He is extremely knowledgeable and took the time to clearly explain what was going on with our HVAC system and what needed to be done. He worked efficiently, made sure everything was completed properly, and didn't rush the job. It's clear that he truly cares about his customers and the quality of his work. The pricing was also very reasonable, which we really appreciated. He not only repaired our home air + heater device, but installed our smart thermostats and made sure the app was properly installed and running on my phone. This is the model we used: https://liketk.it/5J3Us If you're looking for someone honest, skilled, and dependable for HVAC repair or maintenance, I highly recommend GG Heating & Air Inc!

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.

When you are able to find service, that is such high quality at a reasonable price, I feel…read moreobligated to share the wealth. Marc from Comfort Air was everything I look for, when I hire an outside service. Thorough communication, efficient, knowledgeable, courteous, clean, honest and professional -- VERY difficult to find in Vallejo in my experience. How is it possible there's only 3 (now 4) reviews on Yelp? The fact that all of this comes with a very reasonable price tag, just seals the deal for me. My brand new dryer was taking 4-5 cycles to dry a load of laundry, after Marc cleaned the vents from the inside of the house, as well as from the roof, my dryer is now humming and such a pleasure to use! Not only did he clean it from both ends, but he also went through the attic to repair a door on the vent that was incorrectly installed. His price and service was so good, I'm just looking for things for him to fix now... lol. If you are having issues of any kind with your appliances, you don't need to look around any further, I've done the research for you! I highly recommend Marc at Comfort Air.

Electrify My Home replaced our old gas furnace with an electric heat & cooling system…read more From the beginning, they were great. Nic provided a very comprehensive presentation and walked us through the process. They provided an initial estimate, then came for a home visit to verify a few things. The estimate did not increase. We were able to schedule an install for the following week. They also coordinated some asbestos removal work we needed done. Communication was quick and thorough. The installation was done by Xavier and his team of 4. INCREDIBLE. Very respectful of our space-- at the end of the day, even on the days where they were cutting holes in the wall or dragging out old equipment, you couldn't tell they were here. Xavier was also great with communicating each day's activities and hours, and was mindful of my working from home and family dog. At the end of the job he walked through and explained how to use the system, as well as next steps for our permitting and inspection processes. There was a problem with a disconnected hose that was taken care of the next day. They also noticed some the asbestos abatement was not completed, and took care of communicating with the vendor to correct it. Nic called to follow up and make sure everything was working well a few weeks after the install. Would definitely recommend Electrify My Home! They are great to work with.
