"Pros like Kevin are hard to find - he serviced and repaired my 2 central ac units, came right away, diagnosed the problem real quick, was courteous and professional and the price was reasonable. I have experienced 3 different hvac companies and Kevin is hands down the best - very highly recommended!"

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"

Heating and Air Conditioning questions, answered by experts

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.
