Before in the past when regulations upped the minimum seer allowed, did the previously higher seer models that than became the base evenutally settle to an economy model like price? I assume once the 10 seer condensors were pricey compared to lower seers before 10 became the lowest allowed. Will the 13 become cheaper as the standard builder model or is their inherent costs that will keep it at the current price?
Perhaps I am looking at it like computers that become less efficient compared to the newer advanced ones and lose their pricing power but in this case it is the government pushing the change. I ask this question as I have 4 apartment units and another 4 I take care of for my mother that I would like to add AC to (we're in Ohio) and am wondering if I should buy the 10 seer units now although I would prefer to add AC units a couple at a time due to the great expense of buying 8 at once. Would welcome your opinion.
