"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to up-sell me on services, a new machine and tell me all the new things I needed; instead, he told me the machine is outdated, but working properly.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

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.
