How we score air conditioning contractors in Malaysia
Malaysia Air Conditioning Contractor Guide currently covers 986 air conditioning contractor businesses across the country. Every score on this site is calculated the same way, from the same public data, using the method laid out below. Nobody adjusts a score by hand after the fact.
What goes into the composite score
Each business gets a score from 0 to 100, built from five measured signals. They're weighted like this, heaviest first:
| Signal | Weight | What it measures |
|---|---|---|
| Sentiment | 28% | A synthesis of what recent reviews actually say: praise vs recurring complaints |
| Rating | 26% | The Google aggregate star rating |
| Volume | 20% | How many reviews exist, log-scaled so a handful of reviews doesn't score like hundreds |
| Completeness | 14% | Whether phone, website, hours and address are all listed |
| Recency | 12% | How recently customers have actually left reviews |
Why sentiment carries the most weight
A star average flattens everything into one number, and that number can hide a real pattern. Two air conditioning contractors can sit at the same 4.3 stars while one gets praised for tidy installs and turning up on time, and the other quietly collects repeat complaints about gas leaks, no-shows, or a unit that stops cooling a month after install. The stars alone won't tell you which is which. Reading what recent reviews actually describe is the only way to catch that difference, which is why sentiment is weighted above the star rating itself.
Why the other signals matter
Rating still counts for a lot, because it's the single most-trusted shorthand customers use, and it reflects the judgment of everyone who left one. Volume matters because a business with 5 reviews and one with 400 aren't equally proven, so review counts are log-scaled rather than compared raw. Completeness matters for a trade like this one: if a contractor doesn't list a working phone number, hours, or an address, that's friction (or risk) for anyone trying to book a repair or install. Recency matters because a contractor's team, pricing, and quality can shift over a year or two, and reviews from three years ago say less about who'll show up at your door next week than reviews from last month.
The honest limits
This method has real boundaries and we'd rather state them than hide them. Businesses with few recent reviews don't have enough signal to trust fully, and those get a low-confidence label on their listing rather than being scored as if they were well-established. We synthesize themes from reviews rather than republishing them word for word, and every listing links out to the source on Google so you can read the original reviews yourself. A score is a starting point for comparison, not a replacement for checking recent reviews and getting a quote.
Paid placement and editorial disclosure
Scores are earned from this rubric and this data alone, and they are never edited by hand. Where paid placement exists on this site, it is always labelled clearly and it never changes a business's score. If any list on this site has picks or an order that were reviewed or adjusted by an editor rather than generated purely from the rubric, that is disclosed on the page itself.
Who publishes this
This directory is published by Meridian Guides, founded in 2025. Meridian Guides runs independent city directories for everyday services across Malaysia, and it builds its rankings on a published scoring method drawn from public customer reviews, a method that is never sold for payment. Sponsored listings are always labelled as such, and they don't affect where a business ranks. Editorial oversight of these rankings sits with John, Editor, who maintains the method described on this page. Listing data is re-checked monthly, and each listing carries a "last verified" date so you can see it's being actively maintained rather than left to go stale. You can read more about the publisher at meridianguides.my, or reach the team directly at hello@meridianguides.my. To browse contractors ranked by this method, head back to the home page.
FAQ
- How is the air conditioning contractor score calculated?
- It's a weighted blend of five measured signals: sentiment from recent reviews (28%), Google star rating (26%), review volume on a log scale (20%), listing completeness such as phone, website, hours and address (14%), and how recently reviews were posted (12%). The result is a single 0-100 score.
- Why does sentiment matter more than the star rating?
- Because a star average can hide patterns that matter. Two contractors can share the same rating while one has recurring complaints about a specific problem, like leaking installs or missed appointments. Reading what recent reviews actually say is the only way to catch that, which is why it's weighted above the raw star rating.
- What does a low-confidence label mean?
- It means a business hasn't collected enough recent reviews yet to score with real confidence. Rather than treat thin data as if it were solid, we label those listings so you know to weigh them differently.
- Can a business pay for a higher score or better ranking?
- No. Scores come only from this published rubric and public review data, and they are never edited by hand. Where paid placement exists, it's always labelled and it never changes a business's score. Any list where picks or order were editor-reviewed discloses that on the page.
