The sizzling temperatures of summer are approaching, and soon your air conditioner will be operating around the clock. Air filters are located in the air handler or on the return ducts entering your unit. The constant use of your air conditioner will dirty and clog the unit’s air filter, which catches dust, dirt and pollen before it enters your system. That’s why it’s essential to inspect and replace your air filters regularly.
Types Of Filters
- A flat-panel filter is often made of fiberglass, comes in different thicknesses and used in older air conditioners. The thicker the filter, the more material it will remove from the air.
- A pleated filter is used in newer systems, creates a greater area to collect pollutants and is more efficient than a flat panel filter.
- MERV (minimum efficiency reporting value) is a standard used to evaluate the efficiency of filters. Check the manufacturer recommendations for the correct rating for your filters or call a local HVAC dealer for information.
- The size and thickness of filters depend on the manufacturer’s requirements. Most filters come in standard sizes, but some filters are custom made and must be replaced by a professional technician.
Damage From Clogged Filters
- Pollen and dust will remain in the air and flow through the system, aggravating health issues for family members with allergies or asthma.
- Dirt accumulating on the evaporator coils will act as insulation and hinder the performance of your unit.
- Dust and dirt not caught by the filter will gather in the ducts and flow into your rooms.
- A clogged filter will restrict airflow, increase energy costs and create expensive repair bills if the unit shuts down.
As a homeowner, follow the recommended guidelines from the manufacturer and obtain a filter with the highest level of efficiency for your air conditioner. Consider contacting a specialized technician to evaluate the condition of your filters and make recommendations.
