Clean Air Filters: The Secret to Cheaper Energy Bills #shorts

Short, two-speaker YouTube clip (by Derek Cole) arguing that clogged/dirty air filters—"dirt"—are the primary cause of reduced HVAC efficiency and higher utility bills. The speakers claim dirt can raise utility bills by roughly 10–20% and lead to prematurely accelerated, costly replacements (examples: multi-thousand-dollar, up to $10,000 jobs) that could have been avoided by changing a low-cost (~$15) filter. The video cites experts Eric Cole and Derek Cole and references Energy Star guidance stating that changing your air filter is the single most effective thing a homeowner can do.
