These units have plenty of moving parts, including the air handler which distributes air throughout your home, the evaporator coils that cool the air, and the filtration system that keeps your air quality comfortable.

Different types of HVAC systems have different components, but it’s important to understand what is the brain behind every single one of their operations: the thermostat. The thermostat will act accordingly to whatever temperature you set it to.

Most thermostats use a bimetallic element that expands and contracts as the temperature changes within your home. Older thermostats have two exposed bimetallic contacts that bend to make contact as the temperature changes in your home, where modern thermostats are unexposed and uncoil as the temperature changes.

The Importance of Ongoing Maintenance
