"communication I found was poor. I felt I needed to reach out to them instead of them reaching out to me when I was the customer. at one point, figured I had not heard from them and was ready to just find someone else. I had to call them and when I did reach them wasn't even sure they knew who I was. they gave me a quote on 2 unit choices with nothing more than the price and the manufacturer, I had to call them to get more info on the units and do my own research. other than communication, things went well, clean, on time, polite, fair price,"

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"

"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

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.
