“The equipment is working fine, the service was good, the techs were great, I was very satisfied until the blower motor went out after the first year. The part was covered and I had to pay the labor. It took the tech 15 minutes to replace the part and I was charged $$500. I was told they charged by the job and not by how long it took. That is wrong. I will never use Casteel again or recommend them for service. Knight was bought by Casteel.”

“You can't always guarantee that the technician that you requested will be the one to come. They wait until the day of your appointment to inform you that the technician that normally comes is no longer with the company and I had to be the one to ask if my technician would be the one coming. They didn't willingly offer the information about the technician no longer being with the company.”

Review by Snellville, GA Homeowner

“I had the ready maintenance that I had set up with Knight Air Conditioning & Heating Co. and Casteel Heating & Cooling seemed as though they were trying to sell me another AC unit even though I am not experiencing any issues with my current unit.”
