It used to be that the brains were analog. These days they’re digital and regulate your home’s body temperature much like your own brain.

The thermostat automatically switches heating or cooling devices on or off, or regulates the flow of a heat transfer fluid as needed, to maintain the correct temperature.

We all know the wall thermostat that controls your air conditioning and heating system, but thermostats can also be component parts of a heater or air conditioner that regulates the internal temperature.

All thermostats use a variety of sensors to measure and maintain the temperature. Al’s technicians are licensed and trained to install these little brains and repair and maintain the tiny sensors that govern them.
