A heating and cooling quote can be stressful to open, especially when your system is already acting up. Most homeowners want two things right away: a realistic number and a clear sense of whether that number is fair.
This guide gives you both. You'll see typical prices for each type of job, the factors that push a quote up or down, and a simple test for repair or replacement. ARS®/Rescue Rooter® builds these estimates every day through our professional HVAC installation services, and every one starts with a transparent quote up front. Want to talk through your options?

How Much Does HVAC System Replacement Cost?
According to ARS service data, a complete residential HVAC system replacement typically ranges from about $12,000 to $16,000. Where you land depends on system type, home size, and installation requirements. Furnace-only jobs run lower, while premium high-efficiency systems and complex installs run higher.
These figures come from more than 3,000 ARS system installations completed between January 2025 and January 2026. They're approximate ranges, not fixed prices, and your quote will vary by market, equipment, and home.
You may see lower numbers on national cost sites. Those ranges often cover a simple equipment swap. They may leave out ductwork, electrical updates, permits, or a matched indoor and outdoor system.
What a Replacement Quote Should Include
A fair quote spells out every part of the job, so you can compare contractors line by line. A full-service replacement typically includes:
- Evaluation and load calculation: A load calculation estimates how much heating and cooling your home actually needs.
- Old equipment removal: The old unit is disconnected and hauled away, and its refrigerant is recovered.
- Line set updates: The line set is the pair of copper pipes that carries refrigerant between the indoor and outdoor units. It may need cleaning or replacing.
- Electrical work: Wiring, breakers, and the outdoor disconnect switch are checked and updated as needed.
- Installation and charging: The new system is set, connected, and charged with the correct amount of refrigerant.
- Thermostat setup and testing: The thermostat is programmed, and the whole system is tested for airflow and performance.
- Permits: Many cities and counties require a permit and inspection.
If a quote leaves out one of these items, ask why. Missing line items can turn into surprise charges later.
HVAC Replacement Cost by Job
Not every replacement involves your whole system. The table below shows typical ARS ranges for the most common jobs, so you can find the one that matches your home.
| Job | Typical ARS Range | When It Applies |
|---|---|---|
| Full HVAC system replacement | About $12,000–$16,000 | Your heating and cooling equipment both need replacing |
| Gas furnace and AC together | About $13,000–$16,000 | A gas furnace and central AC are replaced as a matched pair |
| Central AC replacement | About $13,000–$16,000 | Your cooling system is failing, and your furnace still has life left |
| Heat pump system | About $12,000–$15,000 | One system handles both heating and cooling |
| Furnace only | About $6,500–$9,000 | Your furnace needs replacing, and your AC is in good shape |
| Ductwork repair or replacement | About $2,800–$4,000 per job | Your ducts are damaged, leaky, or the wrong size |
Source: ARS national service data, January 2025–January 2026. Ranges vary by system type, home size, market, and scope of work.
A heat pump is a single system that moves heat into your home in winter and out of your home in summer. It can replace both a furnace and an air conditioner in the right climate.
Full System vs. AC-Only or Furnace-Only
Replacing both systems at once lets you match the indoor and outdoor equipment so they're designed to work together. It also lines up your warranties and handles the disruption in one visit.
A single-system job costs less upfront. It may make sense when one piece of equipment is much newer than the other. For a closer look at each job, see our AC replacement cost guide or our furnace replacement cost breakdown.
HVAC Replacement Price Factors
Two quotes for the same home can come in thousands of dollars apart, and that's typically not because one contractor is overcharging. According to ARS, the main drivers are equipment tier, efficiency rating, install complexity, and whether extra work like ductwork or electrical upgrades is included.
| Factor | What It Means | How It Affects Cost |
|---|---|---|
| System size | Cooling capacity is measured in tons, and heating capacity in BTUs (British thermal units) | Usually the biggest driver, since larger systems cost more |
| Efficiency rating | SEER2 rates cooling efficiency, and AFUE rates furnace efficiency | Higher ratings cost more upfront but may help lower monthly bills |
| Ductwork condition | Whether your ducts are sealed, sized correctly, and in good shape | Repairs typically add about $2,800–$4,000 per job (ARS data) |
| Electrical needs | Whether your wiring and panel can power the new equipment | An electrical panel upgrade or new wiring raises the total |
| Refrigerant type | New systems use lower-impact refrigerants | Shapes which equipment your contractor can offer |
| Installation access | How easy it is to reach attics, crawl spaces, closets, or rooftops | Tight spaces may add labor time |
| Permits | Local approval and inspection | Adds a fee that varies by city or county |
| Timing | Replacing on your schedule vs. right after a breakdown | Emergency or peak-season jobs may limit your options |
| Location | Local labor rates and climate | Prices tend to run higher in high-cost areas |
Efficiency is worth a close look, because heating and cooling is a big part of your energy use. According to ENERGY STAR heating and cooling guidance, "Nearly half of the energy used in your home goes to heating and cooling."
System Size and Load Calculation
Bigger isn't always better. An oversized system may turn on and off too often, wearing out parts and wasting energy. An undersized system may run nonstop and still leave rooms uncomfortable.
That's why a load calculation matters. It looks at your square footage, layout, insulation, and windows, so you pay only for the capacity your home needs.
Ductwork Condition
Your ducts carry heated and cooled air to every room, so their condition affects both comfort and cost. ENERGY STAR duct sealing guidance notes that "about 20 to 30 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts" in a typical house.
If your ducts are in good shape, you may avoid this cost entirely. If they're not, our ductwork repair and installation work typically runs about $2,800 to $4,000 per job, based on ARS data.
Refrigerant Rules
Refrigerant is the fluid your system uses to move heat. Under the EPA HFC restrictions by sector, new residential air conditioners and heat pumps must use refrigerant below a 700 global warming potential (GWP) limit. GWP measures how much heat a gas traps in the atmosphere.
Older R-410A equipment still has a path forward. The EPA lists "No installation compliance date for systems where all specified components were manufactured or imported prior to January 1, 2025." According to ARS, though, the refrigerant transition is expected to push repair and replacement costs on older R-410A systems higher over the next several years as supply tightens.
Should You Repair or Replace Your HVAC System?
A breakdown doesn't automatically mean you need a new system. ARS recommends a simple rule: if a repair quote is more than half the cost of a new system and your unit is over 10 years old, replacement usually makes more financial sense over the life of the system.
Many homeowners also use the $5,000 rule, a common industry rule of thumb. Multiply your system's age by the repair cost. If the result tops $5,000, replacement deserves a look. For example, a nine-year-old AC needing a $600 repair scores $5,400.
Age matters, too. As a general recommendation, ARS suggests planning to replace air conditioners and furnaces every 8 to 10 years and heat pumps every 8 years. These timelines vary with usage, climate, maintenance history, and installation quality.
| Repair May Make Sense If... | Replacement May Make Sense If... |
|---|---|
| Your system is well short of the recommended replacement window | Your system is in or past the recommended window |
| The fix is small and one-time | Repairs are major or keep coming back |
| The repair costs well under half the price of a new system | The repair costs more than half the price of a new system |
| Your comfort and energy bills are steady | Bills keep rising, or some rooms never feel right |
Watch for these signs:
- Rising bills: Your energy costs climb even though your habits haven't changed.
- Short cycling: The system turns on and off every few minutes without finishing a cycle.
- Odd noises: Grinding, banging, or squealing may point to worn parts.
- Unusual smells: Musty or burning odors may signal mold or overheating parts.
- Uneven temperatures: Some rooms stay warm while others feel cold.
Check these first:
- Make sure the thermostat is set to the right mode and temperature.
- Replace a dirty air filter. We generally recommend changing filters every three months.
- Check whether the HVAC breaker has tripped.
- Clear leaves and debris away from the outdoor unit.
If you smell burning, turn the system off and call a professional. For a deeper look, read our guide to deciding between repair and replacement.
Tax Credits and Rebates in 2026
Some cost guides still mention a federal tax credit for a new HVAC system, but that credit has ended for new installs. The IRS home improvement credit page states, "You can claim the credit for improvements made through December 31, 2025." That means the federal 25C credit won't lower the cost of a system installed in 2026.
Savings may still be available closer to home. Through the DOE Home Energy Rebates program, households "can save up to $8,000* on home upgrades based on modeled energy savings levels with a minimum savings of 20%." These rebates are run by individual states, so amounts and availability vary. Check with your state energy office and your utility, and ask your contractor which incentives apply. A tax professional can confirm what applies to you.
Ways to Manage Your Replacement Cost
A new system is a big purchase, but a little planning may help keep your HVAC system replacement cost manageable.
- Plan ahead: If your system is nearing the recommended replacement window, start budgeting and gathering quotes before it fails.
- Plan off-season: Spring and fall are often easier times to schedule than the peak of summer or winter.
- Compare itemized quotes: Use these questions to ask before replacing so you can compare contractors on the same scope of work.
- Right-size the system: Ask for a load calculation instead of paying for capacity you don't need.
- Ask about financing: Learn how to finance an HVAC system so you can spread the cost over time.
- Protect your investment: The Pro Service Plan includes two HVAC preventive maintenance visits per year, which may help your new system run efficiently.
