Hey There! Jake Here!
Your central AC system works hard to keep your home comfortable all year long—especially during those blazing summers and unexpected heat waves. But if you're only thinking about your AC when it's hot outside, you're already behind. Proper seasonal maintenance—specifically in spring and fall—can prevent expensive repairs, reduce energy bills, and extend the life of your HVAC system.
Whether you’re a first-time homeowner or just trying to avoid an emergency call, this checklist will help you stay ahead of the curve.
🌼 Spring Maintenance: Get Ready Before the Heat Hits
Spring is the time to wake your AC up gently—not crank it on and hope for the best. Here’s what should be on your list before summer temperatures kick in:
✅ 1. Change or Clean the Air Filter
A dirty filter is your system’s worst enemy. Replace or clean it every 1–3 months, depending on usage. This simple step can improve airflow and reduce strain on your system.
✅ 2. Clear Debris Around the Outdoor Unit
Leaves, twigs, and even animal nests can accumulate around your condenser. Make sure there's at least 2 feet of clearance on all sides.

✅ 3. Inspect the Insulation on Refrigerant Lines
Over time, insulation can degrade or come loose. Damaged insulation leads to energy waste and cooling inefficiency.
✅ 4. Clean the Evaporator and Condenser Coils
Dust and grime on your coils force your system to work harder. You can carefully clean them with a soft brush, vacuum, or coil cleaner.

✅ 5. Test the Thermostat
Switch to cooling mode and set the temperature a few degrees below the room temp. The AC should kick on and blow cold air within a few minutes.
🍂 Fall Maintenance: Prep for Downtime (or Heating)
Your central AC needs a little TLC in the fall too, even if you’re switching to heating. It ensures your system is clean, dry, and in good shape for next year.
✅ 1. Replace the Filter Again
Don’t skip this! If you've been running your AC all summer, the filter is likely clogged with dust and pollen.
✅ 2. Clean and Cover the Outdoor Unit
After one last cleaning, consider a breathable cover to keep out leaves, moisture, and snow. But don’t wrap it too tightly—that can trap condensation and cause rust.
✅ 3. Inspect the Ductwork
Look for obvious signs of wear, rust, or gaps. Duct leaks can account for 20–30% of energy loss, which means wasted money and uneven cooling.

✅ 4. Schedule a Professional Inspection
This is the best time to get ahead of bigger problems. An HVAC tech can test refrigerant levels, inspect electrical connections, and clean components you can’t reach.
🛠 Bonus Tips: What Not to Forget
-
Keep your drain line clear – Algae or sludge buildup can clog it and cause leaks.
-
Lubricate moving parts – If you have an older unit, lubrication helps reduce friction.
-
Check for weird noises – Clicking, humming, or grinding could mean a part is wearing out.
💡 When to Call a Pro vs. DIY
You can handle basic tasks like filter changes, cleaning, and clearing debris. But if your system:
-
Doesn’t cool properly after cleaning
-
Trips the breaker when turned on
-
Leaks refrigerant or shows ice buildup
…it’s time to bring in a licensed technician.
Final Word
Seasonal AC maintenance isn't just a box to check—it’s the difference between sweating a costly repair and enjoying reliable, efficient cooling year-round. By tackling basic upkeep every spring and fall, you extend your system’s life, lower energy bills, and reduce the risk of surprise breakdowns right when you need your AC most.
Of course, even a perfectly maintained system will eventually need an upgrade. If your current unit is aging, inefficient, or underperforming, it might be time to explore newer options.
