How Much Does Furnace and AC Replacement Cost in Houston, TX? [2026 Data]

The average cost to replace a furnace and AC system in Houston, TX, is $7,395, and most residents pay between $4,930 and $12,325 for materials and labor. Your costs can vary due to many factors, the most important of which are the size and type of the system. 

Your costs can climb much higher if you need additional ductwork repairs, alterations, or installations. Let’s review how to budget for the cost of replacing a furnace and AC in your Houston, TX home.

Furnace and AC Replacement Cost Factors

Some HVAC replacement projects in Houston, TX, cost as low as $2,465, but prices can climb up to $14,790 or beyond. You’ll need to consider all of the following factors to get an accurate estimate for your installation.

Type of HVAC System

There are four main types of HVAC systems, including split systems, duct-free systems, also called mini-splits, hybrid systems, and packaged heating and air systems. The typical cost ranges for each of these systems in Houston, TX, are as follows:

• Split systems: $3,750–$7,400

• Duct-free systems: $1,975–$14,300

• Hybrid systems: $2,450–$9,850

• Packaged heating and air systems: $9,850–$13,800

Split systems are the most common in Houston, TX, although the mild winters in the area are pushing some residents to consider hybrid systems. That option uses a heat pump as an alternative source of heat to reduce fossil fuel consumption while still providing ample cooling through the long, hot summers. Consider upgrading to a hybrid system, as you’ll see a longer furnace lifespan, better efficiency, and savings on utility bills over time.

Unit Size

The square footage of your house, in part, determines what size furnace and air conditioner you need to heat or cool your space efficiently. You can use home square footage to estimate system capacity, but you need a local HVAC company to help you determine what size you need exactly by doing a load calculation.

Estimate what your HVAC system replacement will cost by comparing your home size to the average in the area, as system capacity and cost scale with home size. The average home in Houston, TX, is just under 2,100 square feet, so expect above-average pricing if your home is larger or below-average pricing if it’s much smaller.

Unit Brand

HVAC equipment costs an average of $4,700, but the brand you buy can affect this number. For example, brands like Amana or Coleman come in closer to the lower end of the spectrum at $2,950, while brands Trane and York can reach up to $5,900 or more. Keep in mind that these prices are just for equipment, and labor costs will still have a major impact on your total.

HVAC Pro Costs

Labor accounts for between 40% and 60% of your total HVAC replacement cost, so you can expect to pay an average of between $2,950 and $4,400 for labor when you hire an HVAC company in Houston, TX. That rate is a bit lower than you’d pay in most other major cities, as Houston’s cost of living is 5% below the national average.

Permits

Your HVAC company will also charge you for permits, which the local building department requires for major HVAC work. The City of Houston charges 2% of the project valuation, plus a flat fee of $47, putting the average total permit fee at $194.90. Don’t forget to budget for this fee separately.

Does Replacing Your AC and Furnace Increase Home Value?

Replacing your HVAC system will provide a bump in property value, especially in an area like Houston, TX, where cooling is a necessity for safety and comfort. On average, a new HVAC installation will provide a return on investment (ROI) of 30%. You can maximize your ROI by choosing a high-efficiency system that will help reduce utility bills through the hot Texas summers, and by opting for a hybrid system that can also help improve comfort and savings.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
