A contractor that knows Pasadena
Pasadena also gets real weather at both ends: San Gabriel Valley summer heat that regularly tops the LA basin, and crisp winter nights at the foot of the mountains. Systems here have to genuinely perform in both seasons.

Historic Pasadena homes need HVAC that doesn't compromise their character — high-velocity small-duct systems, carefully routed ductwork, and mini-splits placed with respect for original architecture. That's craftsmanship we take seriously.

HVAC in Pasadena — common questions
Can you add central air to a historic Pasadena Craftsman without damaging it?
Yes — it's some of our favorite work. Depending on the home, we use attic-routed conventional ducting, high-velocity small-duct systems, or discreet ductless setups, always with the home's original details protected.
Pasadena gets hotter than LA proper — does that change AC sizing?
It does. San Gabriel Valley design temperatures run several degrees above the basin, so a system sized for 'LA average' will fall behind here. We size for Pasadena's actual climate.
