Great professional service! Kept me informed on timing and options and they worked late to make sure installation of replacement AC was completed in one day.

I recently had Mateus from Temp Masters come out for an HVAC repair and I can’t recommend him enough. He was willing to spend the time with me and fix other contractors mistakes. From the start, he was professional, friendly and gave me a fair transparent quote. What stood out to me is that he stayed until the job was complete on the Friday before Memorial Day.
Had a great experience with Temp Masters. Kept me updated on their arrival time, informed me of what he was going to be doing and listened to my questions/concerns!
