Why are Furnace Pressure / Transducer Switches Expensive?

Typical Pressure Switch Found in Gas Furnaces

Transducer Switches Found in Ultra Low NOX Furnaces

Furnace Pressure/Transducer switches can be relatively expensive due to several factors:

1. Precision and Reliability: Transducer switches used in furnaces often require high precision and reliability to ensure accurate measurements and safety. Components built for these purposes usually undergo rigorous testing and quality control 90% of these parts are brand specific meaning the manufacturer or contractor does not recommend using an aftermarket switch, which can contribute to higher production costs.
2. Regulatory Compliance: Components used in furnaces often need to meet specific industry standards and regulations to ensure safety and proper functioning most furnaces in Southern California that require an Ultra Low NOX furnace carry Transducer switches. Compliance with these standards can increase production costs, consequently raising the final price of the transducer switches.
3. Research and Development: Developing transducer switches capable of functioning optimally in furnace environments might require significant investment in research and development. These costs are often factored into the final product price.
4. Limited Market and Demand: Furnace transducer switches might not have a huge market demand compared to more common parts needed in your everyday broken heating system, leading to lower production volumes. Lower production volumes can drive up the cost per unit due to economies of scale – the more units produced, the lower the cost per unit.
5. Brand Wide Switch Failure: Furnace components are expected to be durable and long-lasting in demanding conditions. Since the first production of Ultra LOW NOX Furnaces some brands have not had the best of luck producing or providing reliable parts in their heating systems. Some big brand names are having furnaces break down and in need of a transducer switch in less than a year of their furnaces being installed causing a high demand – low supply issue. With some parts given an ETA of 2-7 weeks.

The combination of these factors, among others, contributes to the relatively higher cost of furnace Pressure / Transducer switches compared to more standard heating system components.

How Do You Know What Kind of Switch You Need?

Call your local heating and air conditioning company for further information. It is not recommended to replace one of these parts without further testing. These parts tell your Circuit Board/Motherboard that your “Inducer Motor” is running which is the very first motor that turns on when you turn your thermostat to heat. That motor exhausts all your flue gases out of your venting to the roof or side of your house. The average price to replace one of these parts depends on manufacturer pricing and availability and can range anywhere from $295 to $795.
