David tested our A/C unit to make sure everything was working as expected and then cleaned the outdoor A/C unit and also went up into our attic space to show us how and where our air filter goes and how to replace it, all while being very respectful about keeping things clean. 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!

I wish I could leave 10 stars for this business. My AC unit has not been working since last year. I…read morecalled Millers to come out to give me a quote on replacing the AC unit as Eagle Air had quoted us at 30k to replace and install a new AC unit. Alan a manager came out to inspect and give us options on how we can proceed in replacing our current AC. He was incredibly well informed and very knowledgable in explaining what our best options were. He called the office on the spot to set up an appointment for a service tech to come out and see if we could first fix the AC before doing a total replacement. Alan offered to bring us a window AC unit due to me being in my late 3rd trimester to make sure I am comfortable in the mean time. Sonny the service tech came out and found the problem with the AC unit in record time! We had a previous company come out and told us it was the compressor and quoted us at 7k to replace. It was in fact the capacitor that was not working. Sonny fixed the issue incredibly fast and now we have perfect working AC just in time for the heatwave. He was extremely professional and helpful in answering all of our questions. 10/10 I could rave all day about how wonderful Alan and Sonny were in helping fix our AC issue in a timely manner with out breaking our wallets with a baby on the way. I will be only using Millers Air for life and will let all my family and friends know this is the only option for AC services they'll ever need. Alan and Sonny I whole heartedly thank you 1000x over for your incredible service and kindness!

Miller's AC & Heating was my first call, I requested they repair our Dual Heating System. They had an appointment the very next day. Tony arrived early. He immediately understood the problem with the dual system. He skillfully set it up so it would work while he ordered the part required. He explained everything, was super friendly, quick, and efficient. We are excited to have heat while we wait for our part to arrive and be installed. Toni was a pleasure to work with, and we look forward to a fully functional Heating System. Sonny finished the job today...he was a pleasure to work with. Our builder did not mark any of the components, fortunately he solved the puzzle, and we now have a fully functioning Dual Heating System.

Eventually, it became obvious that tech clean was not going to pony up my $4000 rebate so I went forward anyway and had the unit installed.AIS We're consummate professionals through the whole process, and I could not be happier with the unit that was installed. fast forward too, late November 2025 when I received a call from Genell Branum Who is the MVP in all this, she informed me that she never gave up on my $4000 rebate and finally got it handled and the check was in the mail which it was as it arrived three days later for $4000. I would not even consider another company for any of my HVAC needs at this point these guys were Rockstars start to finish.

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.

Everyone who came out was professional, friendly, and did a great job. The reason I'm giving 2 stars is the pricing. I decided to ask them for a quote to install the electrical for our hot tub. I already had two quotes for the exact same job at just over $2,000, and Service Champions came in at around $5,000. I was shocked at the difference. I understand companies have different overhead and pricing, but more than double two other licensed contractors for the same scope of work felt very excessive and honestly made me question doing business with them at all going forward. It's unfortunate because I had a great experience with their technicians and was happy with the HVAC and water-heater work. But after seeing that electrical quote, I would definitely recommend getting multiple bids before agreeing to any work.
