Why Proper AC Service Matters
Bay Area summers have intensified in recent years, with heat waves regularly pushing past 95°F in the East Bay, South Bay, and inland valleys. Even fog-belt San Francisco sees increasingly hot stretches — making a properly installed and maintained AC system essential, not optional.
A failing or undersized system doesn’t just mean discomfort. It means higher energy bills, shortened equipment life, and reduced home value. Our EPA-certified technicians ensure your system is sized correctly, installed to code, and performing at peak efficiency from day one.

AC Services FAQ
Most central AC installations complete in one day (6–8 hours). Ductless mini-splits take 3–5 hours per zone. Homes needing new ductwork may require an additional day.
Yes. California requires a mechanical permit for new AC installations. Hi-Tech handles all permit applications and inspections on your behalf — included in your quote.
We install all major brands: Carrier, Trane, Lennox, American Standard, Mitsubishi, Daikin, LG, and Fujitsu. We carry no brand commissions — we recommend what's best for your home.
For most Bay Area homes, yes. Heat pumps both cool and heat, qualify for California rebates and federal tax credits (up to 30%), and align with the state's long-term energy goals.
Repair makes sense if the system is under 10 years old and the cost is less than 50% of a new unit. If your AC is 12–15+ years old or uses R-22 refrigerant (phased out), replacement typically delivers better ROI.
