Ranked picks

PJ Aircon service
score 90/100Why it ranks first
PJ Aircon scores 89.9 with a perfect 5.0 from 209 reviews and high confidence. Named technicians Ismail and Muhammad earn consistent praise for leak diagnosis, thorough post-service cleaning, and reasonable pricing. One damaging complaint alleges a misdiagnosed compressor fault later corrected by the manufacturer's centre, so it is worth getting a second opinion on any major part replacement.
Pros
- Leak diagnosis and repair cited across multiple reviews
- Thorough post-service cleaning, including surrounding areas
- Named technicians with consistent track records
- Responsive to urgent bookings
Watch-out:One reviewer reports a misdiagnosed compressor issue and upselling of unneeded parts, later corrected by the manufacturer's centre.

MK Aircon service
score 93/100Why it ranks second
MK Aircon tops the confidence-adjusted rankings with a composite score of 92.9. Across 252 reviews, customers consistently flag the team's site protection (tarps and drop frames), honest assessments that avoid unnecessary charges, and flexible same-day scheduling. The one recurring note is an occasional dip in cooling performance days after a service, so it is worth confirming the job scope before they leave.
Pros
- Meticulous worksite protection with tarps and drop frames
- Honest diagnosis: customers report being talked out of unnecessary parts
- Same-day and flexible scheduling
- Fair, transparent pricing across installation, repair, and gas top-ups
Watch-out:A small number of reviewers noticed cooling performance drop within days of a service, suggesting thoroughness can vary by technician.

Frost Aircond Services
score 92/100Why it ranks third
Frost Aircond scores 91.5 with high confidence across 125 reviews, the cleanest sentiment profile in the top three. Customers in PJ and KL highlight transparent cost breakdowns, detailed drain-pipe and cabling checks, and a 24-hour emergency turnaround. No significant complaints appear in recent reviews, which is a meaningful signal given the volume.
Pros
- Emergency response within 24 hours
- Detailed inspection covering drain pipes and cabling, not just the unit itself
- Transparent pricing with a clear cost breakdown before work starts
- Clean worksite practices consistently mentioned across reviews

Mr Problem (Petaling Jaya HQ)
score 91/100Why it ranks fourth
Mr Problem's Petaling Jaya HQ scores 90.8 with 324 reviews behind it. Hassan is named repeatedly for knowing exactly what is wrong and explaining it plainly, and customers report clean, repeat-worthy workmanship. The 4.8 Google rating is the first sign of any friction, but sentiment analysis reads strongly positive overall.
Pros
- Technician Hassan praised by name for technical depth and courteous manner
- Fast, same-day attendance
- Clear fault explanation before and after the job
- Clean, reliable workmanship that brings repeat customers

Kelana Jaya aircon service
score 89/100Why it ranks fifth
Kelana Jaya aircon scores 89.4 with the highest review volume in this list at 398 ratings. The team can knock out four units in two hours, and several customers mention relationships spanning years. Diagnostic consistency and pricing clarity have drawn occasional criticism, so confirm the quote before work begins.
Pros
- Largest review base in this list, with sustained recent activity
- High-volume efficiency: four units completed in two hours noted by reviewers
- Long-standing repeat customers across years
- Can travel outside the Klang Valley for larger jobs
Watch-out:Pricing should be confirmed upfront, and a few reviewers noted variable troubleshooting quality across different technicians.

Madyha Construction
score 84/100Why it ranks sixth
Madyha Construction scores 84.1 with 60 reviews and genuinely round-the-clock availability, with reviewers specifically mentioning midnight and public-holiday call-outs completed without delay. Named technicians Imran and Hannan appear repeatedly. The relatively smaller review base keeps this at #6 rather than higher, but the sentiment is strongly positive.
Pros
- Verified midnight and holiday call-outs completed on the day
- Named technicians Imran and Hannan cited for consistent professionalism
- Transparent pricing with no upselling
- Same-day booking and job completion across PJ and Selangor

Aircond Care Service
score 83/100Why it ranks seventh
Aircond Care scores 82.6 across 32 reviews, with customers reporting repairs completed in as little as 45 minutes and installations done the same day. The team led by Imran is noted for friendly communication and no hidden charges. The review count is on the lower side, which tempers confidence slightly.
Pros
- Repairs completed in as little as 45 minutes
- Transparent pricing with no upsells
- Chemical cleaning and full installation in scope
- Friendly, repeat-business-generating communication style
Services:aircon installation, aircon servicing, aircon repair, central vrv vrf

Selangor aircon service
score 82/100Why it ranks eighth
Selangor aircon service scores 82.4 with 30 reviews and a medium confidence rating. Customers highlight on-schedule arrivals, quick diagnosis, and reasonable rates with no hidden costs. The smaller review pool means the picture is positive but not yet fully tested at scale.
Pros
- Consistent on-time arrival flagged across reviews
- Quick diagnosis and job completion
- Transparent pricing with no hidden costs
- Personable technicians generating repeat bookings and word-of-mouth
Watch-out:With only 30 reviews, confidence is medium, so the track record is promising but limited.

ERZ Teguh Aircond Service
score 83/100Why it ranks ninth
ERZ Teguh scores 83.2 backed by 302 reviews, and technicians Syamil and Afiq earn genuine praise for fast turnarounds and fair rates. The mixed sentiment flag is real, though: no-shows and ghosting after rescheduling appear in recent complaints, creating a notable gap between their best and worst visits.
Pros
- Same-day appointment availability with a large, experienced crew
- Competitive pricing against market rates, confirmed by multiple reviewers
- Complete service scope: repairs, gas refills, installations
- Technicians Syamil and Afiq specifically praised for professionalism
Watch-out:Recent reviews flag no-shows and ghosting after rescheduling, with some jobs leaving screws, trash, and tape behind.

AISY AIRCOND SERVICES PETALING JAYA
score 82/100Why it ranks tenth
AISY AIRCOND scores 82.4 across 56 reviews, with strong marks for punctuality, efficient job completion, and thorough unit cleaning. One significant complaint around warranty accountability and upselling of chemical cleaning after a faulty installation keeps it out of the top tier, but day-to-day maintenance work draws consistent praise.
Pros
- Consistent early or on-time arrival
- Thorough unit cleaning cited across multiple reviews
- Friendly, clear communication from technicians
- Honest pricing on standard servicing jobs
Watch-out:One reviewer reports a warranty dispute after an installation fault, with pressure to pay for chemical cleaning instead of a fix, raising accountability concerns.

Frostcool Solutions - Aircond Service & Repair
score 81/100Why it ranks #11
Frostcool Solutions scores 80.8 with the strongest individual sentiment score in the lower half of this list (0.83). Customers specifically note that technicians recommend only what is actually needed, arrive early, and leave the site clean. The 23-review count keeps confidence at medium, so treat it as a strong early signal rather than a fully established track record.
Pros
- Technicians advise only on genuinely needed services, no upselling
- Often arrive ahead of schedule
- Clean, tidy workmanship consistently noted
- Fair, transparent pricing
Watch-out:Only 23 reviews to date, so confidence is medium and the sample is still limited.

Aircon Champions Sdn Bhd
score 76/100Why it ranks #12
Aircon Champions scores 75.8 with a medium confidence rating across 14 reviews. Customers single out Mr Ali for thorough compressor-level cleaning that brings older units back to life, pricing well below competitors, and zero upselling pressure. The review base is small, which is the main caveat.
Pros
- Pricing cited as significantly lower than competing quotes
- Thorough cleaning including compressor work on older units
- No upselling, honest assessment of what actually needs doing
- Technician Mr Ali praised by name for meticulous work
Watch-out:Only 14 reviews, so confidence is medium and the sample is too small for a fully reliable read.

CoolFix Aircon - Aircon Service, Installation & Repair in Petaling Jaya
score 75/100Why it ranks #13
CoolFix Aircon scores 74.8 across 12 reviews with strong sentiment (0.81). Customers report same-day leak fixes and cooling restorations within hours, responsive WhatsApp communication, and no hidden charges. The very small review base is the honest caveat here.
Pros
- Same-day service and on-time arrival confirmed across reviews
- Effective leak repair and cooling restoration within hours
- Transparent pricing with no hidden charges
- Responsive WhatsApp communication for quick booking
Watch-out:Only 12 reviews, making this a low-confidence pick despite strong individual feedback.

FAST AIRCOND SERVICES & ENGINEERING
score 68/100Why it ranks #14
FAST AIRCOND scores 67.9 and carries 346 Google reviews and a 4.8 rating, which represents a large real-world track record. The composite score is pulled down significantly by a recency sub-score of zero, meaning there are not enough recent reviews to form a reliable current sentiment read. Treat past performance as a reference, not a current guarantee.
Pros
- 346 reviews represent one of the larger track records in this list
- 4.8 Google rating across a high review volume
- Full service scope including repairs and installations implied by volume
- Established presence in the PJ market
Watch-out:Low confidence: the recency score is zero, meaning recent review activity is insufficient to reliably assess current service quality.
Services:aircon gas top up, central vrv vrf, aircon servicing, aircon installation

Global Air-Cond Service
score 72/100Why it ranks #15
Global Air-Cond scores 72 with 27 reviews and high confidence. Routine servicing is typically done within two hours with the site left clean, and technicians are noted as courteous. Recent complaints about unresolved leaks, unclear parts charges, and poor service documentation are a real concern and pull the score to the bottom of this list.
Pros
- Technician arrives within 1-2 hours of booking
- Routine servicing completed in under two hours
- Work area left clean with no mess
- Courteous, professional staff during the visit
Watch-out:Recent complaints flag unresolved water leaks after service, overcharging for parts, and poor record-keeping that makes follow-up difficult.
