Heat wave: keeping your home cool and the AC running

Simple ways to keep the house cooler, and how to keep the AC from failing on the hottest day.

Tune up the AC in spring

AC calls spike in the first heat wave. A spring tune-up and clean coils prevent most breakdowns.

A clogged filter makes the AC work harder and cool less.

Close blinds on south and west windows in the afternoon.

Keep 60 cm clear around it and rinse off grass and dust.

A heat pump cools in summer and heats in winter, and rebates are often available.

What temperature should I set the AC to?

Around 25°C when home is a good balance of comfort and cost; raise it when you are out.

My AC runs but does not cool — what now?

Check the filter and breaker first. If it still blows warm, turn it off and book a technician — running it can freeze the coil.
