"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. In fact, not only are AC tuneups worth it, but they’re actually necessary to keep your air conditioner in good condition, improve its efficiency, and potentially prevent major damage. Experts recommend getting a tuneup at least once per year. In most cases, you’ll want to schedule it during the spring so that you can address any issues before the hottest months of the year.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.

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.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.
