How much does a new furnace cost in Sunnyvale

A new furnace installation in Sunnyvale 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 Sunnyvale 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 Sunnyvale 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 Sunnyvale estimate — we serve all Santa Clara County neighborhoods.

Why Choose Professional Furnace Installation in Sunnyvale?

Choosing the right furnace for your Sunnyvale home means matching system efficiency to your local climate and existing ductwork. Sunnyvale's Silicon Valley location creates warm, dry summers with temperatures regularly reaching 85-95°F, while winters are mild and moderate. This climate makes efficient air conditioning essential for summer comfort. Our certified technicians evaluate your home's insulation, duct condition, and heating load before recommending any system — so you get the right size, not an oversized unit that short-cycles. West Sunnyvale and Cherry Chase homeowners increasingly choose high-efficiency variable-speed furnaces (96%+ AFUE) or hybrid heat pump systems to reduce gas dependence. Galaxy handles all permits and utility paperwork for Santa Clara County.

Sunnyvale homeowners replacing furnaces increasingly face a choice between a like-for-like gas replacement and a step toward a heat pump system. Galaxy installs both and can model the long-term cost comparison for your specific Sunnyvale home. For West Sunnyvale properties with existing gas infrastructure and good ductwork, a high-efficiency gas furnace is often the straightforward right answer. For Cherry Chase homes with solar panels or EV chargers, the heat pump economics frequently favor electrification — and we will show you both numbers.

Looking for Sunnyvale's most trusted HVAC contractor? Galaxy Heating & Air Conditioning is your local expert for air conditioning, heating, and heat pump solutions across all Sunnyvale neighborhoods.
