After 25 years, my Concord home needed a full HVAC replacement. I did my homework -- four quotes,…read moreverified equipment certifications, asked hard questions about duct sealing, zoning, and equipment sizing before deciding. A-1 answered every question confidently, corrected a spec error in their own quote when I caught it, and put everything in writing before I signed. Install day: Austin, Joey, and Edgar showed up on time. Floors covered, shoes covered, house treated well. Two days -- day one removal and new equipment, day two ductwork and zoning. Heating and cooling tested before they left. Full documentation handed over on the spot. No hidden charges, no surprises, no change orders. Price was mid-range among four quotes, but the warranty structure -- lifetime workmanship, no-lemon guarantee, payment at completion -- made it the best overall package. Still have HERS test-out and city inspection scheduled, but based on every step of this process I'd recommend A-1 without hesitation. Austin, Joey, and Edgar did a great job.

They've proactively let me know if parts needed to be replaced. All the technicians, like Roy who was here yesterday for my regular maintenance visit, are incredibly competent, efficient and gracious. Thanks also to Jessica who helped me with scheduling.

I called Rich at Creative Comfort because my wall heater wasn't working. I had previously got a…read morequote from another company who told me the heater couldn't be fixed and they would replace it for close to $3000! It just didn't feel right. I suspected they were trying to take advantage of me. So, I called another HVAC company that had worked on my air conditioner and they referred me to Rich. I'm so glad they did! Rich showed up right on time and got right to work. He was able to fix my wall heater instead of suggesting an expensive replacement. And I'm happy to say that the heater is working perfectly now! Rich is one of the last honest technicians out there. I highly recommend creative comfort systems for all of your heating and air needs.

We have a building in Fairfield that needed a new a/c system…read more We used them as they were low bid. They put in a new system but did not replace the 20 year old out-dated thermostat or even look at it evidently. The system failed a couple months later. We looked at the thermostat first and discovered that the batteries were so corroded that we had to pry them out with a screw driver. We called Superior and they said the they did not replace the thermostat because the one they would replace it with would be inferior. Really? We replaced the fuses in the system and could not get it to run, so we called them out to check it out. They had replaced the thermostat with a new one and said that the fuses were blown out. That seems funny because I just put brand new ones in before they arrived. They sent us a bill for over $300.00, which is probably not that bad, but when I went to check the work, they left the whole side panel off of the unit exposing high voltage capacitors and wiring. The cover was about 50 ft. from the unit in the front of the building. They also left the circuit panel door open in their hurry to get out of there. When a company lies to me and does shoddy work, I do not ever use them again, nor recommend them to others.

If you ever need HVAC Services, Repairs, or Replacement, do yourself a Big Favor and call Brisk…read moreHeating and Air! Well worth your time and money to ask for their help and expertise. I had the opportunity to use them for some issues at my home. Before I called Brisk, I had called another local company and had the worst possible experience a consumer can have. Lesson learned. BS diagnostics, poor service, and simply tried to rip off a consumer. Tech recommendations were a full system replacement with not clear explanation of why it needed to be replaced. I sent an inquiry to Brisk and shortly received a reply. Appointment booked. Had the pleasure of meeting Kyle who owns the company. Expressed my concerns and issues. Kyle listened and addressed all of them. Did the diagnostics and explained what was going on and what needed to be corrected. He explained what he was doing and what the numbers meant on his gauges. I could not have asked for a better experience with Kyle and his company. Kyle's knowledge in his field is top notch. The world needs more people like him! In the end, Kyle replaced a part. Checked to make sure the system was function within operational parameters. All was good. Nice cool air, quiet AC unit, and a happy customer. Best part is Kyle explained everything and there was no BS. The charge was fair for industry standards. It would not have mattered because if it were more I would have paid it. Simply because Kyle is a true professional! So if you made it this far, call Brisk Heating and Air. You will not be disappointed. They a have client for life and will be the place I call for future HVAC services in my homes. A Big Thank You to Kyle and Brisk Heating and Air!
