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!

In a world where everyone is trying to LIE, and take your hard-earned money, thank goodness there…read moreare a few HONEST companies out there. Marasigan Heating and Air is one of these companies. Simon was thorough, and explained there was really nothing wrong with our furnace. He tested it, and it worked fine. He didnt charge me anything at all. We asked if he could come out to clean our AC. And you know what he said y'all? He said once every Summer just get your hose, put it on jet, and spray the vents out. That's it. We were ready to pay him to come out and clean our AC unit and Simon, said we didn't need to. I mean, who does that nowadays?! Full disclosure: I had another furnace company come out and check my furnace. This company not only told me my motor was broken (BS! ), and also would cost $950 to fix. They also greatly emphasized replacing the whole system for $12k. I have no doubt this company would also charge a grip to come out and clean our AC unit. So, my brothers and sisters, please DO NOT call ANY, I repeat ANY other furnace repair but Marasigan. It is a small local, family-owned business that unmistakenly takes great pride, holds the utmost integrity in their work, and most importantly, is completely honest with their customers. I whole-heartedly recommend them to any of my own family members and I highly recommend them to all y'all. If your heater or AC is acting up, better call Simon! If ykyk!

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.

Come install day, Roberto arrived early to prep for installation. He had help from 3 additional team members.

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.

He detected and replaced a blown capacitor and got the A/C working right away. He measured all the components of the system outside and tested the cooling effectiveness inside the house. He was happy to have me out there as he worked and explained everything he did. What he did not do: upsell / recommend a new system install. Though he did explain that our 22 year old unit was likely reaching the end of its service life. These guys are very straight shooters in an industry with some sketchy common practices. Price for analysis of both systems and the repair of 1 unit was very reasonable.
