Heater-Furnace Tuneup

[Grumpy Grampa]

Hi. I have a 2017 Miramar 37.1. Has anyone ever performed a tune up on the heater-furnace, and is it necessary?

Thanks

Grumpy,
I occasionally take a leaf blower and dust out the ducts and heater box.
Look for loose wires, look at board for spider webs, etc.
If it works dont fix it.

Good info.

Thanks

I'm with pillbox. I take the shop vac and suck out the vents when I change the smoke detector battery. I also check the screen on the outside of the heater to make sure it is in place and no mud daubers have started building a nest.
