Filters - Very Important


The blower fan in the HVAC system has to work harder to push air. When it’s working harder, it’s drawing more energy, leading to higher bills.  It’s also more likely to wear out from the strain being placed on the motor which means $$.
The difficulty in moving air means that your living areas may not get all the air they need. This means poor home comfort for you. 
Because the heated or cooled air can’t travel out of the furnace, heat pump, or air conditioner as easily, the system runs the risk of overheating or freezing up. If your system freezes up this will then cost you because you will not be cooling or heating and instead calling an HVAC professional. $$
The additional material on the air filter itself can provide a space for moisture to gather, encouraging the growth of mold or bacteria colonies, which can lead to poor air quality in your home.
Because air doesn’t circulate as quickly, particles can settle in ducts and on household surfaces when they’d usually be carried into the system and filtered. It’s a lot simpler to change your air filter than it is to schedule an appointment with a professional. Lack of filter change can result in an ongoing drain to your system efficiency and a long-term source of pollutants in your air supply.


It’s best to change your air filter every month or two, especially if you have pets or live in a high-pollen area (which welcome to South Carolina). Air filters are generally inexpensive, and changing your air filter is a simple task that doesn’t require a professional hand. In most cases, you should simply be able to slide the old filter out and slide a new one in.

Check your unit’s documentation to determine what size of filter you need, and what minimum efficiency reporting value (MERV) range the furnace should fall into. A high MERV filter with a very tight mesh may be too much for some units, resulting in a situation a lot like a clogged air filter, even just after you’ve changed it.
