What recent reviews say

Staff answer questions fast and thoroughly: Hao Jun, Marcus, and Cindy are named for prompt replies and clear communication. Technicians Raf, Rafiq, Iqbal, and Mahid carry out work that is detailed and thorough. Customers who have used them for 20+ years consistently praise consistency. They also chase issues (returning same-day to fix leaks) and follow up by phone a week later.

The company charges transparent prices without pushing unnecessary add-ons. Installations and servicing both receive praise for quality, though one 2022 installation fell short. They clean thoroughly after work, disassemble blowers for deep cleaning, and explain what they are doing step-by-step. Many customers discovered them via Reddit recommendations.

Caredy Air-conditioning & Electrical Services

5.0(110)✓ Google-verified

Five-star reviews consistently highlight Caredy's refusal to oversell. Technicians diagnose honestly, explain work upfront, and refuse unnecessary upsells, a stark contrast reviewers noted against other companies. Punctuality and speed are reliable; teams arrive on time, complete jobs efficiently, and protect surroundings with plastic sheeting. Jin and Tan are named technicians who handle jobs with care. Appointment booking is simple via WhatsApp, confirmations come within a day, and teams communicate proactively about delays. One reviewer's PCB repair required two trips for exact parts; Caredy adjusted charges to match actual work. Cleanliness after work and maintenance tips are consistent touches.
