I'm trying to figure out if I'm going to need a new furnace soon.

If you're noticing that your heating bills are increasing, it might be time for a new furnace. You can check the age of your current furnace by looking at the model number or reading the sticker on the unit. If it's over 10 years old, it may be time to replace it. Additionally, you can get an estimate of how much your furnace will cost to repair or replace by researching online and comparing prices.
