Our Story

About Summit

Family-owned and operated since 2002. We built Summit on one principle: do the job right, treat people honestly, and the rest takes care of itself.

22 Years Serving Northeast Ohio

Summit HVAC & Plumbing was founded in 2002 by Mike Donovan after nearly a decade as a field technician. Mike had seen firsthand how homeowners were often overcharged, given unnecessary repairs, and left with confusing invoices they couldn't understand.

He started Summit with a simple promise: written flat-rate quotes before any work begins, honest recommendations, and technicians who take the time to explain what they're doing and why.

Twenty-two years and 14,000+ service calls later, that promise still drives everything we do. We're still locally owned, still answering our own phones, and still sending the same quality technicians we'd trust in our own homes.
