Heritage Home Service is proud to serve residents from Massachusetts. We are the area’s premier home services provider and for 35+ years, we’ve brought the Heritage touch to homes throughout the state.
"I was told that the fee to simply come into my house to assess my furnace (that was not working) would be $260 on a Wednesday afternoon... and I was told this fee would not be absorbed into the work if I chose to have it done. If this company charges such an exorbitant assessment fee, I could only believe they would inflate other fees as well. I hired another local company for half that fee to assess then repair my furnace. Shame on Heritage Home Service."

When it comes to great service for your home or business, it doesn't get better than the professionalism and dedication of Rodenhiser. It's an unsurpassed level of service built on a promise that ensures you get the very best - when you call Rodenhiser your satisfaction is guaranteed. With 90+ years of delighted residential and commercial clients, you can be sure that it's a promise that Rodenhiser delivers on every day.
"One of the worst HVAC companies out there. 1) They moved to comission basis so their techs are trying to maximixe the amount you have to spend for each service. The more they do the more they get paid. 2) They are the most expensive service companies out there. 3) There techs are hit or miss. Some or good some are bad. 4) When they did a A/C service for us they missed changing the a/c air filter which caused a motor to burn out and a lot of smoke. Enough we had to call the fire department 5) They charged $931 to replace an electical valve that cost no more than $200 part and one hour to install. 6) Several times after they installed a new tankless system for us they had to come back to fix becouse they installed it wrong. It took weeks to get it running right. They have since charged about 4 thousandto keep it running over 6 years. 7) I have had them come out to service our working heater in the middle of winter to leave us with no heat for three days. We have been more than patient with them. Using them for some 5 years. Been hard to find someone good but we have finally done that and I am so happy we did. We have found a really good HVAC company that cost literally 1/2 what Rodenhieser costs for the exact same thing, without all the price gouging and unpersonal service. For instance to replace a ignitor costs $550 with Rodenhiser and $245 with a smaller local company. I am so glad that we can finally say goodbye to Rodenhieser. Do yourself a favor dont ever call them."

At WIRED Electrical Contractors, we’re pursuing excellence: from your initial consultation to our superior warranties and follow-through. Owned and operated by master electrician Paul Crowley, our team of trained and certified master electricians provide MetroWest MA homeowners with quality craftsmanship, upfront pricing, and attentive responsiveness throughout every project phase. Our focus on quality has earned us the Angi Super Service Award for ten years running. We are a full service residential electrical contractor. We specialize in home EV charging installations and are Tesla trained and certified. We are also certified installers with Qmerit, Chargepoint, and ClipperCreek.
"Paul was on time and got to work right away. He was very respectful of my home and put on boot covers as soon as he entered and placed a plastic protecter on the floor beneath where the fan was to be installed. Very neat and clean. While performing the installation, he informed me that the mounting bracket that was used for the original fan was only rated for a light fixture and showed me the difference between the screws used for the current bracket and the proper one. He quoted a price for the proper bracket and I gladly obliged. He also installed a new wall switch that controls both the fan and light kit wirelessly. The final results are perfect. Before he left, I asked him about replacing my noisy bathroom fan with something quiet and with a heater. Since a new line to a circuit breaker would have to be dropped, he checked out my electrical panel. He informed me that my current electrical panel was not up to code and who ever worked on the panel to add new breakers overloaded the panel (22 breakers in a 20 breaker panel). He was not pushy at all in having the panel upgraded to the proper size but did inform me of potential issues I could have in the future and that it is not up to code. I am extremely satisfied with the job Paul did and I plan on having Paul perform the other needed services I require. A+."

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."
