🏠 Introduction: Tony’s Rule of Thumb
When Tony installed his new Goodman 3 Ton 13.4 SEER2 system, he wanted more than cool air—he wanted it to last. His contractor told him something that stuck:
“Your AC doesn’t die of old age. It dies of neglect.”
That advice motivated Tony to build a simple maintenance routine to keep his system efficient, reliable, and long-lasting.
This guide lays out Tony’s seasonal checklist and explains how to care for your Goodman AC so it delivers 15–20 years of dependable performance.
🧹 Monthly Maintenance (DIY Tasks)
🔄 Change or Clean Air Filters
-
Replace disposable filters every 30–60 days.
-
Wash reusable filters with mild soap and water.
-
Dirty filters restrict airflow, forcing your system to work harder.
💡 Tony sets a reminder on his phone for the first Saturday of every month to check his filter.
📱 Check Thermostat Settings
-
Ensure the thermostat is set to “Auto,” not “On,” to avoid unnecessary fan use.
-
Consider upgrading to a smart thermostat for better efficiency.
👂 Listen for Unusual Noises
-
Rattling, buzzing, or grinding may signal loose parts or motor issues.
-
Catching problems early prevents costly repairs.

🌸 Spring Maintenance (Before Cooling Season)
Spring is the most important maintenance season, since your Goodman is about to work hard.
🧹 Outdoor Unit Cleanup
-
Clear leaves, sticks, and dirt from around the condenser.
-
Maintain 2–3 feet of clearance on all sides.
-
Check that the unit sits level on its pad.
🧊 Refrigerant Line Check
-
Inspect insulation around refrigerant lines.
-
Replace any sections that look cracked or worn.
⚡ Electrical System Inspection
-
Check breaker panel and disconnect box for wear.
-
Ensure wiring is intact and secure.
🚀 Test Run Before the First Heatwave
-
Run the system for 15–20 minutes.
-
Confirm cool air flows evenly from vents.
💡 Tony does his spring checkup in April—long before the first hot day—to avoid surprises.

☀️ Summer Maintenance (Peak Season)
In July and August, the Goodman runs daily. Keeping it efficient requires attention.
🌿 Maintain Clearance Around Condenser
-
Trim grass, shrubs, and vines back.
-
Keep airflow unobstructed for proper cooling.
🚿 Coil Fin Rinse
-
Use a garden hose (gentle spray) to wash dirt and pollen off condenser fins.
-
Never use a pressure washer—it can bend fins.
💧 Monitor Indoor Humidity
-
Indoor relative humidity should stay near 50%.
-
If it creeps higher, check filters and airflow.
📊 Watch Energy Bills
-
Sudden spikes often mean airflow or refrigerant problems.
-
Catching issues early avoids compressor strain.
Tony rinses his coils every June to ensure top performance before July’s heatwaves.

🍂 Fall Maintenance (After Summer)
When cooling demand drops, fall is perfect for deep cleaning and prep.
🌀 Coil Cleaning
-
End-of-season coil cleaning removes built-up grime.
-
For heavy buildup, schedule professional cleaning.
🛠️ Ductwork Inspection
-
Check for loose joints or visible dust buildup.
-
Consider duct sealing or cleaning every 5–7 years.
⚙️ Blower Motor & Drain Line Check
-
Inspect blower motor for dust and lubrication needs.
-
Clear condensate drain line to prevent clogs and mold.
🔄 System Reset
-
Adjust thermostat for fall/winter comfort.
-
Switch fan setting to “Auto” if it was on continuous circulation.
Tony discovered a small duct leak one fall that explained why his upstairs rooms ran warmer—fixing it improved comfort and efficiency.

❄️ Winter Maintenance (Off-Season)
In the Northeast, central AC sits idle for months. Winter care prevents off-season damage.
🪶 Cover the Condenser (Properly)
-
Use a breathable cover to protect from debris.
-
Don’t wrap sides tightly—this traps moisture and causes rust.
❄️ Check After Storms
-
Brush off snow or ice buildup.
-
Keep gutters clear to avoid icicles dropping onto the unit.
🌬️ Circulate Air Occasionally
-
Run the fan-only mode to keep ducts fresh.
-
Helps prevent musty odors when AC resumes in spring.
Tony bought a Goodman-branded mesh cover that allows airflow but blocks leaves and snow—perfect for New England winters.
🔧 Annual Professional Maintenance
Even with DIY care, a pro should inspect your system once a year.
👨🔧 What Pros Do in a Tune-Up
-
Clean evaporator and condenser coils.
-
Check refrigerant charge and pressure.
-
Inspect and tighten electrical connections.
-
Lubricate moving parts.
-
Test system airflow and thermostat calibration.
💵 Typical Cost
-
$150–$250 per visit in the Northeast.
-
Some installers offer annual maintenance plans for peace of mind.
Tony signs up for his contractor’s spring service plan—it costs less than $200 but extends the life of his system and protects his Goodman warranty.
📊 Cost of Neglect vs. Cost of Care
Neglecting maintenance is expensive in the long run.
❌ If You Skip Maintenance
-
Energy bills increase by 20–30%.
-
Parts wear out early (compressor replacement = $1,500+).
-
System lifespan may drop to 8–12 years instead of 15–20.
✅ If You Maintain Regularly
-
$150–$250/year for pro maintenance.
-
Filters: ~$100/year.
-
Lifespan: 15–20 years.
-
Lower repair frequency.
Tony’s neighbor skipped maintenance and faced a $2,200 compressor replacement at year 9. Tony, meanwhile, pays $200 annually and expects 15+ years of life from his system.
