Air conditioners have their work cut out for them in North Carolina during the summer. Our combination of humidity and high temperatures make air conditioning a requirement if you want to be able to sleep at night or focus at work. As a result, air conditioners are some of the hardest-working appliances in Charlotte, and the certified professionals at James Brown Air Conditioning & Heating are proud to play any part in keeping Charlotte’s AC units running strong.

We have over two decades of experience in HVAC repair, and in that time, we’ve seen AC units get a lot smarter. We’ve also noticed several issues that continue to stick around, common trip-ups that affect a majority of air conditioners. In today’s blog, we are going to share a few of the most common culprits responsible for air conditioner failure. Read on!

Refrigerant is running low.

Refrigerant is a powerful chemical that actually cools the air within your air conditioning system. If you’ve got air coming out of the vents but it isn’t cool, chances are good that your refrigerant is running low. Generally, the only time refrigerant runs low is when it’s leaking out of the unit. Refrigerant leaks must be fixed quickly, not just to get your unit running again, but because refrigerant is actually a dangerous chemical that can only be handled by certified experts. Our team is fully certified and ready to solve any refrigerant issues you have.

The wiring is bad.

Your system may have been wired incorrectly when it was installed. Whether the bad workmanship happened before you moved in or was done by an HVAC team you thought knew their stuff, we can redo the wiring. You won’t have to deal with an air conditioning system that trips your circuit breaker or doesn’t get power at all. Best of all, your air conditioning wiring will no longer be a fire hazard. Bad wiring is just a fire waiting to happen, and you should never leave it as-is.

The outdoor fan isn’t functioning.

Your air conditioner depends on a fan to pull the hot air out of your home so it can cycle cooler air in. When that fan stops working and hot air is no longer leaving your home, the air conditioner unit can no longer function correctly. It will overheat and may have to turn itself off, which is the best scenario. In the worst scenario, your compressor may be damaged on the inside, requiring expensive repairs.

The coil has frozen up.

The coil in your air conditioner is responsible for cooling the air that gets piped into your home. Therefore, it has to stay very cold! However, the incoming warm air creates a delicate temperature balance that prevents the coil from freezing itself. When coils do freeze up, it’s usually either because the refrigerant is low or warm air isn’t getting to them. The air generally gets blocked by clogged air filters or stopped-up ductwork, which usually indicates bad air quality. You’ll want to get a professional assessment of your HVAC system before moving forward.

The outdoor unit isn’t working.

If the part of your air conditioner that stays outside doesn’t even turn on anymore, it’s generally because of one of the following three reasons. There might be no power going to your unit, which is the simplest and often most obvious issue. On the other hand, you might have a thermostat malfunctioning, telling the unit it doesn’t need to turn on. Lastly, your unit might be suffering from contactor problems and require professional attention.

All of the above issues can be quickly addressed (and prevented) by regular professional maintenance. Contact our certified team in North Carolina today!
