The AC is now blowing cold again and working great. Justin was very professional, explained everything clearly, and completed the work efficiently.

Thanks again for getting our home cool and comfortable again !

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.

Once again, Copperfield Plumbing comes through with flying colors. I have to admit I was…read moredisappointed to hear Luis left the company, but Josh showed up in his stead. Josh was prompt, courteous, professional, and respectfully put covers on his shoes before entering my home. Josh diagnosed and addressed the problem quickly and efficiently. Less than 24 hours between call and completion by the way! Highly recommend these guys.

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.

Alex sent our technician, Rojo, who helped install a new 40-gallon gas water heater in our indoor utility closet, and he was incredibly diligent, professional, and efficient from start to finish. Installing a tank in an inside closet can be tricky, but Rojo handled the entire job seamlessly in just 2 hours. He replaced everything with high-quality components, including: * New hot and cold water flex lines * A brand new water shut-off valve * A new gas flex line and sediment trap * Fully reworked earthquake straps (to meet California safety codes) * Properly updated T&P line and venting He also took care of the removal and disposal of our heavy 18 yr old tank, leaving the utility closet completely clean. If you want fair pricing, expert specialized service, and a technician who respects your time and home, call Water Heater Masters and ask for Rojo. Highly recommended!
