Any heating and cooling Guys out there? I have a question

Once you get the problem resolved, you may want to do an over all tune up on it.

I just went through the system in my house that has butchered vent ducting, but I managed to get the system to cycle in a reasonable frequency for my house and temp climate.

Adjusting things like the thermostat's anticipator, keeping a clean filter and clean furnace inside and out will help extend the lifespan of the heat exchanger, the ignitor and cut down on your utility bill.

Each safety switch is there for a reason. Some of them are adjustable and should only be set once, like the heat exchanger max temp switch. The anticipator on the thermostat, when adjusted properly on a clean system with working components, is probably the most important thing you can do to a system to extend its life, along with keeping a clean filter in it, so the heat exchanger can cycle properly without overheating quickly and without cycling too frequently.
