Enquiries for fixed air conditioning in homes or small commercial premises.

We have spoken to the applicant about the project, timing and agreed criteria. Stated budgets and measurements remain estimates unless specified otherwise.

  • Decision-making authority or permission
  • Fixed installation, not a portable unit
  • Room count and estimated area
  • Installation or replacement identified
  • Project planned within 3 months

These details are the enquirer's own indications and are marked as such in the brief.

  • Number of rooms and estimated area per room
  • Home or small commercial premises
  • Intended use: cooling, heating or both
  • Possible location for the outdoor unit, as described by the applicant
  • Any permission from the owners' association or landlord

What you do not receive

  • Portable air conditioning units
  • Servicing or repair of an existing system only

Service area

You choose postcodes or municipalities. We confirm per region whether enquiries are feasible; without that confirmation we promise no volume or delivery time.

Exclusive, and what that means

Klantwerf supplies the same enquiry to one buyer. The applicant may independently contact other providers.

No. You receive a qualified enquiry. Your business handles the quotation, sale and delivery of the work.

Something wrong with an enquiry?

Report incorrect details, a duplicate or a mismatch with the agreed criteria within 7 calendar days. Valid claims receive a replacement or credit after review. Terms are agreed before you start.

Valid reasons

  • Incorrect or non-existent contact
  • No genuine enquiry
  • Outside the agreed service area or criteria
  • Duplicate Klantwerf enquiry for the same project and the same buyer within 90 days

Not a valid reason

  • The enquirer later changes their mind
  • No contract or sale results from the enquiry

Is the enquirer unreachable after delivery? Report it with a short description of your attempts; we review each case individually. As a guideline: three reasonable attempts over two working days, and never continuing after an objection.

A valid report leads to a replacement or a credit, as agreed in advance. Not both. Media bookings follow their own cancellation terms.

Frequently asked questions

No. We record what the applicant tells us. The technical assessment and any permits remain with you and the applicant.
