Do I have a story to tell you—another lesson I’ve learned the hard way so you won’t have to. Truth be told, if my faux pas helps you avoid a huge expense, I’m happy to have suffered it.
While researching to help a reader solve the mystery of black grimy lines around the edges of his home’s carpet, I casually asked my husband if he’d replaced the filter in our heating ventilation air-conditioning (HVAC) system recently. I got one of those blank stares I could easily translate: Nope, didn’t even think about it.
When we bought this house, we had the HVAC system inspected, serviced and the filter replaced. Then we got busy with leasing it while we planned and executed our big move a year later. HVAC filter? Completely forgot about it. By the time I brought up the subject, it had been more than 2.5 years!
The scariest thing ever was to open that door on the HVAC system, dutifully labeled “Filter.” I cannot adequately describe it but I can tell you that it was nearly black and covered in what looked like fur. So gross. I’m surprised the entire system didn’t just blow up out of sheer rebellion for lack of attention.
I have since learned about the true cost of a dirty HVAC (heating, ventilation, air-conditioning) filter and it’s not pretty!
