Ductless Heat Pump Maintenance, Done at Every Head

In a ductless system, the filter screens, the coil and the blower all sit inside the head on your wall, rather than in one central box the way a standard air conditioner installation does. So we service each head by hand, one room at a time.

We wash the screens, clean the blower wheel and the coil behind it, flush the condensate drain, and check the charge at both ends of your mini split.

A ductless head that has been cleaned properly smells fresh, moves air the way it did when it was new, and keeps the wall beneath it dry.

What We Do on a Ductless Mini Split Maintenance Visit

Both ends of the system get serviced, and every head in the house gets the same attention.

We wash the filter screens

The screens in your ductless head are reusable, so we take them out, wash them and refit them, and your airflow comes straight back.

We clean the blower wheel

We lift the shroud and clean the wheel itself, which is the part that holds damp dust and gives a head that musty start-up smell.

We deep clean the indoor coil

The coil sits a few inches from the air you breathe, so we clean it back to bare fin and restore full heating and cooling.

We flush the condensate drain

We flush the drain line, check the pan and confirm it runs clear, so the wall under your head stays dry in humid weather.

We clear the outdoor unit

We wash the outdoor coil, check the fan and inspect the line-set insulation, because both ends of the system share the same workload.

We verify the refrigerant charge

We measure the charge and check the flare connections, so a slow leak turns up here and not in July.

We check the electrical connections

We inspect the disconnect, tighten the terminals and measure the draw on the compressor and fans, where a tired part usually shows itself first.

We test every zone before we leave

We run each head on its own controller in heating and in cooling, so you know the whole system works, not just your main room.

Keeping Your Mini Split Healthy Between Visits

Rinsing the screens once a month keeps your airflow strong, and it is easy to do. The blower wheel and the coil behind it need tools and a shroud removal, so we handle those.

Book a mini split maintenance visit once a year, or twice if your system heats as well as cools, because it works right through both seasons. Each head is serviced on its own, so a four-zone home takes longer than a single wall unit.

What you can do What we do on the visit
Rinse the washable screens once a month We clean the blower wheel behind the shroud
Wipe down the front panel We deep clean the coil face
Keep leaves and snow off the outdoor unit We flush the drain and check the pan
Tell us about a smell or soft airflow We check the charge and the flare joints
Run each head in the shoulder season We test every zone and report back

If your system has stopped altogether, that is a ductless mini split repair rather than maintenance, and we will say so on the phone. If your home has ductwork, heat pump installation is the better conversation.

How a Mini Split Maintenance Visit Runs

A ductless mini split maintenance visit follows the same order every time, and you will know what we found before we leave.

1

Tell us about your system

Call or message us with how many heads you have and whether the system heats as well as cools, and we will book enough time.

2

We run it before we touch it

We start every zone and note how each one is performing, so there is an honest starting point to measure against.

3

We clean at both ends

We work through the screens, coil and blower wheel at every indoor head, then move outside to the condenser coil and the line-set connections.

4

We test and tell you what we found

Every zone runs in both modes before we pack up, and you get a plain account of what we cleaned and what to watch.

Where we service ductless mini splits

We serve across the Kitchener-Waterloo Region and into Wellington, Perth and Oxford counties, and a multi-head system takes longer than one wall unit, so we book the time before we set out. Call and ask about your town, because our ductless mini split maintenance may already reach it.
