"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

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

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.

Yes, the furnace and AC use the same blower. The blower is located in the base of the furnace and pushes hot air out of the furnace and into the ducts. It also pushes cool air through the home when the air conditioning is on. Even though the furnace and air conditioning work independently of one another, the blower is an essential component for both systems.

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.
