Why you shouldn't forget about your furnace?


Airflow:

Like a heart, your furnace is responsible for keeping everything moving. Winter, summer, spring or fall, the furnace is pushing air through your ducts.

The type of fan motor your furnace uses can affect the comfort level in your home, and the amount of energy you use.

Single-speed motor(PSC): Operates at full blast, or not at all. Found in less efficient furnaces.

Constant Torque Motor:  Can adjust airflow based on heating or cooling need to maintain even circulation. Operates quieter on continuous fan speed and offers efficiency savings up to 33% more than standard single speed motors.


Variable-speed motor: Provides the highest level of comfort and energy efficiency.  Variable-speed motors can operate at high speeds, low speeds, and anywhere in between, ramping up and down like a dimmer switch.

The ECM (Electronically Commutated Motor) gives you increased comfort by accelerating and decelerating slowly, which eliminates sudden gusts of air. The soft start and the soft stop make it a quieter furnace.

Running your fan continuously removes cold spots in your home and gives you ideal comfort.

The lesser the humidity in the air the cooler you will feel. A big part of air conditioning is humidity removal and the variable ECM blower motor helps do that efficiently. It can fine-tune airflow to heating or cooling demand. They minimize wasted electricity and ensure the money spent on utility bills goes directly into the comfort of your home.
