Nicholas Heating & Cooling

We had a great experience with Nicholas Heating & Cooling! When our hot water heater needed to be replaced last August, they responded very quickly and completed the installation fast and efficiently. The price was extremely reasonable, and they even removed and disposed of the old hot water heater for us, which made things so much easier for us. Highly recommend for reliable HVAC service!

I highly recommend Nicholas Heating and Cooling. I recently completed an oil-to-gas conversion, and while the process with National Grid was lengthy and occasionally confusing, their team provided guidance and support every step of the way. The installation was handled professionally—they arrived on time, worked efficiently, and completed the job promptly. When an issue arose afterward, they responded the same day and resolved it quickly. Their responsiveness and professionalism made what could have been a very stressful experience much easier to manage.

We are an industrial customer and have been doing business with Nicholas Heating and Cooling for over 20 years. They have installed and continue to service all of our HVAC as well as process boilers and consistently deliver the highest level of quality and professionalism. Pricing on new installations is always highly competitive, and the workmanship is excellent. Reliable, knowledgeable, and straightforward, Tom has been a long-term partner we trust and will do business with for years to come.

Nicholas Heating and Cooling is the real deal. On time, knowledgeable, fair pricing, and quality work. They explained the problem clearly, fixed it right the first time, and left the space cleaner than they found it. It’s hard to find contractors you can truly trust—this is one of them. Highly recommended.

Lost heat on holiday and thought I was going to have to wait a couple days. Called every number in the book. He was the only person that picked up phone and he showed up within couple hours on holiday weekend and got me up and running. Was good rate, fast, dependable company ID say ... that answers there phone and returns calls!
