    The heat pump unit freezes entirely on the inside and then begins freezing on the outside. We have had two relay switches replaced, which worked for a couple of weeks, then the problem reoccurs. When the icing occurs, the heat pump sounds like a locomotive running.

Icing up on the outside unit of a heatpump is normal in cold weather. your heatpump should go into a defrost cycle on a regular basis when its that cold.

as far as not good heat goes, when it gets colder outside there is less heat in the air for the heatpump to pickup and put off inside your house. on a 40 degree day the air temp will probably be only around 100 dgrees coming out of a vent. compared to a gas or oil furnace that puts out about 130-150 degree air it feels very cool.

hope that helps..

In freezing weather the heat pump efficiency drops. The freezing is normal. The equipment has a board and sensor to defrost your heat pump. Now this system can fail but freezing rain and snow get pulled into the unit get pulled into the unit coil and freeze blocking airflow. You can defrost the unit by turning it to cooling. This is what the defrost board does automatically.

Pool spa heater when freezing temp


It normally will heat up with pump moving water, once the threshold is achieved - system will come out of its Freeze protection mode and will begin to work as programmed. If there is a heat call, heater will come on.
You can also locate the sensors, both the Water & Air (they need to be very close in temperature for this to work) then place them in water warmer than the actual ambient temp, & above the temp that triggers "Freeze".

My unit has been running all day. set on 75 degrees and still only 65 in the house


If this is a heat pump depending on the outside temp. it may not bring the temp. up. It is really not efficent to run a heat pump below freezing or near freezing.I suggest running the Auxillary electric heat if. Most heat pumps have auxilarry back up electric heat banks installed in them.

HEAT PUMP OPERATION FOR TEMPSTAR SMART COMFORT 2400, MODEL THC436AKC1. LOWEST OUTSIDE TEMPERATURE FOR OPERATION?


I have installed many heat pumps and if it is installed without and ouside temperature sensor I would not recommend running it below freezing 32 degrees farenheheit. Running a heat pump at low outside ambient temps. can hurt your compressor and that is the most expensive part of the outside unit.

Really not efficent to run a heat pump at those temperatures. Below freezing is not good for the compressor in the outside unit. The humidity in the house with the low temp. is causing the condensation on the windows to freeze. Kinda like an air conditoner does in the summer without the freezing humid air from the house goes over the cold a/c coil and the moisture condensates on the coil running down to drain pan. raising the temp. in the house and lowering the humidity should help. I would also recommend running the electric heat in low outside teperatures.

Water leaking


depends on where its leaking. Air conditioners create condinsation it is a by product of it function. the water should drain thru a drain line and either go into a floor drain a pump or outside. if its leaking all over your floor it may be a clogged drain. If its not working well too then it may be freezing up and causing excessive condinsation beyond the drain area. you should make sure your filter(s) are clean and the drain is clear.

18 year old Janitrol Heat Pump freezing up.


i would get someone to check your refrigerant levels have you ever had the evaporator coil flushed and cleaned? proper refrigerant levels and proper airflow across coils are extremley important not to scare you but 18 yrs is a long time on a heat pump 9-12 years is the point where they really loose there efficiency going for a newer one would probably cut your operating cost in half if not more depending where you live there are a lot of people not familiar with heat pumps so i suggest finding a company that specializes in them to service your unit

Condenser frost's up on my heat pump


On a heat pump the system reverses during the heat cycle to bring in outside heat that will cause the outside coils to ice up. There is a defrost timer or pc board to send the unit into defrost every so often. This is a common problem with heat pumps or possibly low or refrigerant. Heat pumps will freeze up at low outside temps, but unless your in the Artic right now that shouldn't be a problem.

Freezer stops and start


ice cream is always the last to freeze and a temp of minus -10 degrees is usually required to get it to get hard. if you put the ice cream in the door it will be especially tough to freeze. a good thermometor is a good investment as you can observe the temps. usually ten degrees or 20 degrees is what they run. yes they do cycle on and off as long as they hold temps thats good. the outside of the freezer gets warm because the hot compressed refrigerant is spread through piping near its surface giving up its heat of compression . setting the stat to max will freeze the ice cream eventually but utility bill suffers . good luck
