I’ve been a resident of the southwest for a few years now. Let myself and others just get this out of the way: yup, it is terribly moderate here for most of the year. The humidity is legitimately low in this region, so the heat tends to get much higher that it would in other regions of the country. Still, that’s not to say that this section is uninhabitable – you just have to suppose critically about how you’re combatting the dry heat! In the deep south, people have no option however to rely on forced central air conditionings that are supercharged with refrigerant. Additionally, those folks often rely on an air conditioning system that cools in addition to dehumidifies, as it is much easier to cool down a home with low humidity… You might suppose that southwestern homes cool down fast due to low humidity as well, however don’t be mistaken! The concern here is that the humidity is too low, so the solution is an a/c device that can also humidify the house. While homeowners here can buy both a central air conditioning system plus a humidifier, the better in addition to more cost-effective option might be a swamp cooler! Swamp coolers have 1 powered component, which is a blower that legitimately pulls outside air into the cooling system before sending it into the house. Since swamp coolers (or evaporative coolers) rely on the outside air in addition to cool, wet pads to chill in addition to dampen that air, this alternative air conditioning is a highly effective way to keep your desert home cool separate from spending a fortune.
