Air Conditioning Quote Check in Collaroy Plateau

Generally not. The elevated, set-back position reduces salt exposure. However, homes on the eastern escarpment with direct ocean exposure may still benefit from coated coils.

Ducted reverse-cycle with zone control is the most popular choice. Typical installations for a 4-bedroom home cost $10,000–$15,000 depending on zones and brand.

For a typical bedroom (10–15m²), a 2.0–2.5kW split system is sufficient. Living areas (25–40m²) generally need 5.0–7.0kW. Open-plan living/kitchen areas may need 7.0–9.0kW. West-facing rooms with afternoon sun exposure should size up by 0.5–1.0kW. A proper heat load calculation is recommended.

Both are excellent. Daikin Cora is the most popular split system in Australia with strong coastal-rated options and competitive pricing. Mitsubishi Electric MSZ-AP is known for exceptionally quiet operation — ideal for bedrooms. Both offer R32 refrigerant, Wi-Fi control, and 5-year warranties.

R32 is the current standard refrigerant, replacing R410A. It has lower global warming potential (GWP 675 vs 2,088), is more energy efficient, and requires less charge. Almost all new splits from Daikin, Mitsubishi Electric, Fujitsu, and Panasonic use R32.

Yes — we check zoning assumptions, duct condition notes, outlet counts, return air sizing, replacement scope, brand suitability, and whether the quote accounts for ceiling space, insulation, and electrical capacity.

We detect whether an ABN, ARCtick licence, and electrical licence are mentioned on the quote, and check their format. We recommend confirming via ABN Lookup, NSW Fair Trading, and the ARCtick register.
