It takes a few minutes of run time for the compressor to warm up the discharge gas, which is the heat source.
if it's the outside unit, it will always be hot air. that's the air being pulled out of the house. cold air in, hot air out.
I would change the thermostat first. If that dont work change water pump
check the heater core
For sure i do
Do you have a heat pump or Gas Furnace? With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!
In a Cold Climate and Hot Climate: Each ton of heat pump capacity can heat/cool approximately 500-600 square feet.In a Moderate Climate: Each ton of heat pump capacity can heat/cool 600-700 square feet.So either a 5.0 ton heat pump in a cold climateor a 4.5 ton heat pump in a moderate climate.
no sounds like your wires are crossed at your thromsthat Answer If you have a heat pump system, YES the compressor should run. You can find out if the system is a heat pump usually by looking at the thermostat. Heat pump thermostats usually have "Cool-Off-Heat-Emergency Heat" on the system switch. Another way would be to feel the air coming out of the outside unit when the heat is on. If the air coming out feels very cold, then it's a heat pump. even if you have a heat pump, the only way the in door unit should be producing heat is if you are all electric if you are gas the heat pump should lockout to prevent the persure from getting to high causing the indoor coil to blow up.
Low coolant? Bad thermostat? Heater core plugged, restricted or airbound? Bad heater control? Water pump not circulating coolant?
Probably not but it can switch from heat to ac if this answers your question First responder is correct, if you have a system know as a heat pump. If you have separate heat and A/C , having you A/C turned to extreme cool may cause your heat to come on. A window unit blowing hot and cold simultaneously is indicative of the A/C motor overheating, and could be dangerous.
Refrigerant
That is exactly how a heat pump works in heating mode are you sure it's not a heat pump?
If the unit is a heat pump, and the fan switch is set to ON, the unit compressor will cycle to maintain room temperature. Thus, it would blow hot or cold, depending on if the compressor was on, and the thermostat was calling for heat. Turn the fan switch to off, and let the thermostat bring the fan on. Not working part, no comment on that.
