The Hidden Question Every Arizona Buyer Should Ask: What’s Keeping This Home Cool?

It’s easy to fall for sparkling countertops and sleek fixtures, but for long-term comfort and cost control, your focus should be on the heart of any Arizona home: the HVAC system. Many homes built or remodeled before 2010 may still have systems that use R-22 (Freon), a refrigerant now banned in the U.S. due to its impact on the ozone layer.

Since 2020, R-22 is no longer produced or imported—making any repairs both costly and complex, as leftover supplies dwindle.Modern HVAC systems are built for the future. They use advanced refrigerants like R-410A or R-454B, which are cleaner, more energy-efficient, and fully compliant with environmental standards. These updated units are not just a win for the planet—they’re quieter, more cost-effective to operate, and align with current energy codes.

What To Ask Before You Buy: Critical HVAC Questions For Arizona Homebuyers

Don’t let an outdated HVAC become your biggest—and priciest—surprise after closing. A savvy buyer always inspects before investing. When touring homes, make sure you (or your agent, or inspector) get clear answers to these essential questions:

What year was the HVAC system installed?
What type of refrigerant does it use? (Look for R-410A or R-454B; avoid R-22 systems.)
Is the system compatible with today’s energy codes and smart thermostats?
What is the estimated cost of replacement if the unit is near or past its life expectancy?

If the system is older, get quotes on replacement before making an offer—you’ll gain negotiation power and avoid future headaches.

Real estate professionals encourage buyers to factor replacement costs into offers and highlight energy savings and lower maintenance with modern systems.

Remember: acting smart, not emotional, can save you thousands and keep your new home cool, quiet, and efficient for years to come.
