Last week, I got preventative maintenance service for our 2 HVAC units. The technician called me to let me know he was on his way and showed up right when he said he would. He checked out our 2 units, tested the components, cleaned everything and then gave me a clear and concise update on my HVAC units. The price was right, the service, too, was less than an hour. It gave me such great peace of mind to know that my units are doing great thanks to Total Air's preventative maintenance service.
