Our house is going to be 17 this Sept. & they installed Goodman gas furnaces & A/C units in all the homes. My HVAC guy said Goodman private labels for other popular brands, and under their own name. They are a major manufacturer of the units. Our furnace is a high-efficiency & I have had 3 problems with it: at about a year old, the igniter rod broke, so my installer replaced it & never another problem. Then at about 10 years, the impeller bearings went out. I replaced the unit - EASY fix & under $100.00 for the part. Most recently (this winter), the collector box began leaking water. Once again, the part was under $100.00 & very easy to replace.

As far as the A/C unit, the capacitor went out last summer. Part was $30.00 & about 20 minutes to install - back in business.
