I had a Goodman duel fuel installed,GMS9090 gas furnace and CPLT36 heatpump.My question ,is it ok to have blower connected at same speed(Med low) for gas and heatpump? Will this unit have enough cfm at this speed for cooling? Contractor first had heat on low and heatpump on med,but wife though house felt to drafty! We like it better this way but I lost app. 5 degree at the register on heat pump mode. I was getting 91 degree at 40 degrees outside and now the very best is 85.5. Thanks very must for your comments.
