"Charged $2,000 (that's right, $2,000!) to install a new sprayer faucet and soap dispenser in Boston. $1,500 went to labor, which took less than 2 hours. I'm sorry, but $750/hr is outrageous. I did pay it because I wanted to expedite solving the problem for the tenants, but I now regret as their dishwasher is not working and I suspect the plumber failed to reconnect everything probably."

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."

"We had an issue with a Dry Well periodically backing up. Damian and the D Day Plumbing team were very professional and knowledgeable and provided an estimate with a couple different options and their related costs. They installed a new utility sink, sink pump, and needed piping and valves with tie ins to the main septic. They made improvement above and beyond the initial job breakdown, all the while staying within budget. I will certainly consider them again for any future work. Thank you Damian and the D Day Plumbing Team for a job very done!"

Hvac Repairs questions, answered by experts

If your furnace breaks then you’ll first need to check your thermostat settings and make sure they’re properly set and working. You should also double-check if you’ve accidentally tripped the breaker or blown a fuse. It’s best to call a professional for repairs, and you may want to turn your faucets onto a slow drip while you’re waiting, depending on how cold the outside temperature is.

While you can run your HVAC system without an air filter, it isn’t something professionals recommend—especially not for an extended period. It can reduce indoor air quality, clog air ducts, and strain your system. This can lead to performance issues, higher energy bills, costly repairs, and a reduction in the system's lifespan.

Air trapped in a heating system can lead to reduced efficiency, uneven heating, increased wear on components, strange noises, and even complete system failure. This trapped air disrupts proper circulation, strains parts, and can cause overheating. Regularly bleeding baseboard heaters and furnaces can prevent these issues, ensuring efficient operation, even heating, and prolonged equipment life.

Yes, many services include reinstallation or securing the unit after servicing. Confirm with your provider.

Whether the furnace will work with a dirty filter depends on just how dirty it is. The furnace will continue to work for a while until the filter is so clogged that air can’t pass through. The dirtier the filter gets, the less efficient your furnace will be. Replace your filters regularly so your furnace won’t completely quit working.
