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.
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.

"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.
