⚠️ Factors That Influence Price
1. Home Size and Layout
-
Larger homes require bigger furnaces and may need duct upgrades.
2. Accessibility
-
Crawlspaces, attics, or tight basements increase labor time and cost.
3. Climate Zone
-
Cold regions require higher-capacity units.
4. Fuel Type
-
Gas is often cheaper long-term but may require gas line work.
5. Brand and Model
-
Premium brands or advanced staging (modulating) models increase costs.
🔎 Getting Accurate Quotes
-
Get 3-5 written bids from licensed, insured contractors.
-
Request detailed breakdowns of labor, equipment, permits, and extras.
-
Ask for brand, model numbers, and warranty terms.
-
Verify contractor certifications (NATE, ACCA membership, state licensing).
Use the contractor checklist from Better Business Bureau (BBB).
🎯 How to Save Money Wisely
-
Look for local utility rebates (check Energy Star Rebates Finder).
-
Consider off-season installation discounts (spring and early fall).
-
Bundle furnace replacement with other HVAC work (AC or heat pump upgrade).
-
Avoid cheap unlicensed labor — poor installs often cost more in the long run.
-
Proper sizing is critical: request Manual J load calculations (see ACCA Manual J Guide).
