WHAT OUR CLIENTS SAY…

“Among the many aspects that impress me about Trefz Mechanical is how conscious they are of their environment and how incredibly organized they are. They completed a $125k HVAC and electrical upgrade project for us and made sure they were as unobtrusive as possible since our church was functioning with services, weddings, etc. at the same time. You’d hardly know there was this huge project going on behind the scenes! They’re also a super “clean” company, which is a rarity these days. Moreover, after completion of the job they presented me with this incredibly organized, alphabetical parts binder complete with diagrams and even a table of contents. I would give them a big A+ overall and highly recommend them to others.”
