Why Won't My Older Apartment AC Keep Up in Knightdale?
What the customer reported
Property managers at a Knightdale apartment reported that the unit was not cooling, and the resident was having difficulty maintaining the desired temperature. The managers could not figure out what was wrong with it.
What we found and did
Across three visits, the cause came into focus: the inside coil had heat rust build-up and was eventually found to be completely rusted, with high superheat. On the first visits, Travis checked supply air temperature and airflow and confirmed the system had been serviced the previous week, when the refrigerant was recovered and recharged. He noted the unit was approximately 17 years old and working harder under extremely high outdoor temperatures, with the apartment holding at approximately 68-70°F at the time. When the system was reported not cooling again, a follow-up check found the superheat high and the coil completely rusted, and replacing the coil with a TXV was recommended.

System Inspections in Knightdale: questions answered
Answered by our licensed technicians serving Knightdale.
How often should I have my HVAC system inspected?
We recommend a professional inspection at least once per year. Ideally, have your heating system checked in fall and your cooling system checked in spring, before each season of heavy use.
What is the difference between an inspection and a tune-up?
An inspection is a diagnostic evaluation that identifies problems and rates system health. A tune-up includes the inspection plus hands-on maintenance like cleaning, lubricating, and adjusting components. We offer both.
Can an inspection help me decide whether to repair or replace my system?
Yes. Our inspection report includes an efficiency rating and remaining useful life estimate, giving you the data you need to make an informed repair-vs-replace decision.
Do you inspect ductwork as part of a system inspection?
Yes. We measure static pressure, check accessible duct connections for leaks, and evaluate overall duct design. For a full duct assessment, we also offer dedicated ductwork inspections with airflow testing.
Will the inspection disrupt my home?
No. A standard HVAC inspection is non-invasive and typically completed in 60 to 90 minutes. We work cleanly and will not disassemble anything without discussing it with you first.
