In 2008, my family and I decided to begin a business venture: Cassell Brothers Heating & Cooling. We have nearly 60 years of combined experience in providing exceptional customer service. The lessons we have learned over the years will ensure your peace of mind. We guarantee your satisfaction with our services and our abilities.

A geothermal heat pump or ground source heat pump is a central heating and cooling system that transfers heat to or from the ground. It uses the earth as a heat source in the winter and a heat sink in the summer. WaterFurnace units can save you up to 70% on heating, cooling & hot water by capturing the clean, renewable energy in your backyard. Upgrading to geothermal just got more affordable, and with the combined 55% state and federal tax credit set to expire the end of this year, the time to act is now!

Through summer storms or blizzard conditions, nothing stops a reliable and efficient Trane from keeping you comfortable all year long. Now is the right time to upgrade your old system or repair your existing system to be ready for any season. If your AC system is 10 years or older, then it may already have reached its full lifespan. Find out if an aging AC or heating system is costing you more than you think and when you should replace it. Your AC might just need a little TLC to keep it running at full efficiency.

At Cassell Brothers Heating & Cooling, customer satisfaction is our number one priority. If you're searching for HVAC installation, maintenance or repair services, everything you need is just a phone call away. Some of our services include upgrading the comfort systems on older homes, fixing new home systems that don't work, providing indoor air quality options, repairing existing comfort systems and inspecting existing set-ups before you purchase a new home.

Worse, it can leave you without heat or air in your home, which can be a serious health hazard to some.

If you want to stay cool and comfortable during the summer, you'll need a dependable central air conditioning system. That's why Cassell Brothers Heating & Cooling offers complete AC installation, maintenance and repair service for residential and commercial customers in Columbia, SC and the surrounding areas. When it's time to purchase a new air central air conditioner, it's important to remember the contractor you choose will have the biggest impact on your comfort and operating costs.

If you own a business, you know the important role your HVAC equipment plays in keeping your customers and employees happy and comfortable. That's why the experts at Cassell Brothers Heating & Cooling offer complete commercial HVAC repair, installation and maintenance services for businesses in the local area. A commercial heating and cooling breakdown can be costly and disruptive. While many HVAC contractors claim they can repair commercial systems, most of them lack the skill and experience required to address complex problems related to the commercial refrigeration cycle and 3-phase electrical systems.

At Cassell Brothers Heating & Cooling in Columbia, we understand that the indoor air quality of your home is important. Because dust mites, pet dander, cleaning chemicals and even the materials used to make household furnishings can leave pollutants in your home, the IAQ (indoor air quality) can decrease. The good news is that we have a solution. With HVAC system installation, proper air filters and UV lights, the quality of the air in your home can greatly improve. We understand that your highest priority is keeping your family strong and healthy.

Efficient, effective and extremely versatile, heat pumps are popular HVAC options for homes and businesses in South Carolina. Should a problem occur with your heat pump, trust Cassell Brothers Heating & Cooling for expert heat pump repair services. Reliable performance is one of the things people love most about energy-efficient heat pumps. If not properly maintained, however, components like compressors, condensers and evaporators can falter or fail. Even a minor issue can compromise your comfort and cause further damage to the equipment.

I would like to thank Tyler at Cassell Brothers for restoring the harmony of heat back in my home. My family and I, before calling Cassell Brothers, dealt with another contractor who was below subpar and left us without any heat for 4 days on the coldest days and nights at the beginning of this year. On the forth day, I called Tyler, who came over the same day and immediately diagnosed our problem. He was also able to restore heat in our home with no delay. Tyler was very professional, knowledgeable, and extremely reliable. He performed the necessary repairs to the highest quality and at a reasonable price. My family and I cannot thank you enough Tyler and we are forever grateful for the service you provided.

Great service and staff. I'm so glad we found this company and will certainly recommend them to friends and family.

Cassell Bros. recently did work at my daughter's house. They were the best! Highly recommend this wonderful, honest company!

What's new?

Happy International Women’s Day to not only the women who make our company extra special but to every woman out there making a difference in the lives of others! We see you and we appreciate you!
