I NEED TO KNOW WHAT SIZE (TONNAGE) A MODEL UBHC-17J11NFD IS. THIS IS A RUDD AIRHANDLER/HEATPUMP

Also, if this is a 2-1/2 ton unit can it be connected to a 2-ton outside compressor?

SOURCE: Replaced my 5-year old 3-ton 12 SEER Goodman outside condensing unit with an older 3-ton RUDD condensing unit because of lack of funds. Now the compressor has gone out on the RUDD. Is it better to rep

A new unit will be 13+ seer unless you can find someone that has replaced a compressor or has one left over from pre 2006 stock. Our wise Government with all its resources decided that we aren't smart enough to turn off the lights to save energy, so they chose to end the med and low price lines. And the same bunch of smart ones decided that now R22 because of its chlorien content being bad for the air (5% of what R12 was) so we have R410A and others that no one knows how much cancer or daMAGE THEY WILL DO OVER TIME. So now if you replace your AC unit out side with a new one be sure its compatable with the refrigerant inside and beware soem manufacturers wont stand up to full warranty if you dont buy an indoor coil and rerplace it too.

We get what we deserve in Washington DC and if our guy didnt support this stuf too many other folks guys did. We just dont talk about it enough. AND WE SHOULD. But then again you like me are probably RITCH. So we have to give up our wealth to the government so they can redistribute it and buy more votes. And we can stay working too much to talk about it.

Just burns my back side like a 4 foot flame.

Read tween the politics and you'll get my recomendation.

Buy your self a compressor and get someone qualified to install it or see if the old goodman one will interchange easily.

SOURCE: Hello, I have a 1.5 ton rudd ac/heat pump

Your outside unit is not defrosting. You need to call a service tech to check it out. Defrost board sensor or low on gas. Also you amy have an outside tstat that is not working correctly. Rus

SOURCE: Is there a system mismatch with an American

This must be a heat pump? Sometimes the unit can be more efficient with this combonation. What you are probably hearing is the reverse direction of the
refrigerant going back through the liquid line.

If in cooling sometimes you can hear a gurgling sound going through the expansion valve, sometimes
this is a sign of low refrigerant or the system is fine..

If you recently had the outdoor unit replaced and noise is an issue, check to see if the unit has isolation pads installed underneath the unit whether
it be on concrete slab or on brackets mounted to
house. Sometimes the new units come with compressor that has a jacket installed over it

Testimonial: "Thanks, I was told that the noise at the TRV valve on the air handler is liguid refrigerant (rattling noise) and that the systems are mismatched."

SOURCE: I have a Ruud 2 ton split system and the system

The small line coming in from the outside unit should be warm to hot and the larger line should be cool and sweating with water forming on it. I am taking for granted that the unit was working if so it sounds as if the unit is low on freon. your inside coil should be sweating a lot from top to bottom if it is only cool or sweating on the bottom but less to nothing up top you are low on freon. When very low the unit will stop working just like a broken valve in the compressor. If it is just a little low it will not cool properly and at night it might even freeze the inside coil up.

What are the tons of a RUUD AC HANDLER MODEL UBHA-17J11 SO SFFA SERIAL NUMBER MOO500 03485 and what type of CONDENSER & TONS CAN IT HANDUE WITHOUT PROBLEMS?


You can find the tonnage in the model number which increases by increments of 12, so if the model number is 24 =2 tons. Model number on your a/handler is 17. Thats a ton and a half. Really should match the evap and condenser for the best efficiency. ...

How many tons is a rudd model ubhc-14j06sfd?


I believe the "06" in the model number has been reversed. It should read UBHC-14J60SFD. This would make this unit a 5 ton unit. I hope this helps:) Have a great day!

Bdp541cj024 heatpump need a replacement.


Hi, this is a 2 ton unit. The 024 in the model number tells me this. There are 12,000 btus per ton, so 2xo.12=0.24 which is 2 tons or 2x12=024. Good luck,

I have a Ruud Model # UACC-036JAS. Any idea on


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,
Shastalaker7
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.

What is the size of coil in air handler is it 3 1/2 ton and believe that rudd only made 2 ,3 , 4, 5 , ton coil is this right


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.

Btu's


That air handler can accamodate different size coils. Look for the coil model number. Also you can look at the outdoor unit model number they should be matched up. There is generally a set of 2-3 numbers in the model numbers that will tell you. xxx036xxx is 36,000 btu. tonnage is 12,000 btu per ton so 36,000 btu's would be 3 tons. xxx040xxx= 40,000btu's or 3.5 tons etc.
