So guess who forgot to replace the furnace filter last month? I was wondering why the furnace was running constantly for nearly 2 days trying to keep up with the below -30°C temps outside.
The last two places I'd been living I never had to worry about it. The first was the basement suite I lived in during university and it was handed by the tenants renting upstairs.
The second was a townhouse that had this old electronic one from Sears that stopped working long before I moved in.
