Able to do my own oil furnace work

I have gotten genuinely fantastic at servicing my gas fireplace, however i have owned my oil furnace for over several years.

It is slowly dying on me… Technically it should be totally done in many years. I am planning to extend its lifespan. I genuinely should call an Heating, Ventilation as well as A/C business and have a worker perform heating service yearly. I suppose the guy will try to sell myself and others oil furnace repairs that I don’t need or a singles that I can do. I also suppose I can do all the heating service stuff that he does. I have l gained my heating machine. I suppose I need to turn the oil furnace off for days before I operate on it. The metal parts and front glass plate get hot and stay that way. I l gained how to take it completely apart and what tools access the oil furnace easiest. I have fixed a wide range of troubles before! My wireless control component control was not working. I changed the battery and then realized the issue is with the heater. My fireplace also decided for a while that it was not going to turn on when I wanted it. I l gained how to manually start and reset it. I then got it all cleaned up and the fireplace became more willing to turn on, but for a while I was residing with a horrible grinding sound. I deduced there was too much debris on my fan. I then inspected that. I have saved so much money doing my own heating service. A little googling and patience genuinely does go a long way.
