I had a furnace issue at one of my rental units, but I was out of town. I had my tenant call Pro-tech (on a weekend), and they responded right away. They provided pricing for both a weekend call, and if I could wait 2 days. When the service tech arrived on the following Monday, , he promptly fixed the issue, called me with an update, and I received an invoice via email within minutes of him finishing the job. Very professional, friendly office staff and service guy!
