How Much Does a Heat Pump Cost in Phoenix? [2025 Data]

Heat pump costs in Phoenix, Arizona, range from $4,801 to $7,376, for an average of $6,088. These prices are slightly higher than national averages, but your costs significantly depend on the type and size of your heat pump (among other factors). Here’s how it works.

Heat Pump Cost Factors in Phoenix

If you’re thinking about installing or replacing a heat pump in Phoenix, here are the main factors that will affect your costs.

Type of Heat Pump

There are several types of heat pumps available in Phoenix, but air-source and ground-source heat pumps are the most common options. Of those two, air-source heat pumps (a category that includes ductless mini-splits) are more popular. 

In terms of cost, air-source heat pumps are less expensive than ground-source heat pumps (also known as geothermal heat pumps). That’s because ground-source models require an underground pipe system, which can drive up installation costs.

Heat Pump Size

Size is something else to consider when estimating the cost of heat pump installation in Phoenix. You’ll need a bigger budget if you want a large heat pump (in other words, one with more heating and cooling capacity). 

For context, heat pump sizes are provided in tons, British Thermal Units (BTUs), or both. You can see how an air-source heat pump’s size—in either tons or BTUs—affects its price in this chart:

Efficiency Rating

Manufacturers measure heat pump efficiency in two ways: Seasonal Energy Efficiency Ratio (SEER) for cooling and Heating Seasonal Performance Factor (HSPF) for heating. With either system, a higher rating means the unit is more efficient and requires less energy to cool or heat your home. 

While high-efficiency heat pumps come with lower operating costs, they’re more expensive up front. Here’s how much you can expect to pay for a heat pump, depending on its SEER rating:

Ductwork Installation or Replacement

Most heat pumps—except ductless mini-splits—need ductwork to circulate warm or cool air throughout your home. If your home doesn’t have a duct system, you’ll need to install one. On average, this costs between $3,000 and $7,500 per 300 linear feet.

Even if you already have ductwork, your HVAC contractor might recommend replacing it if it’s old, damaged, or inefficient. Ductwork replacement costs depend on the duct material, ductwork layout, and home size. However, in Phoenix, you can expect to spend between $447 and $1,587.

HVAC Pro Costs in Phoenix

There are a few other factors that impact your heat pump budget, including professional labor, permits, and Phoenix sales tax.

Licensing and Certification

In Phoenix, any mechanical work requiring a permit (which includes heat pump installation) must be completed by a licensed journeyman or apprentice. HVAC pros in Phoenix, Arizona, should also be licensed by the Arizona Registrar of Contractors (ROC).

In addition, your installer should have a Section 608 Technician Certification from the Environmental Protection Agency, which means they’re qualified to work with refrigerants.

It’s also smart to seek out a NATE-certified professional for your heat pump installation. This is an optional certification, but if your pro has one, it means they have real-world HVAC experience, up-to-date industry knowledge, and specialized skills.

Permits

As we’ve covered, you need a permit to install a new heat pump in Phoenix. Your contractor should pull the necessary permits for your project, but as the homeowner, you’re responsible for the cost.

Sales Tax

When you buy a heat pump in Phoenix, you’ll need to pay the city’s 9.1% sales tax. That might not bust your budget, but it will increase your overall expenses. For instance, if your heat pump costs $2,500, you’d pay an additional $228 for sales tax.

Does Installing a Heat Pump Increase Home Value in Phoenix?

A heat pump is an all-in-one heating and cooling system, which is great to have in Phoenix’s desert climate. Not only can a heat pump keep you cool on the Valley’s scorching summer days, but it will also help you stay warm on chilly winter nights.

If you end up selling, a new heat pump is something buyers will appreciate, too. In fact, an upgraded HVAC system can increase your home’s value by 5% to 7%.
