I recently purchased a promotional voucher for a AC cleaning from 313 Local Duct Cleaning Duct Cleaning. Cliff, who i believe is the owner, was great up front in outlining the terms & conditions and making sure I was aware of any additional costs (up to 12 vents). Service times were quite flexible, and overall the AC cleaning was up to my satisfaction. I have a small townhouse so it didn’t take long for them to finish up. Hook ups to the AC was fast. Only thing I was disappointed about was the voucher called for a new AC filter which I did not receive, assuming the tech may have forgot. Overall, the service was acceptable for the price paid for and I would recommend and use these guys again.
