Is your filter clean? You could be wasting money and energy right now. When is the last time you changed or even checked your air conditioning filter? The air intake, or return air grille, is analogous to your body's lungs. Poor respiration can lead to other serious problems. It's the same for your air conditioner, or furnace for those northern folks. In an air conditioner, the Freon running through the system depends on maximum air flow to exchange heat. An air conditioner or heat pump dissipates heat pretty much like your body. While perspiration is the body's way of losing heat, condensation is the process by which this occurs for your home cooling system. If the air used in this process is restricted, it takes the system longer to extract the heat becoming less efficient. So, what type of filter do you have? There are so many types of filters on the market these days it's hard to know what to buy. Here are a few.
The standard fiberglass filters are generally the cheapest and most common. This type traps only large particles of dust and lets smaller ones get through and into your system. Efficiency on these filters range from 7-12 % - meaning, of all the airborne particles in your household, this is the percentage caught by the filter. Costing around a dollar or so, you definitely get what you pay for. Eventually, the money you think you're saving on these filters will be spent on having a professional perform a thorough and expensive cleaning on your system.
