Partly to avoid that possibility, the furnaces in most homes are larger than necessary. Initial cost is only one of the drawbacks of that strategy. A furnace that's too large will cycle on and off more frequently. That puts more wear on its components, wastes energy, and might cause the temperature to vary uncomfortably. Also, a larger replacement furnace might require larger ducts. Without the right size ducts, airflow can be noisy.
If you own a forced–air distribution system, then you need to ensure that you take care of your ductwork. After all, your central AC or heat pump is only as effective and efficient as the cleanliness and integrity of the ducts that transport your conditioned air. With our air duct cleaning service in Federal Way, WA, your HVAC system is in good hands.
Cleaning the debris that builds up on your filters will aid with the flow of air. When your air filter is clogged, your air handler must work harder to compensate for the blockage of air flow. In addition to driving up your utility bill, the reduced air flow through your heating and cooling system can cause your heat exchanger to overheat and shut off too quickly.
