The only important part is before the last A. It gets broken into two parts, xxABA, and *** (where x is any number) 24ABA:
24A = A/C (24H would be heat pump)
B= Base series, C would be Comfort, P would be Performance and N would
be Infinity. (B, C, P, N in that order gives you more bells and
3rd letter = A (puron) or B (R22). 342:
First number = SEER 3 = 13, 6 = 16, 1 = 21.
42 = btu in thousands (18-60)
This means that your unit is a 13 SEER, 42,000 BTU base-model Air Conditioner which uses Puron (R410 refrigerant).
10 seer was the most efficient for the older generation units and in 1992, it was required that any unit has to have 10 seer or greater. The least efficient seer rating you will find on any new unit will be 13 seer which is a lot better than 10 seer and will save you almost 30% in energy cost. As of lately, they have made units available that are up to 20 seer or more, but they are pricey. I know you said you just had the unit installed, but from the model number, I'm assuming it is an older unit? If new, then it would have at least a 13 seer rating. Hope this answers your questions!
Your going to need to know the age of the unit. If its less than 5 years old, its most likely a 13 SEER. If its anything more than 5 years old, its most likely a 10 SEER. If its anything over 10 years old, its most likely an 8 or 6 SEER.
Remember, that a unit will loose an average of 1-2 SEER for every full year of operation. This is just due to age, wear and tear, and usage.
So, if its a 10 SEER unit that is 7 years old, you could say that it is about as efficient as something in the 4-6 SEER range.
Your problem is that your 13 seer outdoor unit is not compatible with your 10 seer indoor unit, even though the tonnage is the same. The metering device on 13 seer indoor units is different. Most 10 seer indoor units do not have an expansion valve. When you change from a 10 seer outdoor unit to a 13 seer outdoor unit, you must, at the very least, change the from a fixed-orfice metering device to an expansion valve.
is this unit real old ? it does not come up in my book . the btu is 30000 that is the same as 2.5 ton it may be 6,7 or 8 seer i dont think its a 10 seer because the 10 seer units are listed and yours is not . if this sounds wrong please look up the mod # again and post the ser # too ......... Please if this answer helped , please rate this 3 or 4 stars . and keep me in the paid answer department . A 1 or 2 may knock me down into the unpaid ranks. Thanks Cactus Bob .
