How to Keep Your AC Running Strong in Arizona Heat

When the desert sun cranks temps past 110°F, your AC has to work overtime. At A&A Cooling & Heating, we know what it takes to keep systems running strong in extreme Arizona heat.

Here’s how to get the most from your AC all summer—without sweating the energy bill.

‍Optimize Thermostat Settings

Your thermostat settings have a big impact on efficiency.

Here’s the sweet spot:

• Set it to 78°F when you’re home
• Raise it to 82–85°F when away

Want your system to manage itself? Upgrade to a smart thermostat like Nest or Ecobee. They automatically adjust settings, help track energy use, and even work with voice assistants.

Change (and Check!) Your Air Filter

Dust storms, pets, and pollen are part of Arizona life—and your AC filter catches it all. A dirty filter chokes airflow, causes frozen coils, and can even kill your system early.

What to do: Make sure you change your air filter every 30 days during the summer.

Seal and Insulate Your Home

Keep the cool air in—and the heat out—by insulating your home in the right places. A well-insulated home takes the pressure off your AC, helping it run more efficiently and last longer.

Focus on these areas:

• Windows & Doors
• Attics
• Ducts

DIY Hack: Close blinds or install UV-blocking window film to keep your home shaded during peak sun hours.

Schedule Preventive Maintenance

Routine maintenance isn’t just a “nice-to-have”—it’s critical in extreme temps. A tune-up from A&A Cooling & Heating keeps your system running at peak performance and helps prevent mid-summer breakdowns.

Our Maintenance Checklist:

• Refrigerant check
• Electrical inspection
• Coil cleaning
• Thermostat calibration

Avoid Overworking Your AC

Even a top-notch system needs some help. Give your AC a break now-and-then without sacrificing your comfort!

Here's how to reduce the strain:

• Use ceiling fans to circulate air and bump the thermostat up a few degrees
• Avoid daytime oven use—grill outside or prep meals in the evening
• Close vents in unused rooms to push cool air where you need it most

Consider a System Upgrade

If your system is 10+ years old or you’re constantly calling for repairs, it may be time for an upgrade. New high-efficiency units can cut energy use by up to 40%.
