"Excellent. I can't say enough about how pleased I am with Southern Air Mechancial LLC for my Air conditioning service needs. Out of habit, I had been using another vendor who recently told me in the last 10 days that my unit was oversized for my duct work, that it was going to take 6 hours to fix it, and was about to sell me a part with installation and labor that would have cost $1400. The tech said it would break in a year and the owner basically tried to sell me a new AC unit. Got a little suspicious after asking if my unit could be adjusted since it was a variable speed down to a 3 ton and the owner said, "well, let me send my tech again". I called Southern Air and spoke to Clint, the owner. I had purchased the unit 7 years ago and without hesitation, Clint visited with his technician, and replaced the part that was a known problem with my manufacturer. He warrantied the part and was back out in two days and had the system cooling within 2 hours. I will only use Southern Air Mechanical and now know how trustworthy they are and what excellent service they provide. You can't and will not go wrong by choosing Southern Air Mechanical for your AC needs."

Air Conditioning FAQs, answered by experts

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork.
