Fernando went above and beyond to diagnose the issue at hand and had the right solution at his fingertips, every time. He presented a couple of options, and forged ahead with what I was comfortable with. He took his time to ensure everything was in tip-top shape after installation, and as a result, I have a fully operational and fine-tuned system on the precipice of a heatwave. I also appreciated that Fernando ensured everything was documented and had a zero-pressure approach. I also found Art of Comfort's pricing to be fair and transparent. Thank you, Fernando, I'm so grateful for your professionalism!

My husband and I evaluated three vendors around the area in great detail and despite Chill coming out slightly more expensive than others, we felt they were the most thorough and comprehensive during the consultation (and the many follow-up questions I had). They were also able to squeeze us into their busy schedule so we could get AC before the heat wave! During installation, they ran into several challenges with placement of the new unit and some wiring that needed more attention. They worked through and around them to make everything work out in the end. I really appreciate their flexibility and expertise to navigate all the roadblocks without changing the scope of work. TIP: Measure the space where the unit is going to be placed and make sure the new unit will fit OR that you discuss this before the project starts.

Excellent Service from Start to Finish!…read more I recently had my entire HVAC system replaced by Air Design Heating & Cooling, and I couldn't be happier with the experience! From the initial consultation through the final installation, Don was fantastic to work with. He took the time to answer all my questions, explain the different equipment options, and make sure I understood exactly what I was getting. I really appreciated his knowledge, honesty, and willingness to collaborate throughout the process. Don and Jess did the installation and where they were equally impressive. They arrived on time, were professional, courteous, and extremely knowledgeable. They took great care of my home, kept their work area clean, and paid attention to the details throughout the installation. It was clear they took pride in their work. What stood out most was the communication and collaboration. Don and Jess made the entire experience feel comfortable and straightforward, and I never felt rushed or pressured. Replacing an HVAC system is a significant investment, and it's reassuring to work with people who genuinely care about doing the job right. I'm extremely happy with the new system and the overall experience. I would absolutely recommend Air Design Heating & Cooling to anyone looking for a knowledgeable, professional, and trustworthy HVAC company. Five stars all around!

I offered to compensate him for his advice but he declined. He's earned my trust and future business. He's an oasis in a desert of salesy HVAC companies.

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!

I contacted them and received a fast response. The team leader, Anson, is definitely a tough negotiator, but he delivers on his promises. The installation was completed on schedule, and the work was done neatly and professionally. The team members, including Brandon, Omar, Noak, and others, were professional, friendly, and efficient. When the first inspection did not pass because the existing return-air lines were based on an old design that did not meet the current standards, Anson took responsibility and sent a second team to make the necessary corrections. They went above and beyond to get everything brought up to the new requirements. The final result exceeded the inspection requirements, and I'm very happy with the quality of the work and the service overall. Very good service and highly recommended! - Kent S.

The quoted price for a two-head unit with external pump was in line or lower than the competing bids, backed by an extended multi-year warranty as Mitsubishi Diamond Certified installers. Heat pumps installed alongside existing central air is not an uncommon request, but we had a great conversation with Brook on how we might update to a more modern system in the future, given our original(!) furnace's age. Side questions for him aside, we had a thoughtfully sized system outlined and quoted within a day, and scheduled within two weeks. Our experience with the installation was similarly great, with the team arriving promptly as scheduled and taking the care to put on shoe coverings moving through the house. Everyone was polite and efficient, bringing the plan to life and bringing us in early when there were onsite decisions to be made in our unique spaces. When an issue arose on the cooling not blowing as cold as we had expected, they were quick to assist with troubleshooting, and had it fully remediating within the week. Permits are still pending due to the Oakland backlog, but their lead electrician will also be onsite during the inspection process so I have no worries there. While our immediate need during the heat wave this Spring was cooling our living spaces, I have full confidence that whenever we go to multizone heating and cooling, Spot Free will be our go-to experts!
