Best air conditioning contractors in Subang Jaya

★★★★★5 (296 reviews)score 91/100

AC Air Pro tops the list on a near-perfect rating across 296 reviews, the largest and freshest review base of any contractor here. Reviewers describe same-day or next-day visits, full disassembly and chemical wash, and named technicians Abbas and Mudassur who show up on time and clean up after themselves.

• Same-day or next-day booking, often confirmed on WhatsApp within 15 minutes
• Full disassembly and chemical wash rather than a surface wipe
• Named technicians (Abbas, Mudassur) with repeat praise for professionalism
• Pricing described as cheaper than competitors

★★★★★4.9 (89 reviews)score 89/100

Sumon combines an electrical and hardware shop with aircon installation, chemical wash, gas top-up and leakage repair, and it stays open around the clock. With 89 reviews averaging 4.9, customers single out the owner for answering midnight calls and keeping the shop open late for urgent parts.

• Open 24 hours, 7 days a week
• Stocks hard-to-find parts other shops run out of
• Owner personally handles emergency calls and after-hours sales
• Reasonable pricing on both parts and service

Watch out: It's primarily an electrical and hardware trading shop, so aircon work sits alongside a wider retail business rather than being the sole focus.

★★★★★4.8 (465 reviews)score 88/100

Meng has the largest review count on this list at 465, and the pattern is consistent: the owner explains problems patiently, resolves most issues in under 15 minutes, and skips charging for minor fixes. That combination of volume and trust pushes it near the top of the composite score.

• Transparent diagnosis with no hard-selling
• Fast turnaround, often same-day
• Free or no-charge checks on small issues
• Owner personally handles WhatsApp requests

Watch out: Aircon repair is handled alongside car accessories and alarm installation work, so it's not a single-focus aircon outfit.

★★★★★4.7 (171 reviews)score 84/100

Ab Service has over a decade of history and 171 reviews at 4.7, with customers praising units that still run well years later and staff who explain repairs clearly. A couple of recent reviews describe a plumbing fix that failed within a week and chemical damage to furniture during a job, which pulled its sentiment score down from the leaders.

• Fast response and quick job completion
• Strong long-term track record on unit upkeep
• Reasonable, transparent pricing
• Friendly, knowledgeable staff

Watch out: A couple of recent reviews mention a failed follow-up repair and damage to furniture during service.

★★★★★5 (28 reviews)score 80/100

CoolnCool holds a perfect 5.0 rating and reviewers repeatedly name technicians Nasir and Anjum for trustworthy installation and repair work at fair rates. The business is also called out for squeezing in jobs that other contractors can't fit into their schedule.

• Named technicians with repeat praise (Nasir, Anjum)
• Fast turnaround on repair jobs
• Fair, affordable pricing
• Willing to take on jobs others can't schedule

Watch out: The rating is built on 28 reviews, so it's a smaller sample than the contractors above it.

Chandoo pairs aircon installation with electrical wiring work, and its 27 reviews are all five-star. A five-year customer reports zero issues and describes the team as willing to keep working a problem until it's solved.

• Fast response and installation
• Clear communication with no hidden surprises
• Fair pricing on both labour and materials
• Handles aircon and electrical wiring under one job

Watch out: Review volume is modest at 27, so the perfect rating comes from a smaller base than the top few contractors.

★★★★★4.8 (21 reviews)score 74/100

TSEC's 21 reviews run 90% five-star, with customers repeatedly calling out friendly staff and neat, thorough work. One review from about a year ago flagged a specific staff member who didn't return calls, but most feedback since points to solid follow-up.

• Friendly, professional team
• Quick response to bookings
• Neat, thorough finishing on jobs
• Willing to return for follow-up work

Watch out: One older review cited a staff member failing to answer calls and keep promises; review volume is still on the smaller side.

Success Auto is Jason's one-man operation, built on two decades of experience diagnosing car aircon faults without upselling parts customers don't need. It's an official Denso parts reseller, which backs up the technical repairs with genuine components.

• Over two decades of automotive aircon experience
• Honest fault diagnosis, no unnecessary upselling
• Official Denso parts reseller
• Patient, clear explanations of the actual problem

Watch out: Some reviewers find pricing on the higher side, and hidden issues can mean more than one visit.

★★★★★4.8 (13 reviews)score 70/100

MN Cleaning earns strong marks on punctuality and attention to detail for home jobs, with customers noting everything from curtains to mattresses gets tackled without leaving spots behind. It's a smaller operation with only 13 reviews so far, but sentiment is consistently positive.

• Punctual, same-day or rapid response
• Thorough attention to detail
• Transparent, competitive pricing

Watch out: Review volume is limited at 13, and feedback leans toward general home cleaning rather than aircon-specific work.

★★★★★4.5 (8 reviews)score 68/100

Most Max Cooling visits reviewers describe run smoothly, with technicians arriving on time and explaining the work as they go. One customer reported paying RM900 for a chemical wash that wasn't actually performed, then got no response and no receipt, so the small review base (8) carries some real risk alongside the praise.

• Punctual arrival and quick turnaround
• Technicians explain the work during the visit

Watch out: One reviewer reported paying for a chemical wash that wasn't done, with no follow-up response or receipt afterward.

Setia has been operating since 1990 and covers installation, repair, cleaning, ducting and electrical work under one roof across Subang Jaya and wider Selangor. Reviewers call out responsive, professional service, though its 4.3 rating from 52 reviews sits lower than the contractors above it and recent review activity has slowed.

• Established since 1990
• In-house installation, repair and maintenance
• Also handles ducting and electrical work
• Responsive, efficient service

Watch out: Recent review activity has dropped off compared to its overall history, and the rating trails the top-ranked contractors.

ServisYou is certified across Daikin, Panasonic, York and Mitsubishi and publishes standard pricing for cleaning, installation and diagnosis. It has only one review so far, so treat the five-star feedback as a single data point rather than a track record.

• Certified for Daikin, Panasonic, York and Mitsubishi units
• Published pricing for standard services

Watch out: Only one review is on record, so there isn't yet enough evidence to judge consistency.

Hock Huat's 13 reviews are all four or five stars, with Mr. Wong and the team praised for quick arrival, upfront pricing and clear fault diagnosis. It handles general appliance repairs alongside aircon, which is handy if the same visit turns up more than one issue.

• Quick, on-time arrival
• Upfront, fair pricing
• Clear diagnosis and honest advice
• Also covers general appliance faults

Watch out: Review volume is on the smaller side at 13, so the track record is still building.

★★★★☆4 (25 reviews)score 65/100

LKB's team, led by technician Inson, gets praised for full disassembly and chemical wash during routine servicing and installation turnaround of one to two days. Its 4.0 rating from 25 reviews is pulled down by a minority who found pricing steep and one older review that flagged understaffing.

• Full disassembly and chemical wash on servicing
• Fast installation, typically 1-2 days
• Follow-up communication via WhatsApp

Watch out: A minority of reviewers call pricing steep, and one older review mentioned understaffing.

★★★★☆3.9 (9 reviews)score 62/100

Sumber says it has been operating for over 40 years out of Sungai Penaga Industrial Park and runs 7 days a week, but the review evidence is thin and mixed: one reviewer praised the sales service while another reported an order that never arrived. Little of the available feedback speaks directly to aircon work, so treat this as the least-tested entry on the list.

• Claims a 40+ year operating history
• Open 7 days a week

Watch out: One reviewer reported an order that never arrived, and most feedback doesn't address aircon service specifically.
