Answers About HVAC Service
in Raleigh & the Triangle
AC repair costs in Raleigh, NC typically range from $150 to $600 depending on the issue. Common repairs like refrigerant recharges run $200–$400, while component replacements (capacitors, contactors) are often $100–$300.

Custom Air Conditioning has been serving the Raleigh Triangle area since 1981 — over 45 years of continuous family-owned operation. As one of the longest-established HVAC companies in the region, we have built generations of trust with homeowners and businesses across Raleigh, Durham, Chapel Hill, and Cary. Longevity in this business isn’t luck — it’s what happens when you do the work right, every time.
In North Carolina’s hot, humid climate, air conditioners should be professionally serviced once a year — ideally in spring before the summer heat peaks. Given the heavy cooling load NC summers place on HVAC systems, annual maintenance helps prevent mid-season breakdowns, maintains efficiency, and extends the life of your equipment by several years. Ask us about our preventative maintenance programs for year-round peace of mind.
A professional AC maintenance visit from Custom Air Conditioning includes: inspection and cleaning of the evaporator and condenser coils, checking refrigerant levels, inspecting and lubricating moving parts, testing electrical components and connections, thermostat calibration, ductwork inspection, filter inspection, and a full system performance test. This helps catch small issues before they become costly repairs — especially important heading into a Triangle-area summer.
Signs you may need AC replacement rather than repair include: your system is 15+ years old, repair costs exceed 50% of a new unit’s price, you need frequent repairs year after year, your energy bills are rising despite normal use, or your system uses older R-22 refrigerant (now discontinued). If your unit is newer and the issue is a single component, repair is usually the better value. We’ll give you an honest assessment — call 919-781-1789.
