Heating & Air Conditioning / HVAC near Middleton

“Absolute installed a new Burnham Alpine HE gas furnace and indirect water heater a few months ago. Great job by the team in the work they did and the products they recommended. The site was left very clean and the system is working fantastic. Highly recommended and deeply experienced professionals.

Update: another great visit by Absolute. They came by to address some other plumbing issues we had. Quick communication, professional staff. The work came out great!“

“Boiler broke on very cold and windy day. Called Mark and explained the problem. He showed up the next day with the right part and fixed us up by lunchtime. Shared some useful boiler knowledge then cleaned up bid us farewell. The house was soon nice and toasty. Great service. Great person to do business with.“

“Professional, punctual, fairly price, and great at what they do. I have nothing but good things to say about Mr. Wright and his work!“

“John came to troubleshoot an issue I had with air in the water lines.
Was quick and clean. Able to solve the issue and explained it clearly.“

“Quickly evaluated and fixed the problem with my mini-split AC. They are prompt in keeping appointments, as well. I highly recommend Burke and Sons in Haverhill for anyone with Heating or AC problems.“

“Chris from CMS came and found the broken pipe. He gave me an estimate, which was reasonable and completed the work all in a couple of hours with minimal mess in the house. He was professional and I appreciated that he explained the problem and the repair, and took the time to answer my questions. Great experience, thank you!“

“Anton and his team are fantastic. They installed my ductless unit back in 2022 and it’s been a game-changer—efficient, quiet, and reliable. Recently Anton took my panicked call about water in the basement from my central AC, came quickly, diagnosed the issue, and fixed the leak. He explained everything clearly, made the process easy, and is also just an interesting person to talk to. Knowledgeable, professional, and highly recommended!“

“Chiming in as female homeowner in Millis, MA who is not familiar with heating systems: “working with Commtank was an Outstanding experience! Dave the Surveyor was immediately available and super helpful. He took the time to explain the oil furnace system, tiger loop, and different tank options. He gave me a quote during his visit so I didn’t have to wait. The women at the office were able to schedule me within a week so I had no worries on waiting. The crew showed up and got the job done within 3 hours. They had the fire department come over to double check and sign off before they left. Everything is spotless. And the price of $4555 for a Roth 275 gallon tank w 30 year insurance was unbeatable. I love this company and everyone who works there. Absolutely recommend for anyone who needs to replace an oil tank. Mine was ~70 years old“

“Joseph came to assess our HVAC system after we used MULTIPLE other companies that could not identify or address the issue we were experiencing. He knew what the issue was immediately and was so knowledgeable, personable, and kind. Highly recommend!!!We also worked with Dan, the owner, who was amazing as well. We will only be using this company moving forward for any HVAC needs!!!“

“Monkey Wrench (Eric) is on time, responsive, skilled, knowledgable and fair and transparent with his pricing!!! He moved seamlessly between a few smaller issues and solved the biggest one!!! I also requested and received a quote the same day on another job I need done!!! I would highly recommend him for all your plumbing/heating needs, big or small!!! Thanks, Eric!!!“

“Brian was the technician that came to do my winter tuneup. He was very helpful and very patient with me because I asked him a lot of questions and he took the time to explain things to me. Your company is very lucky to have such an excellent technician. I'm so glad I have a contract with Central Heating And Cooling.“

“Raffie was pleasant and efficient in identifying the reason our a/c stopped working, a plugged up drain. He came early afternoon to respond to our call to Sila after hours just last night, so Sila gets credit for that. The work was within warranty so cost us nothing. Thank you Raffie and thank you Sila!“

“This review is for an annual maintenance done in September 2025 for mini splits by Daniel Ruiz. He arrived on time, neat and very thorough. Made sure to wear booties inside the house and communicated well with us. He made sure everything was working perfectly and draining properly through our gutters. The one year old compressor had some insulation already splitting so he taped and secured it with some zip ties and took photos of the 12 year old compressors’ insulation that is disintegrating to get a quote to replace. Awaiting company to respond. Daniel is very experienced and highly recommend him.“

“They installed a natural gas heating system for us in July. Very impressed with the quality of the work and professionalism. They are extremely organized and everything is installed with clear labels so it is understandable for anyone.“

Our AC UNIT. I learned a lot! Great service!“

He checked all the hoses and cleaned the furnace.“

“I don’t often write online reviews, but this experience truly warrants recognition. Shawn recently replaced our water heater, and I couldn’t be more impressed with the quality of his work. The installation was completed efficiently, with great attention to detail, and at a very competitive price.

It’s clear that Shawn is in high demand—and for good reason. I feel fortunate to have secured his services, and I wouldn’t hesitate to recommend him to anyone seeking reliable and professional plumbing work.“

“Our project was extensive, involving changing over from boiler, radiant heating, and multiple air conditioning units to a four heat-pump based system. We interviewed five different companies, and chose Lohrman due to an overall gestalt of competency, competitive pricing, and prior customer feedback.

Lohrman HVAC truly exceeded expectations and here is why:
1) Service: Today we needed a service call, which we placed at 7am, and at 8am a representative was at our door. The problem was fixed an hour later and they are coming back this afternoon to do additional work to make sure the problem doesn't recur.
2) Efficiency: They made a plan, executed it, all within the time frame delineated. Awesome!
3) Dependability: They arrived on time each day, cleaned up and left on time, leaving us with a chance to live normally with workmen in the house.
4) System design: Properly analyzed our requirements and did not under or over-size the equipment.
5) No surprises: Did not have hidden extra costs during installation.
6) Worth the money: We discussed whether we should go with a less expensive company, but given the above reasons, we were more than happy to pay a bit extra for superior service.“
