what is the difference between a 12 seer and 15 seer air conditioning unit?

Question

will i be able to save a lot more money going with the 15 seer on my utility bill

Answer 1

do you have a 12 seer now? if you don't have a 12 seer now. then don't bother getting one.
the seer rating changed at the beginning of '06 and 12's are no longer being manufactured.

if you have the money to do the repair then I would go with the 15 seer, it will pay for itself over a few years. otherwise your minimum will be a 13 seer.
(unless someone "happens" to have one or they're feeding you a line)

Answer 3

12 Seer

Answer 4

SEER- stands for "Seasonal Energy Efficiency Ratio."
This can be a very confusing term.....however I will try to explain.
First off, the minimum SEER unit which can be purchased now is a 13 SEER unit for residential.

In my region (Pa, NJ, De) I explain SEER as the following:
SEER is a measurement of the efficiency of the unit compared to how many days the (A/C) shall be running.

If you live in area where your A/C usage is only a few weeks, the benefits of a high effeciency unit are slim because your ROI (return on investment) are extremely lengthy. If you are like me and leave your A/C on from spring to Fall, Then absolutely it will be worth it.

As an old general rule for my part of the world, starting from 10 SEER.....it would cost you approx. $35 less in a "cooling season" to operate a 12 SEER than a 10 SEER. Add another $35 to jump to 13 SEER. and so on.

The issue is.......how long will your "cooling season" be this year?

Hope this helps!

Do the math. Use the national average of $0.12/kwh. Assume you run the system for eight (8) hours per day. The difference is 23% - that is, you will spend 23% more on the less efficient system. Start with that in mind. A 13 SEER unit will cost $0.11/hour to operate per ton. A 16 SEER unit will cost $0.09/hour to operate per ton. In a typical 1,000 hour season, that comes to $21/ton. Given that you have a central unit, it will likely be 3 tons or so. Making the savings $63/ton at that price per KWH. The payback may be all of 12 years, but at the same time, you are doing less environmental damage, the unit will easily outlast that 12 years, and it will continue to pay you thereafter. if you use the system more than 1,000 hours per season the payback may be faster. Less, slower. The price of power is not going down, by the way. In any case, $800 seems high for the difference - shop around some more. Typically the differential is less than 10% - at least around here - for the equipment, and the installation is exactly the same.

Answer 6

the higher the seer number is the more efficient it is
if you had a 12 seer unit and upgraded to a 15 seer unit you will definitely notice a difference on the bill it will not be much but it is savings

Answer 7

3 seers

Answer 8

about 3 seer

Answer 9

It's probably not worth it, although it ultimately depends how much you'll be running the AC and what you're paying for electricity. One rule of thumb I've seen is that each SEER value equals a 5% energy savings, so you'd be looking at a total of 15% energy savings. One other factor to consider is that the higher-efficiency unit might qualify for a one-time tax credit ($300 if I recall correctly), which may or may not tip the scales.

Answer 10

3 seers?
