Your home’s air conditioning system is essential for year-round comfort, but how often should you service your AC to ensure it runs efficiently? Most HVAC experts recommend servicing your AC at least once a year, ideally in spring before peak cooling season. If you live in warmer climates where AC is used frequently, scheduling bi-annual maintenance (spring and fall) helps maintain peak performance.
According to the Department of Energy, replacing or cleaning air filters can reduce an AC unit’s energy consumption by up to 15%, significantly lowering utility bills.
Why Regular AC Maintenance is Essential
Regular AC servicing is critical for energy efficiency, comfort, and long-term savings.
Improves Energy Efficiency
A properly maintained system uses less electricity, reducing energy bills. A dirty or clogged filter makes your unit work harder, wasting energy.
Extends Your AC’s Lifespan
Most AC systems last 10-15 years, but regular maintenance can extend their lifespan and prevent costly repairs.
Prevents Unexpected Breakdowns
Annual check-ups detect small issues before they become expensive repairs, ensuring your AC runs smoothly when you need it most.
Protects Your Warranty
Many manufacturers, including Lennox, require regular AC maintenance to keep warranties valid.
How Often Should You Service Your AC?
Even if your system appears to be running fine, routine maintenance prevents hidden issues and maximizes efficiency.
Recommended AC Maintenance Schedule
- Once a Year – If you use your AC seasonally, one professional tune-up per year in spring is recommended.
- Twice a Year (Spring and Fall) – Ideal for warmer climates where AC runs year-round.
- Every 3–6 Months – If you have pets, allergies, or live in a dusty area, change filters more often and schedule duct cleaning.
