Be aware Gibson is an old appliance brand whose name only is used in Nordyne's umbrella appliance HVAC brands. Not very familiar with them. I personally would stay clear but others have had success. Usually considered a second tier brand under a dealer's main brand.

I would suggest looking at Rudd/Rheem HVAC. Not always cutting edge but solid equipment that is underrated and overlooked in the residential HVAC market.

Perhaps others can offer their opinions.

IMO
