9 Common AC Maintenance Mistakes That Shorten Your System’s Life

Your air conditioner works hard every summer. Simple mistakes can wear it out faster, raise bills, and lead to costly repairs. Avoid these common problems to keep your system running strong.

1. Skipping Tune-Ups

Annual service keeps parts clean and catches small issues early.

Tip: Book a professional checkup every spring.

2. Forgetting Filters

Dirty filters block airflow and strain the system.

Tip: Check monthly and replace or clean every 1–3 months.

3. Ignoring Strange Sounds or Smells

Rattles, grinding, or burning smells mean trouble.

Tip: Call an HVAC pro right away.

4. Covering Vents

Furniture or curtains over vents reduce airflow and cooling.

Tip: Keep vents clear.

5. Letting Outdoor Units Get Dirty

Leaves and grass can clog the condenser and cause overheating.

Tip: Keep at least two feet of space around the unit and rinse gently.

6. Setting the Thermostat Too Low

Turning it way down doesn’t cool faster—it only overworks your AC.

Tip: Set it around 74–78°F and keep it steady.

7. Overlooking Duct Leaks

Leaky ducts waste cooled air and raise energy costs.

Tip: Have ducts inspected and sealed.

8. Neglecting Refrigerant Levels

Low refrigerant lowers cooling power and can damage the compressor.

ip: Have a pro check and refill if needed.

9. Delaying Small Repairs

A loose wire or worn belt can turn into a big repair.

Tip: Fix issues as soon as they show up.
