The quoted price for the same brand and size unit can vary by thousands depending on these three things.
Bigger rooms need bigger units. High ceilings lose heat faster and need more capacity. This is the single biggest driver of price variation within a system type. Getting the sizing right means measuring properly, not guessing.
A simple back-to-back install where the outdoor unit goes directly through the wall is the most affordable. Long pipe runs, second-storey access, concrete or brick walls, and difficult outdoor unit positions all add time and cost.
Premium brands like Mitsubishi Electric and Daikin cost more upfront than budget options but run quieter, last longer, and hold their efficiency better over time. For the older villas and bungalows common across Mt Eden and the surrounding suburbs, getting the spec right matters more than saving a few hundred dollars upfront.
Most installs are straightforward. But depending on your home, some of these may apply. My Mt Eden specialist identifies all of these on the site visit and includes them clearly in your quote before any work begins.
