Why Heating Maintenance Matters
Bay Area winters are mild compared to the rest of the country — but a heating system that fails on a cold January night in Berkeley or an inland valley frost is still a real problem. And an inefficient or unsafe system is costly year-round.
Whether you’re replacing an aging gas furnace, upgrading to a high-efficiency heat pump, or just need a repair, Hi-Tech HVAC brings 20+ years of Bay Area experience to every job. We’re honest about what you need — and what you don’t.

Heating Services FAQ
For most Bay Area homes, a high-efficiency heat pump is the best long-term choice. It heats and cools, qualifies for California rebates and federal tax credits, and aligns with the state's gas appliance phase-out. We'll model both heat pump and furnace options for your specific home.
Repair makes sense if your furnace is under 12 years old and the cost is less than 50% of replacement. Signs it's time to replace: 15–20+ years old, yellow pilot flame, frequent cycling, rising gas bills, or R-22 refrigerant.
Yes. Modern cold-climate heat pumps operate efficiently down to 0°F. Bay Area winters rarely drop below 30°F — making heat pumps 2–3x more efficient than gas heating in our climate.
Most furnace replacements complete in 4–6 hours. Full heat pump system installations take 6–10 hours. Homes needing new ductwork or gas line modifications may need an additional day.
Warning signs: yellow or orange furnace flame (should be blue), soot marks near the unit, excessive condensation, and symptoms like headaches or nausea at home. Install CO detectors on every floor if you haven't already.
