"Airco is a great family-owned and operated business, very fair and knowledgeable. They replaced our forced air central heating system (oil) in a day, and were quick to respond and get to work despite how busy things were during the January cold-spell. I would highly recommend for your heating and cooling needs!"

"New England Quality Air Solutions is a small family-run operation. our ducts hadn't been cleaned in a few years and I needed to have it done before going in for a lung transplant. Debbie in the office called me right back and gave me a very detailed quote. I scheduled the duct cleaning, along with cleaning the dryer vent. Debbie gave me a window during which the workmen would arrive and that they would call when they were on their way from their previous job. They called and showed up right on time during that window. Mario and Sergio explained how they do the work, verified the number of vents, mains, and returns, and were able to do most of the cleaning from the basement, using a rotating brush and vacuum. Then they went to each room and inspected those vents to ensure that they were clean. They showed us pictures of what was in the vents! They also did a treatment for mold, mildew, etc., and made sure I was not in the house for the few minutes that the treatment was being done, due to my lungs. Their pictures of the dryer vent showed almost complete clogging and they cleaned that also. I found them very professional and thorough, both in their explanations and in their work. I will definitely use them again and will recommend them to everyone."

"Everclear called near immediately upon my query through Angi. The technician came out within a few days, was very prompt on the scheduled appointment and took care of my dryer service. They were very reasonable in my opinion and would highly recommend them on all counts."

"My central AC unit has been broken for several years. intermittently working during hot summers. I've had several HVAC companies come to diagnose and all of them told me different things: replace the whole system, new lines, etc. potentially costing tens of thousands of dollars. So I decided to troubleshoot by myself and pinpointed the issue: the filter dryer needed to be replaced. No company wanted to do this small job. I called Emerald HVAC and told them about my issue, they sent in José, who diagnosed the issue to be what I said. He replaced the filter dryer and the AC unit works perfectly now after several years! In short, Emerald HVAC will be my first choice for any HVAC work in the future. They are honest, professional, and reasonably priced. I recommend them without reservation!"

"I recently had my air ducts cleaned by Pro Air Duct Cleaning, Inc and was extremely impressed. The technicians, were professional, prompt, and thorough. They used specialized high-powered vacuums and explained the entire process as they went. They even showed me before-and-after photos, which made a huge difference in seeing the results. The area was left spotless, and the air quality in my home is noticeably fresher—it’s like the house can finally breathe again. after their thorough cleaning, the difference is night and day. The crew was courteous, and were very respectful of my home. They didn't just clean the vents; they ensured the entire system was running efficiently. Truly a job well done!"Excellent work and highly recommended!"

Air Conditioning questions, answered by experts

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).
