In today’s fast paced society we often don’t think about common products or processes. We assume that anything we buy or use will operate as indicated and that we should be able to utilize the product with a minimum of effort and retraining. Our home heating/cooling system fits into that category. We turn on the heating or cooling cycle from our thermostat and expect the temperature in the home to match the temperature setting. We do this without much thought.
When the heating or cooling doesn’t cool or heat adequately we automatically contact our local HVAC contractor rather than even attempt to diagnose the problem by ourselves. While the problem maybe a major malfunction of a component, often times the reason for the lack of cooling or heat is a plugged air filter.
The blower/motor assembly on your HVAC system is rated at a certain motor horsepower and air flow, as measured in CFM. These are matched systems for the cooling coil and heating system based upon the size of the home. This includes the static pressure the fan sees to pull and push the air throughout the duct system. If the filter is plugged it will take more energy to pull the air through the filter and since the motor/blower assembly is designed to handle a limited amount of static pressure for the CFM it moves.
If the static pressure capability for the blower/motor is 1.5 ” at rated CFM capacity and the plugged filter adds another .5 to 1.0″ of static load ( which it can do ) it will significantly reduce the air flow through the system as much as 50%. That means it takes much longer to heat or cool your home and it also puts a strain on your system in total. And, it will significantly reduce the ability to remove humidity from the home. Checking the condition of your air filter on a regular basis should be part of your routine.
