How much does aircon installation cost in Penang?

A single split-unit installation in Penang costs RM 1,400-2,600 for a 1HP unit and RM 2,400-4,200 for a 2HP unit, all-in with copper piping, trunking, bracket, and commissioning. Multi-split systems run RM 5,500-8,500 for two zones and RM 10,500-16,000 for four zones. Ducted systems for 3-4 rooms start at RM 14,000-22,000 before ceiling work.

What is the difference between split-unit, multi-split, and ducted aircon in Penang?

A split-unit has one outdoor compressor serving one indoor head — the most common Penang install. A multi-split has one outdoor compressor with two to four indoor heads, cheaper than separate splits when zones are close together. A ducted system hides the indoor unit in a ceiling void and serves multiple rooms through concealed ductwork; it only makes sense during a full renovation when the ceiling is already being rebuilt.

What extra costs push a Penang aircon installation quote higher?

Three main factors: extra copper piping beyond 4-5 metres (RM 35-80 per metre; Penang shophouses often need 8-12 metres because the compressor is at the rear courtyard), concealed trunking chased into walls instead of surface-mounted (adds RM 600-1,500 per unit), and coastal-spec compressors for seafront properties in Batu Ferringhi or Tanjung Bungah (adds RM 200-600 to the unit cost).

What HP aircon do I need for a Penang room?

A quick rule for Penang's hot-humid climate: 1.0HP for bedrooms up to 100 sqft, 1.5HP for master bedrooms 100-180 sqft, 2.0HP for living rooms 180-280 sqft, and 2.5-3.0HP for open-plan rooms above 280 sqft. Over-sizing causes muggy rooms (the unit cools fast but doesn't dehumidify); under-sizing runs the compressor hot and shortens its life to 3-4 years.
