How to Extend the Life of Your Air Conditioner

Is your air conditioner working harder than it should? You’re not alone. Homeowners and business owners across the region want their AC to run smoothly, especially when the heat arrives. Yet, too many units wear out years early—sometimes from simple things that were overlooked. At Holmes Heating & Air, we know a few smart habits can add up to big savings and fewer breakdowns.

Let’s talk about how you can stretch every season from your AC investment, keep your indoor air fresh, and avoid those dreaded midsummer meltdowns.

How Air Conditioners Wear Out

Air conditioners aren’t all that different from your car. Give them the right care, and they’ll keep humming along. But skip a few basics, and the problems start to pile up.

Here’s what typically causes ACs to age before their time:

• Clogged filters: Like trying to breathe through a straw, your system strains to move air, burning out parts faster.
• Dirty coils: Dust and grime settle on the coils, making it harder to cool your home efficiently.
• Low refrigerant: Tiny leaks sap efficiency and force the compressor to work overtime.
• Blocked drains: Water backs up, leading to musty smells or even water damage.
• Worn electrical parts: Time and heat take their toll, causing shorts and blown fuses.

When these small issues stack up, your AC has to run longer and harder to keep you comfortable. That’s when wear accelerates—and breakdowns follow.

Maintenance Musts for a Longer-Lasting AC 🛠️

So, what’s the secret to a long-lived air conditioner? Consistent, simple care. Here are the habits that make the biggest difference:

1. Change Your Filters Regularly

A dirty air filter is the silent killer of AC units. Change it every 1–3 months—more often if you have pets, allergies, or live in a dusty area. It’s cheap insurance. Learn more about AC filters and best practices here.

2. Clean the Coils

Both the evaporator (inside) and condenser (outside) coils collect dust. Gently rinse the outdoor coil with a garden hose (never a pressure washer). For indoor coils, professional cleaning prevents buildup and keeps things running at peak efficiency.

3. Annual Tune-Ups

Just like a checkup at the doctor, your AC needs a yearly inspection. A certified technician will check refrigerant, test electrical connections, and make sure everything’s safe. This is also when small issues get caught before they turn into big repairs.

4. Use a Smart Thermostat

Smart thermostats help your system run only when needed. Set it a few degrees higher when you’re away, and let it cool just before you return. Over time, this simple habit can cut down on wear and lower your bills.

5. Keep the Area Clear

Give your outdoor unit some breathing space. Trim back shrubs or grass at least two feet away. Clear leaves and debris after storms. This helps airflow and makes maintenance easier.

6. Schedule Professional AC Maintenance

Professional care goes beyond what you can do yourself. Holmes Heating & Air’s technicians are certified, follow manufacturer guidelines, and help keep your warranty valid. We’ll inspect, clean, and test your system so it’s ready for whatever the season brings.

Signs Your AC Is Showing Its Age

No one wants to be caught off guard by a failing air conditioner. Watch for these red flags:

• Weaker airflow: If your rooms don’t feel as cool, it’s a sign something’s blocking the system or wearing out.
• Frequent cycling: Turning on and off more often than usual? That’s hard on the compressor.
• Unusual noises: Grinding, squealing, or rattling sounds spell trouble.
• Inconsistent temperatures: Hot and cold spots mean the system isn’t balancing air properly.
• Higher energy bills: Rising costs without changing your habits usually means efficiency is slipping.

If you notice any of these, it’s time for a checkup. Early action can save you from a total breakdown.

When Is It Time to Replace Your Air Conditioner?

Even with the best care, no AC lasts forever. Most units give reliable service for 10–15 years, sometimes a bit less in harsh climates or heavy use.

Consider replacement if:

• Your unit is over 15 years old and needs frequent repairs.
• The cost of fixing a major part (like the compressor) is close to half the price of a new system.
• Your energy bills have spiked, even after filter changes and tune-ups.
• Your home never feels quite comfortable, no matter what you try.

Modern HVAC systems can be up to 30% more efficient than those made just a decade ago. Upgrading can mean better comfort, lower bills, and improved indoor air quality.

Practical AC Maintenance Tips

• Set calendar reminders for filter changes and annual tune-ups.
• Check your thermostat batteries every spring.
• Inspect your outdoor unit after heavy storms or yardwork.
• Listen for odd noises and call for help if anything changes.
• Keep windows and doors closed when the AC is running to avoid overworking the system.

Frequently Asked AC Life Extension Questions

Q: How often should I schedule professional AC maintenance?
A: Once a year is ideal. Early spring is best—before the rush of summer heat.

Q: Is it safe to clean my own AC coils?
A: You can gently hose off the outside unit, but indoor coils should be cleaned by a professional to avoid damage or voiding your warranty.

Q: Does a smart thermostat really help?
A: Yes! Smart thermostats help you avoid unnecessary run time, reducing wear and saving energy.

Q: What about air quality—does that affect AC life?
A: Absolutely. Dust and debris clog filters and coils, making your system work harder. Regular IAQ testing and filter changes protect both your AC and your health.

Local and Seasonal Considerations

Living in an area with big swings in temperature or lots of pollen? Your AC faces unique challenges. Heavy use during heat waves and long idle periods in winter both stress the system. That’s why AC Maintenance help in Brookings, South Dakota is so important—seasonal checkups keep your AC ready for anything.

If your business relies on cooling to protect products or keep staff comfortable, consider a twice-yearly maintenance plan. Commercial units face different demands than home systems.
