"After getting quotes from a few companies for a new A/C systemI decided to go with Weathershield.  Their price was very fair and they were very professional.  Air conditioning works great. When the A/C went in an condo I own I called them. They did me a big favor and did the work up in Palm Beach county which is an area they do not usually service.  Again, everything went perfectly.  The A/C works great. The office manager Christine is a total sweetie and so helpful. Just called them to clean our dryer vent, so happy they provide that service, I wouldn't trust anyone else.... Thanks guys!

"Skyline HVAC did an excellent job installing my AC. The installer was professional, on time, and clearly knew what they were doing. They explained the process, worked efficiently, and made sure everything was installed cleanly and correctly. Before leaving, they double-checked that the system was running perfectly. My AC works great and I’m very happy with the service. I’d definitely recommend Skyline HVAC to anyone needing quality HVAC work."

"I have have several bad experiences over the years with people/companies that have been consulted or hired for home projects and repairs. Breeze Air Heating and Cooling offered a reasonable price for work done. They were reliable, quick, professional and did quality service/work. They have gained a new long term customer. I definitely recommend."

"I cannot say enough good things about Happy Ducts HVAC solutions. I used them a few months back to clean the air ducts in my home and was beyond impressed. Since then I have hired them to do all of my restaurants as well. They are extremely professional, do an immaculate job and have upfront, honest pricing. I had about five other companies bid on my restaurants to clean the air ducts and Happy Ducts was the clear winner when it comes to price, reputation and service. There is no need to look any further. Hire these guys for all of your HVAC needs."

Heating and Air Conditioning questions, answered by experts

Yes, it’s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your AC runs all the time, your system’s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills.

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.

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

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.
