Today I arrived on a service call thermostat wasn’t functioning at all. It was blank I fixed thermostat fixed lose wire. I also did a 2 system ac maintenance with club members renewal of membership. I found on basement unit no Armor flex for instillation causing the unit to lose temp because it’s not insulated. I also did noticed basement unit needs to have blower wheel cleaned. Everything else checked out ok out to manufacture specifications. Office needs to give club members a call for appointment for blower wheel cleaning.
