-
Air quality: Regular filter replacement ensures clean, breathable indoor air and minimizes allergens.
-
Warranty coverage: Goodman warranties require proof of regular maintenance by a licensed technician to remain valid.
🧭 The Four-Season Maintenance Approach
Each season brings unique challenges for your HVAC system. Instead of waiting for problems to arise, proactive checks keep your Goodman running efficiently — no matter what the weather throws at it.
Let’s break down exactly what to do every season.
🌸 SPRING MAINTENANCE — PREPARE FOR COOLING SEASON
Spring is the ideal time to tune up your system after winter hibernation. Before the cooling season begins, make sure your Goodman heat pump is clean, calibrated, and ready for heavy use.
🧹 1. Replace or Clean Air Filters
Dirty filters restrict airflow, causing your system to consume more energy. The Environmental Protection Agency (EPA) recommends checking filters every month and replacing them at least every 90 days.
For optimal performance:
-
Use MERV 8–11 filters to balance air quality and airflow.
-
Mark your calendar or set reminders for filter changes.
-
If you have pets or allergies, replace filters every 45 days.
🌀 2. Clean the Outdoor Condenser Unit
The outdoor coil is where your system releases heat during cooling. If it’s blocked by leaves, dirt, or debris, your Goodman unit will struggle to maintain temperature.
Steps:
-
Turn off power at the disconnect switch.
-
Remove large debris (twigs, leaves).
-
Spray the coil gently with a garden hose — never use high pressure.
-
Keep at least 2 feet of clearance around the unit for proper airflow.
You can also use a coil cleaning solution approved by Goodman to remove built-up grime safely.
⚙️ 3. Inspect the Thermostat and Controls
If you’re using a programmable or Wi-Fi thermostat, spring is a good time to:
-
Check batteries.
-
Update schedules for warmer months.
-
Test heating and cooling modes to confirm correct operation.
Smart thermostats, like those recommended by ENERGY STAR, can save you up to 8% on annual heating and cooling costs.
🔌 4. Inspect Wiring, Connections & Ductwork
Loose electrical connections or leaky ducts can waste significant energy.
-
Look for signs of corrosion or damaged insulation around wiring.
-
Schedule a professional duct inspection if you suspect leaks or notice uneven temperatures.
-
Seal gaps using UL 181-rated duct tape or mastic sealant for lasting results.
According to Home Energy Saver, sealing leaky ducts can improve efficiency by up to 20%.
🧯 5. Test System Start-Up
Once everything is cleaned and checked:
-
Turn the system back on.
-
Listen for unusual noises (rattling, buzzing).
-
Confirm steady airflow and cooling.
If the air feels warm or the system cycles too quickly, you may need refrigerant or thermostat calibration. In that case, contact a licensed HVAC technician certified by NATE.
☀️ SUMMER MAINTENANCE — KEEP YOUR COOL WHEN IT COUNTS
Your Goodman heat pump works hardest in summer. Preventative care now avoids mid-season failures and ensures your 15.2 SEER2 performance rating stays consistent.
💧 1. Check the Condensate Drain
During cooling, your system removes humidity from the air. That moisture drains through a condensate line — which can clog with algae or debris.
To clean:
-
Turn off power.
-
Use a wet/dry vacuum to clear the drain line.
-
Pour a cup of vinegar through it monthly to prevent buildup.
A clogged drain can trigger the float switch and shut down your system entirely — so this simple task prevents unnecessary downtime.
🧊 2. Clean Evaporator Coils
Inside the vertical air handler, the evaporator coil absorbs heat from your home. When dirty, it reduces cooling capacity and efficiency.
If you notice weak cooling, frost on the coil, or higher bills, have a pro clean it using EPA-approved coil cleaners.
🌬️ 3. Optimize Airflow
Keep vents unblocked and ensure furniture isn’t obstructing registers. Balanced airflow helps the Goodman system maintain even temperatures and reduces runtime.
Tip: Check for cold or hot spots — it might indicate duct leaks or a zoning imbalance.
🔋 4. Verify Electrical Components
Ask your technician to inspect capacitors, contactors, and the compressor for wear. Electrical degradation is a top cause of summer outages, especially in humid climates.
Professional maintenance from ACCA-certified technicians ensures your Goodman system operates safely under load.
🍂 FALL MAINTENANCE — PREPARE FOR HEATING MODE
As outdoor temperatures drop, your heat pump reverses its cycle to deliver warmth. Fall is your chance to ensure heating components are clean and operational before winter’s chill sets in.
🔁 1. Switch Thermostat to “Heat” and Test the Cycle
Run your system for a full 15–20 minutes. It should switch smoothly from cooling to heating without unusual noises or smells.
If you notice a musty odor, it could be dust on the heat exchanger or coil — normal if unused for months, but it should clear quickly.
🪛 2. Check the Reversing Valve & Defrost Cycle
Your Goodman heat pump includes an automatic defrost cycle to prevent coil icing in winter. Ensure:
-
The reversing valve activates properly.
-
Defrost mode engages briefly (you’ll hear a whoosh sound).
If the outdoor fan doesn’t stop or frost lingers, it may signal a reversing valve malfunction — best handled by a professional.
🌫️ 3. Clear Outdoor Unit of Falling Leaves
Falling leaves and sticks can collect around the condenser, restricting airflow. Keep the area clear and trim nearby shrubs.
Maintaining a 24-inch clearance zone around the unit ensures optimal performance throughout the heating season.
🧽 4. Clean or Replace Filters Again
As you transition to heating mode, swap in a fresh filter to prevent dust buildup.
This is one of the simplest, most effective ways to maintain efficiency — yet it’s often overlooked.
According to HVAC.com, replacing a dirty filter can reduce your energy use by up to 15% immediately.
🧯 5. Schedule a Professional Tune-Up
Fall is the best time for an annual HVAC inspection — before technicians are flooded with winter emergency calls.
Your tune-up should include:
-
Refrigerant level check
-
Electrical system test
-
Coil cleaning
-
Blower calibration
-
Defrost control inspection
Professional tune-ups by a Goodman-authorized service partner ensure your warranty remains valid and efficiency optimized.
❄️ WINTER MAINTENANCE — MAXIMIZE HEATING PERFORMANCE
Winter puts your Goodman system to the test, especially in northern climates. Fortunately, heat pumps are designed to handle it — if you give them the right support.
🧊 1. Keep the Outdoor Unit Clear of Snow & Ice
After every snowfall, gently remove snow buildup from the top and sides of your outdoor condenser. Blocked airflow causes inefficiency and can trip safety switches.
Avoid using sharp tools — a broom or soft brush works best.
🌡️ 2. Use Smart Thermostat Scheduling
Heat pumps operate most efficiently when allowed to maintain steady temperatures.
Avoid drastic thermostat swings; instead, use gradual adjustments or smart learning modes.
The ENERGY STAR thermostat guide recommends setting:
-
68°F when you’re home
-
62–64°F when away or sleeping
These settings balance comfort and energy savings.
🔋 3. Monitor Backup Heat Usage
Your Goodman system may use electric resistance heat as a backup during extreme cold. If it’s running too often, it can spike your electricity bill.
Check your thermostat’s energy usage report or consult your HVAC technician to ensure the heat pump is handling most of the heating load efficiently.
🪜 4. Inspect the Air Handler
The AMST36CU1300 vertical air handler houses your blower and coil. During winter, ensure:
-
The blower compartment is clean.
