It takes a few minutes of run time for the compressor to warm up the discharge gas, which is the heat source.
A heat pump is designed to extract heat from the outside air, even during cold weather. It uses this extracted heat to warm the indoor air. This is why a heat pump blows warm air instead of cold air during operation.
I would change the thermostat first. If that dont work change water pump
check the heater core
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!
For sure i do
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.
A heat pump operates efficiently below freezing temperatures by using a backup heating system, such as electric resistance heating, to provide additional heat when the outside air is too cold for the heat pump to extract enough heat. This allows the heat pump to continue operating efficiently and effectively in cold weather.
A heat pump may struggle to keep up with cold weather because it becomes less efficient as the temperature drops. Heat pumps work by transferring heat from the outside air into your home, but when it's very cold outside, there is less heat available to transfer. This can make it harder for the heat pump to maintain a comfortable temperature indoors.
The heat pump auxiliary heat may be always on if the temperature outside is very cold and the heat pump alone cannot efficiently heat the home. The auxiliary heat helps provide additional warmth when needed.
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.
