- "Free" replacement estimate$0 — it's a sales visit
- Service call / diagnostic fee$75–$150
- Financing offers$0 down · 0% APR, 12–60 mo
- Seasonal tune-up promo$79–$129
Additional furnace replacement costs to budget for
Only a handful of these will touch your total. Which ones depend on what's already in place and how the crew has to reach it.
| Old furnace removal & disposal | $50 – $330 |
| New ductwork (vs. repair $300–$1,500)Only if ducts are missing or failing | $1,000 – $5,000 |
| Gas line run or upgrade | $250 – $800 |
| Chimney liner (for high-efficiency venting) | $600 – $2,500 |
| Smart thermostat | $150 – $500 |
Typical national add-on ranges; confirm locally during your quote.
What's included
- Removal and disposal of the old unit
- Installation labor and basic ductwork connections
- The furnace unit and burner assembly
- Thermostat connection and system startup/testing
What affects the cost
- Whether a chimney liner or new gas line is required
- Fuel type (gas vs electric) and AFUE efficiency rating
- Condition of existing ductwork and venting
- Heating capacity (BTU) needed for your square footage
Ways to save on furnace replacement in Roswell
- Schedule in the off-season (spring/summer) for better rates
- Look for utility rebates on high-efficiency models
- Get at least 3 quotes — installed prices vary widely
- Right-size the unit; oversizing wastes money and cycles hard
How long does furnace replacement last in Roswell?
Gas furnaces typically last 15–20 years; well-maintained units can reach 30.
An annual tune-up keeps efficiency up and protects the warranty.
Signs you need furnace replacement in Roswell
- The furnace is 15+ years old (near or past its service life)
- Heating bills keep climbing despite no change in usage
- Some rooms are warm while others stay cold (uneven heating)
- Frequent repairs — you've called for service more than once or twice recently
- Banging, rattling or screeching noises on startup
- A yellow or flickering burner flame instead of steady blue (have it checked immediately)
- More dust, dryness, or a stale smell when the heat runs
Repair or replace in Roswell?
Repair if…
- The unit is under ~10 years old and otherwise efficient
- The fix is a single inexpensive part (igniter, flame sensor, capacitor)
- It's still under manufacturer warranty
Replace if…
- It's 15+ years old and needs a major part
- The heat exchanger is cracked (a safety issue — replace, don't repair)
- The repair costs more than about half of a new system
- It's an 80% AFUE unit and your fuel bills are high in a cold climate
Rebates & incentives in Georgia
Most 2026 rebates reward switching to a heat pump, not a like-for-like gas furnace. Replacing a gas furnace, your savings are mainly utility efficiency rebates (high-AFUE models) — but pricing out a heat pump often qualifies you for far larger rebates.
The federal 25C tax credit (up to $2,000 for heat pumps; $600 for high-efficiency AC or furnaces) and the 25D credit ended December 31, 2025 under the One Big Beautiful Bill Act — neither is available for 2026 installs. The remaining federal help is the IRA Home Electrification & Appliance Rebates (HEAR): up to $8,000 toward a heat pump for households under 150% of area median income, paid at point of sale where a state has launched its program.

Cheapest time for furnace replacement in Roswell
Installers cut prices in spring and fall because job volume drops and crews sit idle — the opposite happens during a summer heat wave or winter cold snap, when a dead system forces homeowners into a full-price emergency swap.
Why furnace replacement quotes vary — and how to compare them fairly
One bid high, one low, same house? The variable is scope. Here's what pushes the figure up or down and how to get quotes you can actually compare.
Why a quote looks high (or low)
- Equipment tier isn't matched — a 14.3 SEER2 bid will always undercut an 18 SEER2 one for the "same" job.
- Brand, warranty length and whether startup/commissioning is included all move the number.
- Sizing was guessed from square footage instead of a Manual J load calculation, so the equipment is wrong.
Get an apples-to-apples bid
- Get at least three written bids before you sign.
- Require an itemized quote splitting equipment, labor, permit and add-ons.
- Confirm old-unit removal, the permit and startup testing are all included.
- Insist on a Manual J load calculation, not a square-footage guess.
Questions to ask Roswell HVAC pros
You can't judge bids side by side unless they cover the same ground; run through these with every pro on your list.
- 1Did you run a Manual J load calculation to size the system, or estimate from square footage?
- 2What AFUE/SEER2 rating is this unit, and what's the payback vs. the next tier up?
- 3Is removal of the old equipment, the permit, and startup testing included in the quote?
- 4Will my existing ductwork and venting work as-is, or is repair/resizing needed?
- 5What's covered under the labor warranty vs. the manufacturer's parts warranty?

Budget about $225 for the HVAC permit most Roswell jobs like this require — and note it already sits inside the estimate above, not on top of it.
What affects furnace replacement cost the most?
In plain terms, replacing a residential furnace, including the unit and installation labor. Grade of equipment and materials tops the list, followed by home size and complexity, local labor, and the hot climate zone.
How much should you really budget for HVAC in 2026?
Ask five contractors for an HVAC quote and you'll get five different numbers — usually because they disagree on sizing, efficiency and equipment tier. Here's how our editors think through those trade-offs.
The longevity case
The single biggest cost driver isn't the brand — it's correct sizing and install quality. A properly sized, well-commissioned mid-tier system with annual maintenance outlasts an oversized premium unit that short-cycles. Spend on the install, not the badge.
The efficiency-first case
In a hot-summer or cold-winter region, a higher SEER2/AFUE unit — or a heat pump — earns its premium back in lower bills, and utility and state rebates can still cut into the sticker (the federal 25C/25D credits ended Dec 2025). Run the payback math before defaulting to the cheapest box.
The budget-first case
Size the system to your home with a Manual J calculation and buy the standard efficiency tier (80% AFUE / 14.3 SEER2). In a mild climate the cheaper unit pays off because you rarely run it hard — paying for premium efficiency you won't use is the most common way to overspend.
Match the efficiency tier to your climate, insist on a real load calculation, and stack every rebate you qualify for. The expensive mistakes are wrong sizing and a rushed install — not picking the "wrong" brand.
