🏡 Introduction: Protecting Your Investment
When Tony installed his Goodman 3.5 Ton 13.5 SEER2 system, he knew the purchase was just the beginning. Like any major home system, an air conditioner’s performance depends on how well it’s maintained.
Without routine care, even the most efficient AC will:
-
Consume more energy.
-
Struggle with humidity control.
-
Suffer premature breakdowns.
-
Lose warranty protection.
This guide walks through a comprehensive seasonal maintenance plan for Goodman’s 3.5 Ton 13.5 SEER2 system — blending Tony’s hands-on homeowner experience with best practices from HVAC professionals.
🧾 Why Maintenance Matters for Goodman Systems
1. Efficiency and SEER2 Ratings
A clean, well-maintained system operates closer to its rated 13.5 SEER2 efficiency. Dirt, dust, and neglect can reduce efficiency by 5–15%.
2. Longer System Lifespan
Routine service can extend the life of an AC system by 5–10 years, delaying costly replacements.
3. Warranty Compliance
Goodman’s 10-year parts warranty and lifetime compressor warranty require proper installation and regular upkeep. Skipping maintenance may void coverage.

🧹 Seasonal Maintenance Checklist
Tony organizes his maintenance by season, ensuring his system is always ready for Northeast weather swings.
🍂 Spring (Pre-Cooling Season Prep)
-
Replace filters: Start the season with clean airflow.
-
Clear outdoor condenser: Remove leaves, branches, and dirt. Maintain 2–3 ft clearance.
-
Inspect coil fins: Straighten bent fins with a fin comb.
-
Check thermostat: Test settings to ensure accurate control.
-
Inspect insulation: Replace worn refrigerant line insulation.
-
Professional tune-up: Tony always schedules his annual service in April, before peak demand.
☀️ Summer (Peak Cooling Season)
-
Change filters regularly: Every 30–60 days (Tony uses a 4-inch pleated filter, replaced twice per year).
-
Keep condenser clear: Trim back vegetation weekly.
-
Rinse coils: Use a garden hose (not pressure washer) to gently clean outdoor fins.
-
Check for unusual noises: Grinding, rattling, or buzzing can indicate issues.
-
Monitor energy bills: Unexpected spikes may signal refrigerant or airflow problems.
Tony’s note:
“When my bill jumps unexpectedly, it usually means my filter’s clogged or the coils need a rinse.”
🍁 Fall (Post-Cooling Season)
-
Replace filter again: Prepare for heating season if you use a shared air handler.
-
Clean condensate drain line: Flush with vinegar or warm water to prevent clogs and mold growth.
-
Inspect ductwork: Seal leaks or gaps with mastic or foil tape.
-
Cover condenser (optional): Use a breathable cover to protect from falling leaves, but never wrap tightly (traps moisture).
❄️ Winter (Off-Season Care)
-
Check outdoor unit after snowstorms: Clear snow and ice buildup.
-
Maintain airflow clearance: Don’t let snow piles block the condenser.
-
Run occasional system tests: If tied to a heat pump, ensure it cycles properly.
-
Book early spring service: Tony schedules next year’s maintenance in February/March before HVAC companies get swamped.

🛠️ Professional Maintenance Tasks
While Tony handles the easy DIY steps, he relies on a technician for the annual tune-up, which includes:
-
Checking refrigerant levels and topping off if necessary.
-
Inspecting electrical connections for corrosion or looseness.
-
Testing blower motor and fan operation.
-
Cleaning evaporator and condenser coils.
-
Lubricating moving parts.
-
Calibrating thermostat accuracy.
-
Verifying system airflow and duct pressure.
Average cost: $150–$250 per visit.
Tony’s comment:
“I spend about $200 a year on professional service, but it saves me from $1,000+ breakdowns down the line.”
🧾 Filter Replacement Guide
Filters are the first line of defense against dust, dirt, and allergens.
-
1-inch filters: Replace every 30–60 days.
-
4–5 inch media filters: Replace every 6–12 months.
-
Washable filters: Clean monthly (less common in Goodman setups).
Tony’s strategy:
“I mark my calendar for spring and fall filter swaps. Cheap insurance for better airflow.”

🚫 Mistakes That Reduce System Life
Tony has seen neighbors shorten the life of their ACs by making these mistakes:
-
❌ Skipping filter changes.
-
❌ Blocking airflow around the condenser with shrubs or furniture.
-
❌ Using high-pressure washers on coils (bends fins).
-
❌ Ignoring small issues like refrigerant leaks or unusual noises.
-
❌ DIY refrigerant charging (illegal without certification).
🏠 Maintenance and Warranty Protection
Goodman requires proof of proper installation and maintenance to honor warranty claims.
-
Parts Warranty: 10 years (with registration).
-
Lifetime Compressor Warranty: Unit replacement if the compressor fails.
-
Exclusions: Improper installation, lack of maintenance, or unlicensed repairs.
Tony keeps a maintenance log with receipts from his technician. This documentation ensures his warranty remains valid.
