A heater for a house typically costs $3,500-$12,000 installed, with an average near $7,500 for a standard replacement; high-efficiency equipment, duct repairs, and difficult installations can push the bill higher. The final price depends on system type, home size, fuel, local labor rates, and whether the project replaces an existing unit or adds new ducts.

House heater prices by system and home size
For a typical 1,500- to 2,000-square-foot U.S. home with existing ducts, a standard gas furnace replacement commonly totals $3,000-$7,000. A larger or high-efficiency model, extensive venting work, or premium installation can bring the total to $9,500 or more. An electric furnace is often less expensive to install, but its operating cost may be higher where electricity rates are steep.
Most replacement buyers should budget about $5,500-$9,500 for a commonly installed whole-house heating system. A ducted heat pump usually costs more upfront, at roughly $5,500-$17,000 installed, but provides cooling as well as heating. A geothermal system is a different, higher-cost project, often $20,000-$40,000 or more because of ground-loop excavation or drilling.
Home area is only a starting point; insulation, ceiling height, climate, windows, and air leakage affect the equipment size needed. A 1,200-square-foot, well-insulated home may need a smaller unit than a drafty 1,200-square-foot home in a cold region. Assumptions: existing system replacement, ordinary access, standard equipment, and no major duct or electrical upgrade.
What furnace, heat pump, and ductwork quotes include
Installation estimates typically combine equipment, removal, labor, and smaller project charges. The table shows common portions of an installed price; the numbers vary by system and should not be added as if every job has every charge. Ask each contractor to identify whether the quote includes tax, startup testing, thermostat, and disposal.
| Quote item | Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|---|
| Gas furnace replacement | $1,500-$4,500 | $1,200-$3,000 | $100-$500 | $50-$300 | $100-$400 |
| Electric furnace replacement | $1,000-$3,500 | $1,000-$2,500 | $75-$350 | $50-$250 | $100-$350 |
| Ducted heat pump | $3,000-$10,000 | $1,800-$5,000 | $150-$700 | $75-$400 | $150-$500 |
| Whole-house ductwork | $1,200-$7,000 | $1,000-$4,500 | $100-$500 | $50-$400 | $100-$600 |
The table categories are approximate allocations, not separate guaranteed line items. A quote may bundle labor and equipment setup, while a complicated retrofit may list electrical work or vent materials separately. Labor totals vary with crew size and access. Typical HVAC labor runs about $75-$150 per hour per technician, depending on location and task.
A detailed quote should state the equipment model, capacity, efficiency, labor scope, and exclusions. Check whether the contractor is replacing the thermostat, reconnecting condensate drainage, modifying the flue, testing airflow, and registering the manufacturer warranty. A low bid that omits these tasks can become more expensive after work begins.
How BTUs, efficiency, and ductwork change the estimate
Heating capacity is measured in BTUs per hour, but sizing should come from a load calculation rather than a simple square-foot rule. Common residential furnaces range from about 40,000 to 120,000 BTU per hour. Oversizing can cause short cycling and uneven comfort; undersizing can leave rooms cold during design-weather conditions. A contractor may charge $150-$500 for a standalone load calculation, though it is often included with a replacement proposal.
Efficiency also affects equipment price. A basic gas furnace around 80% AFUE often costs less than a 95%-98% AFUE condensing furnace, which needs compatible venting and condensate drainage. Depending on model and installation, choosing a high-efficiency furnace may add about $500-$2,000. The fuel savings depend on local gas prices, climate, usage, and the old unit’s condition, so higher efficiency is not automatically the lowest lifetime-cost choice.
Duct condition can change the scope substantially. Sealing leaks may cost roughly $300-$1,500, while replacing ducts throughout a home commonly falls around $2,000-$12,000. Restricted returns, undersized ducts, asbestos-containing materials, or access through finished ceilings can increase labor. Heat pumps also require correct airflow and refrigerant-line installation; a mismatched indoor coil or outdoor unit can reduce performance and affect warranty coverage.
Capacity and compatibility matter more than choosing the largest or highest-rated model. For a heat pump, compare the manufacturer’s capacity at cold outdoor temperatures, not only its nominal rating at mild conditions. Some cold-climate installations need supplemental electric resistance heat or a dual-fuel arrangement, which can raise equipment and electrical costs.
Gas furnace or heat pump for the same home
A gas furnace generally has the lower installed price when gas service and usable ducts already exist. Typical replacement pricing is $3,000-$9,500, compared with about $5,500-$17,000 for a ducted air-source heat pump. The heat pump’s price includes both heating and cooling equipment in many configurations, so comparisons should account for whether a separate air conditioner would otherwise be purchased.
Operating costs cannot be predicted from installation price alone. A heat pump can be economical in moderate climates and in homes with favorable electric rates, while a gas furnace may cost less to run in cold regions with low gas prices. Existing electrical service can also matter: a panel or circuit upgrade may add $500-$3,000 or more, especially if the home needs a larger service or substantial wiring work.
Compare installed system totals and estimated annual energy bills, not equipment sticker prices alone. Ask for a side-by-side estimate that uses local utility rates and the home’s expected heating load. Include cooling equipment, backup heat, thermostat, electrical changes, and any required gas-line or vent work in both alternatives.
Regional labor rates and climate shift installed prices
Labor and code requirements create meaningful regional differences. A straightforward furnace replacement may cost about 10%-20% less in a lower-cost rural market than in a major coastal metro, while dense urban locations can run 10%-25% above a national-style estimate because of labor rates, parking, access, and disposal logistics. These percentages are broad comparisons, not fixed surcharges; contractor availability and local equipment supply can move the quote either way.
Climate affects the system selected and its required capacity. Cold northern locations may need a higher-capacity furnace, a heat pump designed for low temperatures, or backup heat. In warmer regions, a smaller heating load may allow lower-capacity equipment, although buyers often install a combined heating and cooling system. Coastal areas may have corrosion concerns, while mountain or rural homes can face higher delivery and travel charges.
Use local bids and local utility rates when comparing prices. Obtain at least three written estimates from contractors who regularly install the chosen system in the area. A quote from another state is not a reliable benchmark if fuel costs, permit fees, labor rates, climate design temperatures, and code requirements differ.
How many hours a heater replacement takes
A basic furnace or heat pump replacement commonly takes one workday, or about 6-10 hours for a two-person crew, if the old equipment, duct connections, electrical service, and venting are compatible. A more involved project can take 2-4 days when the crew must modify ducts, relocate equipment, upgrade wiring, install new refrigerant lines, or coordinate inspections.
Hourly rates are not always shown separately because many HVAC companies quote a fixed installed price. Where labor is itemized, residential technician rates commonly fall around $75-$150 per hour, and a service call or diagnostic visit may cost $75-$250 before repair work. After-hours emergency service can carry a premium, sometimes adding $100-$300 or more to the visit.
Ask how many workers are included and what conditions trigger extra labor charges. Confirm that startup, safety checks, airflow or combustion testing, thermostat setup, and homeowner instructions are part of the scheduled installation. If the quote assumes clear access, moving stored items away from the furnace can prevent avoidable delays.
Removal, permits, and extras that raise the bill
Removing an old furnace is often included in a replacement quote, but disposal may be listed separately at about $100-$400. A new installation can require a permit, commonly $50-$400 depending on the jurisdiction and project type. Some locations require inspection, updated venting, combustion-air provisions, seismic restraints, or electrical disconnects; those items should be priced rather than treated as unexpected extras.
Common additional charges include a new thermostat at $150-$600 installed, condensate pump or drain work at $100-$500, and gas-line changes at roughly $250-$1,000. A new circuit or panel work may cost $500-$3,000 or more. If asbestos abatement, chimney relining, or substantial duct replacement is needed, the contractor should explain the condition and provide a separate scope before proceeding.
Request a written list of exclusions before approving the work. A low base price may not include permit fees, duct modifications, crane or lift rental, disposal, electrical changes, or repair of concealed damage. Local rebates or tax incentives may reduce eligible heat-pump costs, but rules, funding, and qualifying equipment vary; verify current terms with the utility or tax professional before including a discount in the budget.
Where homeowners can trim a heater replacement bill
Keeping a compatible fuel type, location, thermostat, and duct layout usually avoids expensive conversion work. If the existing furnace cabinet and venting can accept a correctly sized standard replacement, comparing like-for-like models can reveal whether premium controls or a higher efficiency tier are worth the added cost. Do not reduce the capacity below the load calculation to save on equipment; poor sizing can create comfort problems and early wear.
Compare at least three itemized estimates with the same capacity range, efficiency level, warranty, and included tasks. Ask contractors to separate required code work from optional upgrades, and confirm whether rebates are already subtracted from the quote. Scheduling a planned replacement during a contractor’s less-busy period may improve availability, though savings are not guaranteed. Emergency replacement during a cold snap can limit choices and increase service charges.
Repair can be less expensive when a relatively new heater has a defined, isolated fault. Common repairs may cost about $150-$1,000, while a major heat exchanger or control-board repair can reach $1,000-$3,000. Compare the repair estimate with the age, condition, remaining warranty, efficiency, and expected service life of the existing unit. Replacing a worn system may make sense when repairs are frequent, but age alone does not establish that replacement is necessary.
The most reliable savings come from controlling scope and comparing equivalent bids. Clear the work area, provide accurate information about past repairs, and ask the contractor to inspect ducts and electrical capacity before finalizing the price. Avoid paying for add-ons that do not solve a documented need, while retaining required safety work, permits, and commissioning checks.
