Not sure what’s wrong? Here’s what your symptoms usually mean, and what to do nextBlowing warm air, not cold
Usually a low refrigerant (gas) level from a slow leak, or a dirty filter restricting airflow. A quick filter clean is worth trying first.
Dripping or leaking water indoors
Almost always a blocked condensate drain pipe or a failed condensate pump. Less commonly, it means the unit is low on gas and icing up before melting.
Making a loud or unusual noise
Rattling or vibrating often means a loose panel or fan blade. Grinding or squealing usually points to a worn fan motor bearing.
Won’t turn on at all
Check your circuit breaker and remote batteries first. If those are fine, it’s likely a tripped isolator switch, blown capacitor, or wiring fault.
Just needs a routine clean or re-gas
No obvious fault, but the aircon feels weaker than it used to, or it’s been 6–12 months since the last service. This is normal wear and fully preventable.
Load shedding damage or won’t restart after power cuts
Frequent power surges from load shedding can trip compressors or damage circuit boards over time. A surge protector is a cheap way to prevent this.

What Size Aircon Do You Need?
A quick guide to choosing the right BTU rating for your Pietermaritzburg room or office| Typical Room Type | Approximate Floor Area | Recommended Aircon Size |
|---|---|---|
| Standard Bedroom | 12 – 15 m² | 9,000 BTU |
| Main Bedroom / Small Lounge | 15 – 20 m² | 12,000 BTU |
| Large Living Room | 20 – 30 m² | 18,000 BTU |
| Open Plan Area | 30 – 40 m² | 24,000 BTU |
| Large Commercial Space | 40 – 60 m² | 30,000 BTU |
These are general guidelines — ceiling height, sun exposure, and how many people use the room all affect the right size for your Pietermaritzburg home or business. We recommend an energy-efficient inverter unit over a standard non-inverter model for lower running costs, especially with load shedding in mind. We offer free on-site assessments to confirm the correct unit before you buy.
