Originally I had planned on getting the furnace replaced last summer and when I asked for advice here, Goodman was the most recommended. One of the reasons was that a "do-it-yourselfer" such as me would be able to repair it. I inspected the unit and doubt if anything should present a problem. The parts are guaranteed for ten years and since I'd replace them myself don't think it's going to cost me a fortune to maintain.
In the 35 years I've been in my house I've done 100% of the appliance repairs myself. Compared to the industrial equipment I worked on for my job, home appliances are not a big deal.
As to the old "they don't make them like they used to" adage.
Yep, my old oil-burning furnace definitely had better sheet metal than the one I just had put in. OTOH: If that oil burned could go six weeks without breaking down or needing some type of maintenance, I was lucky.
BTW: I will get a fairly decent rebate from "Focus on Energy"
It looks like anyone who gets a high-efficiency furnace qualifies for a $150 rebate, but since I'm retired my income will qualify me for a higher rebate. Will have to submit the paperwork to know the amount...but it's up to $850
