Reviewed information with Rohn. Install was created by another company and the first floor is 4-5 deg cooler than 2nd floor in winter. System is single zoned inverter communicating Rheem system. Recommended zoning if possible and adding a return to the first floor.
Reviewed crawlspace with Scott and recommended airsealing and insulating crawlspace with closed cell foam. Also, recommend duct sealing as there are areas with obvious leaks on the return side. Scott mentioned his bills were more than last year. Barry set lockout on heat pump to 60 degf to run gas furnace sooner.
