Whole-home humidifiers in Paeonian Springs.

Paeonian Springs is a hamlet, not a subdivision. There are only a couple of hundred homes, all of them detached, and the Census counts too few to give you a clean percentage. The direction is clear enough: propane is the most common heating fuel, with electricity after it, and almost nobody has gas. So the first question on the phone is what the furnace burns, and the second is where it sits.

A propane furnace behaves like gas for this purpose. Its supply air is warm enough that a bypass model can do its job with no fan of its own. A house on a heat pump, on the other hand, wants a fan-powered unit because the air is cooler. Neither choice is complicated, but the wrong one runs poorly all winter and nobody figures out why.

Houses here are a mix of old frame homes and later builds from the 1980s and 1990s, and those years give two different dry-air problems. The older ones lose moisture through the walls. The newer ones keep it, and can end up with damp windows if the humidifier is set to the number on the box rather than the weather. We set it by the temperature outside, and show you where the dial is.

If your house has a humidifier from years ago that no longer works, the $99 visit tells you whether it needs a new pad, the valve opened or the control reconnected. In a small place like this, people also ask us for a second opinion on a quote from somewhere else, and we are glad to give one.
