Need a Coil for Air Handler

Can you see the condition of the coil itself? If it is blocked this could be a cause for the frozen coils. Also, check the condition of the blades on the indoor fan. Dirt and dust accumulation on the blades reduces airflow.

Ruud UBHC-SERIES is a HEAT PUMP AIR HANDLER
AND FAN COIL UNIT

Compressor and condenser not included

What's wrong with your current AHU? Any Ruud dealer can assist you. Most 4 ton units work with r-22 or 410a. As a side note, most parts in an air handler can be replaced unless the case is rusted thru.

Hello
Your still froze up.There is a freeze cutoff device in the air handler upstairs.
Look for a thin silver color tube near the coil and follow it to the control box,there may be a reset button.If not, try using a hair dryer to warm up the coil and it should reset itsself.
These freeze devices can take an hour to reset on there own sometimes,do not run the compressor while doing this.

Hi, yes the number you are showing me 036 indicates its a 3 ton unit. For every ton of cooling, you will have 12,000 btu's of cooling. 36 divided by 12=3 ton unit. Its showing me also its a Ruud Handler 2.0 ton which would be a Model# UACC-024JAS? If your mobel number is the one you gave me, UACC-036JAS, this is a 3 ton unit, absolutely no questions. I hope I have been of help to you. I am a licensed air conditioning / Refrigeration /Heating Contractor. Let me know if I have been of help.
Sincerely,

PS If this is a split system with the indoor air handler and condenser outdoors, both coils must be the same tonnage for it to work for you properly. You can't have a 2 ton indoor evaporator coil with a 3 ton condensing unit.

It is a 3.5 ton air handler and without knowing for sure about Rudd only making those sizes which they should, they more than likely would have gone up to a 4ton coil. One way to cross check this, is to see what ton the condenser outside says it is. If you have a 4ton condenser, then you should have a 3.5 to 4 ton coil, either being okay. What you don't want, is a 3 ton coil and a 4 ton condenser and so on. A half ton isn't going to be a problem regardless, but if anything, you can always take the measurements of the coil if you are trying to replace it.

This may be a bigger issue than you want to tackle alone, generally speaking the coil will have to be ordered from a dealer, as most wholesalers will not sell to the general public. Further, this will require brazing the new coil in, evacuating the system, installing a dryer and recharging.

follow the copper lines coming into the air handler.1 will be large and insulated and the other smaller and uninsulated.They attach to your evap coil.

I do have a technical .PDF document for this model. It is not the users manual. It shows the matching coil, Air flow requirements, and other technical data. If this is what you want please provide your email ( I don't know of any other way to send it to you on this web site) address and I will send it to you. Thanks.

Open the access panel on the air handler in the attic and take a look at the evaporator coil. If you have no airflow, and you just changed the air filter, then you probably have a buildup of airborne crud on the coil that's blocking airflow. If you do have a layer of buildup blocking airflow through the coil in the air handler, just take a $5 fin comb and scrape all the crud off the coil fins. This can make a dramatic difference. Hope this helps! ;)
