- Furnace size (BTU) and variable-speed blowers
- Venting changes, especially when a water heater shares the old chimney
- Ductwork and return-air modifications
- Permit and inspection
AFUE tier (80% vs 90%+ condensing adds venting/condensate work), BTU size, single-stage vs two-stage/modulating, flue and gas-line changes, and permit/disposal.

Frequently asked
Is $5,000 a fair price for gas furnace replacement in Mississippi?
Yes. $5,000 is right around what most homeowners in Mississippi pay. Anything from $1,920 to $9,240 is inside the normal range for an HVAC company; above $9,240 it is worth getting a second quote.
Why do quotes for the same job vary so much?
Efficiency: 80% AFUE units are cheaper than 95%+ condensing furnaces, which also need PVC venting and a condensate drain. Furnace size (BTU) and variable-speed blowers. Company overhead matters too: a large company with trucks, dispatchers and a warranty department charges more than a one-person shop, and both can be honest prices.
When should I get a second quote?
Any time a quote lands above $9,240, or when the contractor cannot break it into parts, labor and fees. Ask for the itemized version, ask what would change the price, and confirm licensing and insurance. You can also paste the quote into the free QuoteJury checker for an instant second opinion.
