“Ray is honest, fairly priced and easy to work with . He did a great job replacing incandescent lights with recessed led lights. We will have him back for future electrical needs.“

“The two gentlemen were very skilled and knowledgeable, friendly, and wonderful to work with. I would use them again! They didnt mess up our white carpets coming in…which we appreciated…and though it was a very messy job, they cleaned up afterwards….they did an excellent diagnostic, test and thorough cleaning of our very old refrigerator!!! And they took the time to answer many of our questions! Im looking forward to many more years of our Kitchenaid refrigerator.“

“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.“

“I had my HVAC replaced 4 years ago, with a tankless water heater! They were very efficient in the installation! I purchase the contract every year! It has been a pleasure working with this company! Great customer service!!“

“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!“

“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.“

“1st time use for cleaning furnace. From booking to Elijah the tech was very smooth. No thoughts to try any other company now! Just keep us warm Big Al’s?“

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!“

He checked all the hoses and cleaned the furnace.“

“We had a huge problem with the flashing system in our toilet and we were desperately looking for help. Unfortunately for us, other companies that we contacted ether did not do residential plumbing in our area or can't promise anything in about a week. Super Service Today company was very responsive and they send us the service man right away. Roy C did a wonderful job for us. He came to our house just after 10 am and at approximately 12:30 pm a brand new toilet was installed. First he analysed the situation and explained everything for us, then he calculated 3 different options to fix the issue and gave us enough information to make our own decision. After we did it he immediately started working. The result is very impressive to our full satisfaction. Good professional job! Thanks!“

“I woke up to no hot water a few days ago. Excel Mechanical was quick to send Ivan out the next day and tell me what I already knew inside... it was time for a new tank. I picked out a Rheem tankless gas heater at Home Depot then Ivan got to work installing it the next day. He did a great job, beautifully installed!“

“Gas stove starter died and Merrimac Plumbing came the same stay and fixed it.. Great service“

“Dylan is the best! Very professional, friendly, explains everything even if you ask several times. He is very patient and thorough. Dylan came to help with our air conditioning/air quality system and spent a lot of time making sure to my satisfaction ( I am the one with the sensitive nose) that the air smelled clean.
Dylan was so kind to give my dog Butter lots of pets (Butter if he could write a review would say Dylan is a great guy who gives the best belly rubs and is so greatful that with all his flying fur that he will make the air cleaner and non allergenic.“

“A year ago, my ductless minisplit heatpump system was leaking refrigerant and I couldn't get any HVAC company to properly diagnose the leak... until I found Unique Indoor Comfort. Within 30 minutes of arrival, Chet, one of their top technicians found the leak. I worked with Tom and George, and they had a repair plan in place and in just a few days, my system was repaired and working properly again. No more refrigerant leaks. -- Fast forward to this past week, I needed a new furnace for my house. Again, I worked with Tom and George and spec'd out a new system to exactly meet my needs and priorities. Adis, Curtis, and Bruce showed up and did a fantastic job getting the new system in quickly and cleanly. The things I liked the most about Unique Indoor Comfort are their attention to detail, their solid work, and their excellent communication skills. Everyone in this team listened to me, were very friendly, and made sure my questions/concerns were answered and properly addressed. Top tier service.“

“Well done! Efficient, quick and very professional. Can't ask for anything more.“

“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.“

“Furnace and A/C compressor were professionally serviced. There is one pending compressor issue to be resolved by next spring and possibly another issue with the furnace (TBD this winter). Outstanding service.“

“Great work fast and efficient. Employees are very nice and respectful. Best company I have worked with.“
