Best Heating & Air Conditioning / HVAC In Irmo

“We just had Chris Chavez come out and service our Air Conditioning unit. He is very articulate and knowledgeable about the unit. He was very knowledgeable and polite. He arrived on time and took the time to explain everything he did on the unit. He is a loyal employee and your company is very lucky to have him. I would highly recommend Cassell Brothers for your heating and cooling needs. Sincerely Karen Kaiser“

“Very knowledgeable technicians, Chris and Nick explain everything and was very professional! Great company to take care of your HVAC needs.l“

“David Tate the salesman goes above and beyond for his customers. I have used them for 5 years replacing both heat pumps and installing a generator. Their crews are very professional and the installs went great. David is not your typical salesman once he sells you the equipment he keeps in communication and always responds quickly. Wilson’s in my opinion is a great company and I will continue to use them for all my hvac needs.“
