Hot summer temperatures mean it’s crucial to have a well-functioning air conditioner. When it’s not working properly, such as if it’s blowing warm air, it could mean unsafe and uncomfortable indoor conditions.
Common Reasons Your AC Is Blowing Warm Air
There are several common causes for your air conditioner blowing warm air. They range from easily fixable issues that a homeowner can handle to severe problems requiring professional attention.
Clogged Air Filter
A clogged air filter is one of the primary reasons that your unit might blow warm air instead of cool air. If this is the cause, it’s easily fixable without a repair appointment. Turn off the unit and pull out the dirty filter. Put the clean one in, start up the unit, and see if the AC starts blowing cool air once again.
Electrical Problems
Faulty electrical components within your unit may result in your air conditioner blowing warm air. Electrical malfunctions can prevent essential parts like the compressor from working correctly. Tripped breakers, humming noises, and short cycling are a few signs of an electrical issue.
Thermostat Malfunctions
A malfunctioning thermostat is an additional potential cause. If it’s not communicating properly with your system, your unit might blow warm air. Potential issues can range from miscalibration to corroded wiring.
Refrigerant Leak
Refrigerant leaks are another common reason. Some homeowners think that topping off the refrigerant will fix the situation. While it may work in the short term, we don’t recommend it. The best option is for a professional to determine the cause of the leak and perform a viable HVAC repair. Depending on the unit’s condition and the severity of the problem, an AC repair may not suffice. We may suggest replacing the unit, such as if it’s old or the repair costs outweigh the replacement price.
Blocked Outdoor Unit
The condenser is designed to release the heat absorbed from the inside of your home by the refrigerant. When it can’t do so freely due to an obstruction, warm air may flow from your supply vents.
Tips for Preventing a Recurring Problem
There are certain AC maintenance tips to follow that could help you prevent the issue from recurring. For example, you can regularly replace the filter. It’s best to do this every few months. However, during the summer, it’s ideal to change it monthly. This keeps dust and debris from accumulating to the point that it restricts airflow and causes warm air instead of cool air to blow out. Keep extra filters on hand in case you need to change yours promptly.
It’s also important to make sure that your outdoor unit has plenty of clearance around it. This may mean moving furniture, toys, and other items at least a few feet away.
Scheduling professional maintenance is also vital. We suggest booking an appointment in the spring for a comprehensive inspection and tune-up. Our team will inform you if we notice any problems to address before the peak cooling season.
DIY vs. Professional Repairs
If your air conditioner is blowing warm air, homeowners can attempt certain easy DIY fixes. For instance, you can change the filter and make sure there isn’t anything blocking the outdoor condenser. However, professional HVAC technicians should generally handle troubleshooting. This isn’t just for safety purposes. We also have the expertise and equipment to quickly determine the problem and how to fix it. This can reduce your AC’s downtime so you won’t have to be uncomfortable in a warm indoor environment.
Avoid using the air conditioner if it’s blowing warm air. This can allow the problem to worsen and potentially lead to more severe, costly issues. Shut the system off entirely and book an inspection. Until we can assess the situation, consider using options like window ACs, box fans, and ceiling fans to help stay cool.
Your air conditioner is an important part of being comfortable during the summer. If it’s blowing warm air, especially during extremely hot days, you’ll likely feel anything but. Don’t wait to request expert help. The sooner we address the problem, the faster your home can feel cool once again.
