Call Prescription in the late afternoon of July 4th expecting to have to leave a message and having to worry about our Air Conditioning on one of the hottest and humid days of the year. Mike answered and was on a job, but thought he might be able to swing over between jobs. He called me back within 10 minutes and said he would be over to our house in 30 minutes…45 minutes later, Mike has assessed and fixed the issue. He also helped answer some questions we had regarding replacement of our furnace and AC. Very impressed with his service, speed and knowledge. Will for sure be using him again.
