And you thought your installation was bad...

Just saw this hilarious post.

Reminded me of being there and watching both the installation process, and the results - and I must tell you, those are not for the weak of heart.

The installation I saw was on the second floor, and they already had to use a crane. However, as the floor goes up, so does the price (and the danger). I don't think there are any cranes (at least that a regular person can afford) that can reach above, I'd say, fifth floor - and I've seen mini splits installed all the way up to 16th floor (that's the usual height of a residential high rise building).

The only way I can think of is to use professional climbers to haul the condenser up and fasten it to the wall, but then there's a question of connecting it and charging the system, which requires HVAC training and certification, and not always can be done from inside...

Things sure are interesting over there.

SketchUp + Energy Performance, part 4

(part 1)
(part 2)
(part 3)

I think I'm going to stop referring to HVAC-Calc, lest there be any confusion...

Anyway, the saga continues - and here's the last installment: See your building's energy performance - and note, it's free.

Let the fun begin.

Real Life Numbers

Had to shut off the workshop for a month. 850 sq ft that I didn't have to cool to 82°F with the average ambient temperature of 92°F resulted in $75 savings on the electric bill.

Of course, this number is not exact by any stretch of imagination, but it'll give you a good ballpark of what your actual HVAC expenses are, and give you some food for thought about the actual ROI on your HVAC related investments.

Who Needs A Thermostat, Take Three

There is a new application for Google Android platform, AutoHTN, which, among other things, purports to control the home HVAC.

Told ya...
