It is vital to properly maintain your heating and cooling systems in order to prolong the life of the units and to improve their efficiency. Air filters, in particular, need to be inspected on a monthly basis to check for any dirt or debris that could be clogging them.
Filters keep your systems operating properly and prevent the units from becoming dirty. The efficiency of an air filter is evaluated using the MERV rating system. MERV refers to the Minimum Efficiency Reporting Value. The filters are rated between 1 and 20. A high rating indicates a high level of efficiency. Look for replaceable pleated HEPA filters with a MERV 12 rating for the best results.
An air filter that is clogged will prevent the normal flow of air and significantly reduce the efficiency of your HVAC systems. The blocked air that contains dust and dirt particles can potentially flow into the evaporator coil. Dirt and debris in your evaporator coil can lead a number of possible problems with your system.
Make sure you also know the type of filter that your systems uses. There are disposable filters that can be easily replaced when they become filled with dirt and debris. You will need a replaceable that fits your system, so take the filter size with you when you go shopping for new ones. Other filters are manufactured to be washed when they become dirty. You will need to properly vacuum and clean the filter instead of replacing it. Check with the washing instructions provided by the manufacturer before you do any cleaning.
