How the team works
Six habits, learned over ten years.
Every habit below comes from what customers describe in their reviews and how the team itself explains the job. Nothing here is a slogan.
Find the root cause
The team always looks for the root cause behind a fault, so the problem gets resolved once and for all, not patched over.
Show you before we start
One customer describes the technicians showing which parts were dirty before cleaning them. Ask the team to walk you through it on the day.
Clean every phase properly
Fan coils, covers, filters and drainage pipes, vacuumed and washed with care at every single phase for lasting effects.
Test cold before leaving
One customer describes the technicians testing the air conditioners after a repair to be sure they were working properly and cold.
Housekeeping as they go
One customer describes the team as self-sufficient, with their own rags, water spray and work mats, and says the toilet they worked in was spotless afterwards.
Advice on maintenance
Reviewers describe being shown how to care for their units, one of them with an economical maintenance schedule to keep up with.

The people behind the mascot
Iskandar and the team.
Dr Cool started out as Dr Cool Aircon Services and has been in the trade for more than 10 years, becoming DR COOL SERVICES PTE LTD along the way. The grinning doctor mascot on the logo carries an SME500 Singapore 2021-2022 badge, and in 2023 alone the team served over 4,000 homes.
The names that come up in the reviews: Mr Iskandar, thanked by name along with his team; technicians Murugan and Deepak, who traced a fault and tested the units until they ran cold; and Renee, who arranged the visit.
The way customers put it: one had the dirty parts shown before they were cleaned, one was taught an economical maintenance schedule, and one found the toilet they had worked in spotless afterwards.
