How often should I change my air filter in Mercedes to prevent dust buildup?

In Mercedes, where dust buildup is common, we recommend checking your air filter every month and replacing it every 1-3 months, depending on usage and household factors like pets or allergies. Regular changes prevent clogs, improve airflow, and protect your HVAC system from strain.

What are the signs of duct leakage in my home, and how can Fern's AC help?

Signs of duct leakage in Mercedes homes include uneven heating or cooling, higher energy bills, and excessive dust. At Fern's AC, we perform detailed duct inspections using specialized tools to locate leaks, then seal them with professional-grade materials to restore efficiency and comfort.
