Steve always does a great job!

I like to have Steve comes to my house because he is familiar with our furnaces and air conditioners. And he always does a great job.

Wanting to see if/how much air is being lost in our vents since we recently found and temporarily patched a hole in the ductwork to one of our rooms. Also interested in a quote to fix said issue.
