Thermostats
Thermostats are a critical control component in mobile HVAC systems, regulating compressor cycling and maintaining consistent cab temperatures across trucks, off-highway equipment, and specialty vehicles. Whether you’re servicing a heavy-duty truck, construction equipment, or an agricultural cab, the correct thermostat ensures reliable cooling performance and predictable system operation.
This category includes preset (fixed) thermostats and adjustable thermostats designed for mobile air conditioning and heating applications. Many models use capillary sensing to monitor evaporator temperature and control clutch engagement, helping prevent evaporator freeze-up while maintaining driver comfort.
Our thermostat selection covers common temperature ranges, capillary lengths, and mounting styles used in mobile HVAC systems. Each product page provides detailed specifications, factory numbers, and verified interchange references to help you match the correct thermostat to your application with confidence.
Use the filters to narrow by temperature range, capillary length, mounting style, or manufacturer. If you’re replacing an OEM thermostat or building a custom system, these thermostats are engineered for durability, repeatable cycling, and long service life in demanding environments.
