In season 12, episode 13…read moreof King of the Hill, Hank Hill talked about the importance of having a reliable professional on tap for projects. Well, Simon and Marasigan is my HVAC guy. Best service you'll get in Solano (and a little bit of Contra Costa) Simon owns the company, no middle man, and he has more than 17 years of experience working in HVAC. When I requested service for my AC, he would've literally been able to come check it out within half an hour! I wasn't able to do that cuz I was working, but he was able to work with my schedule. The flexibility is always great. When he came by, he was immediately able to diagnose the problem, told me exactly what I need, how much it was, and even taught me how to maintain it and diagnose issues on my own as well. No frills, no upselling, saved me money wherever he could, and most importantly, the job was future proofed as well. I got a great price for the work that needed to be done, and it was also done quickly. He even came early! What makes him stand out above the other HVAC services is that he even taught me how to increase the longevity of my unit. I knew that he really cared about the quality of his work, and making sure his clients are taken cared of. So yeah, just go to him!

Nate provided guidance on selecting the right model for our needs. He also recommended an Air Scrubber to help with seasonal allergies priced way below competitive bids. We had a 5 star experience with the air duct cleaning with Same Day Air a week ago and looked forward to our new system. Brentwood can get quite hot in the summer. Come install day, Roberto arrived early to prep for installation. He had help from 3 additional team members. Roberto and Edward powered through the installation and by mid afternoon we were enjoying our new system. Edward installed our nice new Nest thermostat which enables us to use an app from our phone. Nice! Excellent job, highly recommend!

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.
