"I give Coast to Coast Heating and Air my highest recommendation. They did the most thorough residential HVAC installation estimate I’ve ever seen. They identified several issues that needed to be addressed that caused our previous unit to fail prematurely and fixed them as part of the installation. For the friendly, amazing and honest service we got I expected to pay quite a premium—but even their quote was competitive."

Before and after. Along with installing a new Tem4 air handler, we re-built the air handler stand to our liking. It was re-insulated with new fiberglass ductboard and completely mastic sealed. We also make sure our copper looks amazing on every job. No hand bends!

"Leahy Heating & Air Conditioning did an excellent job with our HVAC installation. From the beginning, they were honest, professional, and easy to work with. The pricing was fair and clearly explained, and we never felt pressured or pushed into anything we didn’t need. The install was clean, efficient, and done with great attention to detail. I would highly recommend Leahy Heating & Air Conditioning to anyone needing a new AC system, heat pump installation, or HVAC service in Gainesville and the surrounding North Central Florida area."

"Very accommodating. Crew was professional and friendly. They replaced my entire HVAC system including ducts and supply vents in two days. Scheduled so we had air overnight and were almost invisible and silent. Hardly knew they were there."

"My AC unit went out, and it was a blistering 86° inside of my house. My kids and dog were not happy at all. I called Sunshine Services and spoke with Faith. I explained the situation to her, and she had technician Shane Nase come out to assess the issue almost immediately. Shane was here for about an hour and got me back up and running with AC. THANK YOU FROM THE BOTTOM OF MY HEART!!! Highly recommend Sunshine Services for your needs!"

"I called Ray's and was able to set up a time quite easily. They provided a time range for the technician to show up; mine was 3-5pm (technician showed shortly after 3). Technician's name was Rod, he was very professional and insightful. He didn't mind me lingering around, shared details on what he was doing and answered my questions. I live in a very old house and the HVAC unit is probably a bit over 20 years old. I was anticipating Rod to up-sell me on services, a new machine and tell me all the new things I needed; instead, he told me the machine is outdated, but working properly. He informed me it would be in my best interest to buy a new part for the outdoor unit (the name slips my mind at the moment), but didn't pressured me with sale pitches or scare tactics. The outdoor unit was filled with dirt and debris that had fallen into the machine over the years; Rod took the time to thoroughly clean through the machine with my hose (I mean literally, he was taking pales of dirt out). I was quite pleased with the experience and would use them again.

Heating and Air Conditioning FAQs, answered by experts

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

Yes, it’s normal for an AC to drip water. In fact, it’s part of the dehumidifying process that takes place inside your AC unit as the condensation trickles down into the drain pan. However, it isn’t normal for your AC to sound like it’s running water or have large puddles around it. If that happens, you can try the solutions listed above or call an AC repair pro.

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.

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.
