We reached out to John on Friday when we realized our AC was no longer working. He said the earliest he could get there was Monday. Of course, this was going to be one of the hottest weekends too. Sunday morning, he shows up to our house, unannounced, and assesses our AC issue. An hour or so later, our AC is repaired and back up running. This is customer service unlike any other. We HIGHLY recommend John to anyone who requires HVAC service. He’s knowledgeable, professional, and provides high quality work. Thank you, again, John!!

John was excellent from beginning to end. John was quick to stop by and offer an estimate and was able to fit our project in (complete installation of furnace and AC) in less than 2 weeks. The project was done in less than 2 days, and the workspace was left cleaner than he found it. I cannot recommend John enough for any residential HVAC project you might have.

After several estimates, went with John Carroll due to his timely response, knowledge, professionalism, quality of equipment used, and competitive yet fair pricing. Installation was done on time and efficiently. Very happy with our decision and would highly recommend John.

John is an amazing professional. He came to our house on a Sunday and replaced a part of our AC. He was very friendly, informative, clean, conscientious and very very reasonable. We would recommend this business to anyone that is in need of heating and cooling!Thank you JohnDiane George

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.

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 has installed 3 furnaces and 1 central air unit for me. I have referred 2 of my uncles for new furnace installations, they were very happy.I personally have become friends with John and very fond of him as a person and professionalism. I had a problem last winter with my furnace and my homes temapture was dropping fast with the extreme cold we were having. With just 1 text John was right over to fix the problem.Great guy- great price 5 out of 5 in my book !

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.

Weve used John Carroll for for annual maintenance at my daughters 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 couldnt 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.

John is extremely knowledgeable and professional - we will continue to call him for all of our heating and cooling needs!

Needed to swap my furnace from oil to propane in December. Big job...and was started and finished that day. Excellent work! Very satisfied! Recomend to anyone looking for HVAC work.

I use John Carroll for snow plowing and my HVAC services. First: snow plowing. I’ve used three snowplowing services in Irondequoit before John, and he has been the only reliable one I’ve used! Second: HVAC...responsive, courteous, neat, and well priced.

I can trust John to do great work and be reliable and honest.

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!

Very professional! Great experience with Carroll Heating & Cooling! My go to HVAC guy!

John helped me out with a last minute water heater replacement. His fast service turned what would have been an emegency into an inconvenience. Now hes my go-to for any heating repairs and service.

Super fast, professional, and best price around!

John helped us out with a short notice service appointment that we needed for our house closing. Thanks!

Quick response time!

Honest, reliable and trustworthy.

Fantastic experience!
