A residential complex in the 27701 area of Durham requested a leak test, and a unit was later reported as AC not working.
The first visit was rescheduled because the complex did not have keys for roof access and both maintenance techs were unavailable. Travis found a massive refrigerant leak in the condensing coil of the rooftop unit, which left the system operating with a significantly low refrigerant charge. He also located a refrigerant leak in the evaporator/indoor coil, and advised that both coils would need to be replaced (with system replacement recommended given the equipment's age), then left the rooftop unit turned off to prevent compressor damage. On another unit that was not cooling, Travis found the air filters completely packed with dirt and debris, severely restricting airflow, and removed them.
After the filters were removed, the temperature split improved from approximately 3°F to approximately 10°F and the unit was up and running with improved cooling.
Durham's diverse housing stock ranges from historic homes to modern builds, each requiring different HVAC approaches and solutions.
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.
Durham's tree-lined neighborhoods provide shade but also shed debris that can clog outdoor AC units, requiring regular cleaning and maintenance.

Common signs include: warm air from vents, system running constantly without reaching set temperature, ice on the refrigerant lines or evaporator coil, and higher than normal electricity bills. If you notice these symptoms during NC summer, call for a diagnosis promptly.
Unlike fuel, refrigerant doesn't get consumed. It circulates in a sealed system. Low refrigerant always means there's a leak somewhere. Simply adding more without fixing the leak is a temporary fix that wastes money and harms the environment.
R-22 production has been banned since 2020, making remaining supplies increasingly expensive ($75-$150+ per pound). Your options include repairing and recharging (short-term), converting to an R-410A-compatible system, or replacing with a new high-efficiency unit. We help you evaluate the most cost-effective path.
Costs depend on refrigerant type and amount needed. R-410A recharges typically run $200-$500. R-22 recharges can cost $500-$1,500+ due to scarce supply. We always provide a complete diagnosis and quote before performing any work.
