This can happen if the air filter is not changed on regular basis. With a clogged air filter the air will take path of least resistance which in most cases will bypass the filter through cracks or open crevices usually accumulating on the inside blower motor, wheel, and evaporator coil. When this happens it can cause a lot of problems such as high operating cost, refrigerant problems, and premature failure of equipment. Call us for an inspection of your Hvac system.
