In this guide, we will break down what homeowners with homes between 1500 and 2500 square feet can expect to pay. We'll also explain how system type, installation labor, and efficiency levels all contribute to the final price tag.

What Affects the HVAC System Cost for Medium to Large Homes?

The cost of a central air and heating system in 2025 for homes between 1500 to 2500 square feet usually ranges from $9,000 to $18,000 or more. This cost includes the furnace, air conditioner, ductwork modifications (if needed), thermostat, and labor.

Several key elements impact the total cost:

  • Size of your home: A 2500 sq ft home requires a more powerful HVAC system than a 1500 sq ft one.

  • System type: Split systems, ductless mini-splits, and hybrid models all come at different price points.

  • SEER rating and energy efficiency: Higher-efficiency units have higher upfront costs.

  • Labor and installation conditions: Accessibility, existing ductwork condition, and local labor costs influence the labor cost to install HVAC.

  • Location: For example, HVAC installation cost Murrieta CA may differ slightly from HVAC system cost Temecula CA due to local codes, permit costs, and market conditions.

High-Efficiency HVAC System Cost

A growing number of homeowners are choosing systems with higher Seasonal Energy Efficiency Ratios (SEER). These are known as high-efficiency systems. While the high-efficiency HVAC system cost is more up front, it can save you significantly in monthly utility bills.

For homes within the 1500–2500 sq ft range:

  • Expect to pay $12,000–$20,000 for a high-efficiency system.

  • SEER ratings of 18–21 are common.

  • Savings of 20–40% on energy bills are possible over standard systems.

The long-term benefit often outweighs the cost, especially in areas with hot summers or cold winters.

New Furnace and AC Combo Cost 2025

Many homeowners opt for a complete upgrade by replacing both heating and cooling components at the same time. The new furnace and AC combo cost 2025 depends on equipment size and brand quality.

A new combo for a mid-size home might include:

  • A gas furnace (80,000 to 100,000 BTU)

  • A central air conditioning unit (3.5 to 5 tons)

  • Programmable thermostat and improved ductwork

New furnace and AC combo cost 2025 typically ranges from $10,000 to $18,500 including labor and equipment. Brands, warranties, and added features like zoning systems can increase the price.

Labor Cost to Install HVAC in 2025

One of the biggest line items is the labor cost to install HVAC. Installation requires trained professionals to size, install, test, and balance your system properly. Labor is generally 30% to 40% of the total HVAC replacement cost.

  • Standard install: $3,500–$6,000

  • Complex install with ductwork modifications: $6,000–$9,000

In specific locations, HVAC installation cost Murrieta CA can be affected by seasonal demand and city regulations, while HVAC system cost Temecula CA may fluctuate based on housing type or older system replacements.

HVAC Installation Cost Based on Home Size

  • 1500 sq ft: $8,500–$12,000

  • 1800 sq ft: $9,000–$13,500

  • 2000 sq ft: $10,000–$15,000

  • 2500 sq ft: $11,500–$18,000

These ranges assume standard systems and installation. Larger homes need bigger units and more labor, especially when new ductwork or zoning is involved.

In areas like Murrieta and Temecula:

  • HVAC installation cost Murrieta CA often includes permit fees and Title 24 testing.

  • HVAC system cost Temecula CA may include costs for energy compliance and city inspections.

Ways to Save on HVAC Replacement in 2025

There are several methods homeowners can use to lower the overall cost:

  • Rebates & Tax Credits: Look for utility rebates and federal tax credits for ENERGY STAR systems.

  • Off-Season Installation: Winter and early spring may offer discounts.

  • Proper System Sizing: Avoid overpaying by matching system size to your actual home size.

  • Upgrade Thermostat: Smart thermostats help reduce monthly energy bills.

These options not only cut up-front costs but also ensure lower utility bills in the long run.

How to Get an Accurate HVAC Quote

Every home is unique, which is why a professional quote is essential. HVAC professionals consider multiple factors like:

  • Ductwork layout and condition

  • Current insulation levels

  • Energy usage history

  • Number of rooms and windows

It’s always recommended to get at least 2–3 quotes to compare options. Be sure each quote breaks down parts, labor, and warranty details.
