After air conditioning in Smithfield? Jay's Air has been doing it since 1991. A 2.5kW split for a bedroom runs $1,800 to $2,100 installed, a 5kW living room unit $2,500 to $3,000, and whole-house ducted lands at $7,000 to $11,000 where the roofline suits. Fault-finding is $250 plus GST with the fix quoted before we start. 4.8 stars from 280+ reviews.
The honest rule we run everywhere: under $600 on a system under 15 years, repair it. Past both, the money does more in new gear - especially old R22 units with the gas at $265 a kilo.
Big households work systems harder
Plenty of Smithfield homes run multi-generation households, and the aircon maths changes: systems running most of the day, multiple rooms cooled at once, and granny flats out back needing their own units. Sizing for the real usage - not just the floor plan - is what keeps the bills sane and the gear alive.
Granny flat installs are weekly work here: a dedicated 2.5kW split at $1,800 to $2,100 beats extending anything. Numbers first: the sizing calculator and the pricing guide.
Smithfield sits on our Fairfield run with Fairfield, Fairfield West and Merrylands.
