How Much Does a New Air Conditioner Cost in Arizona? (2025 Guide)
Having a reliable AC unit is a pivotal part of surviving the intense Arizona heat. These units are fairly short-lived in this incredibly hot state, which is why so many people wonder about the average cost to replace an AC unit in Arizona.
However, the costs can vary significantly based on factors like the type of AC unit, the size of your home, and even the brand of the unit. That said, it’s essential to understand exactly how much you can expect to pay so you can budget accordingly.
In this article, we’ll take a closer look at the AC replacement cost in Arizona, including the various factors to consider, and other essential aspects.
Factors Influencing AC Replacement Costs in Arizona
How much is a new AC unit in Arizona? Well, it varies significantly based on a whole range of different factors. Depending on the size of your home, the features you want, and how difficult the unit is to install, the price may vary by thousands of dollars. Let’s take a closer look.
Unit Size
Naturally, the size of the AC unit directly affects cost. These units are measured in tons, and you require approximately one ton of unit for every 1,500-2,000 square feet of home that you’re cooling.
However, this varies based on insulation efficiency and other factors. The larger the unit is, the more expensive it’s likely to be.
When you get a quote from a professional HVAC company, they will do a load calculation to determine exactly how much capacity your home needs. THis will include factors like temperature efficiency and how many doors and windows your home has.
Type of AC
The type of AC unit you acquire will also affect the cost significantly. Large central air conditioning units are the most effective but also the most expensive. Small ductless mini-splits are some of the most affordable, but they’re also not as efficient as larger units. Split-system air conditioners lie somewhere between the two, both in terms of affordability and effectiveness.
Efficiency Ratings (SEER)
AC unit efficiency is measured by a Seasonal Energy Efficiency Ratio (SEER). Over the last 20 years, air conditioning units have become vastly more effective, which means their prices have increased as well.
Today, a new AC unit may have a SEER rating of between 13 and 20, with higher numbers being more efficient. The higher the efficiency rating, the more expensive the unit. However, the more efficient units have lower running costs, which means that they’re often more cost-effective in the long-term.
Installation Complexity
Air conditioning units with simple installation requirements generally turn out to be considerably more affordable than their more complex counterparts.
If the installation technicians need to modify ductwork, change insulation installations, or the entire process is lengthy and complex, you will pay more on labor costs than you would with a simpler unit.
Additional Features and Technology
Another major factor is the presence of value-added features and additional forms of technology. Attributes like smart thermostats (which can be controlled from an app), variable speed compressors, and other modern AC features can lead to significantly higher prices.
Average Cost of a New AC Unit in Arizona
The average cost for a new AC unit in Arizona is somewhere between $3,000 and $11,000, though it varies significantly based on the factors listed above. The tables below show averages for types of units, and different efficiency levels.
Average Cost by Unit Type
| Type of AC Unit | Average Cost to Replace |
| Central Air Conditioner | $11,000 – $26,000 |
| Ductless Mini-Split AC | $2,000 – $15,000 |
| Window AC Unit | $150 – $1,000 |
| Portable AC Unit | $500 – $1,500 |
Average Cost by SEER Rating
| SEER Rating | Efficiency Level | Total Cost Installed |
| 13-14 | Standard efficiency | $2,500-$6,000 |
| 15-16 | High efficiency | $3,000-$7,500 |
| 17-18 | High efficiency | $3,500-$8,600 |
| 19-21 | Very high efficiency | $4,000-$10,000 |
Top Tip: To make your air conditioner more affordable, consider applying for rebates or getting financing from an HVAC installer or financial institution.
