While all companies are great and high-rated, Mercury stood out among all of them. They were the only company that actually went up into our attic during the estimate showing how thorough they are. Ian took the time to explain his thought process, was completely transparent, and never tried to upsell us. We also appreciated that the owner (Ian and Jason) was personally involved in the installation. Their dedication was impressive--they worked through a heatwave and even stayed overtime to get our AC running as soon as possible when they see how miserable we were during the heatwave. The workmanship was excellent, with minimal damage to our home, and they left everything clean and tidy. It's rare to find a company this honest, hardworking, and detail-oriented. Highly recommend!

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!

We loved the experience from start to finish!…read more Sam helped us understand the different units of work that needed to get done. He was thorough, even recording videos of his initial inspection so that we had a record. I especially appreciated that he called out Alameda regulations that were going to change in 2029 (this informed our decision to go with a heat pump now) On the day of the installation, we had an amazing experience working with Sam, Benny, Jesus, and Jorge. They were always very thoughtful and polite. Anything that might deviate from the original quote, they would give us a headsup. For example, they noticed that one of the pipes looked missing from the outlet in the yard, and that they would just charge us for parts if they needed to go out to buy a pipe and install it. Fortunately, the pipe was just hidden. They even went out of their way to help us fix one of our broken stairway steps. It was an incredibly smooth process, and we LOVE how quiet the heat pump is. (It's so quiet, we weren't sure if it was working!) My wife and I highly recommend them!

From the beginning, Daniel and his team were professional, honest, and easy to work with. They arrived exactly on time, and it was obvious they had a great deal of experience.

He patiently answered my questions, was willing to help whenever I had concerns, and never made me feel rushed. Everyone on the team was polite, respectful, and took great care to protect my home during the installation. It's refreshing to work with a contractor who truly cares about quality and customer satisfaction.

As an MVP member, I requested an annual HVAC inspection. Jesse was very professional and…read moreknowledgeable, and found physical issues with the furnace. I was surprised as the unit is only 13 yr. old with no major previous concerns during past visits. It was recommended that the furnace be replaced either with a new ultra-low NOx unit or with a heat pump. I asked for further advice and a second "advisor" visit was scheduled the following week. I met with Bryan and after airing out my concerns with ultra-low NOx and with Bryan consulting with his office, he still recommended the ultra-low NOx unit. The price that I was quoted appeared to be very high so I did my research and asked another company for a blind apples-to-apples quote, which came in $4,000 cheaper. The other company also told me that Vacaville is still allowing for low NOx installations (for about the same price as ultra-low), which Service Champions did not know. Since I am a long-term customer with Service Champions and have had good experience with them, I asked them to match the other company quote, which they did and even beat their price by about $400. Not only that, Service Champions did some additional research and concluded that a low NOx furnace still is permitable for install in my city. I would have given them 5 stars but I believe they should have known that low NOx furnaces are still allowed in certain areas.
