A variable-speed motor is a component of high-performance residential furnaces and air handlers. Connected to fan blades, it moves air through your ductwork and into the different rooms of your home.
Unlike single-speed motors that run at full capacity and then cycle off, a variable-speed motor can operate at high speeds, low speeds or anywhere in between, ramping up and down like a dimmer switch. Because it can fine-tune airflow to heating or cooling demand, it minimizes wasted electricity and ensures money spent on utility bills goes directly into the comfort of your home.
Energy efficiency is just one advantage of a variable-speed motor. Gradual acceleration and deceleration of the motor significantly reduces sound levels, compared to a single-speed motor. This also helps keep temperatures more consistent. During summer months, a variable-speed motor can help your air conditioner or heat pump remove excess moisture from the air.
Lennox offers a variety of furnaces and air handlers with variable-speed motors.
