CARJON Air Conditioning & Heating, Inc.
Had our yearly maintenance on our furnace. Tyler B. did a terrific job today. Helped us identify a problem with our furnace starting/stopping too frequently, and pointed us to a new thermostat we adjusted to make it less frequent. He was polite, informative, and did a great job checking out our two furnaces. Thanks Car-Jon for sending Tyler today.
Joseph B. was right on time, very professional, and performed the work with great skill. Answered all my questions and explained in knowledgeable detail what he found and the condition of the furnace was before and after the tune-up! I have been with CarJon for 4 or 5years now and very pleased with all there burner services provided to me over the years. Yes i recommend them!!
Just had CARJON service my furnace at my new residence. I received a text saying they could move up my appointment by 5 days which I gladly accepted. Dan M and his colleague arrived within the timeframe mentioned and completed the required maintenance. They were both very polite and respectful as well as explained all the work performed in language I could understand. Very happy I chose CARJON and signed up for a preventative maintenance agreement.
Jan2026 Update- I am still a Prestige Customer, there's a reason for this...they are the best. I just had my 20 year old Furnace and Central Air unit replaced by CarJon. Robert Lanni was my contact/estimator and he was a pleasure to do business with. The estimate was very thorough and efficient since Rob completely reassessed our square footage because we have renovated since original system install. Install was clean, quick and efficient as well. The installers could not have impressed more. CarJon has been an outstanding vendor throughout the years, I endorse them highly.
Had issues with existing heat pump not keeping up in cold weather. Called a couple other companies to look at system & was told everything was fine . Robert from Carjon came out & immediately pointed out ductwork issues & issues with lack of return vents. Knowledge of these systems was immediately evident. Recommended a Mitsubishi hyper heat system & the difference was amazing. House maintains perfect temperature even on nights when temperatures drop to near zero. Get it right the first time and go with Carjon.
5 stars and if more were offered I’d go for all of them. When the furnace stops working and the temperatures outside range from minus 0 to single digits — all while you’re out of town, it’s stressful. The thermostat read 45o when I walked in, so the house was uninhabitable. Carjon got someone to the house super quickly and within a few hours we had a diagnosis of our 10-year old, ice-fried furnace, a recommendation and an estimate. I can’t say enough good things about Elijah, Jared and Kevin, the crew who came to remove the old furnace and install new. They arrived with nothing but professionalism and a positive attitude and left the same way, after working 8 hours in a freezing cold attic. With no breaks. Before they rolled out, they made sure to leave the house as clean as they’d found it — maybe cleaner ; ) In addition, Elijah patiently went over everything, including how to operate the new thermostat and helped with setup for remote access. I highly recommend Carjon if you value prompt, efficient, professional service.
