What does furnace installation cost in St. Louis?
Plan on roughly $4,500–$9,500 for furnace installation in the St. Louis metro. The lower end covers diagnostics and routine fixes; the upper end covers larger jobs where parts and labor stack up. Most St. Louis homeowners we route end up somewhere in the middle.
St. Louis furnace installation pricing tracks closely with metro size and equipment-supplier proximity. Major-metro contractors face higher overhead, but they also have parts on hand more often, which can speed up resolution and reduce the total bill.
One quick honesty test: ask your matched St. Louis contractor for the warranty terms and the line-item breakdown before you sign. Reputable MO pros give you both without flinching. The ones who don't are usually the ones whose final invoice doesn't match the verbal quote.

Furnace Installation FAQ for St. Louis homeowners
How much does furnace installation cost in St. Louis?
A standard 80%-efficient gas furnace install in St. Louis sits at the lower end of the range; a 96%+ AFUE high-efficiency model with new venting pushes higher. Costs vary based on BTU capacity, brand, and whether ductwork or gas-line modifications are needed. Your matched contractor will quote a fixed price after assessing the home.
How long does a new furnace last?
A well-maintained gas furnace typically runs 15–20 years; many in St. Louis make it longer with annual tune-ups. Skipping yearly service is the single biggest predictor of early failure — clogged flame sensors and tired blower motors take years off a system's life.
Is a high-efficiency furnace worth it in St. Louis?
If you have a long heating season in Missouri, almost always. A 96% AFUE furnace uses roughly 15–20% less gas than an 80% AFUE model, and federal tax credits plus utility rebates often offset much of the upgrade cost. Your St. Louis installer can run the payback math during the quote.
Gas, electric, or heat pump — what works best in St. Louis?
Gas furnaces are still the standard in most of Missouri where natural gas is available. Heat pumps are increasingly competitive — especially cold-climate models — and often pair well with backup electric or gas heat. Your St. Louis contractor will compare lifetime operating costs based on local utility rates.
