If your heat pump is blowing out cold air while the heat is on, it could be caused by a few different issues. Some common causes include:
Low refrigerant levels: If the refrigerant levels in your heat pump are low, it can cause the system to blow out cold air. This can be due to leaks in the system or other issues.
Dirty air filter: A dirty air filter can restrict airflow to the system, causing it to blow out cold air.
Faulty thermostat: A malfunctioning thermostat can cause the heat pump to blow out cold air instead of heat.
Faulty reversing valve: The reversing valve is responsible for switching the flow of refrigerant between heating and cooling mode, if this valve is faulty, the heat pump could blow out cold air when the heat is on.
Defective fan motor: If the fan motor is not working properly, it may not be able to circulate warm air through the ducts.
It's best to consult a HVAC professional to diagnose and fix the issue. if i was able to help my cashapp $ralphpapi thank you have a blessing day
First, make sure you are not low on antifreeze and that the heater is set correctly. Also, it is winter, make sure your coolant is not frozen. Heaters take longer to work in the winter when it is cold outside.
If the simple things are all ok, you may have a problem that will require diagnosis and new parts to repair. I recommend a pro shop with certified mechanics that will do the job right quickly the first time.
When any unit 1st come's on, you'll always have some cold air that's in the ducts that will blow out before you get warm air. If your duct work is uninsulated in a cold basement or crawl space then it will be even more noticeable. When the unit is heating from the Heat Pump mode, it takes a little longer for the gases to get warm enough so you'll fell heat. When it gets cold enough for the unit to switch from heat pump to the gas or electric heat source, you'll get warm air faster. If you have gas heat, some Thermostats have an anticipator setting for the gas valve. If it's set wrong it will effect the on/off cycle of the gas valve.
All duct work in non heated and a/c spaces, including inside walls,above dropped ceilings, in attics and crawl spaces, must be sealed & taped at the seams and joints and then insulated and taped.
Most new construction has solved that problem with insulated duct board, flexible insulated supply's and special tape.
I have a lux electric thermostat my furnace will blow out heat for about one hour to maybe three then it will start blowing cooler air,I then cut it off for thirty seconds or longer once I do that it will start blowing out heat again then it will repeat it self again what could be the problem.
