If you could pick only AC OR central heating, which would you pick if you lived in this climate.. (temp, days)

Easily AC. I'll be needing it almost every day from April to October and might need it even in January with that record high! Whereas I'd probably only need heating during some of the nights from November to March, and if it gets a bit cold then I can just wear extra layers. The warm winter days also help because it heats up the house in the daytime so it doesn't get quite as cold at night as it would if the average highs were in the 50s instead.

You must be very soft if you need AC from April-October here. Typical

It all depends on home construction.

Thick walls, give me AC.

Heat as only been on once this fall (5.9/-3.6) for me and currently indoor temp is 24c.

Heating -being cold is much more miserable than being hot.

Central heating does seem excessive for Glendale though -my climate is much colder during winter, but we only need to heat the main living area.

AC, and it's not even close because you can run the AC as a heat pump for cold weather. That's what we do here in Phoenix, use our AC for heat in the winter

I don't really like to use the AC either (we keep the thermostat on 83F or so in July), but heating is truly unnecessary in this climate.

Believe me, you need heat if MEAN temps drop below 16 Celsius for more than about 4 days. We use heat generally from just after Thanksgiving until early February here, when normal high temps range from 18.3° to 22.2°C and normal lows range from 5° to 10°C.

It sounds like you have a poorly designed house for retaining heat.

That's a big part of it, when our normal MEAN temp hit's 35.9°C in mid July, you don't want a structure that will retain heat.

Also, we get used to such hot weather in the summer, that we get sensitive to cold. I can't take indoor temps below 24°C, so that takes heat in the winter, as our normal high temp is below 24° from 11/23 until 3/5

May through October look pretty miserable in terms of high temperature so I'll have to pick AC.

Keeping warm during the cooler nights is less of an issue than trying to cool down during the hot summer/spring days!

Easily AC.

Glendale rarely gets that cold. Put a sweater on and you'll probably rarely even miss having heat. For those times you do, get a couple electric space heaters. It's not even cold enough to bother with a pellet or propane heater.
