Killman Heating & Air is one of our favorite companies to work with. Their excellent customer…read moreservice is unmatched, and the pride they take in their work is apparent from start to finish. We recently had been having heat issues in our building, and in one day Andy Killman was able to personally oversee the installation of a new unit to fix our problem. While they ran into unforeseen delays and snags, they kept at the job and knocked it out in a timely manner. On top of that, they stuck with the original quote they gave us which was greatly appreciated. As they were loading up their equipment, we noticed a totally separate and possibly minor issue - a vent that we didn't need and might have been contributing to our heat problem. Without skipping a beat he had one of his workers climb up on a ladder and fix the vent, no questions asked. You can't go wrong working with these fine folks. Thank y'all for everything you do.

They did not try to oversell me like some of the other HVAC companies and their recommendations were exactly what I needed. Recently we had some issues with the ductwork/damper and they came out the next day to inspect it and make sure the new HVAC unit was running correctly. Next day service is rare for such a minor issue. Killman Heating & Air is a class act.

From the time the Tech recognized the problem until the new system was installed, the team from…read moreCassell had been nothing but professional, accurate and considerate. We are very pleased with the service, price, value for the work and response of Cassell Brothers. This was our second unit total replacement, the last being in 2020. Reading recent reviews one could be scared away. That is not our opinion. Justin identified the inoperable problem in our 40-year old unit, got us in immediate contact with Doug (who came out on a Saturday). The replacement team of Dave, Carl, Donnie, Walter and Favian removed the old system (including ductwork) and installed the new system in less than 6 hours (in an attic over 95 degrees). They cleaned everything, went through the operations steps with us, and followed up two days later to complete one task. I would have given them a five-star but for one item still not resolved with our Trane unit from 2020--requires another Trane specialist. We would use them again and will carry the Comfort Club program for the forseeable future. Thanks Cassell for getting us back in comfort before the heat really builds!!

I am writing this to warn other homeowners in the Midlands to check the stickers on the units…read moreCassell Brothers installs. On 12/31/2025, I contracted and financed $6,280 for a top-of-the-line, high-efficiency Rinnai SENSEI RX (0.98 UEF) condensing tankless water heater. Instead, they installed a much cheaper, standard-efficiency RE199e (~0.81 UEF) unit. The unit they installed is a base-model, non-condensing unit that typically costs $1,000 less than what I paid for. Because it's the wrong unit, I also lost out on a $350 Dominion Energy rebate and have a $600 Federal Tax Credit liability. I brought this to the manager's attention three weeks ago. Since then, I have been repeatedly ghosted and ignored. They are happy to take premium prices for builder-grade equipment, but they refuse to answer the phone when caught. I have officially opened a merchant dispute with GreenSky and filed formal complaints with the SC Residential Builders Commission (LLR) and the SC Department of Consumer Affairs. Save yourself the headache and go with a company that actually installs what they invoice you for. Check your model numbers! ***UPDATE*** finally after I reached out to the BBB, the Department of consumer affairs, wrote a yelp review and a google review, I finally got a phone call back. funny how that works. They called my brother and he declined their phone call because it was a New York number. So they called my wife to get ahold of me. Somehow they think they can say they tried reaching out to me "multiple times". if that is the case Robbie, show a screenshot showing where you tried to get ahold of me? I will post all of my evidence showing you bait and switched units on me. Funny how I did not even get an apology or explanation of what happened when your manager James called me this morning, he just said, " instead of trying to the math, we will swap out for the correct unit" and wanted to schedule a time. ***UPDATE*** I have reached a settlement with Cassell Brothers. In the end they did the right thing and corrected the situation. Even though there was a lot of back and forth in the end, everyone stayed professional and I am grateful for that. I appreciate that management stepped up to make it right. I Consider this matter fully resolved and appreciate the company taking the necessary steps to endure I was taken care of as a customer.
