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
Technicians show you the dirty parts before any cleaning is agreed. You see exactly what you are paying to fix.
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
Every job ends with the units running and tested, so the air is properly cold before the team packs up.
Leave the place spotless
Own rags, own work mats, own water spray. Customers say the work area was cleaner than they expected when the job was done.
Teach you the schedule
You get honest advice on how to care for your units and an economical maintenance schedule to keep them running.

An air conditioner stopped working on a Friday. The customer called Dr Cool, and Renee arranged for technicians to come the very next morning.
The fix
Murugan traced the fault to the compressor motherboard, replaced it, and tested every unit until the air ran properly cold.
The result
"Our air conditioners are working very well since the repair last Saturday," the customer wrote in his 5 star Google review this April.
