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.

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.

I texted Fred yesterday, on a Saturday, because our unit in our new house (Not the one he installed) was having some issues. He came out on a Sunday and fixed it in 30 minutes, and DIDN"T charge us.
