An AC unit may be blowing hot air for many reasons, making diagnosing an exact cause difficult. Regardless of why your AC unit is blowing hot air, restoring your AC as soon as possible is essential so your home is comfortable and safe. Here are some of the most common reasons why an AC unit can blow hot air:
Refrigerant absorbs heat from the air, leaving it feeling cold. If your AC unit is low on refrigerant, it’s unable to chill the air, which results in hot air coming out.
If you think your refrigerant is low, it’s best to call a professional. Several things can cause low refrigerant. For example, you may have a leak in your system or a major issue with your overall AC system.
Your AC filter prevents debris and other materials from entering the AC system. However, this same debris can result in a clog in your filter. When your AC experiences reduced airflow, the unit will have to work harder and less efficiently, which can mean your system may not cool down the air entirely, and you have warm air coming through the vents. During the summer, you can change your filter once a month to keep your AC operating at its best.
Thermostats often blow warm air due to human error, such as accidentally leaving their system on heat instead of cool. While this may seem like an obvious mistake, it can cause confusion and frustration when warm air pumps through your vents.
To fix this issue, simply look at the thermostat and see what it says. Ensure the thermostat is in a cool setting instead of a warm or fan. You also want to make sure the temperature is low enough that you can feel a difference in your home compared to the temperature outside. With the press of a few buttons, your home should be cool in no time.
Sometimes, parts of an air conditioner, like the evaporator coils, can get too cold. When these coils fail to receive proper airflow, cold air builds up around them, making them less effective or even freezing them. Regular AC check-ups will often catch issues like these before they cause significant problems with your AC system. Bring in a technician to fix them so your AC continues to operate correctly.
Sometimes, your AC might blow hot air due to an issue with the outside unit. When the outside unit of an AC system loses power, the cooling process stops, but the interior system continues to operate as if the air is still undergoing the cooling process.
This issue can be easy to overlook, especially if the outside unit is the only thing that loses power. However, it is a good idea to consider power outages as you troubleshoot why your AC unit may not be working.
Sometimes, your AC may blow warm air even if the system still operates correctly. This issue can result from issues outside the main equipment, such as duct leaks. Leaks cause cold air to escape and warm air to enter your ducts. If you have a duct leak, it’s best to fix this issue as soon as possible, as it can make your entire AC system ineffective.
Another often-overlooked issue is when the return vents become closed or blocked. You can accidentally close these vents or block them with furniture, boxes or other items. A block like this reduces the overall airflow, and the entire system starts running poorly. Opening and unblocking your return vents is a simple solution. Open the vents and remove anything in front of them, and you may have cold air again in no time.
Like any piece of machinery, parts of your AC unit can malfunction. When the compressor malfunctions, the system can’t operate properly, resulting in warm air. Reach out to the professionals as soon as possible to ensure they accurately diagnose and fix the issue.
Air conditioners use a lot of power, making them more likely to trip the circuit breaker in your home. If your AC unit is blowing hot air or is off entirely, check to see if it has power before heading to the circuit breaker and flipping it back in place or replacing the fuse.
While it may not be immediately obvious, there is a connection between air conditioners and drains. AC systems require drains to remove excess water during operation, and if the drain becomes clogged, the water will remain in the air conditioner and cause issues. During scheduled HVAC maintenance, a technician checks the drain and removes clogs so your unit operates safely.
