When Thermostats Go Bad!

Sounds a touch dramatic, but we want to make a point about how important your home’s thermostat is for the overall operation of your HVAC system.

The temperature differential for residential ACs is 20°F.

For example, a small window AC can remove about 5,000 BTUs/hour from a space, but this is only enough to cool down a single room. Larger central ACs can remove 12,000 to 60,000 BTUs/hour.
