Deep Clean Service

A proper deep clean helps an aircon unit move air as it should, with less smell and less dust blowing back into the room. At Aircon Depot in Clairwood, we clean the indoor coil, filter and blower assembly for homes, offices and small commercial sites across greater eThekwini.

Deep Clean Service

What our deep clean service covers

A deep clean is more than a quick filter rinse. We open the indoor unit and clean the parts that collect dust, mould film and fine build-up over time, especially in Durban’s humid air and in rooms that run daily through summer. This service is suitable for split units, cassette units and other common indoor air-conditioning setups used in homes, shops, clinics and offices.

Our aim is to restore airflow, improve hygiene and help the unit cool with less strain. If the system has a musty smell, weak throw, dusty fins or visible dirt on the blower, a deep clean is usually the right first step before chasing bigger faults.

  • Indoor coil cleaning with suitable detergent and rinse
  • Filter removal, wash and drying
  • Blower fan cleaning to remove dust and slime build-up
  • Drain tray and drain outlet cleaning to help prevent blockages
  • Wipe-down of internal casing and accessible surfaces
  • Basic visual check for leaks, loose wiring and poor operation

How we clean the indoor unit

We start by isolating the unit and protecting the work area. In a home, that may mean covering furniture and flooring. In a shop or office, we keep the area tidy and work around trading hours where we can. Once the cover is removed, the filters are taken out and washed separately. The indoor coil is then treated with the correct cleaning solution so dirt, grease and film lift off without damaging the fins.

The blower wheel gets special attention because this is where a lot of hidden dirt sits. If that part is not cleaned properly, the unit can still smell and the airflow stays poor. We also clean the drain pan and check that water is running out correctly, which matters in humid coastal areas where condensation is heavy.

  • Safe isolation before opening the unit
  • Filter wash and dry
  • Coil wash and rinse through the fin pack
  • Blower wheel cleaning by hand where needed
  • Drain line and tray clearing
  • Reassembly and operation test

Service process, from booking to final test

Once we receive your booking, we confirm the unit type, location and access needs. If the aircon is in a ceiling bulkhead, high wall position or a tight commercial space, we factor in the time and access equipment needed. On the day, our technician inspects the unit first so we can see whether a deep clean is enough or whether there is also a fault that needs attention, such as a blocked drain, weak capacitor or dirty outdoor coil.

After cleaning, we run the system and check for cold air, smooth fan operation and proper drainage. If a deeper issue is found, we explain it plainly and give the next step. We do not rush the job because a half-cleaned indoor unit can still cause smell, low airflow and nuisance dripping. Clear communication matters just as much as the cleaning itself.

  • Booking confirmation and access check
  • On-site inspection before opening the unit
  • Deep clean of indoor components
  • Run test for cooling, noise and drainage
  • Feedback on any extra repair needed

Turnaround times for Durban homes and businesses

Most standard deep cleans on a single domestic split unit can be completed the same day, often within 1 to 2 hours depending on dirt build-up and access. Larger cassette units, multiple rooms or units mounted high may take longer. For commercial sites in Durban Central, South Durban or along busy routes in West Durban, we can schedule work around trading, office hours or staff movement to keep disruption low.

If a unit is badly clogged, has heavy mould film or has not been serviced in years, the cleaning time increases. A drain issue or access problem can also add time. We would rather do the job properly than leave dirt behind, because the benefits are lost fast if the blower and coil are not fully cleaned.

Pricing approach and what affects the cost

Our pricing is based on the unit type, number of units, height, access and the amount of cleaning needed. A simple wall-mounted bedroom unit costs less to service than a ceiling cassette in a busy office or a unit that needs careful strip-down. If the drain is blocked, the filters are damaged or the blower needs extra manual cleaning, we explain that before we continue.

We quote fairly and keep it practical. For larger sites in Clairwood, Durban Central or greater eThekwini, we can often price a planned deep clean programme for several units at once, which helps reduce downtime and avoids emergency call-outs later. If a unit has ongoing smell or poor cooling, a deep clean is usually a better spend than repeated top-up visits that only give short relief.

  • Unit size and type
  • Installation height and access
  • Number of indoor units on site
  • Condition of filters, coil and blower
  • Need for after-hours or scheduled commercial work

How often to book a deep clean

For most homes in Durban, a deep clean every 12 months is a sensible starting point. If you run the aircon daily, live near the coast, keep windows open often, or have pets and high dust levels, every 6 to 9 months may be better. In offices, salons, clinics and small retail spaces, regular use and more people moving through the area usually means the indoor coil and blower collect dirt faster.

Frequent filter washing helps, but it does not replace a proper internal clean. If the unit has lost airflow, starts smelling damp or leaves dust on furniture, it is already overdue. Coastal humidity can make this worse because moisture helps dust stick to the coil and blower blades. Regular maintenance keeps the indoor unit healthier and easier to service later.

When a deep clean is the right choice

This service is a good fit when the unit still works but the comfort level has dropped. If the room takes longer to cool, the fan sounds strained, or there is a stale smell at switch-on, the issue is often inside the indoor unit and not only in the gas or compressor. A deep clean can also help after a long summer, after renovations, or when a property has been empty and the unit gathered dust.

Aircon Depot works from Clairwood and serves Durban Central, South Durban, North Durban, West Durban and the wider eThekwini area. Our team handles homes and business sites with the same practical approach, and we can combine deep clean service with fault finding or planned maintenance where needed. If you want better airflow and a cleaner indoor unit, this is the service to book.

What clients say

Questions we get asked

Will a deep clean fix weak cooling?

If weak cooling is caused by dirt on the indoor coil or blower, a deep clean can improve airflow and comfort. If the problem is gas loss, a faulty fan motor or a compressor issue, we will flag that after inspection.

Do you need to remove the aircon from the wall?

Usually no. Most deep cleans are done on site with the unit still installed. We open the indoor section, clean the internal components and test the unit again once it is reassembled.

Can you service more than one unit in the same visit?

Yes. We often clean several units in one booking for homes, offices and small commercial sites. That helps save time and makes maintenance easier to plan.
