Mini-Split Deep Cleaning in Freedom
Electric utility: Eversource / NH Electric Co-op (split territory) · Carroll County
Freedom has no gas main. Never has. So every house in town heats with some mix of oil, propane, wood, and electricity, and when the heat pump rebates came along a lot of people here hung a mini-split in the main room and kept the stove too. Sensible. The mini-split carries the shoulder months and the stove takes over when it gets properly cold. But that means the indoor unit spends four or five months breathing the same air as a firebox.
Here’s what that does. Every time the stove door opens there’s a puff. Every armload of wood drops bark and dust. Most of it is too fine for the mesh filter on the front of a mini-split, so it rides straight through and lands on the coil, and if the unit happens to be running in heat mode at the time the coil is warm and dry and it just bakes on. Come summer the same coil goes cold and wet, and now the soot is glue for everything else.
A fair number of the year-round houses here went up during the 1970s, when the town nearly doubled — 387 people in 1970, 720 by 1980. Ranches and capes from that run were built for baseboard or a single stove, no ductwork, which is the exact house a ductless mini-split was made for. The village houses on Old Portland Road are older again. Either way, the unit on the wall has usually been there six or eight years by now, and nobody has ever looked behind the coil.
Freedom Tip
When you rinse the filters in January, look at the color of the water. Gray is house dust. Black or brown is stove soot, and it means the coil behind them is collecting the same thing — worth putting the spring clean on the calendar now.
What comes off a coil in a wood-stove house
First the room gets protected. Electronics bagged, a rinse bib sealed under the unit and run into a bucket, drop cloth down. Then cover off, filters out, louvers out. In a stove house the first rinse off the coil is usually close to black, not gray — that’s the soot letting go. We keep going, cleaner then water, cleaner then water, until it runs clear. Five passes isn’t unusual.
The blower wheel is the bigger job. It’s the long plastic drum behind the coil, and each vane on it holds a ridge of packed dust about the thickness of a credit card. On a unit that’s been near a stove the ridge is darker and stickier. It comes off with a brush and patience, vane by vane. No shortcut that we’d trust.
Then the pan, the condensate line, the housing, and the louvers, and then outside to the compressor. Out back in Freedom that usually means pine needles packed against the fins and a dusting of road grit if you’re on a dirt road, which a lot of the town is. The outdoor coil gets washed through in the right direction, gently. Then it all goes back together, runs, and we check the air coming out against the air going in before we load the truck.
For one indoor mini-split plus the outdoor compressor it runs on, it’s $199. A second or third indoor mini-split in the house adds $119 apiece. A second outdoor compressor adds $69. Nothing under $199 per visit. A coil black with stove soot costs exactly what a lightly dusty one does.

Common Questions in Freedom
Should I stop running the mini-split while the stove is going?
No need. Just keep the filters rinsed every couple of weeks through stove season, and have the full clean done in spring once the stove’s out. Shutting the mini-split off doesn’t keep soot off the coil anyway — it settles there whether the fan is turning or not, only slower.
How often in a house that burns wood?
Once a year, in spring. Soot loads a coil faster than plain house dust, and it makes whatever lands after it stick harder. If the stove only gets lit a few weekends a winter, every two years is reasonable. We’ll tell you which you are after we see it.
Is the soot on the coil a fire risk?
We’ve never seen it be one, and we wouldn’t frighten you with it. What it costs you is airflow. A fouled coil moves less heat, so the mini-split runs longer and your electric bill shows it. On the Co-op or on Eversource, that’s money either way.
You come out to the Maine line end of town?
Yes. The village, Ossipee Lake Road, the roads up toward Cragged Mountain and over by the Porter line — all normal. If you’re at the end of a long camp road, mention it when you book so we know what we’re driving into, especially in mud season.
