Apartment AC Back to Cooling on a Late-August Day in Durham
What we found and did
At an apartment in the 27703 area of Durham, the property had already supplied the parts and refrigerant for a labor-only coil and freon replacement. Jeorell removed the old coil and installed the new coil, then put the system under a pressure test and tested for leaks. He pulled vacuum to manufacturer specs and added the factory charge of 410a using refrigerant supplied by the apartment, adding 2 lbs of his own 410a when the supplied tank ran empty.
Result
Jeorell took a temperature split, and the system was cooling at the time of departure.

August 2026
Late-Summer Cooling System Restored in Durham
What we found and did
Travis and Jeorell removed the existing indoor coil at a Durham home in the 27703 area and replaced it with a new indoor evaporator coil. After installation, they secured all refrigerant connections and pressure tested the system with nitrogen to verify the integrity of the refrigerant circuit, then released the nitrogen and pulled a deep vacuum to remove air and moisture. Once the vacuum was confirmed stable and met the required evacuation specifications, they weighed in the refrigerant charge according to the manufacturer's specified charge requirements.
Result
The system held the required nitrogen pressure with no leaks detected and was back up and running, operating as expected following the indoor coil replacement.
Why quality evaporator coil services matters in Durham
Historic to Modern
Durham's diverse housing stock ranges from historic homes to modern builds, each requiring different HVAC approaches and solutions.
Bull City Summer Heat
The Bull City's hot, humid summers with temperatures often exceeding 90°F demand reliable AC systems with proper maintenance schedules.

Many older Durham homes have ductwork that wasn't designed for central AC, requiring creative solutions and expert retrofitting.
Outdoor Unit Care
Durham's tree-lined neighborhoods provide shade but also shed debris that can clog outdoor AC units, requiring regular cleaning and maintenance.

Evaporator Coil Services in Durham: questions answered
Answered by our licensed technicians serving Durham.
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.
