From first question to a cool room

  1. 01

    Tell us what you have

    How many units, and whether it is an HDB flat or a condominium. The office confirms the slot with you.

  2. 02

    We arrive in the slot

    Someone 18 or over needs to be home for the visit. Condo registration is sent ahead, not done on the day.

  3. 03

    The work, and a job sheet

    Each unit is serviced and its readings recorded, so you know what was found and what was done.

  4. 04

    Pay when it is done

    PayNow, bank transfer or cash on the day. Contract customers are invoiced per visit.

No travel charge

Anywhere in mainland Singapore, Sentosa included.

Nothing paid up front

No deposit. PayNow, transfer or cash once the work is done.

You see what we found

Refrigerant pressure is checked and written on the job sheet.
