Three-Thermostat AC System Stopped Cooling in Apex
What the customer reported
An Apex homeowner reported that their system was not cooling, shortly after a previous service visit.
What we found and did
Nick and Jeorell called for cool at all 3 thermostats and found the indoor unit running, but the outdoor board was flashing a 4 LED fault code, which was a lockout. They cycled power and checked pressures, which were low. With the homeowner's permission, they performed a leak search and discovered leaks at the evaporator coil and TXV. A repair estimate was prepared, along with an estimate for an SS2 to help prevent water from gathering in the drain pan.
Result
After the power cycle the system started to cool, and a repair estimate for the leaks was set to follow once all information was gathered.
Why quality evaporator coil services matters in Apex
Summer Heat Stress
Apex's hot, humid summers with temperatures regularly exceeding 90°F put extra strain on AC systems, requiring more frequent maintenance to handle constant use and moisture.
Seasonal Demands
The Triangle's seasonal temperature swings mean HVAC systems must efficiently handle both heating in winter and cooling in summer, with proper tune-ups before each season.
Humidity Management
High humidity levels in Apex cause condensation issues and can lead to mold growth in ductwork if systems aren't properly maintained and sized.
Local Compliance
Local building codes and HOA requirements in Apex neighborhoods require specific permits for HVAC installations and replacements to ensure compliance.

Evaporator Coil Services in Apex: questions answered
Answered by our licensed technicians serving Apex.
How do I know if my evaporator coil needs service?
Common signs include reduced cooling, ice forming on the indoor unit, higher energy bills, or the system short-cycling. A temperature split test (measuring air temperature at supply and return vents) can quickly confirm coil issues.
Can a dirty evaporator coil be cleaned or does it need replacing?
In most cases, professional chemical cleaning restores performance. Replacement is recommended when coils have refrigerant leaks, severe corrosion, or when cleaning costs approach replacement value on older systems.
How long does an evaporator coil replacement take?
Most residential coil replacements are completed in 2 to 4 hours, including recovery of existing refrigerant, coil swap, brazing, pressure testing, and recharging the system.
Why does my evaporator coil keep freezing?
Freezing is typically caused by low refrigerant (from a leak), restricted airflow (dirty filter or failing blower), or a malfunctioning expansion valve. We diagnose and fix the underlying cause, not just the symptom.
Does replacing the evaporator coil require replacing the whole system?
Not usually. If the coil is matched to your existing condenser and furnace, standalone replacement is fine. However, if your system uses R-22 refrigerant or is 15+ years old, a full system upgrade may be more cost-effective.
