Air Conditioning Repair Sugar Land Two-stage Variable-speed carrier Gas-Firedfurnace








The 58CTW variable-speed, two-stage, 4-way multipoise gas furnaces offer unmatched comfort in their class with ComfortHeat Technology in an 80% AFUE gas furnace. You get the benefits of a

ComfortHeatTechnology furnace: reduced drafts, reduced sound levels, longer cycles, less temperature swing between cycles, and less temperature difference between rooms. Its exclusive, intelligent microprocessor control adapts to the heating needs of the home by automatically adjusting high and low heat times to maximize comfort. The 58CTW furnace is approved for use with natural or propane gas and uses the Comfort ECM blower motor for variable-speed comfort. The 58CTW furnaces feature:

Pulse Width Modulation (PWM) Motor
Pull out all the stops with the PWM-ECM blower motor. Rather than using five discrete setpoints for fan speeds, a PWM motor works through programming. Each time the controller switches a stator winding on and off, it is called a Pulse. The length of time each pulse stays on is called the Width. By varying the pulse width, the controller varies the motor speed (or, “Modulation).
