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.

They removed the old heat "oozer" in the living room, used the existing flue and mounted a lower unit as I was hoping. Three years later, they've been out twice for what they consider warranty work (a small pump failed) and charged me zero for the house call or the parts. They also helped me find a loan and proceeded the PGE rebates for me.

We had our AC stop cooling in the middle of a hot day, and with two young kids and a dog at home,…read morewe were pretty stressed. Keon Garcia came out and did an outstanding job. What I appreciated most was that he didn't just start replacing parts. He thoroughly diagnosed the system, explained what he was testing, and walked me through the results. He showed me that the capacitor was testing low, the contactor was worn and pitted, and even performed a megger test on the compressor to verify it was still healthy. After the repairs, he confirmed everything was working properly by showing me the compressor amperage had dropped back to normal and that the system had an 18-degree temperature split. Keon was patient with all of my questions and never made me feel rushed. He explained the pros and cons of the recommended repairs, including the hard-start kit, so I could make an informed decision instead of feeling pressured. I really appreciated his transparency and professionalism. By the time he was done, our AC was cooling properly again, and he even worked with us on the final price. If you're looking for an HVAC technician who is knowledgeable, honest, thorough, and takes the time to educate his customers, I highly recommend Keon Garcia. Thanks again for getting our family cool again!

To our dismay, our 22+ year old AC unit stopped working at the start of a weeklong heatwave. We…read morewere able to secure a next morning appt with Advanced Plumbing, Heating and Air, and Victor came out, assessed the furnace and outside unit, and let us know that it was pretty much kaput (which we expected). Victor provided detailed and thorough information, and showed me all the areas that were broken/corroded and were contributing to the overall dysfunctions. We had had our dryer repaired a few weeks ago by different vendor, and Victor's assessment aligned with that vendor's assessment -- that we were possibly dealing with a full HVAC issue. Victor was able to apply a bandaid fix to hold us over in the heat and scheduled an appointment with Mark, who came to our home later that evening to do a further assessment and to provide us replacement and financing options. We were able to secure an installation appt of the new HVAC system two days later, in which, Bobby and his team came in and took care of. The installation took just under six hours and from what I could tell, went smoothly, though I did feel bad that they were installing the system on a very hot day. But they didn't complain and remained professional and courteous. Overall, we felt well-informed and well taken care of by this company! All the employees we interacted with were professional, personable, laid back, and provided us great, fast, and generous service and care. We ran into some hiccups with financing but Mark helped us iron that out quickly and smoothly. The investment of the new HVAC system was resonable and fit our home goals. I appreciated that we didn't feel upsold to or pressured, and that they took the time to understand our pain points so that we could make the best decision. We're happy with our new HVAC system and are looking forward to seeing the physical and financial benefits of having an up-to-date and more efficient system. Would highly recommend.

The person who answered the phone was professional, patient, and courteous, even as I worked through my concerns and asked some repetitive questions. At no point did I detect any frustration or impatience, which I truly appreciated. Jazz was also able to schedule an appointment for the following day. Joe was assigned to provide my estimate. He arrived on time and had a great attitude from the start. He was patient and willing to listen to all of my concerns, answer my questions, and discuss different alternatives. Before leaving, he provided a detailed quote with different payment options, which made it easy to understand the choices available to me. I requested the consultation because I was experiencing water hammering when using multiple fixtures. Since diagnosing water hammering can involve a process of elimination to determine the underlying cause, I received different opinions and recommendations from the plumbers I consulted. Jazz recommended installing a new water hammer arrestor along with a washing machine box. One thing I especially appreciated about Joe's explanation was Jazz's no-frustration guarantee. As it was explained to me, if additional issues arose during the repair process, Jazz would address them at no additional cost. My primary hesitation with moving forward was that installing the new washing machine box could require cutting into the wall. I was advised that Jazz would replace the drywall, but I would need to hire someone else to finish the mudding and painting. I understand that this may be standard practice in the industry, so I don't consider it a negative reflection on Jazz. It is simply an additional project that I am not interested in taking on at this time. Ultimately, each plumber who provided me with an estimate had a different opinion about what might be causing the water hammering. Given the uncertainty surrounding the exact cause, I decided to start with the simplest and least invasive solution: installing a washing machine water hammer arrestor, which was recommended by another company. Although I ultimately decided to pursue a different approach, I had a very positive experience with Jazz throughout the consultation and estimate process. I especially appreciated the excellent customer service during my initial call, the quick scheduling, Joe's professionalism and positive attitude, his willingness to listen to my concerns, and the clear options and pricing he provided.
