More HVAC stuff

eve_primeToday I “signed” the paperwork to get the new heat pump, but it may take 3-4 weeks… also they have to schedule a “permit” person and someone to double-check the measurements between now and then. Last night it only got down to 78 in my bedroom, although outside it was in the mid-50s, so today (given that it got up to 85 in here when it was 91 outside) I decided I would sacrifice the pollen-free status of my bedroom and open the window for a couple of hours before bedtime. It's around 63 outside, and I had imagined it would cool the room right down. Well, without a cross-draft, that’s apparently not going to happen. At 1:30 am it was 83 in here, and now, at almost 3 am, it’s dropped to… 82. I should find a fan tomorrow and see if it helps.
(Yesterday I bought a handy digital ambient temperature thermometer. I also can report that it’s 3-4 degrees warmer upstairs at J’s house than it is downstairs.)
Given that we’re going to have at least a week of 90+ weather, starting Friday, I had better accelerate the project of figuring out how to sleep in J’s guest bedroom. I should measure the window so I can start doing more to make it dark enough in there for me. (I can’t possibly sleep in his own bedroom – he needs it light in there so he can wake up, and he needs to wake up about four hours before me, which seems pretty disruptive.)
Oh right, I was going to report about the costs. I had two options: a standard model like I have now, which is either on or off, and an “inverter driven” model that is more energy efficient and goes at various speeds. The base price for the standard model plus installation is around $13K, and I’d get a discount for paying cash, so it would be $12K. The base price for the fancier model is about $17K, but there are various rebates and tax credits for that one, so although I have to pay more than $14K up front, the net cost to me is about $15 less than for the standard model (assuming the standard one doesn't also qualify for the tax credit? Maybe it does?). I just have to wait on the rebate from the manufacturer and the tax credit. My electricity bill should drop a bit, too. I went with that one.
Even though my sleep was a bit messed up last night, I did get enough rest that I was able to join them downtown for dinner. Our friend JC was visiting from Iowa!
