Question about Heating & Cooling
Posted by Anonymous on
THERE is not a whole lott left not quite sure what all you have had done by post but i will let you know that the unit will run on a timed period based on outdoor defrost control board and once that time elapses and unit is still runnning it will check the defrost thermostat on the coils if the coils are cold enough (ie: frosted) the thermostat will send a signal back to board to go into defrost. the reversing valve actually switches back over to a air conditioner while mean while your indoor supplemental heat comes on rather it be electric or gas if they have it wired right. so that being said you could have a bad defrost control board if they have already replaced the thermostat outside. also if unit is low on refrigerant will freeze up ...lastly i want to point out not sure what your location is but when it gets down to 30 degree temps the heatpump will frost up it shouldn't be a block of ice but will frost up and look like snow on in completely normal. i tell people here in texas with heat pumps anything below 35 to go ahead and run the emergency heat just so you have warmer air and a stable home temp... yes it does use more electricity initialy ,but if you can warm a house in 2 hours with e-heat and it takes the heat pump most of the day running what is really costing you more? hope this helps and good luck to you please vote
