AC Cleaning After Renovation: Removing Construction Dust Before Moving In

After renovation work, AC filters and cooling coils accumulate heavy dust and debris. Arrange a deep clean before moving in to protect the units and restore normal airflow.

When this service is suitable

Sawing, sanding and plastering during renovation send dust into AC units, blocking filters and cooling coils and reducing efficiency. Post-renovation cleaning is best done before furniture arrives, giving the technician clear access. If damage from the renovation is found, repair is a separate inspection-first, quote-after service.

  • Renovation dust left uncleaned accelerates wear on AC components over time
  • Cleaning before furniture arrives gives the technician easier access and better site protection
  • Any faults found during cleaning are reported honestly and not added to the scope without confirmation

The Right Time to Clean After Renovation

The best window is after completion and before furniture moves in.

  • Book after renovation is complete and before furniture is brought in
  • Tell the technician the type of work done (e.g. sanding, concrete) to help assess dust levels
  • Confirm the power supply and drainage are functioning for the post-clean test
  • Cleaning multiple units together follows a decreasing per-unit schedule

What the Clean Covers

The standard deep clean covers the items below; steam is an optional add-on.

  • Pre-clean power-on test to understand current condition
  • Removal and washing of filters, fan blades and covers (clearing construction dust)
  • Deep cleaning of the cooling coil to remove dust build-up
  • High-pressure flush of the drain pipe
  • Reassembly and post-clean function test

Repair and Installation Are Separate

Damage from renovation is outside the scope of cleaning and will be reported.

  • Damage to components or electrical issues from the renovation are reported by the technician if found
  • Repair is a separate inspection-first, quote-after service
  • Installing a new unit is a separately quoted installation service
  • Cleaning includes a 90-day drip and leak follow-up (covering issues caused by the cleaning only)

Price and quote factors

  • Number of units: multi-unit cleaning follows a decreasing per-unit schedule
  • Level of dust: type and duration of renovation affects build-up; the technician explains what to expect
  • Add-ons: Kärcher high-temperature steam is optional and can remove heavier construction dust

Frequently asked questions

Is post-renovation AC cleaning really necessary?

It is strongly recommended. Construction dust in the cooling coil reduces performance in the short term and accelerates component wear over time. Cleaning promptly after renovation prevents these problems.

The dust is very heavy — is a basic clean enough?

In most cases the standard deep clean is sufficient. If build-up is particularly heavy the technician explains what to expect before starting and can recommend adding the steam option if needed.

Could there be renovation damage that needs repair?

Cleaning removes surface build-up but cannot fix damaged components. The technician will flag any damage noticed during cleaning and a separate inspection and quote can be arranged.
