How a visit works

How many units, and whether it is an HDB flat or a condominium. The office confirms the slot with you.
Someone 18 or over needs to be home for the visit. Condo registration is sent ahead, not done on the day.
Each unit is serviced and its readings recorded, so you know what was found and what was 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.

Same fault back within 14 days and we return at no charge.
