"The technician at Ridgeback was able to fix a mini-split we had installed by another company 3 years ago. The company that installed it refused to fix it and offered to install another unit if we paid for it. They were terrible to deal with so it was a pleasure to find a company that was dependable and good at getting the job done. I would highly recommend Ridgeback to anyone!"

"These guys rocked, from the time I called on a Friday, to the install of our brand new furnace the following Tuesday! Technician-Scott and Ryan were prompt, friendly, informative and professional. The quote/estimate given was fair/reasonable and in the end was what we paid. Installers-Oscar and Kevin were prompt, friendly, informative, professional, quick and did an outstanding job. Thank you to everyone at Elevated Comfort for your great service! I would definitely recommend them to anyone needing HVAC work to be done!"

"This is a family owned small business. They are friendly, professional, punctual, and really know their stuff. All at a very fair price. My AC had been getting worse every year until last year. HVAC Utor came out and fixed it. It ran better than ever before. This year it was just blowing air so I called again. Same great service as last year. Rachel kept me informed so I knew when they would be here. The problem turned out to be the new thermostat I had installed a couple of months ago. Diego had it figured out and fixed in 15 minutes. I can't say enough good about this company and the people who run it. They're the best!"

"The team of four was very professional and performed an excellent job in a record period of time. Just one day to take the old furnace away, replace all the old boots and duct work and install the new furnace. They paid a lot of attention not to damage or dirty the floor/carpet. I am very happy with their performance. They may not be the cheapest on the block but it was all worthed and you only have to do that once in your lifetime."
