Furnace Replacement in San Antonio.
Gas and electric furnace replacement sized to San Antonio's mild winters. Sealed combustion, Texas code compliant.
What Does Furnace Replacement in San Antonio, TX Include?
San Antonio winters are mild, but the indoor furnace blower runs your AC coil all summer — so a tired blower is a cooling performance problem as much as a heating problem. I'm Omar Jacobo, and most of my San Antonio furnace replacements happen in the same appointment as the AC replacement. Combined pricing drops roughly 30% vs. doing them separately.
For gas-service homes (most of Alamo Heights, Olmos Park, Terrell Hills, and older Monte Vista), we install 96% AFUE two-stage or 97%+ modulating gas furnaces on the Stay Frosty and It's A Frosty Life tiers. All new installs use sealed-combustion design, vented per the International Fuel Gas Code as adopted by Texas — critical in older homes where the atmospheric-draft flue has been unsafe for a decade.
For all-electric San Antonio homes (most of Cibolo, Schertz, and outer-1604 builds), I steer you away from electric furnaces entirely. Resistance heat costs roughly 3x more to run than a heat pump for the same output. The Department of Energy has detailed efficiency comparisons worth reading before you spend money on resistance heat.
