Quick question. My realtor just said a 3500 sq ft would cost around $400 a month to cool in a older home (20 years ago build) and a new home would cost $150. She attributes this to better build and insulation. Is the difference that dramatic? And how much of that is actually due to the newer AC unit. I wonder if I can get a older home, improve insulation, get new AC and get the same effect.

You absolutely can and, yes, the difference can be that dramatic. Before you make an offer ask for the last 12 month electric bills, you will know it. However, actual usage is more important than dollar amount. Dollar amount depends on the power plan that the owner is on.

You can choose to upgrade the insulation but whole house upgrade can be little expensive. Most important places to improve insulation will be in attic, wall next to attic (older homes have no indulations here), and west facing walls. Put some radiant barriers on the roof and it should all work out.

Another option is to install solar panels. You will have a better ROI if you are paying $350/month.

Seer 16 A/C and higher will be good with regular tune-up.

how much would it cost to do all those upgrades? I'm trying to figure out if it even pays for itself within 10 years.

Call the insulation vendors. My guess is solar panel installation will run you cheaper than those upgrades. Somebody once mentioned that upgrades can be around $15K (not including price of 2 A/Cs) but that is really a ball park.

I live in an 1800 sq ft ranch built in 1957. We just got the current electric bill from Reliant. It's $103.76 for the month of August. We keep house at 70° from 8pm-7am, 79° from 7 am-4pm and 75° from 4pm-8pm.

Previous owners had completely remodeled so we have newer windows(installed in 2010). Have no idea what insulation is in our walls, but when we moved in we paid about $500 to have a company come in and blow added insulation into our attic. Our A/C is a 14 seer unit. Saw no reason to go higher as the 20 yr old inefficient unit was still only giving us $120 energy bills when we moved in. No reason to pay extra for 15,16,17 seer IMO.

In winter last year, the electric bill averaged $32.


We're very happy with our electric bill. Our water bill, on the otherhand, was more than the electric
