John and Johnny were great people to have working on my Hvac system. They put a bandaid on the system a few months ago and were upfront with us in what to expect in the next few months. They just finished installing a complete heating and air conditioning system and the work is super clean and left the outside and inside cleaner than they found it. Everything they installed was gone over with my wife and I so there were no questions about how anything works. Everything and I mean everything from the inside and outside unit,thermostat and drain pump was included in the ridiculously low price. I will recommend this business to anyone!! Thank you John and Johnny for a smooth and painless transaction!!

Our 12+ year old AC just wasn't keeping it cool upstairs. We wanted to hire a local, family owned, tax paying, licensed, insured company. That eliminated a LOT of companies. In the four years we've lived here we've had 6 different AC companies that didn't have a clue, did shady work, left without finishing or replaced expensive parts that weren't the problem.
Neighbors and a builder recommended Chamberlain Services.
They came by the same day.
We ended up choosing a new system instead of limping along. They didn't try to sell me a more expensive unit than we needed. They responded to every call and explained everything in terms I could understand.
Yes, you can find someone to do it cheaper but not better. Ask about their guarantee.

Professional and clear attention to detail, John and his team provided a tremendous service prior to this winter - all during this covid-19 pandemic. They showed up promptly, provided a comprehensive assessment of my HVAC needs, and provided a very competitive bid. After accepting the proposal the kept me informed before, during, and even followed up to ensure the work met my expectations. Its worth noting that I had 3 different issues that needed resolution and John was able to skillfully solve all 3 - much appreciated. Bottom-line, they understood my needs, charged me a fair price, and provided a high quality of service. I would definitely recommend Chamberlain's service.

My fabulous landlord found Chamberlain. They came out, did an estimate, were super friendly and ultimately won the bid to replace the ac. Two days later (I mean the ENTIRE thing had to be replaced), they were out here for hours, working hard, replacing the ac. I have no clue what the cost is but whatever it is was worth it. We have a brand new unit and John and his tech were very, very friendly, kind hearted, knowledgable people!! Thank you to my landlord and thank you Chamberlain!!!!

Chamberlain Services installed a Geothermal Heat Pump for me. They did an outstanding job. The installation was very clean and clearly very professionally done. They arrived exactly when they said they would, and got the work done very quickly. Their pricing was also very good, and I felt like I received a very good value. John and his son John also had a very good sense of humor - very fun to work with. Will definitely be calling again next time I need HVAC or plumbing work done.

Chamberlain fixed my AC unit about 4-5 years ago. My unit is the original and is over 25 years old.

It brokedown again the other day and the owner John came out the same day to take a look at it. The system needed a few new parts and he gave me a quote of $650-$900, depending on part cost.

When the job was done he was at the lower end of the price range rather than the high end as I tend to see from other service companies. Highly recommended.

We found out about John Chamberlin and his son from one of our clients at our business. Our home was in desperate need of a new water heater and have many years of bad luck with AC companies who had never fixed our AC correctly.

Let me simply say that when the owner of a company comes to your home personally and has over 30 yrs experience in the field, you get things done right!
couldn't be more happy with our experience. Highly recommend.

Six months later, during a hot week in June, our AC broke down, like it does every summer. It's 35 years old, so we've been preparing to replace it. Decided to go with Chamberlain Services. Very pleased that their final price was, to the dollar, the same as their estimate. Friendly and professional service throughout.

We had them install a new unit at our house this week. The price was good, the services was quick and best of all they were wonderful to deal with face to face! I highly recommend them!
