Why Spring AC Maintenance Matters
Your air conditioner works hardest during the summer months. If it’s not properly inspected and tuned up beforehand, small issues can lead to bigger, more expensive problems. A spring tune-up helps ensure:
- Reliable operation during extreme heat
- Lower monthly energy bills
- Fewer breakdowns and emergency repairs
- Longer lifespan for your AC system
With more than 70 years of experience in the HVAC industry, Galmiche & Sons has seen firsthand how preventive maintenance can save homeowners time, money, and stress.
DIY Spring Air Conditioner Maintenance Tips
While it’s important to have a professional HVAC technician inspect and service your system each spring, there are a few things homeowners can do themselves to prepare their AC for summer.
1. Replace the Air Filter
A dirty or clogged air filter restricts airflow and forces your system to work harder. Check your HVAC air filter monthly and replace it at least every 60 to 90 days, or more often if you have pets or allergies.
2. Clear Debris Around the Outdoor Unit
Over the winter, leaves, sticks, and dirt can collect around your outdoor condenser unit. Clear away debris and trim plants or shrubs at least two feet back to ensure proper airflow.

3. Inspect Vents and Registers
Check that all vents inside your home are open and unobstructed by furniture, rugs, or curtains. This helps distribute air evenly throughout your space.
4. Check the Thermostat
Test your thermostat by turning on your cooling system and making sure it responds correctly. Consider upgrading to a programmable or smart thermostat to improve energy efficiency.
5. Look and Listen for Unusual Signs
Turn on your AC and observe how it sounds and feels. Listen for unusual noises, watch for weak airflow, and check if any rooms feel warmer than others. These signs may indicate it’s time for a professional inspection.

The earlier the better. March through early May is ideal, before the busy season begins and temperatures spike.
Skipping maintenance increases the risk of breakdowns, higher energy bills, and even premature system failure. A simple tune-up can help you avoid these headaches.
