Heating and cooling units cost about $5,000-$12,000 installed for a typical replacement, with an average near $8,000. The final price depends on system type, home size, efficiency, ductwork, labor rates, and whether the project replaces one unit or a complete heating and cooling system.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Central AC and furnace replacement | $5,000 | $8,000 | $14,000 | Typical 1,500-2,000 sq ft home |
| Heat pump system | $6,000 | $10,000 | $18,000 | Installed, standard ductwork |
| Central air conditioner only | $3,500 | $6,000 | $10,000 | Outdoor condenser and indoor coil |
| Ductless mini-split | $2,500 | $5,500 | $12,000 | One to three indoor zones |
What a typical home HVAC replacement includes
For a standard central system replacement, homeowners commonly pay $5,000-$12,000 for a furnace and air conditioner, including removal of the old equipment and connection to existing ducts. A basic furnace-and-AC pairing may start near $5,000, while larger homes, premium equipment, or duct modifications can bring the total above $14,000.
A complete heat pump replacement typically costs $6,000-$15,000. It provides both heating and cooling, and can cost more when a home needs an electrical upgrade or backup heat. Central AC alone is often $3,500-$10,000, while a single-zone ductless mini-split may run $2,500-$6,000 installed.
For a typical ducted home, budget roughly $8,000 for a standard furnace-and-AC replacement. Per-square-foot pricing is less reliable than a load calculation, but installed central systems often work out to around $4-$8 per sq ft when replacing equipment without extensive duct repairs.
Assumptions: U.S. mid-market labor, standard equipment, existing usable ducts, normal access, and no major electrical or structural work.
How equipment, labor, and removal shape the quote
Quotes combine equipment, installation, and job-specific work. Ask contractors to identify what is included, especially disposal, thermostats, permits, and duct changes. The ranges below describe common portions of a residential replacement and may overlap depending on how a company presents its quote.
| Quote component | Low | Average | High | Typical basis |
|---|---|---|---|---|
| Furnace or air handler | $1,500 | $3,000 | $6,000 | Equipment only |
| AC condenser and coil | $2,000 | $3,500 | $6,500 | Equipment only |
| Installation labor | $1,200 | $2,500 | $5,000 | Standard replacement |
| Removal and disposal | $150 | $350 | $700 | Old equipment |
| Permit and inspection | $50 | $250 | $600 | Local requirements |
Labor can include setting equipment, refrigerant lines, condensate drainage, electrical connections, startup, and testing. A crew may charge roughly $75-$150 per worker-hour, though installed quotes usually bundle labor rather than list every hour separately.
Equipment and labor usually make up most of the bill, while permits and disposal add smaller but quote-dependent charges.
How tonnage, efficiency, and duct condition change pricing
System capacity is a major price driver. A 2-ton AC may suit a smaller, well-insulated home, while a 3-5-ton system may be needed for a larger house or hotter climate. Capacity must follow a professional load calculation; oversizing can raise the purchase price and cause short cycling, while undersizing may leave rooms uncomfortable.
Efficiency also affects upfront cost. A basic central AC system may cost $3,500-$7,000 installed, compared with approximately $6,000-$10,000 for higher-efficiency equipment. For furnaces, a standard-efficiency model may cost less than a 95%+ AFUE unit, which can add roughly $500-$2,000 depending on venting and installation needs.
Duct repairs can add $500-$2,000 for sealing or limited modifications; replacing extensive ductwork may cost $2,000-$7,000 or more. Older homes may also need a new electrical circuit, drain line, refrigerant line set, or flue vent. Each can change the quote substantially.
Capacity, efficiency, and duct condition should be compared together rather than choosing equipment by sticker price alone.
How many hours does HVAC installation take
A straightforward furnace-and-AC swap commonly takes 8-16 hours for a two-person crew, often completed in one workday. A heat pump installation may take 8-20 hours, depending on line-set work, controls, and backup heat. New ductwork, difficult access, or electrical upgrades can extend a project to two or more days.
Complexity matters more than the equipment’s size alone. A furnace in a cramped attic or crawlspace can require additional labor, and a system relocation may involve new piping and wiring. Quotes that appear unusually low may exclude startup testing, refrigerant adjustments, or old-unit removal, so verify the stated scope.
Ask whether the quoted labor includes commissioning and airflow checks, not just connecting the equipment.
Why regional installation prices vary across the U.S.
Labor and local demand create meaningful price differences. Major metro areas and high-cost coastal markets can run about 10%-25% above national mid-market estimates. Smaller towns may be 5%-15% below, although limited contractor availability or long travel distances can erase the savings.
Climate affects equipment selection, too. Homes in cold regions may need a cold-climate heat pump or supplemental furnace, while hot, humid areas may favor a higher-capacity AC and better humidity control. These specifications can add $1,000-$4,000 over a basic equipment package.
Compare quotes from contractors serving the same local market and using similar capacity and efficiency ratings.
Heat pump or furnace and air conditioner comparison
A heat pump typically costs $6,000-$15,000 installed for a ducted home, while a new furnace-and-AC combination often runs $5,000-$14,000. A heat pump handles both heating and cooling in one system, but cold-weather performance, electricity rates, and existing backup heat affect operating costs and equipment choice.
Replacing only a failed AC may cost $3,500-$10,000, but the indoor coil and outdoor unit need to be compatible. Replacing only a furnace commonly costs $2,500-$6,500 installed. If the remaining equipment is near the end of its service life, comparing a full replacement with a partial repair can prevent paying labor twice.
Compare the installed price and expected operating needs, not just the number of components in each system.
When permits, duct repairs, or electrical work add charges
Local permits commonly cost $50-$600, though requirements and inspection fees vary. A new heat pump or high-efficiency furnace may require code-related electrical, venting, or condensate changes. Ask the contractor to list anticipated upgrades separately and explain which are required by code versus optional.
Common extras include a smart thermostat for $150-$500 installed, duct sealing for $500-$2,000, and electrical panel or circuit work for $500-$3,000. Emergency or weekend service can carry a $100-$300 dispatch charge before repair costs. Removal of an old oil tank or asbestos-containing material requires specialized pricing.
Get written approval before add-on work begins, especially when hidden duct or wiring problems are possible.
How to lower the HVAC replacement price without cutting essentials
Request three itemized estimates based on the same load calculation, equipment capacity, efficiency level, warranty, and duct scope. Compare model numbers and labor inclusions rather than relying on a single total. A price difference of several thousand dollars may reflect different equipment or omitted work, not simply a better deal.
Keep usable ducts and lines when they pass inspection, and avoid paying for capacity beyond the home’s calculated needs. Standard efficiency equipment can be a sensible choice when energy prices or ownership plans do not justify a premium model. Scheduling outside peak summer or winter demand may improve contractor availability, though savings are not guaranteed.
Check current utility rebates and local incentives before signing; availability and eligibility depend on location, equipment, and installation date. Do not assume a tax credit applies without confirming current rules. Matching the scope across quotes is the most reliable way to identify genuine savings.
