The second number (8870816941) is probably 867.816941. That unit uses a compressor for a 4.5 ton air conditioner.

If you need more help, reply with additional details.

Earlier I got an answer that a Sears evaporator coil Model# 867 813530, was a 2.5 ton coil. that is what is paired up with the condenser is the coil actually a 2.5 ton or is that a mistake? I was thinking that the 24TE7025900 may have depicted a 2 ton condenser but it is really huge for a 2 ton. The condenser is paired with this evaporator 867 813530, and a 90,000 BTU heater. Now I wonder about the evaporator coil size. What you say coincides with the size of the Condensing unit and the heater it is paired up with. That would explain the problem I am having which is water is blowing around the coil and blowing water out of the drain pan. Pressures are; with 80 deg inside temp, 70/275

I do have some other #'s for the evaporator if this isn't the one you need.

I see the previous answer from Expert Scott that indicates your A-coil is rated at 2.5 tons. That coil was apparently installed within the proper specification to handle the capacity of the outside unit. The problem with water blowing out of the drain pan could be caused by a clogged drain system. I recommend that you check to see if the drain is working properly. You may need to have a technician examine the unit. I provided a link for the Sears Service website below this response. If you need more help, reply with additional details.

Why would they pair a 4.5 ton condenser with a 2.5 ton coil? The drain is clear. I am a certified technician, vocational school with 30 yrs field experience and have never encountered a 2.5 ton coil paired with a 90,000 btu heater and a 4.5 ton condenser, I've seen a lot of condensers paired with a half ton bigger coil, but never a smaller one. The water is blowing through the drain pan, and the unit has way too much return air. I was thinking the coil may be plugged causing air to blow around coil through the drain pan. Unit is an upflow, so a plugged evap coil would cause high positive pressure between the fan and coil. The unit appears to have been leaking for many years, fan motor has been replaced, I haven't checked specs on the motor, but wondering if they replaced motor with a higher RPM motor than the original 1075. Plan to pull the coil to check the pan and clean the coil this week. It just seems like a 2.5 paired with a 4.5 ton would cause some odd pressures, and wondering if the 2.5 ton coil can handle the air flow of a 90,00 btu htr. I slowed the fan down to low speed with no change in pressures, but the leaking did slow down somewhat.. My other thought being that the coil is plugged enough to cause blow through. Possibly over the years the coil started getting plugged and some one just added gas to bring suction pressures up.

I'm sorry for the confusion. You are correct, a 4.5 ton condenser will not work with a 2.5 ton evaporator. However, the numbers listed for the condenser, do indicate that it is a 2 ton unit. So this system is paired correctly. As for the water blowing out, it will usually be caused from a dirty evaporator. Since you are a technician, you probably have access to some coil cleaner. I recommend cleaning the coil and it should help with this type of problem. I hope this will help you.

I have to pull the coil to get to it to clean it, but I didn't want to pull it if it was an undersize coil, because I wasn't sure if it would correct the problem. Thank you so much, now I feel comfortable cleaning the coil and checking the drain pan. You guys have been a great help as I haven't been able to find specs on those #'s. I appreciate it very much.
