Air conditioner cleaning in Longueuil and on the South Shore

Running a vacuum over the filter is not cleaning an air conditioner. The coil, the blower wheel and the drain get fouled where you never look - and that is what causes the smell, strains the compressor and drives up your bill. We take the unit apart and clean everything with pressurized water, with before and after photos and the exact price given up front.

We take the unit apart

Wall-mounted or central, we open the machine and clean the coil, the blower wheel and the drain. Not just a pass with a vacuum over the filter.

Before and after photos

The inside of the unit before, the result after. You see what was hiding in there.

In-house team

You follow the technician from one end of the work to the other. Never a subcontractor, on principle.

What makes your air conditioner smell bad

Your air conditioner, wall-mounted or central, passes the air of the house over a cold coil to cool it down. That air carries dust, and the coil stays permanently damp while the unit runs. Dust plus moisture, on a dark enclosed surface: that is exactly what mould needs to take hold. That is where the stale smell comes from, the one that returns every time you turn the air conditioner on.

The coil (the evaporator) loads up with grime, the blower wheel (the fan pushing the air) gets fouled, and the condensation pan and drain accumulate standing water and deposits. The filter only catches the coarse dust at the surface - everything else passes through and lodges in the parts you cannot reach without taking the unit apart.

And it is not just a question of smell. A fouled air conditioner strains to do the same job: a dirty coil insulates poorly, the air circulates less, the compressor runs longer and harder. The result: a rising bill, a unit wearing out prematurely, and eventually a compressor that gives out.

Air conditioner cleaning means taking the unit apart and cleaning it thoroughly, not just rinsing a filter. It is a service from the ventilation cleaning silo, done by the same in-house team, with before and after photos and the exact price given up front.

How we clean your air conditioner

We take it apart, we protect the area, we clean with pressurized water and a soap that is safe for the machine, we put it back together. Here is how it happens.

1. We take the unit apart

Wall-mounted or central, we open the machine to reach the coil, the blower wheel and the drain - the parts surface maintenance never touches.

2. We protect the surroundings

We fit a cleaning bag to channel the water and protect your wall, your floor and your furniture. Nothing spills into the room.

3. Pressurized water cleaning

We clean the coil, the blower wheel and the pan with pressurized water and an approved soap, safe for the machine. That is what gets the mould and the odours out.

4. We reassemble and photograph

We put the unit back together, check that it blows properly, and deliver your before and after photos of the inside.

"I run the vacuum over the filter, that is good enough"

Rinsing the filter is a good habit, but it only touches the first barrier. The dust that matters, the kind that has stuck to the damp coil and feeds the mould, is inside the unit. To reach it, you have to take the machine apart and clean under pressure - a surface vacuum does not even come close.

The other idea is "my air conditioner still cools, so it must be fine." The problem is that a fouled unit does still cool - but by straining. You do not notice the difference in comfort right away, you notice it on the bill and on the day the compressor gives out. An air conditioner that has never been cleaned means a compressor straining for years until it eventually blows.

And that is where the math gets serious: if parts for your model are no longer made, a dead compressor often means replacing the whole unit. Cleaning is what protects your investment. If your air conditioner already has a mechanical problem, cleaning is not what it needs, and we also do air conditioner repair with the same team.

Frequently asked questions about air conditioner cleaning

A good benchmark is one complete cleaning per year, ideally in spring before the cooling season, with a filter rinse partway through the summer. If you have pets, allergies in the house, or if the unit smells stale when it starts, aim for more often. The filter itself should be rinsed every few weeks during the season - but that does not replace a thorough cleaning of the unit.
It is almost always mould. The coil stays damp while the unit runs, dust sticks to it, and on that dark enclosed surface mould takes hold. Every time you start the air conditioner, it blows air through that - and that is the stale smell you notice. Rinsing the filter changes nothing because the source is further in, on the coil and in the pan. A thorough cleaning removes the mould at the source, and the smell goes with it.
The filter is the first barrier: rinsing it removes the coarse surface dust, and that is good basic maintenance. A professional cleaning means taking the unit apart to reach the coil, the blower wheel and the drain - the parts where grime and mould actually accumulate and that no surface maintenance touches. We clean these components with pressurized water and a soap that is safe for the machine, with before and after photos of the inside.
Yes, because a clean air conditioner works less hard for the same result. A fouled coil insulates poorly and blocks airflow, so the unit runs longer and the compressor strains harder to cool the room. By cleaning the coil and the blower wheel, you give the unit its capacity back, it reaches the target temperature faster and shuts off sooner. The benefit shows up on the bill, and above all in the lifespan of the compressor.
Spring, before the first heat wave. It is the ideal moment because the unit has sat idle all winter and you want to start the season on a clean machine, without the stale smell of that first startup. Doing the cleaning before you really need it also avoids ending up without cooling in the middle of the heat. If you only think of it in summer, it is still worth doing - but the spring prep ritual is the better habit.

(Translated by Google) We live in a condominium and suspected that one of the owners had a bird's nest in her dryer vent. Pierre-Alexandre came and did a thorough cleaning and was very respectful of nature, placing the three eggs he found under our cedar trees, along with part of the nest removed, in case the mother returned for her chicks. He did an excellent job working at heights (3rd floor) and we will definitely contact this company again if needed. Thank you, Pierre-Alexandre!

Nous sommes en copropriété et nous nous doutions qu'une des copropriétaires avait un nid d'oiseau dans son conduit de sécheuse. Pierre-Alexandre est venu faire un bon nettoyage et a été assez respectueux de la nature pour poser sous nos cèdres les 3 oeufs trouvés avec une partie du nid enlevé au cas où la mère reviendrait pour ses petits. Il a fait un excellent travail en hauteur (3e étage) et nous recontacterons assurément cette compagnie au besoin. Merci Pierre-Alexandre
