Thermostats and Sensors for HVAC Systems 

HVAC thermostats and furnace sensors are essential for regulating system performance, energy efficiency, and safety. These components monitor conditions such as temperature, pressure, and flame status, ensuring furnaces, air conditioners, and heat pumps operate correctly. Furnace Part Source offers a wide range of OEM furnace sensors and thermostats for both residential and commercial applications. 

Types of HVAC Thermostats 

  • Non-Programmable Thermostats – Manual models that maintain a set temperature until adjusted.
  • Programmable Thermostats – Digital controls with scheduling features to reduce energy usage during off
  • Smart Thermostats – Wi-Fi connected, app-enabled devices with advanced features like occupancy detection and zoning compatibility. 

Compatibility and Replacement 

Selecting the correct OEM thermostat or sensor ensures accurate readings and reliable operation. Always verify part numbers, voltage requirements, and system configuration (single-stage, multi-stage, or heat pump) before replacing components. 

Maintenance and Upgrades 

Faulty sensors can cause misreadings, wasted energy, or system shutdowns. Replacing worn parts or upgrading to energy-efficient thermostats restores system reliability, reduces utility costs, and extends equipment life. 

Wide Selection from Furnace Part Source 

With access to over 500,000 parts from 300+ manufacturers, Furnace Part Source provides the right solution for any repair or upgrade. From thermistors to programmable thermostats, our catalog includes components designed for both residential and commercial HVAC systems. 

Frequently Asked Questions 

What types of thermostats are available for HVAC systems? 

Options include non-programmable, programmable, and smart thermostats, each offering different levels of control and energy efficiency. 

How do I know if my furnace sensor needs replacement?

Signs include frequent system shutdowns, inaccurate temperature readings, or ignition failures.  

Why should I use OEM furnace sensors? 

OEM parts ensure proper fit, compatibility, and performance, reducing the risk of system malfunctions.

What is the difference between a thermocouple and a flame sensor? 

Thermocouples generate voltage to detect a pilot flame, while modern flame sensors use electronic signals to confirm burner ignition. 

Can upgrading to a smart thermostat improve efficiency?

Yes. Smart thermostats allow remote control, scheduling, and advanced optimization, often reducing energy costs.
