AC Not Cooling and Freezing Up in a Durham 27707 Home

What the customer reported

A Durham homeowner reported the system was not cooling, and the unit was freezing up.

What we found and did

Dexter found the evaporator coil clogged. He checked the system and the pressures were low, then checked the unit for leaks. He cleaned the coil and topped off the refrigerant. He also noted that a clogged coil could damage the TXV, and if the problem persists, the TXV should be changed.

Result

The system was working good after the coil was cleaned and the refrigerant topped off.

Apartment AC Back to Cooling on a Late-August Day in Durham

Durham · August 2026 · Jeorell · From our service records

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.

Late-Summer Cooling System Restored in Durham

Durham · August 2026 · Travis & Jeorell · From our service records

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.

Retrofitting Challenges

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.

FAQ

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 take several hours, including recovering the existing refrigerant, swapping and brazing in the new coil, pressure testing, pulling a vacuum, 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.
