Called them and they came out the next day (on a Saturday morning no less) and fixed the issue. Would highly recommend this company.

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.

EXTREMELY DISAPPOINTED-BEWARE OF PRICING PRACTICES!…read more On 5/22/26, I had a technician from Cassell Bros come to my home to inspect my breaker box. Initially, I was told that five breakers needed to be replaced. The technician stated he had to leave to purchase them because they were "too expensive" to keep stocked in the van. At that point, I was quoted $2995.00 for the work. After returning and beginning the repair, the technician discovered an additional breaker that needed replacement. Interestingly, this breaker was available in the van. The total was increased to $3594.00. When I asked about the cost of the breakers, the technician showed me what appeared to be a pricing image indicating the breakers cost $599.00 each. Trusting the information provided, I approved the work and paid the invoice. The entire visit lasted roughly 30 minutes. Later that day, I noticed the breaker packaging left behind in my recycling bin. Out of curiosity, I researched the exact breaker models and found them listed at Home Depot for approximately $75 each. To verify, I personally went to Home Depot with the packaging information and confirmed the breakers were indeed priced at $75.31 a piece (I have pictures as proof). Concerned about the significant markup, I contacted the company seeking an explanation. Initially, I was told no manager was available and that someone would return my call, but I did not receive a call back. After calling again, I eventually spoke with someone named Broderick. During the conversation, I was told the company is " a business trying to make money." I was offered a 20% discount, which I did not feel adequately addressed the issue. I was also told the only other alternative, and I quote was, "I CAN COME BACK TO YOUR HOUSE AND PUT THE OLD BREAKERS BACK IN." Another concern is that the invoice provided was not itemized, making it impossible to see the breakdown of parts and labor charges. What reputable company doesn't give you that information? One that is not practicing ethical business. I understand businesses need to make a profit, but this experience left me feeling misled and taken advantage of. If it hadn't of been for their "smart" technician leaving the packaging in my trash, I would have never questioned this service. I encourage anyone considering this company to ask detailed questions, request itemized pricing upfront, and compare cost before authorizing repairs.

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.

This past Wednesday the leak test was done. Freon has leaked into the pan. I was told the coil would be ordered and they would call with a time to replace. I called this morning to follow up on repair and was advised the local Lennox dealer has a shortage. The owner said he was working on it and would call me around lunch time. I called on a Thursday to schedule routine maintenance on our units. By Friday night our downstairs unit decided to go crazy! I was able to text to se if I could be seen sooner and they came out then next day. Ryan drew a diagram to explain the unit, service in attic and how it works. From there he explained what he suspects is my issue and the plan. He was able to "bandaid" my issue and will be back this week to do an official leak test.
