Heater keeps cutting off as if it reached the set temp.
I have not had time to vent the unit outside, but my office is big enough to direct the cold air away. Becausse of this, i don't expect the heater to reach it's set temp. once it reaches about 70 deg., the exhaust stops blowing out of the back and the fan continues from the fromt, and blows cool air. Why does this happen? is my thermostat malfunctioning? Are there adjustments i can make to keep this from happening?

It is important to set a normal temperature on the AC as a lower setting will make the outside unit to keep working so as to get to the lower temperature.So unless the temperature is reached it will not cut off.
Ideally choose a ramge of 25-27 *C for the room as the normal room temp ideal for humans is 28*C.
have you checked the filter ? do you have the temp set to low? are you trying to cool to big an area? shut it down again and let it thaw out. set the stat to mid range and trun it back on. close all unused rooms. when the unit cycles of and its still not cool enough turn the tstat down unilt it comes back on and leave it there.. unil the rom temp reaches 72-74 degree. thats the best set point .. you might be about to get it down to 70. but my bet is 1 dirty filter. and set temp to low.
If it works fine during the heat of the day, but as soon as it cools down, it freezes up, then you may have a low refrigerant charge. The other things you may check are the indoor filters to make sure they are clean, and check if you are getting good air flow through the vents. Bad air flow can mean you have a dirty evaporator coil if the filters are clean. If the above checks out ok, then you will have a low refrigerant charge and need a technician to come out and charge the unit. What happens is the low charge will cause the pressures/temps to drop inside the unit. When its hot enough outside and warm enough on the inside of the house, its enough to keep it from freezing, but as soon as the outside/inside temps drop, the refrigerant drops below the freezing point and starts to freeze. As for asking if its a problem, definitely. Hope this helps and good luck!
Hello, it is possible that the unit may be undersized for you home and not being able to keep up with the indoor heat load. The only way to determine thia have a hvac contractor do a cooling load calculation on your home. I have seen many units undersized that cause this problem.
Due to very low ambient temp, the fan will not run. Once the pressure build up, it's automatically run for some time and again cut off. But if you keep Heat mode and still tem not raised in your room means the reversable valve not working and hence the compressor and out side fan also will not work. Keep "Heat" mode and temp setting +29 to get better heat. Hope is it helpful?
you have a possible thermal overload problem in your furnace blower motor dirt will cause this problem when it doesnt allow air across the windings of the blower motor if not dirt the motors going bad and getting hot use a shop vac and eliminate dirt keep your filter changed and your evaperator a coil may also need checked for cleanliness this will require cutting into plenum my advice someone qualified and remember dirt kills
undersized is just that...you and I got taken to the cleaners.but i did put an adjustable vent in the cod air return vent duct next to the floor...it helped mine but i say some installers should.....well you know
you have either a bad thermostat or bad controls in the units unplug the furnace make sure the outside unit shuts off turn off the thermostat plug back in if it all starts with the thermostat off you will need service thanks for the high ratting keeps me helping for free.Tom
DOES THE HOUSE FEEL DRIER IF IT IS 80 OUTSIDE WITH ALOT OF HUMIDITY THE UNIT WILL RUN FOR A LONG TIME TO REMOVE THE MOISTURE(HUMIDITY) OUT OF THE HOUSE BEFORE TEMP DROPS DRAMATICALLY IS THERE WATER COMING OUT OF THE DRAIN PIPE OUTSIDE
