As temperatures soar and heatwaves linger, your home’s HVAC system becomes your best line of defense against the swelter. But without proper prep, that same system can get overwhelmed, leading to uncomfortable days, restless nights, and potential breakdowns.

Here’s how to give your HVAC the support it needs through the hottest stretch of summer, and how a home warranty from APHW can help you stay cool even when the pressure is on.

1. Watch for Heatwave Fatigue

When the mercury climbs and stays there for days, your system doesn’t get much of a breather. Long stretches of extreme heat force it to run longer and harder, and that kind of stress can lead to wear and tear on vital components.

Even newer units can struggle during a heatwave. If your system starts showing signs of fatigue—such as longer cycles or reduced airflow—it may need attention. The good news? An APHW home warranty can help cover repairs caused by normal wear and tear.

2. Change Your Filters—Yes, Again

Air filters are your system’s first line of defense against dirt and dust. But when they’re clogged, airflow suffers—and your unit must work twice as hard to push out cool air.

Most manufacturers recommend swapping filters every 1–3 months, especially during peak use. A clean filter not only protects your system, but it also helps it run more efficiently—keeping energy bills down and comfort levels up.

3. Clear the Space Around Your Outdoor Unit

Your condenser needs room to breathe. If it’s surrounded by tall grass, weeds, or debris, it can’t release heat effectively. That puts even more strain on your system, which is already working hard during a heatwave.

Take a few minutes to clear at least two feet of space around the unit and gently rinse away any dirt or buildup on the fins.

4. Use a Smart Thermostat—Strategically

A smart thermostat can be your HVAC’s best friend in the summer. These devices help regulate temperature changes more efficiently—cooling your home only when needed and reducing unnecessary runtime during the hottest hours of the day.

Avoid drastic shifts in settings (like dropping from 78°F to 68°F all at once). Small, steady adjustments are easier on your system—and more energy-efficient.

5. Schedule a Professional Checkup

A seasonal tune-up is one of the best ways to ensure your HVAC is ready for the heat. A licensed technician can check refrigerant levels, inspect components, and flag any issues before they become bigger problems.

Think of it like an oil change for your car—it’s routine maintenance that can extend your system’s lifespan and improve performance.

Bonus Tip: Keep Interior Doors Open

It may sound minor but keeping doors open between rooms helps improve airflow throughout your home. It also prevents the system from working too hard in closed-off spaces.
