Even the best equipment can falter—whether it’s improperly maintained or has simply suffered a rare malfunction.

Circuit Boards

While they are well-protected, circuit boards can be fragile components of Lennox HVAC systems. As a result, they are occasionally prone to failure. If the thermostat is functioning but is unable to communicate with the motors, burners, or other components, a faulty board could be the problem with your customer’s HVAC unit. We have OEM replacements designed for quick and easy installation.

Motors, which represent some of the larger Lennox HVAC parts that we carry, ensure that the blower and venter fans rotate at peak efficiency whenever they receive instructions from the control board. If they have worn down or experienced another issue, you’ll need to find the right replacement component for your customer’s system.

Blower Wheels

Blower wheels help regulate how much air moves into and out of a furnace system. When an HVAC unit is used continuously, particularly in commercial or industrial operations, these wheels are frequently clogged by debris and other contaminants. If your customer is concerned about reduced efficiency, you might need to replace the blower wheel to ensure the system operates properly.
