You may be surprised to learn that I have intentionally kept my old furnace. I easily care about my old oil furnace, I think that all the people would have had it changed out for a modern 1 by now although I see no need to swap it out for a modern 1. If it isn’tbroken why would I need to maintenance it? You would be surprised how several people entirely get on to myself and others about keeping an old furnace. Truly, I’m not sure why it matters to them so much although I intend to keep it for as long as I can. My oil furnace have maintenance myself and others well for over 20 years & as long as it continues to do so I will continue to keep it. My family keeps snagging myself and others about it saying that I need to get a modern 1 because eventually it’s going to cut down although I tell him that I have had it officially worked on in maintenance by the heating & AC specialist & the last time I had the Heating & A/C woman out here I asked him if I would need to worry about replacing anytime soon & she told myself and others that I would not have to worry about replacing it for a long time because despite her age it was still an excellent condition. So I easily do not have anything to worry about. I think the issue is is that my family are all about having the best of the best modern appliances, & this is no weird with Heating & A/C products so when they see myself and others having something from a weird era I think it weirds them out. They can think what they care about however for myself and others my furnace is perfect.
