AC Maintenance Mistakes You Might Be Making (And How to Fix Them)
When summer heat hits hard, your air conditioner becomes your best friend. But what if it’s not working as efficiently as it should? Many homeowners unknowingly make simple AC maintenance mistakes that can reduce system performance, increase energy bills, or even lead to expensive repairs. Here are the most common mistakes - and how to fix them.
1. Skipping Filter Replacements
One of the most overlooked tasks is replacing or cleaning the air filter. A clogged filter restricts airflow, forcing your AC to work harder and decreasing its lifespan.
Fix: Check filters monthly and replace them every 1–3 months, depending on usage and filter type.
2. Ignoring Annual Maintenance
Many people skip professional AC servicing, assuming the unit is fine if it’s cooling. However, skipping tune-ups can result in hidden issues going unnoticed.
Fix: Schedule annual professional maintenance to ensure your system is running at peak performance.
3. Incorrect Thermostat Settings
Setting your thermostat too low won’t cool your home faster, but it will waste energy. Also, constantly adjusting settings causes the system to work harder.
Fix: Use a programmable or smart thermostat to set consistent, energy-efficient cooling schedules.
4. Blocking Air Vents
Furniture or curtains placed over air vents can restrict airflow and reduce efficiency.
Fix: Make sure all vents are clear and open to allow for proper circulation.
5. Not Cleaning the Outdoor Unit
The outdoor condenser unit needs space and cleanliness to operate properly. Dirt, leaves, and debris can block airflow and reduce cooling power.
Fix: Keep the area around the unit clear and rinse the coils gently with a garden hose.
6. DIY Fixes Without Proper Knowledge
While basic tasks like changing filters are safe, tampering with refrigerant lines or electrical components can cause damage and safety hazards.
Fix: Leave technical issues to certified HVAC professionals.
