I think you have a problem with your A/C unit. You may want to have it checked out.

2. By the way, did you say it is a heat pump?

If so, which kind, air cooled, or water source?

4. Do you have a unit outdoors with an air coil?

Or is everything contained inside?

6. OK, then your heat pump is air cooled

Which means you have refrigerant lies between your indoor and outdoor units.

My suspicion is that you have a refrigerant leak since the performance suffers both in the heating and cooling modes. That is my best guess. But then, your outdoor coil could also be dirty. You said earlier that your electric bill is high which is another symptom of an undercharged unit.

7. Thanks

I'll have it checked. Should I do this in the winter, or wait til it's a bit warmer?

8. A competant mechanic should be able to charge it in any season

Don't let anybody add refrigerant unless he looks for and fixes the leak if it is indeed short of refrigerant.

I would attribute the problem to an undersized unit but the summer symptoms indicate another problem. While he is there, ask him to tell you how many KWs of electric strip heat you have. Ask him what size wire is run to the indoor unit in case more heat strips can be added to your emergency heat. Ideally, you should be able to lock out the heat pump and heat your house with electric heat if your heat pump fails.

Let me know what happens.
