Furnace Installation in San Antonio, TX | New Furnace Replacement

New furnace installation typically costs $7,000-$10,000 for standard systems. The final price depends on furnace size, efficiency rating (80% vs 95% AFUE), brand, and installation complexity. We provide free in-home estimates with transparent pricing and help you access rebates that can save $1,000-$3,000+. Our 12-year parts and labor warranty is included at no extra cost.

Most residential furnace installations are completed in one day (6-10 hours). Complex installations requiring ductwork modifications, electrical panel upgrades, or gas line work may take 1-2 days. We'll give you an accurate timeline during your free consultation and work efficiently to minimize disruption to your home.

Furnace size depends on your home's square footage, insulation levels, ceiling height, number of windows, and San Antonio's climate zone. Our technicians perform a detailed Manual J load calculation to determine the right size - an oversized or undersized furnace wastes energy and shortens equipment life. We'll recommend the perfect size during your free consultation.

95%+ AFUE high-efficiency furnaces cost $1,500-$3,000 more upfront but save 15-20% on heating bills annually and qualify for larger rebates ($650 vs $350 from CPS Energy). In San Antonio's mild winters, payback period is typically 7-10 years. We'll show you both options with long-term cost comparisons so you can decide what's best for your budget and comfort goals.

Yes, we offer flexible financing with low monthly payments and special 0% APR promotions for qualified buyers. Many customers finance their furnace installation and use monthly energy savings to offset the payment. Learn more about financing options.

CPS Energy offers $350-$650 rebates for high-efficiency furnace systems (95%+ AFUE), and federal tax credits cover up to 30% of equipment costs through 2032 under the Inflation Reduction Act.
