It’s the middle of the hottest season of the year, and your air conditioner is blowing nothing but warm air. You need to cool your home down quickly. What could possibly be the cause of this sudden burst of warm air filtering out of your air conditioner unit? 

Fortunately, warm air from your HVAC unit in the summer could be an easy fix. Take a look at some of these top causes to see how you can resolve the issue quickly in this scorching heat. 

 

Incorrect Thermostat Settings

It may seem obvious, but you need to first check your thermostat for the proper settings if your air conditioner is blowing warm air. Someone in your home may have accidentally toggled it from cool to heat. If this is the case, you will experience warm air blowing into your home instead of the refreshing chill you have come to expect. 

 

Dirty Air Filter

When was the last time you replaced your air filter? This crucial aspect of your HVAC system is responsible for removing dust and dirt from the air. A dirty filter can cause a buildup of this debris on your evaporator coil. In turn, this leads to a frozen coil. It is a bit of a misnomer though because a frozen coil does not actually produce cold air. Instead, your air conditioner is likely to blow the warm air from the motor instead of the chilled air you want. 

 

Check for Electricity

Your air conditioner requires a steady stream of electricity to produce enough cool air to drop the temperature in your home during a hot summer day. If you notice warm air, one of the first things you should do is check the electrical panel. The breaker may have flipped if there was too much power flowing out to your unit. 

 

Head to the electrical panel or breaker box in your home to look for a tripped breaker. Try turning off the breaker that flows to the AC unit completely and then turning it back on. If it immediately flips again, you may need to contact an electrician to take a look at your box or to help you replace a fuse. 

 

Low Refrigerant

If the first three items on the list do not solve your problem, your warm air could be caused by low refrigerant. It might be leaking from a worn valve or a loose joint. This coolant is extremely dangerous and should only be handled by a professional. Never try to add more or solve the problem on your own. Low refrigerant is indicative of a leak somewhere in the system. Adding more coolant alone will not solve the problem.

Impeccable Quality and Professionalism…

Had them install our system when building and multiple other contractors commented on the impeccable quality and professionalism of their work and staff. Worked with them on another building project and had equally great service and quality. Used them on a service call and Mitchell was very timely, efficient, and professional. Provided explanation in detail of what had happened and fixed it quickly. VERY impressed with this company and would recommend to ANYONE in need of a system install or repair service.

I Knew I Made the Right Choice from the Word Go

Kurtis Hall dealt square and honest every step of the way. His knowledge of our dated system, new product information, project scheduling and communication allowed for a seamless installation at our vacation property without my having to interrupt my work schedule to accommodate the project. And living over 5 hours away that was a huge help to me. I knew I made the right choice from the word go. Excellent job Mr Hall! Will recommend your company to others!
