Replacing a gas furnace and air conditioning (AC) unit involves various factors influencing the total cost, from equipment size to installation complexity. Homeowners in the US often seek detailed and accurate information on expenses to budget effectively. This article covers average costs, key variables, and tips to get the best value for a furnace and AC replacement project.
| Component | Average Cost Range | Notes |
|---|---|---|
| Gas Furnace | $1,500 – $5,000 | Depends on efficiency rating (AFUE), brand, and capacity |
| AC Unit | $2,000 – $7,000 | Cost varies with SEER rating, size, and type (split, packaged) |
| Installation | $1,000 – $3,000 | Installation complexity affects labor costs |
| Total Replacement Cost | $4,500 – $15,000 | Includes equipment and installation for both systems |
Factors Influencing The Cost Of Replacing Gas Furnace And AC Unit
Accurately estimating the cost to replace a gas furnace and AC unit requires understanding several key factors. Equipment size and capacity are critical to efficiency and comfort but directly impact price. Larger homes generally require bigger and more powerful systems.
Efficiency ratings such as AFUE for furnaces and SEER for AC units greatly affect purchase and operating costs. Higher-efficiency models tend to have higher upfront costs but reduce energy bills significantly. Brand reputation and warranty coverage also influence pricing, with premium manufacturers charging more for advanced features and extended guarantees.
Installation complexity varies by home layout and existing ductwork condition. Homes with outdated or damaged ducts will incur added repair or replacement fees. The geographic location affects labor rates and permit costs, while seasonal demand might raise prices during peak periods.
Average Costs For Gas Furnace Replacement
Gas furnaces vary widely in price, based on efficiency and size. Basic models with AFUE ratings around 80% typically cost between $1,500 and $2,500. Mid-tier furnaces with efficiencies between 90%-95% range from $2,500 to $4,000. High-efficiency models, 95% AFUE or higher, may be priced from $3,500 to over $5,000.
The furnace capacity, measured in British Thermal Units (BTUs), is sized to your home’s heating requirements. A typical American home ranging from 1,500 to 2,500 square feet usually needs a furnace rated between 60,000 and 100,000 BTUs.
Installation labor generally costs an additional $1,000 to $2,000 depending on complexity. Removing an old furnace, connecting gas lines, and ensuring proper venting increase time and material needs.

Average Costs For Air Conditioner Replacement
Replacing an AC unit involves selecting appropriate size and efficiency. Homeowners should aim for SEER (Seasonal Energy Efficiency Ratio) ratings of 14 or greater, as older units typically fall below this threshold. Entry-level AC units cost between $2,000 and $3,500, suitable for smaller homes or moderate climates.
Mid-range systems with SEER ratings between 16 and 18 cost around $3,500 to $5,000, providing better energy savings and comfort control. High-end units with SEER above 20 feature advanced inverter technology and sound reduction, costing $5,000 to $7,000 or more.
Installation labor adds $800 to $2,000, influenced by difficulty updating refrigerant lines, electrical wiring, and ductwork adjustments.
Installation Considerations And Additional Costs
Beyond equipment prices, installation represents a significant portion of total costs. Qualified HVAC professionals must handle gas connections, refrigerant charging, and system testing to meet safety and efficiency standards.
Additional expenses may include:
- Ductwork repair or replacement: Aging or leaky ducts can reduce efficiency and require sealing or upgrades.
- Thermostat upgrade: Installing a programmable or smart thermostat improves control and energy savings.
- Permits and inspections: Local jurisdictions often mandate permits and professional inspections.
- Removal and disposal: Proper disposal of old furnace and AC units incurs fees.
These factors can add $500 to $3,000 to the project cost.

- Compare multiple quotes: Obtaining estimates from several licensed HVAC contractors helps identify competitive pricing and better service.
- Choose high-efficiency models wisely: Higher initial costs often pay off through energy bill savings over time.
- Consider bundled installation: Replacing furnace and AC simultaneously often lowers labor costs and allows for system compatibility.
- Look for rebates and incentives: Many utility companies and government programs offer rebates for energy-efficient HVAC equipment.
- Maintain existing ductwork: Repairing instead of replacing duct systems lowers additional costs.
Signs Indicating It’s Time To Replace Your Furnace And AC Unit
Understanding when to replace heating and cooling systems helps avoid costly breakdowns and rising energy bills. Common indicators include:
- Frequent repairs and escalating service costs
- Uneven heating or cooling in different rooms
- Age of units exceeding 15-20 years
- Unusually high utility bills without usage changes
- Loud noises or strange odors from the units
Replacing outdated or inefficient systems improves comfort, safety, and reduces environmental impact.
