I have the same one.
I can't read the label on the condeser but it is probably 3 Ton.
since the model number has 42, i would say it probably is a 3 1/2 ton.
My opinion would be Rheem as Lennox is more difficult to get parts for.
tThat would Rheem
Yes, Home Depot sells Rheem tankless water heaters. However, the Rheem company website also offers them and the company may have a better price. I would also look on Amazon.
The AHU unit does not have a tonnage rating, since all AHU`s can accept a number of different tonnage evaporator coils. Your best bet would be to post the condensing unit model and serial#`s.
According to my HVAC guys, your Ruud Achiever 9, UAFD-024JAS air conditioner condenser is a 2 ton (24,000btu) model which would be indicated by the 2 in the last part of the model #. The company that I'm referring to is a reseller/installer of Ruud & Rheem (their parent company) heating and cooling equipment and systems. I have the same exact model # behind my house.
Not clear on "cracked condenser", but a bad condenser in the distributor would cause the points to wear out quickly, which could easily keep the truck from starting.
The AC condenser would effect the performance of the AC system in the car.
if i had the answer would i ask you
A good place to start would be the online website for you local newspaper. Another place you could look for a used 1.5 Rheem air conditioner is on craigslist.org.
The temperature of the water leaving the condenser would depend on the amount of heat removed from the water in the condenser. Without this information, it is not possible to accurately determine the temperature of the water leaving the condenser.
Increasing the size of the condenser, would help the system be cooler in very hot weather. Usually the condenser in the vehicle is as big as can be fitted.
