"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."

"They were great! Family run business who were with us every step of the way. It took us a lot of time to decide on what ductless a/c units we wanted and exactly where we wanted them installed but Keith was so helpful working with our many requests and helping us save money to stay within our budget. Highly recommend these guys."

Heating and Air Conditioning FAQs, answered by experts

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

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.

A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you’ll have a more efficient unit that’s likely to last longer.
