Our A/C keeps turning off. Mum had it serviced today and expected to be told we need a new unit.
She was right, 5k for a new A/C as its probably about 25 years old now. I don't exactly know when they bought it, I wasn't taking any notice. Price includes installation and they also putting a ceiling fan in the roof in her room.
New A/C and new insulation means next summer should be a little cooler.
Old one is approx 12 years old, I found its model number.
New one:
knew it, wifi connected. And has an app.
In the US, those are known as mini-splits, which are more efficient than what most Americans use. Because of the way houses used to be heated in the US, every house is basically built with a duct system, which makes Central HVAC very cheap to install.
The efficiency isn't a huge deal because American homes have always been built to retain temperature. Insulation levels are more than double in the US. Floors are insulated. Windows are typically triple pane, while Australian houses usually are single pane.
This is largely because in the US, almost every foot of earth is inhabitable, and only 40 percent of people live in coastal areas whereas it's over 80 percent in Australia. This makes temperature extremes greater in the US than in the average residential area in Australia.
For instance, summer highs in Sydney average 79f and average low in winter is 47f. Perth has the largest swing of the Australian cities I checked. It ranges from an average summer high of 89 to a low of 46. Meanwhile, Chicago goes from 84 to 18, Minneapolis from 84 to 9, Phoenix from 106 to 46. (Apparently a lot of people consider that habitable. I'm not in that group.)
The US and Australia have the largest home sizes in the world. I think Australia edges out the US by 4 square feet, so they are essentially identical. But US homes tend to be very compartmentalized. From what I understand about Australian homes, it's fairly common for the non-bedroom/bathroom areas to be one large area, which helps airflow, while in the US, all of those are individual rooms.
Apologies. I just got curious and did some research.
