About ducted air conditioning
Ducted reverse cycle cools and heats the whole house through ceiling or floor vents, with zoning so you only run the rooms you are using. Design matters more than brand: return air placement, duct sizing and zone layout determine comfort and running cost. Expect a site visit before any serious ducted quote, and be sceptical of one priced from a phone call.
Getting quotes in St Marys
When you enquire about ducted air conditioning, describe the job specifically: what is happening, how long it has been going on, and anything you have already tried. Specific enquiries get accurate quotes; vague ones get a callout fee and an on-site surprise.
Local knowledge counts
Because aircon technicians in the Southern Suburbs region tend to group nearby jobs, flexible timing works in your favour in St Marys: if the work can wait a day or two, say so and ask whether that changes the price.
Quick answers
What size air conditioner do I need?+
As a rough guide, allow about 120 to 150 watts of cooling per square metre: a 20 square metre bedroom suits roughly 2.5kW, an open-plan living area often needs 7kW or more. Ceiling height, insulation, window area and orientation all shift the calculation. A good installer sizes from the room, not from what is on special.
Do aircon installers need a licence?+
Yes. Anyone handling refrigerant needs an ARC (Australian Refrigeration Council) licence, and the electrical connection must be done by a licensed electrician. Unlicensed installs void manufacturer warranties and can be unsafe. Ask for the ARC number; legitimate installers print it on their paperwork.
How often should aircon be serviced?+
Clean the filters yourself every couple of months in heavy use, and book a professional service roughly once a year, ideally in spring before installers hit peak season. Rentals and offices with all-day run time justify six-monthly servicing. Neglected units cost more to run every single hour.
