I have an oil furnace. There's a slight smoky smell in the house. I checked downstairs for leaks around the flue and don't see any. The furnace also seems to be cycling on and off too often. So I conclude that the most likely cause of both problems is a dirty filter. When was the last time I had the furnace cleaned? I don't dare answer that.

It can take quite a while to get an appointment for a cleaning. In the meantime, can I change the filter myself? Anything I need to know about doing this? Does Home Depot sell filters? Or can I vacuum the filter?

I read online that you're supposed to change the filter every 3 months. That seems excessive to me, but I conclude that every 3 years is bad. Very bad. I have a carbon monoxide detector (recently replaced). I will call the oil company tomorrow if they're open.
