Why Seasonal Air Conditioner Maintenance Matters
Skipping regular service may not seem like a big deal at first, but the long-term impact on your energy bills, indoor comfort, and system reliability can be significant. St. Louis summers are especially tough on air conditioners due to the humidity and frequent temperature swings. A well-maintained AC system will:
- Run more efficiently, reducing energy costs
- Prevent unexpected breakdowns in extreme heat
- Improve airflow and indoor air quality
- Extend the life of the unit
- Help keep your warranty intact

Seasonal AC Maintenance for Spring and Summer
Schedule a Professional Tune-Up Before the Heat Hits
Spring is the best time for a full air conditioner maintenance checkup. Getting your system inspected and cleaned before you turn it on for the season ensures everything is working at peak performance when you need it most.
At Galmiche & Sons, our spring air conditioner maintenance service includes:
- Checking refrigerant levels and pressures
- Cleaning condenser coils
- Inspecting and tightening electrical components
- Lubricating motors and moving parts
- Cleaning or replacing air filters
- Testing system startup and airflow
- Verifying thermostat operation
Monitor Your System Throughout the Summer
Even with a spring tune-up, keep an eye out for signs that your AC might need attention during peak summer use. These include:
- Warm air blowing from vents
- Weak airflow or hot spots
- Strange noises or smells
- Higher-than-normal energy bills
If you notice any of these issues, schedule a service visit right away to prevent further damage.
Fall and Winter AC Maintenance Tips
While your air conditioner isn’t in use during the colder months, there are still steps you can take to preserve its condition.
End-of-Season Cleaning and Inspection
After your AC has worked hard all summer, schedule a post-season inspection. Your fall AC maintenance should help identify any wear or damage before it sits idle all winter.
- Remove debris from around the outdoor unit
- Clean the unit and coils
- Cover or protect the AC to guard against ice and snow buildup
Check Your Thermostat and Airflow Settings
As you switch to heating, make sure your thermostat is functioning properly and your vents are open and clean. This will help maintain indoor comfort and reduce stress on your HVAC system year-round.
