SetMyTemp
What temperature to set your heating in Phoenix today
Setting your thermostat to a fixed number doesn't guarantee the same comfort every day in Phoenix. When it's colder outside, the walls and windows of your home cool down and radiate cold, so you feel chilly even at a “normal” setting. SetMyTemp reads the live weather in Phoenix, United States — temperature, humidity and wind — and tells you the setting that actually feels right, right now.

How it works
SetMyTemp uses the recognised thermal-comfort model (PMV / ISO 7730). It estimates how cold your walls are given the outdoor temperature, factors in humidity and wind, and works back to the air temperature you should set to feel neutral — then runs that quietly in the background so you just get a clear number.
Frequently asked questions
- What is the ideal heating temperature in Phoenix?
- There is no single fixed number: the right setting depends on today's outdoor temperature, humidity and wind. On a cold, windy day you need a slightly higher setting than on a mild day to feel the same comfort. Use the live recommendation above.
- Why do I feel cold even when my thermostat reads a normal temperature?
- Because comfort depends on more than air temperature. Cold walls and windows pull heat from your body by radiation, so you feel cold even when the air is warm. SetMyTemp accounts for this.
- Can I save energy with the right setting?
- Yes. SetMyTemp also shows an “eco” setting — slightly cooler but still acceptable — so you don't overheat your home and waste energy.
