Seasonal Mini-Split Maintenance in Campton
Electric utility: NH Electric Co-op and Eversource (split territory) · Grafton County
Electric baseboard was the default heat in the seventies chalets up at the Estates and in a fair number of the split-levels around the Lower Village. Median house in Campton was built in 1985. Those owners got the biggest rebate on the books — two thousand dollars a ton when a heat pump takes over eighty percent of the load from resistance heat — and the installers hung two, three, four mini-splits on a single compressor to hit the number. Good installs, mostly. But a house that was heating with baseboard has no ductwork and no filter anywhere; the mini-split is now the only thing in the house that moves and filters air, and it’s doing it on a wheel the size of a rolling pin.
The 183 mobile homes along Route 175 and elsewhere in town are the other big rebate crowd. A single mini-split in a mobile home does the whole place, runs nearly nonstop from November to March, and sits low to the floor where the dog hair is. Those units come in the dirtiest of any we see for the hours on them, and they’re also the ones the owner can least afford to replace at year eight because nobody ever cleaned the coil.
Then the year-round oil and propane houses that added a mini-split for summer and shoulder-season heat through Campton Community Power’s supply rate, and the Beebe River and Hollow places where the heat pump backs up a stove. Different install, same maintenance: the coil gets dirty at the speed the house makes dust, and the compressor gets dirty at the speed the trees drop on it.
Campton Tip
If your mini-split replaced electric baseboard on a rebate, put a yearly reminder on the calendar for the week the snow leaves the compressor. Those units earn their keep all winter and have no other heat behind them.
What a maintenance visit covers
Same take-apart as a deep clean, because that’s the only kind that does anything. Cover off, filters, louvers, pan. Coil cleaned and rinsed. Blower wheel scrubbed. Pan and drain line cleared. Then the part that’s actually maintenance: we check the drain runs downhill the whole way and isn’t sagging behind the unit, look at the line-set insulation where it leaves the wall (UV and squirrels eat it), check the condensate pump if there is one, and make sure the mini-split is still level on its bracket. A unit that tips a quarter inch toward the wrong corner overflows the pan onto your drywall.
Outside, the compressor coil gets rinsed and the base cleared. We check the pad or bracket, the disconnect, and that snow won’t bury the bottom coil in a normal winter. If it’s sitting in a drift line under the eaves we’ll say so. We don’t open the refrigerant circuit; if the unit needs a charge, that’s an HVAC tech with gauges, and we’ll tell you honestly rather than guess.
Once a year for a mini-split that’s the main heat, every two for a summer-and-shoulder unit. Wood houses and mobile homes: every year, no exceptions.
First indoor mini-split with its outdoor compressor is $199. Each additional indoor mini-split is $119; each additional outdoor compressor is $69. A single-zone in a Route 175 mobile home: $199. Four mini-splits on two compressors in an Estates baseboard conversion: $625. Maintenance and deep clean are the same visit at the same price. There’s no lighter version.

Common Questions in Campton
Does cleaning affect my NHEC or Eversource rebate or the warranty?
It doesn’t touch the rebate; that was paid on the install. Most manufacturer warranties expect the unit to be maintained and a clogged coil is exactly the kind of thing they’ll point to if a compressor fails early. We leave a dated record of the visit. Keep it with the rebate paperwork.
How much efficiency does a dirty mini-split actually lose?
Enough to notice on the bill. A coil and wheel carrying two winters of dust move less air and the unit runs longer cycles to hit the setpoint. On a baseboard-conversion house where the heat pump is the whole heating system, a couple of hundred dollars a winter isn’t unusual. That’s the $199 back in one season.
My installer said just rinse the filters monthly. Isn’t that enough?
Do the filters, absolutely. But the filter screen is coarse, and fine dust, soot, and pollen go straight through it onto the coil and wheel. Filters are the part you can reach. We do the part you can’t. Both matter.
Can you service a mobile-home unit that’s mounted low?
Yes, and they need it more than most. Low units pull in floor dust and pet hair, and the drain line often runs through the floor and freezes at the skirting in January. We check that run every time. If the skirting needs a gap or the line needs heat tape, we’ll show you.
Do you do the compressor up at the Estates in winter?
We can, but spring or fall is better. In winter the compressor coil is frosted half the day and there’s nothing to see. Book once the snow is off the base and we’ll clear a season’s worth of needles and check nothing got crushed by the roof slide.
