How to Choose the Best Air Conditioning & Heating in Lonsdale
A checklist before hiring any air conditioning & heating in Lonsdale, Adelaide.
- 1
Confirm they are a licensed refrigerant handling contractor (ARC licence) — required by law for any work on refrigerant-based systems.
- 2
Ask whether they service all major brands or are aligned with one manufacturer — brand-agnostic technicians often provide more objective advice.
- 3
Get a written quote that specifies the exact make, model, capacity (kW), star rating, and warranty of any unit being installed.
- 4
For ducted systems, ask for a room-by-room heat load calculation — undersized systems run continuously and fail early.
- 5
Confirm the quote includes the disconnect/reconnect of power and any required electrician attendance, which is a separate cost with some operators.
FAQs — Air Conditioning & Heating in Lonsdale, Adelaide
How much does ducted air conditioning cost to install in Australia?
Ducted reverse-cycle air conditioning typically costs $6,000–$15,000 installed for a standard 3–4 bedroom home, depending on the number of zones, brand, and access difficulty. Split systems cost $800–$3,500 installed per unit.
What size air conditioner do I need for my room?
A rough guide: 1kW per 10m² for standard rooms. A 20m² bedroom needs ~2–2.5kW, a 40m² open plan needs ~4–5kW. A qualified HVAC technician will perform a proper load calculation accounting for insulation, ceiling height, and sun exposure.
How often should air conditioning be serviced?
Residential split systems should be serviced annually — clean filters, check refrigerant, inspect coils and drainage. Ducted systems and commercial units need servicing every 6–12 months depending on usage. Regular servicing extends lifespan and maintains energy efficiency.
What is a reverse-cycle air conditioner?
A reverse-cycle air conditioner provides both cooling in summer and heating in winter using a heat pump. It's the most energy-efficient heating option for most Australian climates, and is 3–5x more efficient than electric resistance heaters.
How long does a split system air conditioner last?
A quality split system air conditioner lasts 10–15 years with annual servicing. Inverter models tend to outlast fixed-speed units. Brands like Daikin, Mitsubishi, and Fujitsu generally have strong reliability records in Australian conditions.
