These guys messed up the wiring when installing new heating system, now they don't respond or show up. Paid another company $250 to fix their mess. Update: Called them 3 times in one week on 3 different days and every time their customer service rep. said we will send the technician when they become available.

Simply put, THESE GUYS ROCK! Had a heck of a day with my son being born and our A/C going out the same day. They took the stress of the day off my plate and was able to come, quote, and install a new AC unit and furnace THE SAME DAY. Big shout out to Phil, who is a consummate and caring professional. You have earned my repeat business guaranteed!

Air conditioner on the fritz. Called at 8 a.m. and had a technician here at noon. John was very thorough and explained the problem, repaired the same and gave us tips of simple things to do on our own. Highly recommend this company and their staff! Thank you!

All around excellent service! From first contact through full install, it was only 1 month which was fantastic. Our rep, Mike, was so helpful in explaining the process and the products used. The install team was able to get our unit installed very quickly, and were very nice to work with.

These people are awesome! We've received HVAC services from D&J for 30 years and everyone - I mean everyone - at this company has provided us with excellent service. This past summer Steve helped us pick out the right heating and AC systems (it was time to replace them both). He was very professional and took the time we needed to answer all our questions. Max and Dave and Kevin installed our systems, treating our house as though it were theirs - careful as they brought in the equipment and cleaning up afterward like company was coming!
They spent time explaining the new thermostat so we can run our system like pro's. D&J also provides annual maintenance services for us and every one of those technicians performed to the D&J standard of excellence. We highly recommend Donovan & Jorgenson Heating & Cooling.
