Bojan did a great job with my Hvac maintenance today. He identified a couple of issues, explained them in great detail and fixed them. He also made recommendations about my water heater which I appreciated. Bojan Is efficient and professional. He does a great job explaining issues and took time answering my questions. He also solved a perplexing situation that I have been experiencing with my ducts and I'm most grateful for his knowledge, experience and professionalism.

Bojan provided thorough and expert service yesterday for my twice-yearly heat pump service. He tells the customer everything about their system and how to maximize its efficiency. He is highly experienced, an asset to your company, and the person I always request for my heat pump service. He would be an excellent trainer for new heat heating/cooling technicians.

It is fall, and the cold arrived earlier than expected, right when our heating system suddenly stopped working. We’ve lived in our home for two and a half years, and the system hadn’t been updated in 19 years. Thankfully, TriState Home Services came to the rescue! A huge shout-out to Gary and Justin for their excellent work in getting our home’s heat back up and running.
Best,
Moges Ambaw and Yabissira Afework

Bojan is the best at what he does, both technically and professionally. He shows up on time and always gives me a heads up that he’s on his way. If there’s an issue, he’s up front and always knows how to fix it. Bojan had an apprentice, Aiden, working alongside with him today during the semiannual HVAC service appointment, it’s good to see that Bojan can share his knowledge with the next generation of solid, reliable, hardworking technicians like Aiden.
