How we score air conditioning contractors in Malaysia

Who publishes this directory

The Malaysia Air Conditioning Contractor Guide is published by Meridian Guides, which has produced independent city directories for everyday services across Malaysia since 2025. The rankings are maintained by John, Editor, who oversees the method and the monthly data checks. You can reach the team at hello@meridianguides.my.

Right now the guide scores 1017 businesses. Each one gets a composite score from 0 to 100, built only from public customer reviews and the contact details a business lists.

The five signals and their weights

Meridian Guides sets its own weighting, within fixed limits, and applies the same weights to every listing. Here they are, heaviest first.

Signal	Weight	What it measures
Volume	35%	How many reviews, log-scaled
Rating	25%	Google aggregate star rating
Sentiment	20%	Recent review themes: praise versus complaints
Recency	10%	How recently customers reviewed
Completeness	10%	Phone, website, hours and address listed

Volume (35%)

Review volume carries the most weight here. A long run of reviews is hard to fake, and it shows a contractor has served many customers, across many jobs like servicing, gas top-ups, and new installs. The count is log-scaled, so depth counts without sheer size winning on its own. Going from 5 reviews to 50 moves the score a lot. Going from 500 to 550 barely moves it.

Rating (25%)

The Google star average is the quickest read on overall satisfaction. We use it as a strong input, but not the leading one, because an average alone can hide a lot.

Sentiment (20%)

Sentiment counts toward every score. We synthesise recent review themes and weigh praise against complaints. This is how the score catches repeated problems, such as missed appointments, leaks after installation, or units that need a second visit, which a 4.5 star average can smooth over.

Recency (10%)

Air conditioning firms change. Technicians leave, and service standards slip or improve. Recent reviews tell you how the business performs now, not years ago.

Completeness (10%)

A listing with a phone number, website, opening hours and address is easier to contact and check. A contractor you cannot reach or locate is a practical risk when your unit breaks down.

What does not change a score

Scores are earned from this rubric and this data only. They are never edited by hand. Paid placement, when it exists, is always labelled and never changes the score. If any list has picks or an order that an editor reviewed, that is disclosed on the page itself.

How fresh the data is

We refresh listing data monthly. Each listing carries a "last verified" stamp so you can see when it was last checked.

Honest limits

• Low-confidence scores. A business with few recent reviews gets a low-confidence score and is labelled that way. Treat it as a starting point, not a verdict.
• We synthesise, not republish. We summarise review themes rather than copying reviews. Each listing links out to Google so you can read the source yourself.
• Reviews are not inspections. The score does not check licences, technical skill, or warranty terms. Ask for a written quote and confirm the details before work starts.
• Reviews can be gamed. Volume and sentiment make this harder, but no method removes the risk entirely.
