Split system installation & service in Mordialloc
Mordialloc 3195 · About fifteen minutes from our Bentleigh base.
From the creek to the Nepean Highway shops, Mordialloc mixes bayside homes with busy small businesses. We install and service single split systems for both — including commercial units up to 18 kW for cafés and shopfronts where cooling is part of the trading day.
We’re True Line Air Conditioning, the air conditioning division of True Line Electrical, based in Bentleigh and servicing southeast Melbourne.

Mordialloc questions, straight answers
How quickly can you install a split system in Mordialloc?
About fifteen minutes from our Bentleigh base. Standard service calls in Mordialloc are same-week, and installs are usually booked within days of your free measure — we confirm the timing in your written quote. Care plan members get next-day priority.
Does salt air affect outdoor units in Mordialloc?
Close to the bay it does — salt-laden air corrodes coils and fins faster than it would further inland. Two things help: positioning the outdoor unit thoughtfully at installation, and an annual service that includes a proper coil clean and corrosion check. Both are part of how we work — placement is decided at your free measure, and every Trueline Care install includes its first year of servicing.
What does split system installation cost in Mordialloc?
The same as everywhere we work — our prices are published, with no suburb loading. Installation starts at $2,399 fully installed (inc GST) for a 2.5 kW Essential package, back-to-back on a single storey. The full table and a 30-second estimate for your rooms are on our homepage.
