How much does a new furnace cost in Los Altos

A new furnace installation in Los Altos and Santa Clara County typically ranges from $4,500 to $12,000 depending on efficiency level, brand, and installation complexity. High-efficiency models (95%+ AFUE) cost more upfront but save significantly on energy bills.

What size furnace do I need for my home?

Furnace sizing depends on your home's square footage, insulation, windows, and local climate. We perform Manual J load calculations to determine the exact BTU capacity needed. Oversized or undersized furnaces waste energy and reduce comfort. Call (925) 578-3379 for a free Los Altos estimate — we serve all Santa Clara County neighborhoods.

How long does furnace installation take?

Most furnace replacements are completed in one day (4-8 hours). New installations requiring ductwork modifications may take 1-2 days. We schedule installations at your convenience and clean up completely. Call (925) 578-3379 for a free Los Altos estimate — we serve all Santa Clara County neighborhoods.

What rebates are available for new furnaces?

High-efficiency furnaces may qualify for utility rebates through PG&E or local utilities. We help you identify and apply for all available rebates to maximize your savings. Call (925) 578-3379 for a free Los Altos estimate — we serve all Santa Clara County neighborhoods.
