“We’ve worked with Trefz Mechanical on more than $300k in projects for retirement communities that included HVAC and electrical overhauls to support major community renovations. Trefz’s project manager was always responsive and communicative. Their field guy, who was Trefz’s main contact on site, was also very helpful, productive and courteous to the client and residents in the communities where we were working.”
