Carroll Heating & Cooling

John installed a new central air system for our home. He is very responsive, professional and offers a fair price. We highly recommend John and will call him for future air and heating needs for our home.

John did a great job of investigating our issue with our boiler system, coming up with a solution and resolving the problem. He did the work quickly and effectively - and at a very fair price. I would recommend John to anyone with heating and/or cooling needs.

John was absolutely my hero last winter!! My furnace died in one of the coldest weeks of the fall. John was mobilized and had my furnace running for an incredibly reasonable rate within 24 hours so I could be warm. He then returned and detangled my super inefficient ductwork so my heating bills have dropped!! I never felt that he was trying to sell me anything I didn’t need and have been tremendously pleased with the performance of my new heating system over the past year and a half. He was always super personable, responsive, professional and put up with allllll my stupid questions. I couldn’t recommend he and his business highly enough!

I have used Carroll Heating and Cooling several times. From a new furnace at one house to a new water heater and ductwork work for new addition at another house. John easily located the source of a gas smell I had in my house for years. The leaky pipe joint was quickly replaced. Always professional and on-time. Pricing was extremely Fair and John will always be my first call for my heating and cooling, Etc needs.

John was punctual, competent, efficient, and fair with the cost, to bring my Crown boiler quickly back into service. He willingly shared his in-depth knowledge of this heating system and more reliable, simpler zone valves.
Highly recommended.

We've used John Carroll for for annual maintenance at my daughter's house but recently used him to replace HVAC at house we downsized to. He replaced furnace and AC, as well as replacing an 80 gallon water tanks with a tankless water heater. We are very pleased with the results. John was very fairly priced, patiently answered my many questions, and he and his crew worked very conscientiously without making a ruckus. I couldn't believe how many ducts and tools and pieces were needed in the work site in our basement but when they finished everything was completely picked up and neat. Carrying out the old 80 gallon tank was a task in itself but they maneuvered up a narrow staircase with no damage. He did safety check on gas lines and at my request removed some that were no longer needed, as well as adding a furnace duct and a return in a finished portion of the basement that will. I researched the Rheem AC and furnace and the Navien tankless water heater, and all top of the line at a great price. The installations are beautiful. I would highly recommend John.

5 star service for sure. John installed a 4 ton ac unit for me at a very good price. John was also extremely honest and professional. I also own rental units, and know how hard it is to find someone reliable. John is the guy!

Fantastic experience!

I highly recommend John and Carroll Heating & Cooling! Always on time, stands by work and always professional. As a Realtor I’ve referred and used him many times, and have always received great feedback! Add to that super competitive pricing! Give them a try, you won’t be disappointed!

John did a great job! He was able to meet my tight timeline and made sure the job was totally complete and cleaned up before he left. I would definitely recommend him!
