Why AC Efficiency Matters in Arizona
Your air conditioner accounts for a large portion of your home’s energy usage, especially during the summer months when temperatures regularly exceed 100 degrees Fahrenheit. If you have an inefficient or outdated system, your monthly energy costs might be higher than expected.
In general, AC systems that are 10 years or older use more energy to produce the same cooling effect as newer systems. By contrast, high-efficiency AC systems require less power to maintain indoor comfort. This translates into less overall energy consumption and lower energy bills.
By upgrading to a newer unit with a higher Seasonal Energy Efficiency Ratio rating, you can reduce your energy bill by hundreds of dollars. Because these models offer better efficiency and place less stress on the power grid, utility companies often offer incentives for upgrading to energy-efficient models. This can significantly reduce upfront costs.
How to Calculate AC Energy Savings
How much money you could save by installing a new AC system depends on several factors. These include your home’s cooling needs, your current AC system’s energy consumption, and the new system’s efficiency rating.
To estimate your potential savings, divide your current AC system’s SEER2 by the new system’s SEER2. Then, multiply this number by your current energy costs. This formula can help you estimate your new energy cost.
For example, say your current AC system has a SEER2 rating of 10, and you upgrade to a system with a SEER2 rating of 16. In this case, your AC system’s energy consumption would drop by 30-40%.
In Arizona, homeowners spend an average of $1,500 or more yearly on cooling costs. Therefore, a 40% efficiency gain could save around $600 annually. Contact an HVAC professional for an energy audit to get a more accurate estimate based on your home’s usage.
SEER2 Ratings: Efficiency vs. Cost Savings
SEER2 ratings determine how efficiently an AC system converts electricity into cooling power.
- Lower SEER2 (10-14): This rating is typical of older, less efficient models and contributes to higher energy costs.
- Mid-range SEER2 (16-18): This rating indicates greater efficiency, balancing upfront costs with long-term savings.
- High SEER2 (20+): This indicates premium efficiency with the most energy savings but a higher upfront investment.

Although AC systems with higher SEER2 cost more initially, they provide substantial savings over time. Many homeowners find these units pay for themselves in 5-7 years.
Other Factors That Impact Your AC’s Energy Savings
Aside from SEER2 ratings, several other elements influence how much you’ll save with a new AC system. These include:
- Home insulation and air leaks. If your home has inadequate insulation, your AC system has to work harder.
- Ductwork condition. Leaky ducts can waste up to 30% of cooled air, increasing costs.
- Thermostat settings and smart controls. Programmable thermostats optimize energy use.
- Regular maintenance. A well-maintained AC system runs more efficiently and lasts longer.
When to Upgrade Your AC for Maximum Savings
If your AC system is over 10 years old, struggles to cool efficiently, or causes frequent high energy bills, it may be time to upgrade. These signs can indicate it’s time for a replacement:
- Frequent breakdowns and costly repairs
- Increasing energy bills despite maintenance
- Uneven cooling or hot spots in your home
- Your current AC system uses R-22 refrigerant, which is being phased out
Investing in a new energy-efficient AC system helps Arizona homeowners maintain their homes’ comfort while reducing long-term costs.
