8 Pro Tips to Keep Your AC Running Cool for Years to Come

In the heart of summer, your air conditioner is the unsung hero of your home. It works tirelessly to keep you cool and comfortable, often for decades. But like any hardworking appliance, its longevity depends on how well you care for it. Here are the top 8 strategies to help your AC unit beat the heat for many summers to come.

1. Don’t Skip Annual Professional Maintenance

This is rule number one, no exceptions. Each spring, have an HVAC professional perform a comprehensive tune-up. They’ll clean coils, check refrigerant levels, inspect electrical connections, and more. It’s like a yearly physical for your AC, catching small issues before they become system-threatening problems. Many AC failures can be traced back to skipped maintenance.

2. Change or Clean Filters Monthly

Your AC’s air filter is its first line of defense against dust, pollen, and pet hair. When this filter gets clogged, your system has to work much harder to pull air through, straining the compressor. During peak cooling season, check your filter monthly. If it’s dirty, replace it (for disposable filters) or clean it (for reusable types). This simple task can extend your AC’s life by years.

3. Keep the Outdoor Unit Clear

Your AC’s outdoor compressor unit needs to breathe. Ensure there’s at least two feet of clear space around it and five feet above. Trim back shrubs, clean off grass clippings, and remove any debris. Good airflow is critical for efficient operation. Also, check that the unit is level; if not, it can cause compressor wear.

4. Clean the Condenser Coils

The outdoor unit’s condenser coils release heat from your home. Over time, they accumulate dirt and grime, making heat transfer less efficient. Once a year (more if you live in a dusty area), gently clean these coils with a soft brush and a commercial coil cleaner. Always turn off power to the unit first. This task boosts efficiency and prevents unnecessary strain.

5. Don’t Overwork Your AC

On scorching days, it’s tempting to set your thermostat super low. But asking your AC to cool your home 20 degrees below the outdoor temperature is like asking a sprinter to run a marathon at top speed. Instead, aim for a reasonable indoor temperature, around 78°F when you’re home. Each degree higher can save 3% on cooling costs and reduce system wear.

6. Use Ceiling Fans Wisely

Ceiling fans don’t lower the temperature, but they make you feel cooler by creating a wind-chill effect. Running a fan lets you set the thermostat about 4°F higher without sacrificing comfort. This takes a load off your AC. Remember, fans cool people, not rooms, so turn them off when you leave.

7. Seal and Insulate

Your AC works hard to generate cool air; don’t let that effort go to waste. Ensure your home is well-insulated, especially in the attic where heat accumulates. Seal any air leaks around windows, doors, and electrical outlets. The less cool air escapes, the less your AC has to produce, extending its life.

8. Listen and Respond to Your AC

Your air conditioner communicates through sounds and performance. Unusual noises—grinding, scraping, or loud bangs—are distress signals. Don’t ignore them. Similarly, if your AC isn’t cooling as effectively or runs constantly, something’s wrong. Prompt attention to these signs can prevent a minor issue from escalating into a system breakdown.

By following these eight strategies, you’re not just maintaining an appliance; you’re protecting an investment. A well-maintained air conditioner can last 15 to 20 years, compared to just 8 to 10 years for a neglected one. That’s potentially a decade more of cool, comfortable summers. Plus, an efficiently running AC uses up to 30% less energy, keeping both your home and your finances cool. Give your hardworking AC the care it deserves, and it will return the favor with years of reliable service.
