The Importance of Routinely Changing HVAC Air Filters
One simple yet necessary task to keep an HVAC system running smoothly is changing the air filter. As the air is pulled into an HVAC system, it passes through an air filter. When that filter becomes clogged by the dirt and debris being trapped in it, it can create all sorts of problems.
Clogged air filters can cause several issues, including:
- Restricted airflow leading to diminished comfort
- Frozen condenser coils resulting from dirt buildup
- Poorer indoor air quality from circulation of contaminants
- Increased utility bills because of more electricity being used to operate the system
- Reduced system lifespan due to the unit working harder than it needs to
Changing an air filter is the cheapest, simplest form of maintenance for an HVAC system. When an air filter is clean, it’s capable of doing its job: trapping the debris and preventing it from entering the HVAC system. A cleaner HVAC unit ultimately means fewer repairs and a longer unit lifespan.

HVAC Fan Motor Gone Bad?
An HVAC system is composed of many parts. One of the most important components is the fan motor – it’s often regarded as the “heart” of the equipment. The fan is responsible for circulating conditioned air throughout the home. A faulty fan motor can have a serious impact on the comfort of a home and can decrease the lifespan of the HVAC system.
The biggest problem encountered by fan motors is dirt buildup. When dirt accumulates on the fan motor, it can cause the part to overheat. By scheduling routine HVAC maintenance, an HVAC technician can check that the fan motor is clean and in good overall shape. During the maintenance appointment, we can inspect other motors within the HVAC system, including compressor motors, inducer motors, and condenser fan motors, as well as all of the unit’s capacitors.
