How much does a new furnace cost in Antioch

A new furnace installation in Antioch and Contra Costa 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.

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.

Why Choose Professional Furnace Installation in Antioch?

Choosing the right furnace for your Antioch home means matching system efficiency to your local climate and existing ductwork. Antioch's inland East County location creates extremely hot summers with temperatures routinely exceeding 95-100°F, while winters are mild and moderate. This intense heat makes powerful, reliable air conditioning absolutely essential for comfortable living. 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. Deer Valley and Lone Tree 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 Contra Costa County.

Antioch 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 Antioch home. For Deer Valley properties with existing gas infrastructure and good ductwork, a high-efficiency gas furnace is often the straightforward right answer. For Lone Tree homes with solar panels or EV chargers, the heat pump economics frequently favor electrification — and we will show you both numbers.

Looking for Antioch's most trusted HVAC contractor? Galaxy Heating & Air Conditioning is your local expert for air conditioning, heating, and heat pump solutions across all Antioch neighborhoods. With reliable brands like American Standard, Carrier, Mitsubishi, and Lennox, we deliver proven comfort even during Antioch's extreme summer heat. Antioch's scorching temperatures demand the most powerful, dependable cooling systems available.

Our NATE-certified technicians specialize in furnace installation throughout Antioch and all of Contra Costa County, delivering customized solutions matched to local conditions.
