Had Reliable install my Goodman high efficiency furnace back in 2014. Today was the 2nd time it has broken down since installation, the last time being January 2018. I tried contacting them through 3 different methods - general phone # (left two messages - no reply), direct email to the owner (no reply), phone message to the owner's personal direct # (no reply). I had to call another company to do the repair. Found out: #1. The furnace was INCORRECTLY installed! The piping to go outside is both running too far and does not vent properly in a slightly downward direction for drainage, it tilts upwards so it isn't draining properly and the unit is now getting water inside!!! #2. We were sold the WRONG furnace for a house our size! The furnace we were sold, a GMVC950704CX, is for a house with square footage over 2,000 square feet. Our bungalow is only 900 square feet. #3 Has it locked into running in the first stage so it doesn't go to the second stage because a furnace this size wouldn't work properly at 2nd stage for a house our size. Which means it is NOT running properly as a high efficiency furnace or safely (the improper installation)!!! I am appalled and disappointed that I will probably have to purchase an entire new furnace after less than 5 years!. AVOID this company. I'm in shock that I ever thought this company was good.
