I purchased an American Standard furnace from Hogg in November of 2017. Within 6 weeks, we needed to change the main board. A couple of weeks later we needed to replace piping that cracked between the furnace and venting. On top of that we needed to install a new return vent. I think Scott was so eager to sell me a furnace that he presumed the existing duct work could handle the new furnace. I recall asking him whether existing ductwork was sufficient and he said that he had no concerns. The only silver lining was that the service in response to all the hassle was very good.
