Hey There! Mark Here!
Your Goodman 5-Ton 14 SEER2 R-32 System—featuring the GLXS4BA6010 air conditioner condenser and the AMST60DU1300 air handler—is built to deliver powerful, energy-efficient cooling for large spaces. But like any HVAC system, even top-quality equipment can sometimes experience hiccups. The good news? Many common cooling issues can be identified and addressed without a major repair bill.
In this guide, I’ll walk you through the most common cooling problems homeowners face with a 5-ton system and give you practical steps to troubleshoot each one.
1. AC Blowing Warm Air
When your Goodman 5-Ton system starts pushing out warm air instead of cool, it’s often linked to restricted airflow or refrigerant issues.
Common causes:
-
Dirty or clogged air filters
-
Refrigerant leaks
-
Blocked or dirty condenser coils
-
Incorrect thermostat settings
How to fix it:
-
Replace or clean your air filter every 30–90 days. Dirty filters restrict airflow and make your AC work harder. According to the U.S. Department of Energy, this one simple step can lower your energy use by 5–15%.
-
Check the thermostat to ensure it’s set to “cool” and the fan is on “auto.”
-
If airflow is still weak, check your outdoor condenser coil for dirt and debris. A light cleaning with a garden hose can help, but avoid bending the fins.
-
Refrigerant leaks should always be handled by a licensed technician. R-32 refrigerant requires safe handling practices.
2. System Running Constantly
A system that won’t shut off can lead to higher utility bills and unnecessary wear on your AC.
Common causes:
-
Undersized system (not likely with a 5-ton unit unless your home is very large)
-
Dirty evaporator or condenser coils
-
Leaky ductwork
-
Incorrect thermostat placement
How to fix it:
-
Inspect your ductwork for leaks. Sealing and insulating ducts can improve efficiency by up to 20%, according to the EPA’s ENERGY STAR program.
-
Move heat-producing appliances (like lamps) away from your thermostat, which can cause inaccurate temperature readings.
-
Schedule annual professional maintenance to keep coils clean and refrigerant levels correct.
3. Weak Airflow from Vents
Poor airflow means your system may struggle to distribute cool air evenly throughout your home.
Common causes:
-
Dirty air filters
-
Blocked vents or registers
-
Duct obstructions
-
Blower motor issues
How to fix it:
-
Ensure that all vents are open and unobstructed.
-
Change your air filter if it looks dirty.
-
If the blower motor is failing, you’ll need a professional inspection. For more details on blower function, HVAC.com provides a clear breakdown of common signs of blower failure.
4. Unusual Noises During Operation
If your Goodman 5-Ton unit starts making grinding, squealing, or rattling noises, don’t ignore it.
Common causes:
-
Loose parts
-
Motor bearings in need of lubrication
-
Debris in the outdoor condenser fan
-
Failing compressor
How to fix it:
-
Turn off power to the unit and remove any visible debris.
-
Tighten loose screws or panels.
-
If you hear grinding or squealing, this likely indicates motor or compressor problems—call a professional immediately. The Air Conditioning Contractors of America (ACCA) recommends professional servicing at least once a year to prevent costly breakdowns.
5. System Short Cycling (Turning On and Off Quickly)
Short cycling not only reduces cooling performance but also places extra stress on your AC.
Common causes:
-
Oversized system (not likely with a 5-ton properly matched to your home)
-
Thermostat issues
-
Refrigerant problems
-
Dirty coils
How to fix it:
-
Start with the thermostat—replace the batteries or recalibrate it if necessary.
-
Check and clean coils to improve efficiency.
-
If refrigerant levels are low, contact an HVAC technician. For an in-depth guide on refrigerant management, see the EPA’s refrigerant handling guidelines.
Final Thoughts
Troubleshooting your Goodman 5-Ton 14 SEER2 R-32 system can help you resolve many common cooling issues before they escalate into major repairs. Simple steps like replacing filters, cleaning coils, and checking thermostat settings go a long way in maintaining efficiency.
But if problems persist—especially those involving refrigerant or electrical components—it’s always safest to call a licensed professional. For homeowners considering a new installation or needing system details, check out the Goodman 5-Ton 14 SEER2 R-32 System (GLXS4BA6010 + AMST60DU1300).
