Ok, so I suspect it’s hot everywhere. However, it’s really hot here. Here’s a screen capture of my Gnome weather applet.

104 °F! Luckily, though, the humidity has dropped from the high 90’s earlier this week.

I thought I’d upload a photo I took of our weather station in the office. My mobile (L6) has a lousy camera so apologies. What a difference, though, right?

It’s been warming up in the Bull City and our house is not impervious to the temperature apparently. Early on I had assumed that our spiral stairs to the partially finished attic would be a bane to the efficiency of the environmental controls in the house. Ah, how true. Although I suspected it was not the fault of the new HVAC system I called CWJ, the company that installed our new gas pack 3 months ago. The good news in this story is that the CWJ’s service was great. I called at around 7PM and they were out in about 20 minutes. Very thorough, very polite, and willing to talk about things unrelated to their system that I should do to improve the environment in the house. Try that with American Home Shield.

Which brings me to my next point: Attic ventilation. Why hasn’t anyone in the 64 years since my house was built think ventilation might be important? No idea. Perhaps the finishing of the attic has exacerbated things. Either way, I’ve got some work to do. First we’ll insulate the vestibule at the top of the stairs, then we’ll install some soffit venting to compliment the continuous ridge vent, and we’ll think about prying up the planking in the attic to increase the insulation between the attic and the ceiling below.

I’ve had this fantasy of blowing insulation into the walls of the house, too. However, I don’t want to damage the original asbestos siding and I hate to drill holes all over the plaster interior walls so that might not happen. Asbestos siding is actually super-high quality stuff and never needs to be repainted. Replacement windows are out. Our windows are lovely and new windows don’t let light through in the same way.

We finally reached the limits of our patience with our home warranty company, American Home Shield. I’ve taken so many vacation days to meet service people that it started looking cost effective to replace our 15 year-old gas pack. I thought someone else might find the details useful so I’ll spell them out here. For reference, we have a 3 bedroom, 1078 square foot, 1943 cottage. We have original single-pane windows, which are breathtakingly lovely but less than ideal for thermal efficiency. Our ducts were replaced sometime in the last few years. We acquired 4 bids. The estimates follow.

We chose CWJ, but only partially because of the price. Our decision worked out like this: Brown Brothers and Michael Duke (not listed) inspected the existing unit while we were out and we never met them. We eliminated Brown Brothers and Mechanical Man because they were the highest bids, although I liked Mechanical Man. Michael Duke was mid-range, but we eliminated him because he seemed to do it on the side and he submitted a bid without meeting us. We liked Home Energy and probably would have chosen them, but we got their proposal too late.

The choice, in the end, was between CWJ and One Hour. Both were recommended to us and both were mid- to low range pricing. One Hour provided us with two references. Both said positive things about their service and both references turned out to be personal friends of the One Hour salesman. A colleague helped make our decision for us by detailing her experience with One Hour. She said the salesperson (One Hour was the only company with dedicated sales staff) would say anything and her follow-up service was lousy. I also caught the salesperson in what I will politely call a discrepancy. These two incidents confirmed the tell-you-anything, “I’ll sell you a car today!” feeling we were getting from their sales people.

We used CWJ. They were recommended by several people on the Duke Park listserv. They were fast and friendly, but they left our yard a mess of cigarette butts, soda cans, insulation, and chunks of metal. Also, we’re a little dismayed that a week later no one has called to ask how it’s working out. For ~$4,000, I’d expect a nice phone call checking to see if we’re happy. We’ll see how it works out. Clearly, though, this unit works much, much better than our old unit. It remains to be seen if moving from a 15 year-old 10 SEER unit to a new 13 SEER unit will save us money on our energy bills. Most anecdotal evidence I’ve heard relates savings while using the furnace, which we do little of.
