13 SEER is now minimum in my neck of the woods-NC. If you plan on replacing the duct work with the unit, spring for the extra savings in a 16 SEER. If you are going to reuse the ductwork, get pricing on a 15 SEER. The 15 SEER is a better built unit than the 13 SEER. If you plan on staying in the house for 10 years or more, it is worth the investment. The reason for the ductwork question is the higher SEER units depend on EVERYTHING IN THE SYSTEM being right, especially duct leakage. If you are handy you can seal the ductwork yourself if you can buy duct mastic locally. Cloth duct tape won't do! There is a metal duct tape with a mastic backing that works but it is expensive. If your home has mostly flex duct, good luck; craftsmen used to make metal ductwork, but it is hard to find anyone able to do more than a basic metal box anymore! a computerized load analysis program can take into account the type of ductwork in your house and get a good estimated load and provide a duct layout- so be sure to get a written copy of the load estimate from your contractors. these programs ain't cheap, so don't share the contractor's paperwork with another lower priced contractor, let them earn their money!

Subject: [DIY] Re: Heat Pump
Hi, how much more are these seer 19 or 20 or more cost then ones at 16, or 13.
When I bought mine, the difference when I ran the numbers weren't going to save for 15 years., at 5.00 a month for only a few months,
a year, to the thousands more they wanted for a seer 13, vs. 16.
In az the contractors take advantage of people. They have the state offer a rebate, of 1200. per unit, if its over 13 or 15,
then charge you 3K, more than it has to cost.
All because they belong to the az APS program, and they have to pay to be on it. Or the consumer doesn't get the STate tax rebate of 1200. even if you buy the unit, and have papers to prove it.
The state forces you to use one of their contrators, doesn't stand behind the install. The contractors charge 3K more, which brings a unit up to over 7-8K
vs. 5K.
How is that saving.
I ran a program where you put in your rate of electric, and the seer etc. and compare the units,
I couldn't see a cost savings to spend 3K more and save 5.00 max, per month between the two units,
I like to conserve, and that didn't make sense.
I have another house now, and we have a 12 seer and the bills are not enough to justify spending thousands more to save very little.
If anyone does get quotes on these units, at 19seer I would be interested in hearing how much they are for a 4 and 5ton unit.
sincerely,
Joan
ps I had a trane ...... it was great.
