Arizona summers are no joke. With temperatures soaring well above 100°F, your air conditioner isn’t just a luxury: it’s your home’s most essential appliance. But with all that nonstop work, even the best AC system can struggle to keep up if it’s not properly maintained.
As local HVAC pros, we’ve helped countless homeowners beat the desert heat, and we know what it takes to keep your system running strong all summer long. Here’s how you can keep your cool, even when the weather doesn’t.
1. Schedule a Professional AC Tune-Up Before Peak Season
If you haven’t had your AC professionally inspected this year, now’s the time. Arizona’s extreme heat puts intense strain on every part of your system, from the compressor to the coils. A seasonal tune-up can:
- Catch small issues before they become major breakdowns
- Improve your system’s efficiency
- Lower your energy bills
- Help your unit last longer
During a maintenance visit, we’ll clean the coils, check refrigerant levels, test safety controls, inspect the electrical components, and make sure your system is running at peak performance. Preventive maintenance is hands-down the smartest investment you can make for Arizona summers.
2. Change Your Air Filter Regularly
This is a simple step that makes a huge difference. A dirty or clogged filter restricts airflow, making your AC work harder to circulate air throughout your home, and that can lead to overheating or even system failure in the extreme heat.
Our recommendation: Check your air filter every 30 days during the summer and replace it as needed. If you have pets or live in a dusty area (which is common here), you may need to change it more often.
3. Use Smart Thermostat Settings
Your thermostat settings can make or break your comfort—and your energy budget. Here’s what we suggest:
- Set your thermostat to 78°F when you’re home
- Bump it up to 85°F when you’re away
- Use a programmable or smart thermostat to manage temperature changes automatically
Avoid cranking the thermostat way down when you get home. It won’t cool your house faster, but it will overwork your system.
4. Keep the Outdoor Unit Clear
Your condenser unit needs room to breathe. Dirt, debris, and overgrown plants can block airflow and reduce your system’s ability to expel heat. How to help:
- Clear at least 2 feet of space around the outdoor unit
- Rinse off dust or debris with a gentle hose spray
- Keep nearby trees or shrubs trimmed back
If you notice odd noises, weak airflow, or warm air coming from the vents, it could be a sign that your condenser needs professional attention.
5. Don’t Ignore Warning Signs
Your AC will usually let you know when something’s wrong—if you’re paying attention. Watch for:
- Strange noises like banging or buzzing
- Warm spots in your home
- Weak airflow or increased humidity
- Rising energy bills
If something feels “off,” don’t wait. Running your AC while it’s struggling can lead to a full breakdown—and in Arizona, that can become dangerous fast. We offer fast diagnostic services to identify the issue and keep your home safe and cool.
