So the Goodman HVAC system that was installed after the late great hail storm, on the insurance company’s dime, needs some service. I guess. Turned it on at 7:30 this morning. After it had pounded away for an hour, the thermostat recorded a one-degree rise in temperature (yeah: that’s 1 degree).
It’s been making some annoying outdoor noises, but Goodman runs noisy anyway, so I haven’t paid much attention.
Fortunately, the Goodman has a 10-year warranty on parts & labor, so this misadventure shouldn’t cost me much.
The warranty runs out in 2021, which, when you think about it, ain’t all that much longer. That’s only 5 years from now…
Replacing the type of air-conditioning & heating system needed in Arizona is an expensive proposition. For a house like mine, cost is likely to run $4,000 to $8,000. Or up: SDXB paid $5,500 for a system serving a smaller house than mine.
And in the New Ecologically Correct and Internationally Traded Environment? Not very effective. My Chinese-made heat pump, for example, freezes up when exterior temps drop into the 30s, at which point it blows ice-cold air into the house.
Over the past few years, the way I use my house has changed. A lot.
I used to spend most of the daytime hours in my office, working on a large and powerful desktop computer. Then my back went out. Now I can NOT sit in a desk chair any more than a few minutes without enjoying limp-inducing hip and back pain (and yes, I have tried all sorts of ergonometric chairs). The only way I can work for any length of time (and “work” for me entails hour after hour after interminable hour focused on arcane, mind-numbing copy) is to recline in an overstuffed leather chair with my feet up on an ottoman and a MacBook on my lap.
That chair is in a large room that comprises a family room, dining area, and kitchen. Two doors opening into the backyard accommodate the dogs’ comings and goings. And…that means that instead of moving around the house — from the office to the kitchen to the dog exits and to the dining area and back to the office — I spend most of my time in one centralized area: a single room, really.
At night I go back to the bedroom. And that’s about it: in fact I’m only occupying two rooms of a six-room house (eight, if you count the closet-like bathrooms).
So lately I’ve found myself wondering…why the hell am I air-conditioning and heating this entire building when I’m living in about a third of it??
In the wintertime (because it doesn’t get very cold here), it’s fairly easy to live without central heating. A plug-in space heater will make a work room cozy enough, and an electric blanket or throw set on “low” will get one comfortably through a two-dog night.
As it develops, there are central HVAC systems that can be persuaded to “condition” the air only in a given space within a building. These are dubbed “ductless air-conditioning systems.” Some of them are…yup…pretty Third-World. But that doesn’t seem to matter, since the Funny Farm is now situated in the Third World anyway. Probably much as your home is or soon will be.
One of these is made by Mitsubishi. It’s very expensive. On the other hand, simply replacing one’s existing AC system with a new unit has grown into a ludicrously costly proposition. I’ve actually had one HVAC vendor propose something near 10 grand to replace my system, using its aging ductwork.
The beauty of the Mitsubishi system is that you don’t have to stick ugly portable AC units in your windows. In my house, that would be impractical, because all the windows are sliders. There’s no way you could install a window AC in any of the rooms without (expensively) replacing the windows, too. if you even could: the openings are too wide for double-hung windows.
The un-beauty of the Mitsubishi system is that it’s breathtakingly expensive. Not only do you have to cut holes in exterior walls to install the ductless vents, you also have install a central system that costs as much as or more(!!) than a traditional central air-conditioniong system. It would be pretty damn expensive. Indeed.
On the other hand, if you were only air-conditioning the rooms you use, and if you only use a couple of rooms on any given day, and five or six months out of every twelve you needed little or no air-conditioning either heat or cool, it wouldn’t take long to recoup the installation cost. And the environmental footprint, if anyone cares about that anymore in the Age of NeoHitler Trump, would be far, far smaller.
So…there’s no hurry to make this decision. The Goodman system presumably will run at least until 2021. It may even run longer than that. But into the future: ??? It behooves one to keep an eye on new developments.
