From one homeowner to another
Manny was very trustworthy and professional. He gave me a very fair price. Within 24 hours he had done his inspection and given me an estimate. It's the first time I talked to an HVAC company that didn't make me feel like I was getting overcharged. One of the other companies I spoke to was trying to charge 6 times the cost. He took lots of pictures and video and explained step by step what was done wrong by the other contractors and what he would need to do to fix it. He was able to do the work the day after I accepted the estimate. He completed all the work in one day. I am confident and very relieved to say that my HVAC system is set up properly.

How Much Does HVAC Replacement Cost by Unit Type?
The type of HVAC system you choose is the single biggest driver of your overall replacement cost, with options ranging from $150 for a basic window AC unit up to $14,500 for a premium ductless mini-split. Speaking with a local HVAC pro is the best way to get an accurate quote for your specific home. The table below breaks down average HVAC replacement costs based on system type:
| HVAC System Type | Average Cost in 2026 |
|---|---|
| Ductless mini-split | $2,000–$14,500 |
| Window AC unit | $150–$550 |
| Whole-house fan | $900–$3,600 |
| Central air | $3,900–$7,900 |
Ductless Mini-Split AC
Ductless mini-split ACs cost between $2,000 and $14,500, with the wide range driven primarily by how many individual zones you want to cool. Each system pairs an outdoor condenser with one or more indoor units, making them a flexible choice for homes without existing ductwork.
Window AC Unit
Window air conditioning units cost between $150 and $550 on average, including professional installation when needed. Keep in mind that DIY options for window AC installation can reduce that cost, though window units are only practical for individual rooms and small apartments rather than whole-home cooling.
Whole-House Fan
Whole-house fan systems cost between $900 and $2,500 to install, with the final price varying based on where the fan is mounted. Adding advanced options such as multiple fan speeds, shutters, and additional home insulation can push the total up to $3,600.
Central Air Conditioner
The cost of a central AC system ranges from $3,900 to $7,900, depending on your home's size and the amount of ductwork involved. For homes in regions with hot, humid summers, central air offers a meaningful advantage over window or mini-split systems by cooling more quickly and protecting against moisture and mold.
How Much Does Furnace Installation Cost?
Furnace installation costs vary significantly by fuel type, as the breakdown below shows:
| Type of Furnace | Average Cost in 2026 |
|---|---|
| Electric | $1,700–$7,100 |
| Gas | $3,800–$10,000 |
| Oil | $3,800–$10,000 |
Electric Furnace
The price of an electric furnace ranges from $1,700 to $7,100, and if you opt for a forced-air system, budget an additional $500 to $2,000 for new ductwork. Electric furnaces perform best in warm climates, typically climate zones one through three, covering the southern tip of Florida through Central California.
Gas Furnace
The cost of a gas furnace for an average-sized home runs $3,800 to $10,000, not including new ductwork, gas lines, or thermostats. Gas and propane units tend to cost less to operate than electric furnaces in cold climates, making them a practical long-term choice for homeowners in colder regions.
Oil Furnace
Oil furnaces remain a common choice in areas where natural gas and propane lines are unavailable, with total installation costs ranging from $3,800 to $10,000.
How Much Does a Heat Pump Cost?
Heat pump costs depend on the type and energy source, as the breakdown below shows:
| Heat Pump Type | Average Cost in 2026 |
|---|---|
| Heat pump | $4,200–$7,600 |
| Geothermal | $4,500–$24,500 |
| Air source | $4,500–$8,000 |
| Hybrid | $2,500–$10,000 |
| Solar | $18,000–$39,000 |
| Supplement electric | $2,500–$6,000 |
Heat Pump
The cost of heat pump installation ranges from $4,200 to $7,600, depending on the unit's capacity and the amount of ductwork your home requires. Heat pumps perform best in temperate climates but are becoming an increasingly common choice across the country as technology improves.
Geothermal Heat Pump
The price to install a geothermal heat pump ranges from $4,450 to $24,450 upfront, but the energy savings these systems generate can offset that investment within five to 10 years.
Air Source
Ducted air-source heat pumps, the most popular variety, cost between $4,500 and $8,000. Air-source heat pumps work by extracting heat from outdoor air and distributing it indoors during winter, then reversing the process to expel indoor heat outdoors during summer.
Hybrid
Hybrid heat pumps cost between $2,500 and $10,000 and combine a heat pump with a secondary heating source, such as a furnace or boiler. When outdoor temperatures drop below a set threshold, the system automatically switches to the backup heat source, making it a reliable option in climates with occasional extreme cold.
Solar
Pairing solar power with an air-source or ground-source heat pump can deliver substantial long-term savings on your electric bill, but you will need to generate at least 1,500 watts per ton of your heat pump's rating. Reaching that output requires an investment of $18,000 to $39,000 for the cost of solar panels.
Supplemental Electric
Newer heat pump models with a built-in supplemental electric resistance booster heater cost $500 to $1,000 more than standard heat pumps, adding enhanced functionality to dual-fuel hybrid systems. If you want to add a supplemental heat pump to an existing furnace instead, expect to pay between $2,500 and $6,000 for that installation.
How Much Does Boiler Installation Cost?
Boilers work differently from furnaces—they heat water and send steam through radiators and baseboards rather than distributing hot air. Boiler replacement costs average between $3,700 and $8,300, though high-efficiency models can push that figure to $12,000. Costs vary by boiler type, as the breakdown below shows:
| Boiler Type | Description | Average Cost in 2026 |
|---|---|---|
| Oil | Burns oil to produce hot water or steam | $4,800–$9,000 |
| Gas and propane | Burns natural gas or propane to heat water | $2,800–$9,000 |
| Electric | Uses electricity to heat water, easy installation | $1,800–$8,000 |
| Wood | Uses wood logs or pellets to generate hot water or steam | $2,500–$10,000 |
How Much Does HVAC Replacement Cost by Unit Size?
Your HVAC team determines the right unit size based on your home's square footage and local climate, and larger units tend to carry higher price tags. Factors such as your climate zone, home age, insulation type, and number of windows can all affect how many tons or BTUs are needed, so a bigger home does not always require a proportionally larger system.
The table below breaks down the average air conditioner cost based on your home size:
| AC Size | Home Size (Sq. Ft.) | Average AC Cost (Not Including Labor) |
|---|---|---|
| 1.5 tons | 600–1,000 | $2,000 |
| 2.5 tons | 1,000–1,600 | $2,900 |
| 3 tons | 1,600–2,000 | $3,000 |
| 3.5 tons | 2,000–2,500 | $3,500 |
BTUs, or British Thermal Units, describe the furnace’s size/capacity. Here’s how home size influences BTUs and the cost of a furnace:
| Unit Size (BTUs) | Home Size (Sq. Ft.) | Average Furnace Cost (Not Including Labor) |
|---|---|---|
| 40,000–60,000 | 800–1,200 | $2,000–$4,500 |
| 75,000–100,000 | 1,500–2,000 | $2,500–$5,900 |
| 120,000–140,000 | 2,500+ | $4,000–$8,000 |
HVAC Replacement Cost Factors: What Affects the Price?
Beyond system type and unit size, several additional factors can meaningfully shift your total HVAC replacement cost.
Labor and Installation
Labor to install an HVAC unit averages $1,500, covering the work of removing and replacing components and verifying that the system operates correctly. Homeowners who have never had an existing HVAC system, such as those building a new home, should also budget for ductwork: the cost of installing ductwork ranges from $1 to $13 per linear foot, with the average falling around $3,500.
Location of the AC Unit
The cost of replacing your HVAC system can shift depending on where the units are located, as the table below shows:
| Location | Examples | Cost |
|---|---|---|
| Outside of home | Side of home, behind home, roof-mounted | No extra cost |
| Inside of home | Utility closet, attic, basement | $1,000–$2,500 to build |
Efficiency Ratings
The Department of Energy uses ratings such as SEER, AFUE, and HSPF to assign an efficiency score to HVAC equipment, and knowing the required rating for your area is an important first step. Each step up in rating adds $350 to $1,500 to your upfront cost, but the long-term utility savings can make that premium worthwhile. Ask your HVAC pro which efficiency rating makes the most sense for your specific climate before purchasing.
Brand
HVAC brands vary in price, with some known for more energy-efficient models that carry a higher cost, so it pays to shop around before committing to a unit. Regardless of brand, the average cost of an HVAC unit is around $4,750.
How Much Does HVAC Replacement Cost by Project Type?
The scope of your project, whether a straightforward equipment swap or a full installation with new ductwork, has a significant impact on your total cost.
| Project Type | Average Cost in 2026 |
|---|---|
| HVAC Change-Out | $3,300–$16,000 |
| Full HVAC Installation With Ductwork | $8,500–$19,200 |
HVAC Change-Out
A straight HVAC change-out, swapping your existing central AC and furnace for more efficient models, costs $3,300 to $16,000 for the equipment plus about $1,500 for labor. New ductwork is only an added expense if your existing ductwork is in poor condition or you are adding new zones.
Full HVAC Installation With Ductwork
Adding new ductwork to an HVAC installation considerably increases the total cost. HVAC ductwork installation averages $1,000 to $2,700 for a 1,000-square-foot system, bringing the combined total to between $8,500 and $19,200 for a new HVAC system of that size, not including removal fees.
HVAC Replacement Costs: What Other Expenses Should You Budget For?

Beyond location and unit size, several supplemental expenses can add to your total project cost. The table below shows the average cost of additional factors when installing a new HVAC system:
| Additional Cost Factor | Average Cost |
|---|---|
| Permits | $50–$500 |
| New ductwork | $15 per linear foot |
| Insulation | $1,500 |
| Adding zones | $2,000–$3,000 |
| New thermostat | $120–$260 |
| New features | $400–$2,800 |
| Asbestos removal | $1,200–$3,100 |
| Removal and disposal fees | $60–$500 |
Why You Should Hire an HVAC Contractor
Replacing an entire HVAC system requires addressing various aspects, including the type of HVAC equipment, equipment sizing, ductwork, airflow, refrigerants, and more. Choosing the wrong system, installing it incorrectly, or not having the correct components can increase your energy costs and decrease your comfort. Plus, you'll need a license to handle refrigerants. You'll get the safest and best results if you leave this task to a licensed HVAC contractor near you.
Here's why it's ideal to hire an HVAC pro
An HVAC pro can ensure your system operates smoothly and offers the following benefits:
HVAC contractors ensure your furnace, air conditioner, ductwork, and controls are compatible.
They size and match components correctly for your home's needs.
Licensed pros are legally allowed to handle refrigerants.
Installers will verify that your system's controls and thermostats operate correctly.
They can address home comfort questions, such as cold spots, rooms that are not used often, air quality concerns, and ventilation needs.
Many HVAC equipment manufacturers require professional installation to maintain warranty coverage.
They can show you how to change your air filters and maintain your system between tuneups.
Unless you're installing a simple window AC unit, you shouldn't tackle new HVAC installation yourself. You need to have a license to handle refrigerants when installing. Not only that but with any wrong move in the installation process, you're looking at a higher energy bill and a system that can't provide the cool or warm air you're looking for.
You can save between $60 and $300 if you install a window air conditioner. Otherwise, it's always best to call a trained and trusted pro to handle HVAC installation.
Labor will typically cost $1,500, but professional installation provides the peace of mind that your home is safe and comfortable for the years ahead.
Angi Tip
An Angi survey found that pros don’t recommend homeowners attempt their own electrical work, HVAC installation, roofing repairs, plumbing work, or other tasks that require specialized knowledge. In these situations, hiring a pro can prevent costly or dangerous mistakes.
How to Save on HVAC Replacement Costs
