Demo AC / About
A family-run shop that's been answering the phone in this valley since 2014.
Four people, four trucks, one promise: pick up the phone, quote it flat, and don't disappear after the install.
Owner story
Meet Mike Reyes.
Mike spent 14 years on a truck for two of the bigger Valley HVAC outfits before starting Demo AC in 2014. The reason he started his own shop is the reason this site exists: he was tired of watching homeowners get upsold things they didn't need.
Twelve summers later, Mike still runs dispatch himself most mornings. The three techs on the truck - Diego, Marcus, and Ray - have been with him an average of six years each. It's not a big shop, and we're not trying to grow into one. We'd rather be the four-person crew that's still here in another twelve.
"If I can't explain the repair to my mom in two sentences, the quote isn't ready yet."
