This is my second Goodman furnace and it hasn’t failed me. What’s important for readers of review sites like this to remember is that, people offering low ratings of furnaces aren’t mentioning that 80% of furnace breakdowns happen due to lack of maintenance on the part of the homeowner. Given that you use your furnace more than you use your car, it makes sense to get your furnace serviced annually. Alas, people never forget to get their car tuned up but they never tune up their furnaces on a regular basis and they don’t live in their cars, they live in their houses. Finally, ALL FURNACES ARE THE SAME. If you take the front panel of any brand of furnace, what you will see is a multitude of parts that are made by third party manufacturers like Honeywell, for example. There are no 100% Lennox, Trane, Carrier, Bryant furnaces just like there are no 100% Goodman, Amana, Payne, or Rheem furnaces. They are just boxes that are assembled at a plant in the US. At the end of the day, the most important thing to remember is that furnaces are designed to work. What generally causes problems is the contractor that the homeowner has hired to install the equipment. If you go cheap, you’re going to get a cheap installation where they cut corners and where the furnace is doomed from the date of installation.
