Frost Forming

[shootace]

Hi, I have a Rudd 10 Seer unit with Heat Pump. Around 5 months ago I replaced my outdoor unit. When I turn on the heat I now notice frost building up on one of the pipes on the Air Handler (inside unit). Is this any reason for concern? If so, what should I do?

Thank you all in advance!

it almost looks like ice building on the pipe in the unit inside my house. Any ideas?

From the amount of information you have given, I can not be sure, but yeah, I do think it is cause for concern. If I were you, I'd call a local contractor and let them take a look at it.

I live in New Jersey. The outdoor unit is new, around 5 months old. It worked fine all summer. But now with the heat on the air handler inside my unit has this ice forming. Does it have anything to do with the new unit I put outside? I've never noticed this before I changed the outdoor unit.

is the unit going into heat mode. call the installer and have him look at it. may want to put it into emergency heat till he can get there . this way mo damage can be done to the outside unit since it will not run this way if wired properly

So, the air temperature outside has approached freezing, and the big pipe to your indoor unit is now frosting up?

Call the installer to look at it and make sure everything is OK (a good idea since it has switched to heating mode and things work differently in this mode.) Your previous heat pump was probably doing the same thing, but since you had not pumped a bunch of hard earned cash into it recently, you never looked at it closely. The (big) pipe needs to be insulated all the way, otherwise it drips condensation (or melting frost) over parts of your house, causing water damage or mold or something bad.

Get your system looked at, and get the problem fixed.

I would check the filter, you should change it every season. You might have a bad reversing valve. Good Luck!

What was the name brand of the old h/pump and did they change the wall thermostat? Questions ????

NO. You should change it much more often then every season. I tell my customers to check their filters on a monthly basis.

Sounds like it is still cooling.

o/b config doesn't ruud use "B" ?

I agree with you. But most homeowners wont check every month. If you get them used to seasonal changes that would be at least three per year.

like i said switch to emergency heat till he can get there
if it is wired wrong or the reversing valve is stuck and it is in cooling mode or half way between you can damage the unit. should not have ice inside. if this is a mismatch may need to be wired differant then the old unit was.

I think you're right. The insulation goes to about an inch from the unit. That inch of non insulation is where the ice is forming. Everywhere else it seems fine. I will buy some insulation and wrap it up good. Otherwise, the unit is heating just fine. It's maintaining my apartment at 75 degrees. But outside it's only about 55 degrees or so, not close to freezing yet. I change the filter every 3 months like the packaging saids. I just changed it yesterday.

The old unit was also a Ruud. The thermostat was changed also, I have a white Rogers thermostat.

I will insulate and see how it goes. I will post with an answer. Thanks all again!

Turn it to EM heat you are ruining your unit. It should not have any ice inside in the winter time.

You have a problem with your equipment.

I guess there's a reason for your screename HeatPumpJesus. What you said was exactly the problem with my unit. When we took the cover off the outdoor unit, the pipes and compressor were filled with frost/ice. Looking over the RUUD heat pump manual the installer realized that the thermostat was set to "O" and with RUUD it should be set to "B". After making this simple change, the pipes warmed up very quickly and it now seems to be working properly. Thank you all once again for your help!
