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.
Standard home (1,500-2,500 sqft) on quarterly: $89-119 per visit, no setup fee, cancel anytime. Larger homes and acreage are quoted individually.
Yes. Our standard products (Onslaught FastCap, Termidor SC) are pyrethroid-based and dry within 30 minutes. Once dry, they're safe for pets and kids. We use bait gel inside cabinets — also safe, sealed in the gel.
You call us, we come back free. The residual takes 7-14 days to fully cycle through a colony. If you see activity after 14 days, that's on us — free re-treat, every time.
