a refrigerant leak is one of the most common reasons your AC is blowing warm air, don’t attempt to fix the problem yourself. You should always call a Springfield, IL, AC repair specialist to remedy the issue.
Frozen AC Coils
Believe it or not, frozen evaporator coils could also be why your air conditioner is blowing warm air. Refrigerant leaks, as well as clogged air filters and dirty evaporator coils, can cause AC coils to freeze. As ice builds up on the coils, your air conditioner will start to experience a wide variety of issues, including the inability to provide cool air.
A Lack of Maintenance
It’s no secret that your air conditioner requires routine maintenance to remain in peak condition. Otherwise, you might find yourself paying for frequent repairs or a premature replacement. If you’ve been putting off maintenance, this could also be one of the potential reasons your AC is blowing warm air.
Many parts of your AC can suffer from a lack of maintenance, including the condenser coils. These condenser coils are a part of the outdoor condenser unit and are constantly susceptible to dirt and debris. When this dirt and debris can build up, a malfunction can occur.
