Your furnace filter might be in BACKWARDS right now 😬
Walked a basement today and found two things worth sharing:
1️⃣ Multiple slow leaks on this old drain line — see all that corrosion and buildup? That's years of drips. It never stays slow. That's a stained ceiling waiting to happen.
2️⃣ The filter arrow pointing the WRONG way. A filter only works if air flows through it in the right direction. Backwards = choked airflow, higher bills, and a system working way harder than it should.
Do this today 👉 pull your filter and make sure the arrow points WITH the airflow (toward the blower). 30-second check.
