How Often Should I Service My AC?
When Missouri summers hit, your AC doesn’t just cool your home, it keeps your family comfortable and your air quality healthy. But even the best systems need regular care to perform efficiently. So, how often should you schedule professional AC maintenance?
Most Missouri homeowners benefit from two service visits per year, once in spring and once in fall. Here’s why.
1. Spring Tune-Up: Prepare for Peak Cooling Season
Your air conditioner works hardest from May through September in Chesterfield, when humidity and temperatures rise. A spring tune-up ensures your system is ready before it’s under stress.
During a spring visit, technicians typically:
Clean and inspect coils and condenser units
Test refrigerant levels and pressure
Check blower motors and capacitors
Clear the condensate drain line
Verify thermostat accuracy
🧠 Pro Tip: Preventive maintenance can extend your system’s life by up to 30%, saving you thousands in early replacements.
2. Fall Tune-Up: Protect Your System and Save Energy
A fall maintenance visit prepares your AC and overall HVAC system for a long rest and gets your heating system ready for cold weather. Even if you don’t run your AC in winter, fall maintenance keeps dust and moisture from creating efficiency problems.
During fall service, a technician may:
Inspect belts and bearings
Test airflow and duct pressure
Lubricate moving parts
Ensure your system transitions smoothly to heat mode (if applicable)
3. Why Twice a Year Is Ideal in Missouri’s Climate
Missouri experiences extreme humidity and temperature swings, which strain HVAC components more than in milder regions. Dirt buildup, condensation, and electrical wear are more frequent here than in drier states.
Scheduling both a spring and fall visit helps you:
Maintain energy efficiency year-round
Avoid unexpected mid-season breakdowns
Keep manufacturer warranties valid
Improve indoor air quality
4. Signs You Might Need Service Sooner
Even with regular maintenance, it’s smart to call a pro if you notice:
Weak airflow or inconsistent cooling
Strange noises from the outdoor unit
Higher-than-normal energy bills
Musty or burning odors
Ice forming on the refrigerant lines
Ignoring these warning signs can turn a small issue into an expensive repair.
Routine maintenance isn’t just about preventing breakdowns; it’s about protecting your investment. Two quick visits per year keep your system efficient, your home comfortable, and your energy bills low. With Fresh Air Heating & Cooling, you’ll always have a trusted local team ready to help.
