This is a heat pump so the problem could be anything related to the compressor, refrigerant circuit, etc. or the defrost control. There is usually a switch or screwdriver slot switch on the front of the unit when you take the large cover off. This will force the auxilliary heat on regardless of outdoor air temp, thus bypassing the compressor heat pump system (and costing you more to operate it.)

SOURCE: my heat pump blows cold air for the first 10 minutes or so

Don't know how long you have had a heat pump but thats the nature of them in colder weather. Some people prefer to switch to "emergency heat" on the t-stat when temps fall below 20 or 25 degrees. This bypasses the heat pump and allows your back-up heat to heat the house. If your house is total electric your emergency heat is an electric furnace and it should handle the load if it was sized properly. Don't leave it on emergency when it warms up because your heat pump is much cheaper to operate than the furnace. As always, check your air filter since it can restrict the amount of air that moves thru the furnace, which is critical. Hope this helps

SOURCE: Heater blowing out cold air

Yes you could have a bad overload on the heater element which is fairly simple to fix. To test for this pull the heater out and get an ohmeter set it to continuity and check the continuity first through the entire heater element then if there is none pin point the overloads and check to see which one has no continuity.

SOURCE: unit not blowing cold air

you have a slow leak in your refrigerant and need to find the leak. you will have to get an AC repairman to come to your house and check it for leaks and fix the problem.

Heater blowing out cold air

Several things.
If the heater hoses are hot, the problem could be a blend door under the dash. The blend doors direct air thru the heater core and out the vents.

Ac blows hot air ac compressor is ice cold but the vents blow hot air when enige is hot. bloows cold air when engine is cold

check your air diverter doors, sounds like the door for heat is open, when a/c is selected the doors should move and close the heater off. the heater will over power the a/c. the door controller is located on the environmental station under the dash neat to the floor. the control is electronic and probably not functioning
