Thanks for your question,
Just a couple of questions first, is your ducting insulated ? is there a fresh air intake on your system ? if either of these is the case, the first would be that you need to have your duct insulated, it is good practice to have them insulated as it will save you money down the road as to not have as much heat loss or cold air from the duct escaping into the home, second if you have a fresh air intake, alot of times that is where fresh outside air would be coming in from, there should be a damper on the venting, if there isn't I would suggest having one installed, normally it is installed on the return side of your ducting. Hope that was helpful, please leave some feed back as to how we did, thanks again,

Indoor fan blowing cold air when on heating


The indoor fan will continue to run. When heat pump goes into defrost the outdoor fan stops, the reversing valve switches and the unit is basically working in the cooling mode. In order for you not to feel a blast of cold air in the winter the electric strip heat also comes on so the indoor fan must run while the strip heaters are on.

central air or window unit? central systems use a low/high pressure limit switches which self reset when pressures are nominal. suction about 50-60, high pressures around 300.
