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 had Copperfield Plumbing out to fix a copper water pipe that was leaking (March 2026). I never…read moretalked prices with them. I was quoted $380 by the repairman after he looked at the problem. It took him about 20-25'. The technician was skilled, polite and efficient. I wrote them a check, but I was not given a written estimate, nor was I given a receipt. NO itemized information on the charges at all. It seemed like a lot of money!!! I called the secretary later that afternoon and she had the owner call me back. He listened to my concerns and we arrived at a compromise. So, just be informed of the charges beforehand and get multiple estimates if you can. Copperfield Plumbing is a reputable and flexible business and a good choice if your due diligence is complete.

Part one of a two part foundation project Recently we had…read moreour house foundation repaired by Groundworks out of Fairfield. One bedroom had sunk by almost 5 inches as that part of the house had been built on fill. In order to restore the house to it's proper level numerous foundation jacks and floor leveling screw jacks were required. In addition some landscaping bushes and pvc sprinkler pipes had to temporarily removed. Groundworks had informed me prior to starting work what would be required to successfully complete this project and had my full approval. The house is now level, the doors no longer swing on their own and the interior cracks between the walls and ceiling joints no longer exist. Prior to the crew leaving the yard was cleaned up and the pvc pipes replaced. Best of all Groundworks will come back annually to the next 5 years and make any necessary adjustments. The Groundworks crew that made this happen was Andrew, the site supervisor, Charlie and Allen. Their performance and daily communication was superior on all levels. This is part 2. The Groundworks Poly crew of Anthony & Brian were very fast and efficient in completing their part of the foundation repair contract which was to level our family room slab floor. Fast, yes, but Anthony did take the time to not only explain what they were going to do but also walked me through the process as they were working. I have no problem in recommending them & Groundworks to other home owners who need to have their foundation repaired.
