I recently made an "on the spot" decision to purchase a new AC unit for my home when faced with the cost of repairing the old unit. Of course NOW, I'm trying to research if I made a good decision.

I have a 1200 sq ft home that is 15 years old and is fairly well insulated. In comparison to my friends with similar homes my utility bill is pretty low. I live near the southern tip of Lake Michigan, so I figure I only need AC 3 months out of the year tops, and I am conservative about usage.

I was sold a 2 ton Goodman 13 seer AC installed for $1400.00.

First is 13 seer that bad? I figure I need to consider the cost of a higher seer unit for the amount of time I actually use it. Five years ago when I bought the home a 12 seer wasn't considered all that bad.

For that price you must have got the outdoor condensor only and that is a good deal. 13 SEER is the standard and you are good with that, in Florida/Texas they would appreciate 15 SEER or higher.

The unit that sits outside. The freon lines and evaporator coil inside the furnace are probably the original. A complete system starts at $2500 - $3000.

From Wiki
The annual total cooling output would be:

24kBTU/h * 8 h/day * 90 days = 17.3E5 BTU
With a SEER of 12, the . . . electrical energy usage would be about:
17.3E5/12 BTU/W·h = 144kwh
and 133 kwh for SEER of 13.

But your system may only run half of the 8 hours each day.

Do these cooling degree days sound about right?

6/1/08 234
7/1/08 330
8/1/08 275
9/1/08 140
10/1/08 29
11/1/08 7
12/1/08 0
1/1/09 0
2/1/09 0
3/1/09 4
4/1/09 21
5/1/09 61

I'd be more worried about reliability going down and parts cost going up as SEER goes up.

The OP was asking about price. Your stuck in heat load and U factor gear from talking to Been.:laughing:

24kBTU/h * 8 h/day * 90 days = 17.3E6 BTU

1,440 kWh for 12 SEER, 1,330 kWh for 13.

Clover, you should charge more $$ LOL. :yes:We can easily sell Lennox units for $3000-$4000. We are a VERY well established company and people are willing to spend more for that. I guess it depends on what your market will bear.

I used to be able to do numbers. :icon_cry:
Maybe you didn't have enough HDD samples to be within your 2% statistical accuracey. :laughing:

Nah, this time I'll blame low batteries in my calculator.
LOL... yea. I've had weak batteries cause trouble with meters and calculators also.
