Question about Heating & Cooling
My heat pump keeps freezing up in heat mode. The freezing is occurring inside the house on what I think is the coil. The copper lines that connect to unit ice over as well. I noticed a P-trap like drain system , Im not experienced with heat pumps but I know a ptrap isnt a good idea on low flow drain. Havent tested system yet after removing drain line. Any ideas as to why it would freeze its 35 degrees F out at the moment

Operate your air conditioner with the fan in the on position. But first turn the fan on, turn the temp up or shut the cooling off. Your coil is more than likely frozen over. At night when outside temperature drops the refrigerant pressure and temperature in the system also drops. This action can cause icing of the cooling coil, with the fan in automatic everything shuts down at the end of a cooling cycle. Thus no air movement to melt ice on previous cooling cycle.

Check your filter in the furnace, Then check the coil to make sure it is clean. If neither of these two solutions fix your problem you may be low on refrigerant.

if one or few pipe may not aproblem may be the thermostat is aet to very low cool anf the fan on low speed or the thermostat is defective also if this icing is growing up means
-1 evaporator need cleaning
- 2 a smll freon leakage

This sounds like you are low of refrigerant. Or you evaporator needs cleaning. Have it check out to see if you have a leak in the system

The most common reason for freezing up is 'air flow,' and since you've already changed your filter - have you checked out the coil (the one that cold air comes from) to see if it's clean? If the filter you changed was really 'bad dirty' then it's a good bet the coil could be dirty also - thus restricting the air flow.
If you're satisfied that the coil is clean - about the only other thing it could be - is 'low on refrigerant,' which of course will take a Service Tech to find the leak, repair it and then re-charge the unit with refrigerant.
One other thing you might think about - are you running the blower motor on 'low speed?' If you are then put it on 'high' and see what happens.
Again, the most likely cause of your problem is air flow or 'low load,' - so I would really look hard for an air flow problem of some sort.
hope this has helped a little

Testimonial: "I had replaced the filter on this unit with one recomended by the local hardware store and the model of my unit was on the box but the new filter was to restictive of air flow - I called the service tech who installed the unit and he immediately noted the filter that I had purchased and replaced it with a filter that he normally installs and since he put the new filter in, it works perfectly. The filter I used looked like a paper type filter and the one he used had more of a fiberglass appearance. Needless to say - his filter was the answer."
