Yes, a reverse-cycle heat pump works as an air conditioner in summer. In cooling mode, it removes heat from inside your home and releases it outdoors. If you already use a reverse-cycle heat pump in winter, switch the remote to Cool mode to use the same unit on hot days.
Will one heat pump cool my lounge and dining area?
One heat pump can cool an open-plan lounge and dining area if it’s sized for the space and positioned so air can reach both areas. Large windows that get afternoon sun, high ceilings and the shape of the room all affect what size you’ll need and where the indoor unit should go.
If your lounge gets particularly hot in the late afternoon, mention that when you book a quote. Closing blinds before direct sun hits the windows can also help reduce how much heat builds up in the room.
Will a lounge heat pump cool the bedrooms?
A lounge heat pump mainly cools the area it can move air through. Bedrooms down a hallway or behind closed doors may still feel warm, even when the lounge is comfortable. If sleeping comfortably is your main priority, tell your installer which bedrooms get hot so they can discuss options for those rooms.
