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.

Chill is a classic example of the type of business you should avoid. A repair guy (named Vik) came…read moreby to look at my AC system. He said the problem was the starter and said he could fix it for $460. While he was fixing it, I looked up the price of the part. It was $25. He was here for only 15 minutes. After the repairs, I asked him how much of the $460 was for parts and how much was for labor. He said about 50% for each. I then let him know that I found the part for $25. He responded that he doesn't buy the parts himself. So I paid $25 for parts and $435 for 15 minutes of work. Yes, I wish I had gone with another company.

We will definitely be repeat customers!

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!

Lazy people did not want to troubleshoot properly. Bought a new range and everything works now!! Go back to school!

Great HVAC Service -- Highly Recommended! I found Spot Free…read moreHVAC Air Service while searching for HVAC installers on Yelp and was impressed by their good reviews. 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!
