Effects Of Air Flow Restrictions On Your Ac System

Insufficient cooling and also home heating issues are frequently blamed on the system itself when the actual trouble can be poor/restrictive ductwork. For appropriate heating and cooling performance proper ductwork layout and sizing are necessary, to find an Orlando Ac Repair company watch the video below.

Air flow is the medium through which we move cool or hot air throughout area. The more air that is moved the cooler or hotter your home will be.

Proper air flow movement is a vital aspect to achieve optimum heating and cooling, inadequate air movement across its interior coil reduces its cooling ability and also the ability to remove more wetness from the air. Too much air movement raises its air conditioning ability but triggers it to remove even more sensible warmth and also much less dampness from the area.

Air flow restrictions can also cause havoc with ECM (electronically controlled motor) type motors. Air conditioning systems have become a lot more innovative with the use of ECM motors designed to change the RPMs in response to the demand. Unlike the older PCS type electric motors that ran at a constant Revolutions per Minute, the newer ECM electric motors perform at steady torque.

A frequently overlooked issue that would cause airflow restriction is a dirty or clogged filter. Most filters are designed to be replaced every thirty days however most are left in placed way beyond this time frame and get clogged with debris. A filter left in place to longer can become ineffective and debris will end up on the Evaporator coil which will restrict flow across the coil.

Steady torque enables these motors to sustain the torque delivered to the motor when outside static stress (ESP) is above advised and/or changes during system operation. ESP (the resistance to the motion of air) is increased when ductwork is undersized, inadequately built and/or full or dirt or debris. This increase in ESP puts additional stress on the ECM motor which in turn may cause premature failure.

So ... How many ECM motor modules have you changed in the past few years? Is it possible that frequent motor failures were not due to defective motors instead the issue may have been rooted in the duct work? And that the ESP of the older ductwork is too high because of bad design or a restriction of air flow and that these electric motors are running at a higher rate for prolonged periods of time creating additional stress on the motor.
