Airflow restored
A cleaned coil and blower wheel move the air the unit was designed to move.
Service
Air conditioner deep cleaning
A fouled coil makes your air conditioner work harder, cool less and smell worse. A proper deep clean is the cheapest performance improvement available to any AC unit.
What dirt actually does to an air conditioner
An air conditioner works by moving heat across two coils. Both of them need air flowing freely through their fins to do that. Dust, grease and microbial growth build up on the indoor evaporator, while sand and airborne debris block the outdoor condenser.
As the fins clog, airflow drops. The compressor runs longer to reach the same temperature, running current stays high for more of the day, and the coil can drop cold enough to ice over — at which point the unit stops cooling entirely. The same damp, dirty evaporator surface is what produces the sour smell that appears when the unit starts.
A wash-down of the filters helps, but it does not reach the coil surfaces, the blower wheel or the drain pan. Those need the unit opened up and cleaned properly.
The difference a deep clean makes
The fins on the left are what a coil looks like after two seasons without cleaning. Airflow through that is a fraction of what the unit was designed to move.
What a deep clean covers
-
Filters
Removed, washed, dried and refitted — or replaced if they are beyond cleaning.
-
Evaporator coil
The indoor coil is protected, treated and washed so the fins are clear across their full depth, not just on the visible face.
-
Blower wheel
The rotating drum behind the coil accumulates a hard layer of dust that badly cuts airflow and is invisible without opening the unit. It gets cleaned properly.
-
Drain pan and drain line
Cleared and flushed, and the fall on the drain line checked, so condensate leaves the unit instead of overflowing into your room.
-
Condenser coil
The outdoor coil is washed out from the inside so debris is pushed back out of the fins rather than deeper into them.
-
Running check
Airflow, drainage and cooling verified before we leave.
What you get back
Lower running cost
The compressor reaches the set temperature sooner and spends less of the day running.
The smell gone
Removing the growth on the coil and in the drain pan removes the cause, not the symptom.
Fewer breakdowns
Most icing and drainage callouts trace back to fouling that a clean would have prevented.
Cleaning questions
How often should a split AC be cleaned?
A full deep clean once a year before the cooling season suits most homes. Twice a year in dusty areas, near building work, in kitchens, or for units running long commercial hours. Filters should be rinsed by the user every two to four weeks during heavy use.
How long does a deep clean take?
Usually one to two hours per split unit, depending on how fouled it is and whether the indoor unit has to be removed from the wall for a full-strip clean.
Will cleaning fix my weak cooling?
If the cause is a clogged coil or filter, yes — often dramatically. If the cause is low refrigerant, a failing compressor or an electrical fault, cleaning will not fix it. We check while we are there and tell you which it is.
Do you clean units you did not supply?
Yes — any brand and any type, including cassettes, ducted systems, air handling units and fan coil networks, not only wall splits.
