For emergency services, please call 781-933-6387. N.E.T.R., Inc. is here to help homeowners install the best heating and cooling systems that fits their needs. Since 1989, we’ve installed heating and cooling systems in Boston and its surrounding areas, tackling tough problems that our clients face. Our goal is to ensure our clients have energy efficient, quiet, reliable systems so they can live their lives to the fullest both at home and at work. Our dedication to our customers’ needs is what drives us each and every day. Our approach to temperature control and comfort has helped us become one of the most respected names in heating, cooling, and refrigeration in New England

"Before installing a mini-split, the sales person told me that I'd need to cut down an interior shelf to a specific height. I paid a handyman $400 to do exactly what the sales person instructed. Later on, N.E.T.R. came and did the installation; however, AFTER the installation, a technician told me that they hadn't accounted for the vent opening and closing and that the shelf would need to be further cut down. As you can imagine, this type of service is rather ridiculous. If they knew that the shelf would need further cutting, they should have NOT installed the unit. I have called N.E.T.R. six (6) times in three weeks, and no one has called me back about this issue. After paying for the unit and for a handyman, it's ridiculous that I have AC that is compromised because no one with the company thought to properly measure the space so that the work by the handyman could be done once. At this point, I'd like for N.E.T.R. to take care of this for me."

Providing residential heating and air conditioning maintenance, repair and installation of furnaces, boilers, heat pumps, ductless and high velocity AC. We are experts at providing air conditioning solutions for older homes, oil/gas to heat pump conversions, and are Mass Save certified heat pump contractors. We’ve built a reputation for superior quality, through years of putting the customer first and getting the job done right the first time. As local residents, our family and expertly trained team of technicians think of our customers as neighbors; our goal is to maintain our reputation as a quality organization, continuing to offer superior heating and cooling services in the Boston area and ensuring that you can be proud of our work and products for years to come.

"Diagnosis and repair were straightforward and the talented Mike, who has done other great work for us on our ACs, had a replacement pump in his truck. Swapped over in under an hour. Cost of the repair was quite high, mainly due to very high price they charged for the pump. A Taco pump that I could buy for $175 was priced on this repair at more than $500. I get that it was an urgent situation and I’m happy to pay reasonably for the response but that mark-up bothered me. I called the office, had a long talk with the owner; sadly, she offered no consideration at all. Yes, it’s hard to find and keep skilled techs, but now seems that most HVAC firms have a business model like a car dealer’s service dept, far more corporate, less flexible or customer-considerate."

Heating and Air Conditioning questions, answered by experts

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Yes, unfortunately, scorpions do come up through air vents on occasion if they’re not properly sealed. These pests are excellent at finding small openings and may use vents as a pathway to cooler areas inside, especially during hot weather. To prevent this, inspect your vents, seal any gaps, and install fine mesh screens where necessary.

Yes, it’s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your AC runs all the time, your system’s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills.

You reset your AC after a power outage by turning off the air conditioner from the thermostat, resetting the circuit breaker, waiting 30 minutes, turning on the AC from the thermostat, and waiting 10 minutes to see the impact. Sometimes, with a power outage, the AC needs time to reset itself, so resetting the circuit breaker alone may not do the trick. 

Because of the improved efficiency, ACs with higher SEER ratings tend to cool down your home better than models with a lower SEER. Higher-SEER AC units have a higher cooling capacity and a lower energy demand, meaning they may help cool your space faster without running up the electricity bill.
