I have a 1 year old goodman 1.5 ton heat pump. I am going to call somebody before i turn it to cooling but this morning it was 60 outside and the room was 60 and the unit was running puting out cold air (set point was 70).The pressures on the unit were 100 psi on high and 90 on low. What might be the problem. I am not a tec but just interested.
