Does furnace replacement cost cost more in Texas?
-5% versus the national baseline
Installed prices in Texas run about 5% below the national baseline. Permit fees are about 5% lower than the national average. Owner-builder permits allowed on owner-occupied property.
Texas has no statewide contractor licensing for general residential work, so verifying trade licenses and insurance matters more here than in almost any other state.
Compare with the national average furnace replacement cost calculator.

What changes the number in Texas

The formula
Cost = base unit cost x efficiency multiplier + venting + removal + permit
High-efficiency condensing furnaces (90%+ AFUE) need new PVC venting and a condensate drain, which is why the jump from 80% to 96% AFUE costs more than the equipment difference alone.
