The Problem: AC Not Cooling the House
A homeowner in Orlando called because their Goodman air conditioner was not cooling the house properly. The system ran, but indoor temperatures stayed too high on hot afternoons.
Diagnosis: More Than One Problem
Our technician's diagnostics revealed two issues:
- The evaporator coil was old and failing. A leaking or damaged coil loses refrigerant and cannot absorb heat from the indoor air efficiently.
- The line set had no filter drier. A filter drier traps moisture and debris in the refrigerant circuit. Without one, contaminants circulate through the system and can damage the metering device and compressor.
The Repair
The technician replaced the evaporator coil and installed a filter drier in the line set, then evacuated the system and charged it correctly. With a sound coil and a protected refrigerant circuit, the AC cooled the house normally again.
Why the Filter Drier Matters
Whenever a sealed system is opened, moisture and debris can enter. Moisture combines with refrigerant oil to form acids that attack compressor windings. A new filter drier is inexpensive protection and should be installed whenever a coil, compressor or other sealed-system part is replaced.
Signs Your Evaporator Coil Is Failing
- The system runs longer but the house does not cool.
- Ice forming on the coil or refrigerant lines.
- Rising electric bills.
- A hissing sound near the indoor unit.
