When your furnace lights up on a cold day or night in Midland, MI, the warm air it produces must pass through an air filter before reaching your rooms. Not only does this filter clean the air before it reaches your lungs, but it enables good airflow and promotes optimal heating performance. As a result, the HVAC professionals of All Seasons Heating and Cooling consider the filter to be one of the most important furnace components.


At All Seasons Heating and Cooling, we recommend that our customers regularly change the filters in their heating and cooling systems. Replacing the filter at least four times a year has a wide range of benefits, including better:

Airflow. One of the key performance indicators for any type of heating or cooling setup is the amount of air that can flow through the system. Airflow can be bottlenecked at several locations, but most often blockages occur at the air filter. By making sure the filter is clean, your furnace will be able to deliver warm air to your interior without working extra hard.
Indoor air quality. Filters are given a Minimum Efficiency Reporting Value (MERV) rating according to how small of particles they can trap. A filter with a high MERV rating will filter out most of the particles in the air you don’t want to breathe.
Furnace performance. When your filter is clogged, dirt and grime can build up on your furnace components, shortening its lifespan and causing it to work extra hard to push air throughout your home. When it’s clean, your furnace can heat optimally while maintaining its efficiency.

How often you need to change your filter will depend on the environment you live in, including any family pets you own. The more dust, dirt, fur and other particles that are in the air, the more often you’ll need to perform maintenance.


When a fully certified and skilled technician from All Seasons Heating and Cooling comes to change or clean your filters, they’ll also check for other problems that might affect the performance and efficiency of your furnace. We have experience working with all types of furnaces, and we can recommend you the best type of filter for your needs.

If you want your furnace to operate at peak condition for the lowest possible cost, regular cleaning or replacement of your filters is essential. Please contact us at All Seasons Heating Cooling today to schedule an appointment.
