Air conditioners work hard during the peak months of sweltering summer and cold winters to keep you cool as well as cozy. For making your HVAC system in optimal working condition, homeowners need a high level of maintenance. Air conditioners and furnace system not only produce cool or warm air, but it also maintains a germ-free and fresh internal environment. It is highly advisable to change the air filter once a month or on a bi-monthly basis.

In addition, if you are living in an area that is more prone to construction works, or having pets especially cats in the house would also contribute to dirty airways in your HVAC’s filter faster than normal. Any air filter that is clogged results in reducing the amount of airflow, causing your unit to work harder and affects your system efficiency.
