Need help convincing father to buy a new AC unit!!!!!!

post #1 of 11
Thread Starter 
Okay, so here's the deal: I'm trying to convince my dad to buy a new AC unit because during the spring/summer times, our house is at an average temperature of 78 degrees Fahrenheit; during the summer it regularly goes to 80+ degrees. The thing about this is that he refuses to turn on the cooler because he says it costs too much. This is a very bad thing for me and my PC whenever I'm at the house wanting to OC or play games, and now that I have a Fermi card things are only going to get worse. It's gotten to the point to where I'm considering WC'ing my cards, but I don't want to until I at least try this.

Anyway, here's all the info I can provide you with: I have 2 pdf files attached here, one including the current AC unit specs (the CPLJ60-1A - it's like 12 SEER), and the second of one with an 19 SEER unit (the ASXC18
0361A) just for comparison's sake. Our electricity rate is $0.131 for every kWh. If you don't want to look at the pdf's, I have screenies you can look at.

So, correct me if I'm wrong, but with our current unit, we're spending anywhere from $0.61 to $0.64 an hour on the AC alone, right (depending on what evaporator coil we have - I don't know how to find out which one we have)? And for the ASXC18, we would be spending anywhere from $0.25 to $0.27 an hour. BTW, my calculations are based on this right here, and I'm taking the highest BTU/SEER and lowest BTU/SEER to compare.

Does that seem right to you guys? The difference makes me want to believe I messed up here somewhere, but maybe I did do it right. Anyway, is there anything else I should consider when bringing this argument to my dad?

Another thing to remember is cost, the cost of a new unit ranges from $3k+. And depending if you need a whole system. I'm looking at replacing the AC system in my house, its 20yrs old, the best quote I've gotten is $8k, that for the whole works.
So, in the meantime, yes it's just easier for me to keep my AC set to 75-78*, even though the house may hit 80* in the summer here.

So, if you really want him to replace it, you need to find out actual cost for the replacement, install costs and any other fee's, adjustments involved. Then prove then how that investment will return to him, or pay for itself. IE: Cost is $6k up front, but compared to current monthly costs, the unit would pay for itself in 2yrs type deal.

Right, but if I can show him that with the extra money he'll be saving up, he can actually pay for it a lot sooner than what he might think. I'll have to do a few more calculations though, like how often we use it during the summer - or how often we should anyway, lol. I'm guessing like 8 hours, right?

Just depends on how well your house is insulated, if there's certain hot spot areas, areas that are hard to cool because of limited ducting.
Another thing to note, is it is tax deductible next year, depending on unit purchased.

Hmmm, so only use it while I'm gaming, ehhh? This is something I should seriously consider, but I still want to get my father to consider a new AC unit. Perhaps I still have a lot of thinking left to do, because I don't even know how well insulated our house is, so maybe I should convince him to do that first if we really don't have that?

Thanks for the tips though.

Insulation does help quite a bit.

Another thing is to block off areas that don't need it and maybe leave the blower running so it's all circulated.
