Local considerations
Older ductwork in Wilmington homes often runs through spaces not designed for it, creating more leakage points and more surface area exposed to unconditioned air. The duct system is worth inspecting separately from the equipment.
Refrigerant work anywhere in Wilmington is restricted to technicians holding EPA Section 608 certification. If a provider is recovering or charging refrigerant on your system, they are required to hold it and you can ask to see it.

What is your thermostat reading?
Drag the dial to the temperature your thermostat shows now. The readout names the likely cause band, how urgent it is, and which page to read next.

- Likely cause band
- Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.

- AC not cooling
What to do while you wait
- Set the thermostat to off so the system stops cycling against the fault.
- Clear leaves, grit and debris from the outdoor unit so air can move through the coil.
- Replace the filter if it is visibly loaded. Airflow problems often start there.
- In extreme heat, move pets and anyone vulnerable to the coolest room and keep fluids nearby.

Wilmington HVAC questions
Why is my AC running but not cooling?
The three usual answers are restricted airflow, low refrigerant charge from a leak, or a failed capacitor stopping the compressor from starting. A technician separates them with a static pressure reading and a superheat measurement.
Can I get maintenance rather than a repair?
Yes. Maintenance visits cover coil cleaning, condensate drain clearing, filter replacement and a capacitor check. These are booked rather than dispatched as emergencies, and they typically cost less than a repair call.
What does AC repair cost in Wilmington?
We do not quote prices. The provider who attends inspects the system, tells you what the work costs, and confirms that figure on site before starting. Refrigerant leak work generally takes longer than a straight part swap.
How long does a cooling repair take?
Most repairs finish in a single visit of one to three hours once the fault is diagnosed and the part is on the truck. Components that have to be ordered, such as a specific control board, add a day or more.
How do you choose which provider gets my call?
By ZIP code first, then by which providers are accepting calls at that moment. We do not rank providers by price or sell placement in a results list, and we do not publish ratings of any kind.
