I called this morning and they had someone out by early afternoon. George was fantastic! He identified the problem, made the repair and stayed until he was sure it was working properly. I highly recommend Duncans for all of your AC and heating needs.

They came out to the house only a few hours after I called. Temporary fix until permanent fix could be done. George was the tech and was great. Explained what was up without talking down to me and made sure I knew/understood all the particulars.

A bucket was placed under the pipe. He stated that I would have to periodically empty the bucket so that it would not overflow. It's now 9 am, almost
