Phoenix summers are relentless, with daytime temperatures often soaring into the triple digits for weeks at a time. For homeowners, this extreme heat means relying heavily on air conditioning, which can quickly drive up electricity bills and put serious stress on your HVAC system. At Arcadia Air, we believe staying cool shouldn’t come at the cost of comfort, energy efficiency, or long-term wear on your system.
That’s why we’ve compiled this list of smart, energy-conscious strategies to help you keep your home cooler, even on the hottest days, without overworking your AC.

1. Block Out the Sun During Peak Heat Hours
Solar heat gain, or the increase in temperature due to sunlight entering your home, is a major contributor to rising indoor temperatures, especially in desert climates like Phoenix. West and south-facing windows are particularly vulnerable.
Here’s how to minimize indoor heat from sunlight:
- Close curtains or blinds from mid-morning through late afternoon (typically 10 a.m. to 4 p.m.).
- Install heat-reflective window film or solar screens, which block UV rays and reduce thermal transfer.
- Hang blackout shades or thermal drapes in rooms that receive direct sunlight.
- Use awnings or exterior shutters to shade large windows and patio doors.
Reducing sunlight penetration can prevent your indoor temperature from climbing dramatically throughout the day, making it easier for your AC to keep up.
2. Switch to Energy-Efficient LED Lighting
You may not think about your lighting as a heat source, but traditional incandescent and halogen bulbs convert most of their energy into heat. This added warmth contributes to your home's overall temperature, particularly in smaller or enclosed spaces.
Why LEDs (Light Emitting Diodes) are a smart switch:
- LEDs produce minimal heat, unlike traditional bulbs.
- They consume less energy, reducing your electricity bill.
- They last longer, meaning fewer replacements and less waste.
Upgrading your lighting is a quick, cost-effective way to lower indoor temperatures and reduce your overall energy consumption, especially in frequently used rooms like kitchens and bathrooms.
3. Use Fans Strategically for Better Air Circulation
Fans don’t lower the temperature of a room, but they improve airflow and make you feel cooler through evaporative cooling on your skin. With a fan, you can raise the thermostat a few degrees and still stay comfortable.
Tips for optimal fan use:
- Set ceiling fans to spin counterclockwise in summer to push cool air down.
- Place oscillating or box fans near windows in the early morning or evening to pull in cooler outside air.
- Use exhaust fans in kitchens and bathrooms to remove heat and humidity.
Strategic use of fans allows your AC to work less hard while maintaining a pleasant environment, especially when combined with window shading and smart insulation.
4. Seal Air Leaks and Improve Insulation
Unsealed cracks and poor insulation can allow cool air to escape and hot air to enter, making your AC work harder than necessary. Addressing these areas helps retain cooled air longer and improves temperature control and efficiency.
Focus your efforts on these areas:
- Inspect windows and doors for visible gaps; seal them with weatherstripping or caulk.
- Check around baseboards, outlets, and attic hatches for leaks and add insulation as needed.
- Add or upgrade insulation in attics, basements, and crawl spaces to create a more thermal-resistant barrier.
- Seal ductwork to prevent air loss in your HVAC system.
Improving insulation and sealing air leaks creates a tighter, more efficient home envelope. This helps your AC operate more effectively with less effort.
5. Cook Smarter During the Day
Cooking indoors, especially with an oven or stovetop, can quickly raise your kitchen temperature and spread heat throughout your home. During a Phoenix summer, that extra heat can overwhelm your AC’s ability to maintain a comfortable environment.
Try these alternatives to minimize cooking heat:
- Use small appliances like a microwave, toaster oven, or slow cooker.
- Grill outside during cooler hours to keep the heat outdoors.
- Prepare no-cook meals like salads, wraps, or sandwiches on the hottest days.
Adjusting your cooking habits during peak hours can help prevent unnecessary indoor heat gain and keep your kitchen more comfortable.
6. Program Your Thermostat for Energy-Efficient Scheduling
Using a programmable or smart thermostat optimizes your cooling schedule and avoids cooling empty spaces. It’s one of the simplest yet most effective ways to reduce energy usage and prevent overworking your HVAC system.
Best practices for thermostat settings:
- Set the temperature to 78°F when you’re home.
- Increase the temperature by 5–8°F when you’re away for more than a few hours.
- Use scheduling features to adjust settings throughout the day automatically.
- Consider upgrading to a smart thermostat that learns your habits and adjusts accordingly.
Automated temperature management gives your AC well-timed breaks while keeping your home cool when you need it most.
7. Keep Your AC Maintained Year-Round
No amount of hacks or tips can compensate for a poorly maintained AC unit. Dust, dirt, and wear-and-tear reduce efficiency and increase the risk of breakdowns, especially under the pressure of extreme heat.
What regular maintenance includes:
- Changing or cleaning air filters every 1–2 months during peak usage.
- Inspecting coils, drain lines, and refrigerant levels for proper operation.
- Checking for leaks or blockages in the ductwork.
- Scheduling professional tune-ups at least once a year—ideally in spring.
A well-maintained AC system performs more efficiently, lasts longer, and delivers better indoor comfort with less effort.
