Can you tell me what seer this unit is? - Heating & Cooling

Tonnage is 2.5 tons

SEER rating is 10

If this is the model number of the unit, it would be a 2 1/2 ton unit. The seer I couldn't tell you with out seeing the manual. Could be a 10, 12, 13, cant tell with this information. Sorry.

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.

a hard start is not for a fan they are for a compressor and if your compressor need a hard start kit it most likely is not long for this world. most manufactures have a 14 seer line (13 is min) that will with the right coil and furnace match get a 16 seer rating if you have the money this is a good way to go if it is just the fan thats not working i would call another service company or ask that another tech be sent out because if they are telling you that you need a hard start on a fan they dont know what they are doing

My books do not go back far enough to get you the Seer rating, it is a 5 ton unit and as the serial number shows it to be a 1999 model, it is probably a 10 SEER unit, maybe a 12 seer, but not likely, but I can tell you that it was manufactured on the 8th week of 1999.
I hope that I have helped, have a great day.

12000 btu/hr equals 1 ton. The 48 in your model number tells me it is probably a 4 ton unit. 48 divided by 12(000) equals 4. Not sure on the SEER

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.

it is a 4 to 12 seer. the heat strips installed should tell you their kw as they are a separate part from the unit. I am not sure of the age though, sorry bout thay

Yes a higher SEER can help reduce electric costs. However. In most cases this will require changing both the indoor and outdoor units. In other words if you have a 10 SEER matched system and only upgrade the outdoor unit to a 14 SEER you will not get exactly 14 SEER efficiency. They must match.

Before excepting bids on new equipment I would first higher a licensed company to measure the Heat gain/loss from you house. This information will tell you if the current system was originally sized correctly. The improper sizing can lead to high electric bills as well. I hope this helps.
