The Person Behind the Company
Owner & ASE Master Technician · License #ASE-CMT-1129
Summit Comfort HVAC was founded by David Chen after 10 years working for a large HVAC corporation. Frustrated by the pressure to upsell and the lack of personal accountability, David started Summit with a simple promise: honest diagnostics, fair pricing, and work he'd stand behind with his own name. Fifteen years later, that promise hasn't changed — it's just backed by a bigger team and 187 five-star reviews.
"Keep every home comfortable, safely and honestly."

The questions homeowners ask before handing over the keys to their HVAC system.
Yes — that's most of what we do. Bring us a dealer quote, we'll tell you which line items are real, which are padded, and what it should actually cost. Second opinion is $0 if you bring the quote in writing.
3 years / 36,000 miles on every repair, parts and labor. If the same problem comes back in that window, we fix it free. Not many shops outside the dealer network offer that — we can because we use better parts.
