Customers say: Quality work

"I was in need of boiler repairs. Most plumbing companies I contacted wanted to charge by the hour plus parts. I found NY HVAC on Home advisor and phoned them speaking with Vinny. Vinny from NY HVAC was a true professional. He told me over the phone that I would get great work at the price he quoted. When he arrived, he explained everything in detail that should be done to my boiler and maintained the original quote he had given me over the phone even though he was adding in additional repairs for me. Just an overall nice guy and very clean work. It's tough to find an honest plumber that does great work and today I found one. I have already placed New York HVAC phone number in my phone as my go-to Plumbing company. There is a reason this company has solid reviews and I'm adding a 5 STAR to this review and will share my positive experience with friends and family looking for a great Plumbing Company."

"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."

"Joe was very respectful, personable and patient and explained what he would do and why to ensure our central air would finally work. It took ALL DAY but he installed an exhaust fan in the ceiling with attic ducts to draw out hot air, performed a chemical wash of the condenser, installed a wifi thermostat that required a new transformer and taught me how to use it. I LOVE being able to monitor indoor and outdoor temps on the app and I can see that our summer tenants are using it and that the AC is working great when needed."

Heating and Air Conditioning questions, answered by experts

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

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.
