Mini-Split Deep Cleaning in Franklin
Electric utility: Eversource · Merrimack County
Walk any of the streets above the falls in Franklin and you are looking at houses from the mill years: two-story cottages, Victorians with tall windows, and the triple-deckers and duplexes that housed the hosiery workers. When oil got expensive, a lot of these got mini-splits, sometimes one mini-split per floor. They run most of the year in houses that leak heat, and the blower wheel collects a mix of dust, cooking residue, pet hair and, where there is a pellet stove, a fine ash that bonds to the wet fins. Airflow drops a little each year until the mini-split is loud and the room is never quite right.
Up at Webster Lake the problem is different. The camps and year-round homes around Griffin Beach and the city beaches run their mini-splits hard through humid summers, and the seasonal ones go dark in October with a wet coil. A first deep clean on a Webster Lake mini-split usually reveals a blower wheel that has never been touched since the Eversource NHSaves rebate paid for the install.
Franklin sits where two rivers meet, and downtown holds August humidity like a bowl. The old stone and brick basements are damp all year, so the coils in ground-floor rooms rarely dry. That is why a Franklin mini-split loads faster than one on a hill in Sanbornton, and why the first cleaning is the dirtiest one.
Franklin Tip
Franklin houses that run a pellet stove in the same room as the mini-split should have the mini-split deep cleaned in April, once the stove is cold, so a winter of ash is out of the blower wheel before the mini-split starts pulling humid river air across it.
A deep clean, done in place, on a Franklin wall unit
Nothing comes off the wall. The louvers, cover and filters are removed, a bib bag is hung under the mini-split to protect the floor of a Central Street apartment or a camp on Webster Lake, and the coil gets a foaming cleaner worked into the fins. While it works, the blower wheel is scrubbed blade by blade and flushed from both sides. On a Franklin mini-split that has run beside a pellet stove, that wheel is where the time goes, and it is the reason the airflow comes back so dramatically afterward.
The coil is flushed at low pressure until the rinse runs clear, the drain pan is scrubbed to bare plastic and the condensate line is flushed so the pan empties completely. Every wet surface is sanitized, the louvers and cover are washed and dried, and the mini-split is reassembled and run in cool and heat while we check airflow, temperature change and that the drain is dripping outside. The first unit carries the trip at $199; the rest are $119 each.
A Franklin mill-era three-decker with three mini-splits on one compressor is $437. A Webster Lake camp with a single unit is $199. The first is $199 with the compressor and the rest are $119, so a century of horsehair-plaster dust costs the same as a new-build install.

Common Questions in Franklin
How do I know my Franklin mini-split needs a deep clean and not just new filters?
Weak airflow with clean filters is the tell. If the mini-split is louder than it was, the air feels thin even on high fan, or there is a stale smell, the loading is on the blower wheel and coil behind the filters. A flashlight up through the louvers will show a grey, fuzzy wheel.
Does a deep clean help with the Eversource bill in an old Franklin house?
Yes, when the mini-split is doing real heating. A loaded blower wheel and insulated coil cut airflow and output, so the compressor runs longer to do the same job. In a drafty 1910 cottage that heats with the mini-split most of the winter, restoring the airflow is a measurable difference.
Can you clean a mini-split in an occupied apartment?
Yes. The work is contained to the bag under the mini-split and a bucket, the parts are washed in a sink or outside, and the tenant can stay. Landlords in Franklin's multi-family buildings usually have us do every unit on one visit with a record per apartment.
