Goodman Heat Pump freezing up

I have a new 31/2 ton Heat pump, it freezes up at night when the temp is under 30deg. I was wondering what should the defrost timer be on 30 60 or 90. I am trying to find the right setting so it won't over defrost, if that is possible. and during defrost cycle I've noticed the outside fan continues to run, is this normal? I don't know what the timer is set on now ( Factory Settings). The installer says the freezing is normal. Everything else seems to be working, my bills are higher than the old unit that was over 25 yrs old. Can anyone help with some advise. Ice cube in Tennessee

In your climate usually the defrost timer would be on 90. However if you are in an upper elevation and it gets colder then set it at 60. what model unit do you have? Did they change both indoor and outdoor units? I would have to know the model # to tell if the fan should run in defrost. In most cases I would say no.

Sounds like it is not going into defrost if the fan runs during defrost.

Ice/frost buildup can occur, but if the unit becomes a solid mass of ice, then there is a problem in the defrost circuit. Could be the defrost sensor as well, which is a little round metal can with 2 wires in it attached to the refrigerant tube inside of the condenser. But your serviceman is right, some frost is normal.

Defrost time setting is somewhat subject to where you live.

On all the units i worked with out a defrost system if it frosted up it was because its running to long and may be was too small for the area tiring to cool.it could also be low on charge and so can't cool efficiently.that may be possible if its a new system. ive had customers that had gotten a new system from a HVAC company and it didn't do the job and they told the company to come and get it and put the old one back.and they did.whats the use of a new if it cost you more money to run.i think your HVAC company dosen't know whats going on.you may want another opinion

Goodman gph1348m41ac unit is blowing cool air in heat mode with mid 30s ambient outdoor temp. I turn it off then on and will usually blow warm air but this cycle is becoming more repetitive. any expert...


A heat pump on the optimal heating day (about 50 degrees ambient) will only deliver approximately 85 degree air as compared to 125 degree air from a fossil fueled furnace. The colder the outdoor air is the less heat there is available to be transferred to the living space. At 30 degrees, the heat transfer capability is getting close to negligible meaning the run cycles will be approaching continuous and eventually as the heat pump along cannot maintain setpoint, the outdoor stat or stats will bring on auxilliary heat in the air handler.

If your ambient temp is below the 'balance point' of the heat pump, the house temp will drop a little lower and most times energize the heat strips through the outdoor t-stat. Your outdoor stat could be set too low for the heat pump to carry the structure all the way down to the balance point so when you turn it off and back on, the lower indoor temp automatically brings on the heat pump plus a heat strip or two, thus the warmer air. Second stage on the stat satisfies due to the heat strip, drops them out of the circuit and the heat pump is left running on first stage heat delivering the perceived cold air.

Your outdoor stat could also be not functioning correctly and not allowing the heaters to come on until the system is turned back on reestablishing the two stage call for heat.

I have noticed my heat pump is freezing up on the outside unit, we have had freezing rain and snow the last 2 days but I have never noticed ice accumulation on the outside of the unit, it also seems like...


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.

My 4 ton goodman heat pump goes into defrost and than after the cycle return in cooling stage at least the indoor coil starts freezing is the expansion valve working corectly


The reason for indoor coil freezing due to coil dust blocked-(Clean coil). 2. Less rpm of indoor f.motor. (Replace capacitor). 3. Short of gas. (Find leak and repair and then recharge gas.)

I have 4 ton carrier heat pump / puron. It is a new system been installed about 3 months. Live near Dallas Texas and lately the temp has dropped into the low 40's at night. The heat seems too be working...


The water is from humidity in the outdoor air which has condensed and then frozen to your heat pump outdoor coil. The heat pump will defrost occassionally, depending on how much frost has accumulated to the coil and will then generally drip off the unit and onto the ground. This is normal. To keep the water off the drive way may mean having to move the heat pump to a place where the condensation can run away from the drive area. Or provide some other means of redirecting the water.

Do you know how I can get a Goodman Ht pmp Manual


this manual willl not help your system perform better , have a qualified tech check your sub-cooling. temp diff, and match your piston with your coil. many goodman systems may say they are 3 or 4 ton but are half a ton smaller than advertised at the compressor. a three ton system will have a two and a half ton compressor

Better off taking good money and put into something with a warranty. its probably a 4 hour job to recover solder in new valve change drier pull vacuum recharge If your system is freezing up it may not be the valve could be a check valve. low freon dirty unit all would cause the unit to freeze up is the company competent in working on heat pumps don't get some body that can work on you want in FIXED . from what you said in your 2nd post i am not convinced its the valve. Tom p.s i am in the mid west prices are not too far out of line.

Goodman PHJK048 Heat Pump Package


ok...where to start.lol ....the thermostat is just a switch.It will tell the unit to run or not run.if you measure the temp with the heatpump running,the air is warmer than 68 but it feels cool to you because your body is 98.6.The unit will run more often and for longer periods when the temperature drops outside for a few reasons.First,your house has more of a load to heat,meaning you have more heat loss because of the difference in temperatures outside and inside.Second,your heat pump pulls heat from the outside air.The colder the air outside,the less btu's for it to pull.If you have anymore questions hillbuck29@aol.com Hope this helps,Dave
