Best Heating & Air Conditioning / HVAC In Irmo

“I had the pleasure of meeting HVAC Tech Pablo. From start to finish, he explained every action he would take. My lower level heat stopped working, so I called to get some help. I got an appointment right away (member), same day to be exact. Overall the service was fast, I know what was wrong, and know exactly what I paid for. Pablo is the MVP of this review, it's good to see Cassell Brothers hires educated and professional techs who are motivated to get the job done. Tank you!“

“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.“
