Tyler arrived promptly and resolved the issue, which seemed to be a consequence of an error made during the system's installation last August. The problem emerged just before the warranty for the installation was set to expire, which was fortunate.

CarJon went above and beyond for me yesterday when a routine furnace check up lead to the discovery of a gas leak. It actually was leak from a pipe that was 3 floors above us but converged in our condo. They called RIEnergy with me and explained to the emergency technician what was wrong. The supervisor and their gas specialist all stayed and kept us safe while assisting the gas tech, the condo board, the management company and lastly a plumbing company. Before they left they made sure I understood what was happening and what the others were doing. I cant thank you enough for all you did yesterday and not deserting me!

Jeannie was wonderful and cooperative in making an appointment, reconfirming a few days before and calling when the technician was on his way. Kyle arrived, wore his mask as requested and went straight to work, answered all my questions with non-technical jargon, cleaned up after himself, reminded us to change the return vents (and to reset the thermostat to heat!) and was on his way. Kudos to everyone at Carjon for keeping us warm in winter and cool in summer for over 25 years.

In a time when professionalism and quality are often lacking -- it is a joy to work with CarJon! I have had A/C service with them for many years, and can not say enough about them. From the office staff to the workers that come into the home - I have NEVER had an issue. They go above and beyond to be helpful, answer questions, and give explanations on the systems that I know so little about. If you are looking for superb A/C or Heating company -- CarJon is your man!

Jason V. came out recently with a colleague to tune up our AC system. He was able to diagnose a problem we were having with mold forming on ceiling around AC vents, which turned out to result not from the AC system itself, but rather from excess humidity in our home in the summer months. We were impressed both with Jason's expertise as well as his eagerness to address our concerns. He laid out steps that we should take if the problem recurs this summer, and provided a very thorough write-up of his analysis. First-rate service.

My furnace died on sunday morning and we had a carjon svc rep assess the situation sun morning with pictures. This led to discussions w service team and replacements parts were found locally and repair appt was made. However that morning we had the horrible news from our vet that we had to euthanize our 12 year old dog - the Carjon folks re-arranged our svc appt and we had our furnace back running by the end of that day. Outside temps had dropped to below freezing so we were very appreciative of the Carjon team. Thank you guys and gals and you can be sure we will continue our relationship ongoing.

Horrible company. I waited three hours and they didn't show. I called and they said I cancelled. I did not cancel. I took the day off just to be here and I run my own business. I get that mistakes happen. However the woman said they would never have done that. Zero accountability. And their answer? I can get next available.another month out. Tired of these big companies. Stay with locals. These other companies simply don't care about losing customers.

A Carjon technician was here for our annual spring air conditioning service and, again, we have nothing but praise for the company. Knowing how busy they get, we made our appointment months early and several days ahead they called us to reconfirm, checking to be sure no one in our house was ill and reminding us to wear masks. On the appointment day, they called to let us know Steven was on the way, and he arrived minutes later. Patiently, courteously and efficiently, wearing a mask, Steven went about his work, asked some questions, asked if we had any, cleaned up and was on his way in next to no time. Friendly, helpful, efficient - you cannot ask for more, but if you did we are sure Carjon would go out of their way to provide it.

Avoid this company! They installed new central AC to my house and they didn't seal the whole where they installed the ac line. Very cheap work and unprofessional crew put my family in danger because their irresponsibility. Two months after they left we found a mouse in the house living with my 2 babies. We hired a professional company to take care of this matter and they found that Carjon crew didn't do the correct job leaving holes unsealed.
They sealed and corrected all Carjon mistakes and resolved my issue. When we contacted Carjon they were rude and tried to tell us that the company we hired lied to us. Stay away from unprofessional people who charge a lot to install an AC because your gonna end up paying thousands for a pest control company.

CARJON does not disappoint! Since purchasing my home in 2015, I called CARJON to use their yearly maintenance services. They always remind you of your yearly inspection, provide excellent customer service and show up on time! I called for an inspection and found some issues with my heating wiring. Justin was EXTREMELY knowledgeable and performed the job today with high professionalism and care. The cost of the job was very fair and well below the competing rates.

CARJON Installed my air conditioning system 12 years ago. Their work was performed timely and neatly. They were very professional and courteous. They have maintained my system with a reasonably priced service plan that provides for them to service and check the system in the spring before the air conditioning system is needed. The annual service maintenance has always been done timely, professionally and as scheduled. I have not had any service problems while under their annual maintenance service plan. Thank you CARJON!

I used Carjon in 2018 to install a mini-split, and was very happy with their initial service. They were responsive and prompt, and I was quite happy with the work done during a busy time of year. Since I have had the initial installation, I have found it much harder to coordinate maintenance. Originally, I was contacted by Carjon to go over potential service options. However, after I replied I did not hear back, and another follow-up email didn't result in a response either.
I wind up thinking that it's not a big problem in the scheme of things, and would use them again if I needed something installed, but it was somewhat disappointing. Overall, their work was good quality and they were helpful in my decision making process.

Waited weeks for a salesman to come out for a quote on central ac for my home. Requested a quote for a ducted United and the Mitsubishi ductless. Then weeks go by and no quote so I call to follow up. Finally got the quote with some computer error excuse but there were two quotes for ducted systems. I called back and left another message requesting the ductless quote we talked about still waiting for for this elusive quote.
The sals rep was a my house the end of September. I guess they don't need the business. I have moved on to other Mitsubishi diamond dealers who have had no issues getting me a quote on the spot or within 24 hours.

Recently had my boiler system replaced with a high efficiency model; it was a big job, requiring all new piping, and existing lines to be moved. Carjon did an excellent job, and made sure everything was done correctly, neatly, and efficiently. The were very professional and friendly, and made sure to answer any questions or concerns I may have had. When they began work, they made sure to lay down tarps to keep the floor from getting dirty or damaged, and made sure to vaccume and clean up when all work was done.
They even provided me with space heaters for the couple days where the heat would not be functional while the work was completed. The crew was a pleasure to work with, the equipment is working great!

Thanks for wasting our time and money carjon. We recently moved into a new home that has a newer HVAC system. We are uncertain about a few things with how our system is running. We asked carjon to come out to give us a list and quote to help troubleshoot some issues. (Obviously it coasts money for them to come out to take a look)The technician told my husband to rip out this relatively new system and for them put in a brand new one. I'm sorry, the system is NEW. why don't your technicians learn how to trouble shoot through the issues! Instead they are trying to make a quick buck. not impressed. very unsatisfied customer

In Dec'16 Carjon installed central air on time, on budget. Very courteous, efficient and knowledgeable crew : 5 stars. So when I had a heating issue with my gas boiler in 3/17, they were the first company I called. Experience was 1 star at best. First, I told them the boiler was messaging a faulty stack sensor and just assumed they would bring the part. They didn't and need to return ($).
They costed the part and replacement at $425. They refused to break down part and labor insisting it's a fixed price. After a few calls I purchased the part locally for $38 and then called another licensed service company to install - it literally took the technician 30 seconds. ( The sensor is readily accessible on the outside and no need to even open the cabinet ( no tool needed). I then used the technician's time to clean the heat exchanger and due a tune up which Carjon said needed to be done which they priced at $560.
It would have cost almost $1000 to use Carjon - I ended up paying about $275. //. My experience - it was like dealing with two different companies. Great A/C installation - heating service not so much.

We used Carjon Heating and Cooling (Cumberland, RI) to fix a gas furnace in February, 2014. A previous contractor had told us that many expensive parts would have to be replaced and we might as well buy a new furnace. The Carjon technician spent a lot of time troubleshooting in a cold attic and found that the problem was a high temperature limit switch that had shorted out. Kudos to that technician. Prompt, courteous and knowledgeable.

I have to agree with the previous reviewer. Carjon was top notch. I had 4 other companies compe out to give quotes for a replacement heating/AC system. Carjon was the most thorough and professional they took the time to properly size the system and give options that would best fit our home. There quote, although no the cheapest was the most detailed. They answered all my follow-up questions very thoroughly.
After deciding to go with them they scheduled installation about a week later. The installation crew was very professional and the quality of their work showed. I am very satisfied with my new system, and was very impressed that Carjon followed up with the necessary rebate paperwork and made sure everything was to our satisfaction. They have defintely made me a loyal customer and would defintely recommend them to others.

Had a central AC system installed on the 2nd level and a ductless system installed on the 1st level (open floor plan) in March 2016. Install was super clean in just one day. Technicians were very knowledgeable and friendly and willing to answer tons of questions. The AC worked extremely well throughout the summer as promised. The condensing units are right outside the window near where we sit to watch TV every night and you cannot hear them running at all, just as was explained to me by the salesperson, Rob, who was also excellent to deal with and made himself available by cell always. 1 year in and the equipment is still just as good as the day we got it. Extremely pleased with CARJON. Recommended them to two coworkers who were in need of AC this upcoming summer.
