Please help me identify my AC unit
hello all. I have a Sears air conditioning system in my house that is at least 20 years old. My ac guy says i can get at best another two years out of it if we replace the evaporator coil. Unfortunately, it's so old we can't tell if it's a 3 ton or 5 ton system. The only model number on the unit is 36TEW7986010. i called sears directly and they have no idea. If anyone can help me in identifying the tonnage i would be very grateful!
thanks

Well if he has any experience then he should know he can get the numbers off of the compressor and that will tell him the size. other clues- what is the square footage of your house? What size is the circuit breaker that supplies the outdoor unit? What is the horsepower of the indoor blower motor? What size is the indoor blower wheel? If you indoor coil has a TXV, he can get the numbers from it. If the indoor coil has an orifice, he could even back check the size of the orifice. Offhand, I think it's 3 tons.
