Common causes and what they mean
| Cause | What it means |
|---|---|
| Dirty air filter or coils | Restricts airflow and forces the system to work harder — the first thing we check. |
| Low refrigerant charge | Usually indicates a leak that must be located and repaired, not simply topped up. |
| Failed capacitor | A very common and inexpensive failure that stops the compressor or fan starting. |
| Blocked condensate drain | Causes water damage around the indoor unit. |
| Thermostat or control fault | We verify wiring and calibration before touching the mechanical side. |
Types we service
- Central air conditioning systems
- Ductless mini-split systems
- Heat pumps

Before you book: have the brand and model number ready if you can find it — usually on a sticker inside the door, behind a drawer or on the rear panel. It lets us bring the right part on the first visit rather than the second.
