CARJON Air Conditioning & Heating, Inc.
I could hardly be more disappointed in Carjon. I need a new thermostat for our house, which has two systems—one of which has stopped working. We swapped the thermostats between the units, and the issue clearly follows the thermostat. I called Carjon to order a replacement, but the best they could offer was to schedule a diagnostic visit a week away. They couldn’t even confirm if they’d bring a new thermostat that day, suggesting it might be a fuse or breaker issue instead. What a frustrating experience. Carjon installed both systems 5 years ago. UPDATE: 10/06/2025 : I ordered a thermostat, it arrived promptly, and I installed it myself without any issue. The process was simple and straightforward. It is disappointing that Carjon did not seem interested in assisting with such a basic request or in listening to a customer’s needs. I understand that businesses have procedures in place, but when those procedures hinder rather than help customers, it may be time to reevaluate them. Regarding Carjon’s response below, to clarify: I was not requesting a repair quote — I was simply asking for the price of a thermostat. Instead, I was told I would need to schedule a technician visit, pay the standard service fee, have the technician confirm that the thermostat was faulty, and then be informed of the replacement cost — all with a 10-day wait. This approach is unnecessarily cumbersome and does not serve the customer well. I would strongly encourage Carjon to review this process and consider a more customer-friendly approach moving forward.
Learned that heat pumps/AC last 15 years. Ours died - freon leak at air handler. Did not want to repair..... Researched replacements (Trane or Mitsubishi). Got several quotes. Carjon was higher than hoped for, but spec'd for total system replacement since ours was a 35 year old hodge podge. Others would use existing (crummy) ductwork, saving 40% while also skimping on needed electrical upgrades. Carjon was the only company to do Manual J calc. If you don't know what that is, ask. If dealer won't provide it, RUN! Took 3 days, avg crew of 3, and results are fantastic. If you want things done right, it's $ well spent. PS: did homework and called Trane directly. Carjon is the top dealer installer they recommend in my area
We recently had our AC system checked out by CARJON as part of our annual maintenance program. I believe the tech’s name was Ben and he did an excellent job. He came prepared, he was neat, professional and courteous and he gave me a comprehensive report upon finishing. Good job, Ben and thanks, CARJON!!
