What do Switches do in an HVAC System?

Within an HVAC setup, switches play a crucial role in managing the system's operations, including the initiation and cessation of the system, fine-tuning of temperatures, shifting among various modes like heating, air conditioning, and fan, and determining the fan's intensity. This array of controls allows residents to adjust the indoor atmosphere to their preferred comfort level and enables the activation of additional features such as energy-efficient modes, timed automatic functioning, and the improvement of air quality through advanced filtration and circulation features.

What are the Different Types of HVAC Switches?

Within an HVAC system, you'll find two critical types of switches: pressure switches and temperature limit switches. The former closes an electrical circuit at a specific pressure point to ensure safe operation, while the latter controls the system's heating or cooling by triggering at a set temperature limit.

What are Pressure Switches Used For?

Pressure switches are used in HVAC systems to help regulate the pressure within a compressor. This is done to ensure that your HVAC system won’t reach an unsafe pressure while it’s operating.

What is an HVAC Float Switch?

An HVAC float switch—a.k.a. AC safety switch and condensate overflow switch—is used to help prevent an overflow in the drip pan if there is an issue with the AC drain.
