"Eric showed up for the estimate on time and called back a few days later to check in. Eric and his crew replaced my central air today. They showed up on time and got right to work. The install went quick and it looks professional and neat. Will recommend him to anyone needs HVAC."

"The guys at MassAir made having to get new central AC units installed, repairs on older units, new vents and ductwork, etc., actually a pleasurable experience! It is a family owned business, and I found Joe and his son Michael to be a real pleasure to work with. They are an extremely professional, proficient, knowledgeable, honest and hardworking team, and I trust them with any HVAC related projects that I have in the future. I 100% recommend giving these guys a call for your HVAC needs! -Mike Vedder"

"The AC was installed in 2021 replacing an existing AC. It worked well for two seasons but I n the beginning of this season 2024, I had problems. Although the technicians that came were nice, they did nothing to fix the problem until Christian who worked tirelessly. In the future I will only ask for him. The reason for the rating is because their customer service is very good, however, I went nearly the entire summer with an AC that was malfunctioning because the first two techs could not find any problem. Also, I find their repairs costly. An example is that I paid to be in a program where they inspect electrical plumbing and hvac. No recommendation was less than $500. In fact my son used them to replace two hoses in the kitchen. Starting price for anything seems to be $500 even if they are there for 30 minutes. The choice is yours. very good customers service, nice but mediocre techs (except for Christian) and costly repairs."

"Kyle installed my AC system in 2023 and I have nothing but good things to say about him and his company. I had him come back recently to trouble shoot my heating system and he really went above and beyond what I expected. I would recommend this company for any of your HVAC needs."

"Jonathan Moya is the owner of the company. My wife and i decided to finish our basement as an extended living space. We asked for three estimates for ac and heating, and mini split systems were recommended. Jonathan Moya and comfort duct systems, was the only company that explained the deficiencies in such a system as compared to central ac and heating. He explained the pros and cons of each system- In fact, the mini split would have cost us more money! My overall experience has been nothing but positive. I found Jonathan to be honest, knowledgeable, and extremely proficient and reasonable. I was confident from the moment that I met him, and after he completed the installation of my central AC unit for a 2000 square foot basement, it confirmed my initial instincts- Jonathan is simply the best at what he does. Please believe me, because I have worked with countless HVAC so called professionals over the years, and not one of them has impressed me the way Jonathan and his company has- I will never hire another HVAC company again- these are the guys you want in your home. I give Jonathan Moya and his crew my highest recommendation. You will not be disappointed! Sam M. From Oyster Bay , NY"

Heating and Air Conditioning questions, answered by experts

Though it may seem redundant, you can absolutely have a central AC unit and a window AC in your home. In fact, if you place a window AC unit near your central air, it can help move the cooler air throughout your home. But doubling up on your AC methods can get pricey, so factor in cost accordingly.

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Your heating and cooling systems cost you the most on your electric bill and make up 50% of your bill on average. Your washing machine, dryer, oven, and stove contribute significantly to your electric bill as well. Lights, fans, and smaller electronics add up, but aren’t the biggest energy consumers. You can reduce your power usage by setting optimal temperatures on your thermostat and investing in energy-efficient appliances.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.
