"John has taken care of all my HVAC needs for over 15 years. It's always an easy decision for me . . . I would not use anyone else but Admiral Heating and Air Conditioning, and I have recommended John to many friends over the years. My father was a home builder and I am an engineer, so I know what to look for in terms of professionalism, doing the job right, pride in one's workmanship, attention to detail, and treating the customer fairly and with respect. John and his company excel in all these areas. Thank you John for another outstanding experience with the install of the new American Standard heating and cooling package."

"⭐️⭐️⭐️⭐️⭐️ Top-Notch Service from Air Specialties Indoor Air-Quality Experts! I had an outstanding experience with Air Specialties Indoor Air-Quality Experts! From the moment they arrived at my home in Oakdale, TN, the team was professional, courteous, and clearly knowledgeable. They didn’t just clean the air ducts — they went above and beyond by identifying and repairing extensive rodent damage that I didn’t even realize was there. They sealed all the entry points, replaced damaged ductwork, and thoroughly sanitized the entire system. The before-and-after photos were shocking in the best way, and the difference in air quality was immediate — the air is fresher, there’s less dust, and even my allergies have improved. They treated my home with care, kept everything spotless, and explained each step of the process clearly. I highly recommend Air Specialties to anyone looking to improve their indoor air quality. Truly a 5-star experience from beginning to end. – Jeromy Brutcher, Oakdale, TN"

"I cannot share enough good things about Martin with CM Walter Heating and Air. We recently had a routine AC check done and our AC unit was really noisy after and not functioning like it should. We called CM and he came out same day within the hour of the phone call and spent the entire day making sure our unit was fixed. He is extremely professional and kind- even took his shoes off before he came in the house! We will absolutely be using him for anything that pops up in the future! Don?t look at anyone else, call now!"

"Greg came on schedule and discussed the project with us. He suggested LED pancake lights and dimmer. We originally planned to put in lights on either side of the room. He e-mailed a price by the end of the day. It was a fair price but over our current budget. We really only needed the lights on one side of the room (over the new office area), so I asked Greg to revise the estimate. It was not trouble and he did not try to push me into the original quote. We agreed on the price and he scheduled the work. Brennan came promptly and even texted me when he was close by so I could put the dog in another room. He completed the work very efficiently, cleaned up everything and was just awesome really. Everything is wonderful!!! I have found my electrician from now on!!!"

"They came into my mothers older home and explained everything they were doing, step by step. They replaced her unit and made improvements to her air ducts. They were honest and courteous! They left her feeling comfortable and safe and as if she were being treated like family. I cannot speak highly enough of Premier Services Group! I highly recommend this company!"

Affordable also - one doesn't feel like you are being over charged. Fair to the customer. Wish him the best success for the future and will use service again and will recommend to anyone. Thank you Anthony for your help. Life saver."

Air Conditioning FAQs, answered by experts

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

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.
