Mini-Split Deep Cleaning in Moultonborough
Electric utility: NHEC · Carroll County
The median Moultonborough house dates to about 1985, which puts most of the housing stock in the era of Suissevale, Balmoral, and the other lake communities that filled in around the Neck and Route 25. Those houses were built as summer places with a wood stove for October, and a lot of them have since been converted to year-round living by retirees who put in mini-splits under the Co-op’s rebate program. The mini-splits now carry both jobs, cooling through the humid summers and heating through the shoulder seasons, and they were never opened after the install.
What we find inside depends on the room. Living-room mini-splits over a wood stove in a Red Hill or Route 109 farmhouse carry a greasy soot film across the coil that no filter stops. Bedroom mini-splits in the lake communities carry pet hair and the fine dust of a house that gets a lot of traffic in bare feet. Camp mini-splits on Long Island and Kanasatka carry biofilm from a coil that stayed wet from June through Labor Day.
Deep cleaning is the same job for all of them: cover off, bib bag on, coil and blower wheel flushed to clear water, pan and louvers cleaned, everything sanitized, reassembled, and run. On a converted camp with three or four mini-splits we do them all in one visit at the lower additional-mini-split rate, because the load is the same in every room.
Moultonborough Tip
Moultonborough’s converted camps often have the living-room mini-split mounted on the wall above the wood stove flue, where it takes the most soot. If that is your layout, have that mini-split cleaned every spring and the bedroom mini-splits every other year.
The teardown, part by part
The mini-split comes apart in the room it hangs in. After the disconnect is off, the cover, filters, louvers, and drain pan are removed and a bib bag is taped up under the unit to catch everything. The evaporator coil is treated with a foaming cleaner and flushed from the front and, where the chassis allows, from behind, until the fins are bright. The blower wheel is the part that decides whether a cleaning worked: it is scrubbed blade by blade and flushed until nothing more comes off.
The pan is scrubbed and the condensate line is flushed to its outlet. Every surface gets a sanitizing treatment, the parts are washed at the truck, and the mini-split is reassembled and run in cool and heat while we confirm the drain works, the airflow is back, and the temperature split is where a clean unit should be. You pay $199 for the first mini-split and $119 for each one after.
Moultonborough Neck houses run long, so systems here often have two outdoor units: four mini-splits on two compressors is $625. A single unit in a Lees Mills camp is $199. The first is $199 with its compressor, the rest are $119, whatever condition the covers come off in.

Common Questions in Moultonborough
My mini-splits went in under the NHEC rebate a few years ago. Are they due?
Probably. The Co-op has been paying heat pump rebates in Moultonborough for years, and the mini-splits from the early part of that run are now old enough that dust and biofilm have bonded to the coil and wheel. If the mini-split has only ever had its filters rinsed, a deep clean will restore airflow you did not realize you had lost.
Can you do a camp I only reach by boat?
Yes. We ride out with you or meet you at the landing, bring all the gear in one load, and clean every mini-split on the camp in the same trip. It works best combined with your opening or closing run. Tell us the mini-split count and the landing when you book and we will quote it with the trip included.
Does a deep clean fix weak heat in winter?
Often, yes. A blower wheel packed with dust moves less air across the coil, so the mini-split cannot deliver the heat the outdoor unit is producing. If the outdoor unit is also clogged or iced, that needs clearing too. We check both, and if the problem is refrigerant or a failing part rather than dirt, we tell you instead of cleaning it anyway.
