The temperatures aren’t the only thing that’s higher in Phoenix—the cost of living is, too. Homeowners can expect to pay more than the national average to hire a local HVAC pro to replace the furnace and AC system. Let’s review the factors that determine the cost of replacing your furnace and AC in your Phoenix, AZ home so you can budget accordingly.

Furnace and AC Replacement Cost Factors 

Furnace and AC replacement costs in Phoenix, AZ vary drastically depending on the type of system, brand, and the size of your home. It’s best to consult an experienced HVAC technician when deciding which system is ideal for your Phoenix home.

Type of HVAC System

There are four types of HVAC systems, including split systems, duct-free systems, hybrid systems, and packaged heating and air systems. Split systems are the most common HVAC systems in Phoenix homes due to their durability and efficiency. Duct-free systems are gaining popularity in homes without existing ductwork. While most HVAC systems can last 15 to 20 years, the intense heat in Phoenix can reduce an HVAC’s lifespan to 8 to 12 years, depending on usage.

The typical cost ranges for each are:

Unit Size

The square footage of your house will determine what size furnace and air conditioner you need to heat or cool your space efficiently. A local HVAC company can help you determine what size you need exactly by doing a load calculation.

Unit Brand

An HVAC system costs about $4,900 on average, but the brand you buy can change this number. For example, brands like Amana or Coleman tend to come in the lower end of the spectrum at $3,100, while brands Trane and York are often $6,200 or more.

HVAC Pro Costs

Hiring an HVAC technician in Phoenix, AZ can cost between $80 to $150 per hour, or between $1,500 to $4,000 on average. The price will depend on the pro’s experience, the type of AC and furnace system, and the complexity of the job. However, it’s worth the cost to hire an experienced pro because they will ensure the  HVAC installation is done safely, and most pros warranty their work and materials.

Permits

Replacing the furnace and AC will typically require a permit from the city of Phoenix. A permit can cost between $150 and $230 or more, depending on the total project price. Confirm with the HVAC technician that they will obtain all necessary permits for the job.

Taxes

Phoenix has a  9.1% combined tax rate for the state, county, and city, which will add to the cost of materials and equipment. For example, if the total for the HVAC system is $5,000, you will pay an additional $455 in taxes. 

It’s key to ensure the pro lists labor separately from the cost of materials to avoid being taxed on labor. Speak with the pro when getting an estimate to understand what you will owe for taxes.

Does Replacing Your AC and Furnace Increase Home Value?

A new HVAC system can raise your home’s value by 5% to 7%, with a 30% return on investment. Replacing the AC and furnace in your Phoenix home will make it more appealing to potential buyers, as they can avoid costly repairs, and a newer system offers lower energy costs.

If the HVAC system is in poor or broken condition, it can reduce the home's value by $5,000 to $10,000 or more. Having an experienced pro upgrade your HVAC system can prevent your home's value from decreasing and help it sell much faster.

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.
