  Jim and Chris were great to work with. Super knowledgeable and efficient. They replaced my furnace and outdoor unit and were very professional. Brittany was always pleasant to speak with on the phone when we discussed anything, and she also was super helpful in guiding us toward fantastic financing options for the work and equipment. I would absolutely recommend and use Guaranteed Comfort again. The only knock I would have, and it would be a 1/2 star knock if we could, is the proactiveness of communication. There was a follow-up action that needed to be completed after the initial install and I had to make the call to them to schedule the follow-up instead of them contacting me to schedule. In the grand scheme of things, it's insignificant, but it is one thing keeping this great company from being stellar.

  We have a 1.5 story with knee wall attics and it is much more comfortable now after having it air sealed and insulated. The upper floor is not hot anymore and we've needed to set the thermostat at a warmer temp or it gets too cool. That's a nice problem to have when you couldn't get it cool enough before. The basement isn't really cold anymore and there aren't the hot/cold spots in different rooms that we used to have. The team was great. Jim inspected the house and came up with the plan and Chris put the plan in place. The guys were there every day for some long hot days and always checked in morning and evening to let me know where things were at. Their attention to detail was impressive and they also cleaned up inside and out (no messes). Reliable and nice guys (that's hard when you've been in a 150 degree attic for days). We are very happy with Guaranteed Comfort. Thank you!

  My husband and I are so pleased with the great service we received from Jim, the owner of Guaranteed Comfort and his employees. With colder weather approaching, we were grateful that Jim found the issues with our furnace and was quick to fix them and also put us in touch with someone able to help us with financing as we needed to replace the whole system. Jim was also able to give us some tips to make our home more energy efficient, that we were able to do ourselves. I would highly recommend Guaranteed Comfort to my friends and family!
