I’m wanting to cool my house down as it gets really hot in summer (WA) but not sure if to choose roller shutters that I know will instantly cool the house down. The outlay is pretty huge but I know my house will be 50% cooler in the hotter months, and will keep winter warmth in. Do I do the whole house or will a few shutters be enough to cool the house down?
Aircon will be great but gives me instant increased power bills as I’ll need it to be on a lot in summer since the house gets really hot and uncomfortable. Then during winter for heating - reverse cycle ducted system is preferred which isn’t cheapest option either.
Which would be better for house resale?
