Imagine this scenario: It’s the middle of summer and you’re sitting in your home on an 85° day. It’s okay that it’s that hot because your air conditioner is blasting away, providing you with chilled air that makes you feel perfectly comfortable. Until suddenly, the AC stops working.
You rush to the thermostat—the settings are correct. The thermostat still seems to be functioning, so what gives? Next you check to see if the circuit breaker to your AC tripped and needs to be reset—nope, it’s not that either. You call for emergency repairs—but you have to wait for service since after all, it’s the middle of summer, and everyone else is calling for emergency AC repairs too.
