Backstory: Our furnace is old. Like 20+ years old. We bought our townhome in June. We have a 1 year warranty, but to get them to check anything, it'll cost $100.
When the furnace hasn't been on for a few hours, it takes a while to start up. Clicks at least 10 times, but then starts up. It doesn't seem to have this issue if it was on beforehand.
I have never made any repairs to a furnace before.
So my questions -
1 - Is it worth it to have them come out and check this? (cost wise, assuming they find it, they would cover repairs)
2 - Is this a quick/easy fix for me to do? It seems like it could be something with the spark or a sensor. I'm not sure how to go about testing this kind of thing to make sure I'm fixing the right part.
3 - Is it worth fixing this instead of just replacing, which we can probably do over the summer?
I don't think there's any danger in this, and we just about have enough set up to replace the unit (it's one of 3 ancient utility units in our house, the HVAC and water heater are also original).
