Was the room actually assessed?
A quote based only on floor area can miss glass, sun and ceiling height.
Ask this: How did you work out the capacity for this room?

Air Conditioning Ramsgate Choose the Right System First Time
Ramsgate stretches from Rocky Point Road down towards the bay, with brick family homes, duplexes and units in between. Whatever you live in, the most common air conditioning mistake we see is a system that is the wrong size for the room.
Updated October 2026
Air conditioning in Ramsgate works best when the system is matched to the room. Too small and it runs flat out without ever getting comfortable. Too big and it cycles on and off, wasting power and leaving the air clammy. We size every system from the room itself, then recommend the type that suits your home. We have been sizing and installing systems in Sydney's south since 1989.

Ramsgate FAQs
Ramsgate Air Conditioning Sizing Questions
What happens if my air conditioner is too small?
It runs at full power for long periods, struggles on hot days and wears out sooner, while never quite reaching the set temperature.
Can an air conditioner be too big?
Yes. An oversized unit cools quickly then switches off, cycling often. That wastes power and leaves the air feeling damp.
How do you work out the right size?
We look at room size, ceiling height, windows, orientation, insulation and how the room is used, then recommend a capacity.
Is a split system or ducted better for my home?
Splits suit one to a few rooms. Ducted suits whole-home comfort where there is enough roof space. A multi-split sits in between.
What warranty comes with a Daikin system?
Five years of parts and labour cover applies to Daikin systems we supply and install.
Do you hold the required licences?
We do: ARC licence AU54289 and NSW contractor licence 329810C.
