Mini-Split Deep Cleaning in Rumney
Electric utility: NH Electric Co-op · Grafton County
Rumney sits down in the Baker River valley. The river runs west to east straight through the middle of town with Route 25 beside it the whole way, and there is high ground on both sides — Rattlesnake Mountain to the north, Carr Mountain topping out at 2,960 feet and the highest ground in town. The houses in Rumney village, Rumney Depot and West Rumney sit at the bottom of all that, and plenty of them still burn wood or pellets. This was a fifteen-sawmill town in 1859. The habit outlived the sawmills.
What that does to a mini-split is specific. Every time a stove door swings open, fine ash goes into the room. The mini-split is up on the wall pulling that room air across a cold coil all day long. Ash particles are far smaller than anything a mini-split filter is built to stop — those screens catch lint and pet hair, not combustion particulate — so the ash goes straight through, lands on the damp fins and on the blower wheel behind them, and packs down a little tighter every winter.
Almost nobody calls us about dirt, though. They call about heat. The unit runs and runs, the room never quite gets there, and the first thought is always that it is undersized or on its way out. Usually it is a wheel carrying a sixteenth of an inch of packed grey on every single vane.
Rumney Tip
Book it in spring, after the last fire of the season. Clean the wheel in October and you are putting a clean wheel straight into six months of woodsmoke. Clean it in April and it stays clean through the summer, which is when you are actually running it for cooling.
What a sixteenth of an inch actually costs
A blower wheel is a long drum with several dozen small curved vanes around it, and each vane is a fan blade. The curve is the whole design. Fill that curve in with an even grey layer and you have the same motor at the same speed moving noticeably less air. Less air over the coil means the coil cannot hand its heat off to the room, so the system runs hotter and longer for less output — and in a January cold snap it starts throwing defrost cycles it would not otherwise need.
So there is no “filter and spray” option on our price list, because it would not touch any of that. We hang plastic, bag the electronics, seal a catch bib to the wall, pull the cover and louvers, and get the wheel out. Coil flushed front to back until what is running into the bib stops coming off grey. Wheel scrubbed vane by vane. Pan down to bare plastic, condensate line flushed end to end, and the outdoor compressor combed clear of pine needles and whatever else the valley has packed into the fins.
Back together, run in heat, and we stand there and feel what comes out of it before we pack up. A wood-heat house in this valley generally wants this every other year rather than every year. If yours is in the off year we will say so and leave. Might cost us the job. That is fine.
One indoor mini-split with its outdoor compressor is $199. Each additional indoor mini-split in the same house is $119, each additional outdoor compressor is $69, and $199 is the minimum for a visit. Condition does not move the number. A tidy three-year-old unit and a ten-year-old one packed solid with pellet ash cost the same, because we do the same work on both.
- Runs all day in January and the room still never comes up
- Woodstove or pellet stove in the same room as the mini-split
- Grey film on the louvers, or a grey smudge on the wall underneath
- Weaker airflow out the bottom than there was two winters ago
- Defrost cycles kicking in more often than they used to
- Nothing ever taken off the unit except the two filters

Common Questions in Rumney
Won’t the filters catch the wood ash?
No, and that is not a knock on the filters. A mini-split filter is a plastic screen sized to stop lint, dust and pet hair before any of it reaches the coil. Wood and pellet ash is an order of magnitude finer than that. It passes straight through, sticks to the damp fins and the wheel, and builds from there.
How often does a wood-heat house in Rumney need this?
Every other year for most of them. A house with a stove going daily from November to April, pets underfoot, and a mini-split covering the shoulder seasons loads up faster than a clean-heat house and may want it annually. We look at the wheel with a light and a mirror and tell you which one you have.
Can I pull the wheel myself?
You can, and some people do. The hard part is not nerve, it is the catch. Without a bib sealed to the wall you flush the coil and that grey water runs down your drywall and into the floor. That is the call we get most often after a do-it-yourself attempt, and the drywall costs more than we do.
Will cleaning it bring the heating bill down?
Some, usually, though we will not put a percentage on it, because the honest answer depends entirely on how bad the wheel was. What you will notice straight away is output — more air out the bottom, the room coming up faster, and the unit cycling off instead of grinding all evening.
Do you cover West Rumney and Quincy, or just the village?
All of it, same visit, same price. West Rumney along Route 25, Quincy out by the bog, Rumney Depot, the village itself, and up Stinson Lake Road. Rumney is forty-two square miles and we would far rather do a whole road in one morning than drive out for a single house.
