Installing a New AC and Heating System

A significant investment in your comfort, energy efficiency, and long-term home value, when you’re replacing an outdated system or outfitting a new build, the cost can vary dramatically depending on several factors. From system type to installation complexity and even geographic location, numerous variables influence the process. This blog will break down what you need to know before committing so you can make a confident and informed decision.

How Much is it to Install AC and Heating in a Standard Home?

The average cost to install both AC and heating in a typical U.S. home ranges from $7,000 to $14,000, but this price isn’t one-size-fits-all. The final number depends heavily on the type of system chosen, home square footage, ductwork needs, and labor rates.

System Type Makes a Big Difference

A central air system with a gas furnace typically falls into one cost range, while a heat pump or ductless mini-split setup falls into another. Central air with a furnace is the most common combination in colder regions, while heat pumps dominate in milder climates. Ductless mini-splits are often preferred for smaller spaces or homes without ductwork.

Home Size and Layout Impact Costs

The larger your home, the more powerful the HVAC system needs to be. Bigger systems come with higher equipment and labor costs. Additionally, homes with multiple levels, high ceilings, or unusual layouts may require more intricate installation methods, which can add to the overall expenses.

Install AC and Heating With or Without Ductwork?

One of the most significant cost factors in HVAC installation is whether your home already has existing ductwork. Retrofitting ducts into a house that doesn’t have them can cost an additional $3,000 to $10,000, depending on complexity.

Ductwork Installation or Replacement Costs

If ducts are already in place but old, leaky, or improperly sized, they may need to be repaired or replaced. New duct installation typically costs between $35 and $55 per linear foot so that the total can add up quickly in large homes.

Ductless Systems Offer Flexibility

Installing ductless mini-split systems can avoid the need for ductwork altogether, making them ideal for older homes, garages, attics, or new additions. While the initial unit cost may be higher, the installation savings and energy efficiency often offset it over time.

How Much is it to Install AC and Heating by System Type?

Different HVAC system types come with different upfront costs and installation fees. Here’s a breakdown of the most common systems:

Central Air With Furnace

A traditional HVAC setup with a split-system air conditioner and a gas furnace typically costs between $7,000 and $12,000 for a complete replacement or new installation, including labor.

Heat Pump Systems

Heat pumps, which provide both heating and cooling, cost between $8,000 to $15,000, depending on brand, efficiency rating, and home size. Dual-fuel systems (heat pump + furnace backup) can operate even more efficiently.

Ductless Mini-Splits

For homes without ductwork, a mini-split system typically costs between $3,000 and $5,000 per zone. A whole-home setup with three to five zones typically costs between $10,000 and $20,000.

AC and Heating Installation Costs by SEER and AFUE Ratings

HVAC systems are rated by their efficiency, measured by SEER for cooling and AFUE for heating. Higher-efficiency systems may cost more upfront, but they lead to lower monthly energy bills and can qualify for rebates.

What is SEER?

SEER (Seasonal Energy Efficiency Ratio) rates the efficiency of cooling systems. A higher SEER means better efficiency. A basic 14-SEER unit will cost less than a high-performance 20-SEER unit, but the latter can save thousands over its lifespan.

What is AFUE?

AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts fuel into heat. A standard 80% AFUE furnace is cheaper, but a 95%+ AFUE model can dramatically reduce energy waste in colder climates.

Upfront vs. Long-Term Value

Opting for a high-efficiency system may increase your installation cost by $1,000 to $3,000, but government rebates and lower utility bills often make it a smarter long-term investment.

How Much is it to Install AC and Heating With Zoning or Smart Features?

Modern HVAC technology offers upgrades that improve comfort and efficiency—though they come with added costs.

Zoning Systems

Zoning allows different areas of your home to be controlled independently. Adding zoning costs around $2,000 to $3,500 but can reduce energy waste and increase comfort in multi-story homes.

Smart Thermostats

Smart thermostats, such as Nest or Ecobee, typically cost between $150 and $400, and many HVAC companies include installation with the purchase of your system upgrade. These devices learn your schedule, optimize energy use, and can be integrated with home automation systems.

Air Purification Add-Ons

Air quality upgrades, such as HEPA filters, UV lights, or whole-house dehumidifiers, can cost between $300 and $1,500, depending on the complexity and system compatibility.

What Do Labor and Permits Add to the Cost of AC and Heating Installation?

Labor makes up 30% to 50% of the total installation price. Most HVAC contractors charge between $75 and $150 per hour, and complete installations can take one to three days, depending on the complexity of the system.

Permit and Inspection Fees

Most municipalities require permits for HVAC installations. Permit costs range from $200 to $1,500, depending on your location and project size. Inspections ensure compliance with local building and energy codes.

Contractor Reputation and Warranty

Hiring a licensed and insured HVAC professional may cost more upfront, but it reduces the risk of improper installation and potential issues. Look for companies offering five to ten-year labor warranties alongside manufacturer equipment warranties.

AC and Heating Installations: Regional Price Variations

Where you live significantly influences the cost of installing an HVAC system. Labor rates, climate needs, and even utility company incentives vary by state.

High-Cost Regions

In areas such as California, New York, or parts of the Pacific Northwest, expect HVAC installation costs to be 20% to 35% higher due to increased labor and permit fees.

Low-Cost Regions

Southern and Midwestern states typically have lower installation prices. However, local climate demands (hot summers or cold winters) may prompt homeowners to invest in more powerful systems, which can impact the final price.

Install AC and Heating As Part of a Remodel or New Construction

Installing AC and heating during a remodel or new build is often less expensive per square foot than retrofitting an existing system. Builders can plan ductwork and unit placement more efficiently.

New Construction Advantage

HVAC installation during new construction typically costs $1,500 to $3,000 less than retrofits, thanks to easier access and streamlined labor. If you’re building from the ground up, take this opportunity to design for energy efficiency from day one.

Renovation Challenges

When adding HVAC during a remodel, contractors may need to open walls or ceilings, reroute electrical, or make room for ductwork. These modifications add time and cost to the project.

How Much is it to Install AC and Heating When Replacing an Old System?

If you already have an HVAC system and are replacing it, you may be able to reuse ductwork, thermostats, and wiring—reducing total costs by $1,000 to $4,000, depending on what’s salvageable.

Full Replacement vs. Partial Upgrades

Sometimes, only one part of the system (AC unit or furnace) needs replacing. This partial upgrade can reduce costs by half, although mismatched systems may lose efficiency if they are not compatible.

Disposal Fees and Cleanup

Most contractors include the removal of old equipment and site cleanup in their estimates, but not all. Be sure to confirm whether these fees—typically $100 to $300—are covered in your quote.

Financing Options for AC and Heating Installation

Because HVAC systems can be expensive, many companies offer financing or payment plans to make installation more affordable.

HVAC Financing Programs

Some HVAC brands offer 0% interest for up to 24 months on new installations. Third-party financing may also be available through lenders, with terms ranging from three to ten years.

Government Incentives and Rebates

Federal, state, and utility company rebates can reduce your costs by $500 to $2,000, depending on the unit’s efficiency and your location. Energy Star-certified systems often qualify.
