"Floyd with Ducts Columbia is now the only company I will use for duct cleaning, sealing vents, & dryer vent cleaning. His level of care and detail completing my project left us feeling like we were taken care of by family. He asked my questions, addressed concerns, and educated me in areas where it was important for ongoing safety and health. If I could rate higher than 5 stars I absolutely would."

"One of my AC units was not working correctly so as always I went to Angi to find someone qualified to do the work. CALL DAD HVAC called me right away and said they could come out that afternoon but due to my schedule had to wait until the next morning. Daniel arrived here promptly and worked all day until all the work was completed to my satisfaction and approval. I was so pleased with the work I decided to sign up for a year's contract with them which was very reasonably priced. If someone needs any HVAC services/repairs I highly recommend CALL DAD!"
