Clean HVAC Filters: 7 Things Facility Managers Should Know 

June 12, 2024

Preventative maintenance is key to facility management, especially in the hot summer months.

As the temperatures rise and facility managers look to maintain total comfort for their customers and employees, one important yet overlooked task is regularly maintaining and replacing HVAC system filters.

While it might seem like a minor detail, ensuring clean air filters, either quarterly or semi-annually, is critical to maintaining a facility’s comfort level and financial health while reducing downtime and disruptions to operations – especially when the mercury is rising.

Here, the TCG team outlines seven reasons why facility managers should prioritize the regular replacement of HVAC filters.

1. Improved Air Quality

The primary function of HVAC systems is to maintain a comfortable indoor environment. Central to this function is the air filter, which traps dust, pollen, and other airborne particles and prevents them from circulating through the facility. Over time, these filters can become clogged with contaminants, significantly reducing their effectiveness.

Poor air quality can lead to a range of problems. Employees and tenants may experience allergies, respiratory issues, or general discomfort, leading to increased sick days and decreased productivity. Moreover, high MERV-rated filters (MERV 13), as outlined by the U.S. Environmental Protection Agency, are non-negotiable in environments where cleanliness is paramount, such as healthcare facilities or food processing plants. Additionally, charcoal filters are often used in restaurant facilities to help eliminate odors. 

In short, clean air filters effectively remove pollutants and allergens from the indoor environment, promoting a healthier environment for occupants. 

2. Enhanced System Efficiency

A clean air filter allows for unobstructed airflow, enabling the HVAC system to operate efficiently. When filters are dirty or clogged, the system must work harder to push air through, which can lead to increased wear and tear on components. This not only shortens the lifespan of the HVAC system but also leads to higher energy consumption.

Energy efficiency is a significant concern for facility managers and commercial property owners, as heating and cooling account for a substantial portion of operational costs. According to the U.S. Department of Energy, replacing a dirty, clogged filter with a clean one can lower an HVAC system’s energy consumption by 5 to 15 percent. 

Clean filters help the HVAC system run more efficiently by maintaining optimal airflow, reducing energy consumption, lowering utility bills, and supporting a more sustainable operation. 

3. Cost Savings on Repairs and Maintenance

While air filters themselves may seem like a minor part of your overall HVAC system, neglecting them can lead to costly repairs and prolonged downtime. 

A clogged filter, for example, makes the system work harder, which can lead to overheating and increased wear and tear on components. Built-up dust and debris inside an HVAC system with dirty filters can damage critical components like the blower motor, fans, compressors, or coils. This often causes parts to fail prematurely and leads to expensive repairs or replacements. 

Facility managers and commercial property owners who regularly replace their filters and maintain their HVAC systems are less likely to experience breakdowns, ensuring consistent operation and reducing downtime. 

4. Compliance with Health and Safety Regulations

As mentioned in item one, many commercial properties must comply with stringent health and safety regulations, particularly those in sectors such as healthcare, food service, and manufacturing. 

Under these regulations, regular replacement of HVAC filters is often a requirement to ensure a safe and healthy environment for employees, customers, and guests.

Regular filter changes help facilities comply with industry regulations where applicable, avoiding hefty fines and ensuring a safe and healthy environment. 

5. Prolonged Equipment Lifespan

HVAC systems represent a significant investment for facility managers and commercial property owners. 

Preventative maintenance, including replacing air filters, safeguards this equipment investment. Why? Clean filters reduce the strain on the HVAC system, minimizing the risk of overheating and other issues that can lead to system failure.

In short, a well-maintained system is less likely to require frequent servicing, reducing ongoing maintenance costs and ensuring consistent operations. 

6. Better Temperature Regulation

Effective temperature regulation is crucial for the total comfort of a facility and the smooth operation of day-to-day business

Dirty air filters can impede airflow, causing the HVAC system to struggle to maintain the desired temperature. This can result in uneven heating or cooling, with some areas of the property feeling too hot or too cold.

Consistent temperature control is particularly important in environments where specific conditions, such as server rooms, laboratories, or retail spaces, must be maintained. 

Clean air filters help the HVAC system maintain consistent temperatures and humidity levels, which is essential for tenant, customer, and employee satisfaction and overall operational efficiency.

7. Environmental Responsibility

In today’s world, environmental responsibility is a key consideration for businesses. 

Regular replacement of HVAC filters reduces energy consumption, which in turn lowers the property’s carbon footprint. At TCG, we also offer our clients the option of using environmentally friendly, recycled air filters. By implementing eco-friendly practices, facility managers can contribute to a more sustainable environment and demonstrate their commitment to corporate social responsibility.

Moreover, tenants, employees, and customers are increasingly aware of and concerned about environmental issues. A property that prioritizes energy efficiency and sustainability can attract and retain environmentally conscious tenants, enhancing the property’s marketability and reputation.
