"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."

"Metro Air did an excellent job! I highly recommend this company, especially Ron, my technician. At first I thought i just needed Freon , then thought it was a bad capacitor, come to find out I needed a whole new outside unit. The price was on the higher end of the spectrum when I googled comparable pricing, however the customer service I received was excellent. All care was kept in keeping my home, inside and outside, clean and tidy. Ron was prompt and pleasant to work with. They work on Sundays, and came out immediately when I called with my air troubles. Great company! Thank you Metro Air!"

"They visited my home and supplied me with a comprehensive report on my existing HVAC system, as well as several pricing options. When it came to carrying out the task, they were quite skilled, performed it quickly, and left the area clean. From customer assistance to installation, it was a positive experience throughout."

"I had a broken furnace (old, has exceeded its designed lifespan). Called in early @ 0900. Customer service was informative and professional. Reservation availability was 1 week. However, I asked to be on the wait list, and a technician was able to respond the same day. The technician was also informative and professional. He was able to do a quick repair and provide us set an objective expectation regarding the remaining lifespan of our unit. We've used their company before for a garage HVAC replacement and will continue to use it in the future. At the risk of sounding like a commercial... You might find a cheaper provider but you wont find one offering better value for your money than Clean air pro. We've used other providers when working through a home warranty service. The alternative companies didn't yield quality results, just temporary fixes."

Heating and Air Conditioning FAQs, answered by experts

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.
