Seasonal Mini-Split Maintenance in Franklin
Electric utility: Eversource · Merrimack County
Franklin houses run mini-splits as heat, so fall comes first. The workers' cottages and multi-families downtown and the farmhouses out toward the Franklin Falls Dam and Flaghole Road lose heat fast in January, and a mini-split with dirty filters and an iced-up condenser cannot keep up. Before the stove season we wash the filters, clear and level the outdoor unit so ice and snowmelt drain out of the base, check the defrost behavior and run the mini-split in heat with temperature readings. In a house that heats with the mini-split most of the winter, that visit shows up on the Eversource bill.
Spring is for pollen and drainage. Condensers near Webster Lake, along the river trails and under the trees on the older streets are matted by late May. We rinse them from the inside out, wash the filters again, give the indoor coil a light rinse and flush the condensate line so the mini-split goes into the humid months moving air and draining water. Camps at Webster Lake that close for winter need only this visit, at opening.
Where a pellet stove shares a room with the mini-split, spring includes a close look at the fins for ash, and if the blower wheel is already grey we recommend the deep clean instead of pretending a tune-up will do.
Franklin Tip
Franklin condensers on the low streets near the river collect ice in the base by December; a fall visit that levels the unit and confirms the base drains is the cheapest way to avoid a frozen fan in a cold snap.
The fall visit and the spring visit, item by item
Fall: filters washed, coil checked for early loading, remote and settings checked so the mini-split is not stuck in a wasteful mode, outdoor unit cleared of leaves and leveled, condenser base checked for drainage, and a heat run with temperature readings. Fan wobble, ice starting in the base or a defrost that is not cycling get fixed in October, not January. About thirty minutes per mini-split.
Spring: outdoor coil rinsed clear of pollen and grit, base cleared, clearance checked. Indoors, filters washed, coil lightly rinsed, condensate line flushed and the pan checked for standing water, then a cool run to confirm the temperature drop and that the drain is dripping outside. Mini-Splits that share a room with a pellet or wood stove get the fins inspected for ash, and anything that has gone past tune-up territory is flagged for a deep clean rather than glossed over. The annual plan puts both visits on one rate.
Spring and fall visits to a two-mini-split Franklin house are $318 each — $199 for the first with its compressor, $119 for the second. Booking the plan is about getting a date before the river valley humidity, not about paying less.

Common Questions in Franklin
When should a Webster Lake camp get its spring tune-up?
At opening, usually Memorial Day week or the week before, after the pollen has mostly dropped. That single spring visit washes filters, rinses the coils, flushes the drain and clears the condenser, which is all a seasonal camp needs. A camp that closes in October does not need the fall visit.
Is a fall tune-up really necessary if the mini-split worked fine last winter?
For a Franklin house that heats with the mini-split, yes. The fall visit is what catches dirty filters, an iced condenser base and a defrost that is not cycling before the cold weather exposes them. A mini-split that worked fine last January has one more year of loading on it now.
What if a tune-up is not enough for my mini-split?
We tell you on the spot. A tune-up covers filters, a light coil rinse, a drain flush and a condenser rinse. If the blower wheel is already packed with dust or ash, that needs a teardown, and we recommend the deep clean rather than doing a tune-up that will not fix it.
