How is the 0-100 score calculated?

It's a weighted composite of five signals: sentiment (28%), rating (26%), volume (20%), recency (12%), and completeness (14%). Sentiment and rating carry the most weight because they reflect actual customer experience, while volume and recency adjust for how much and how current that evidence is.

Why does sentiment matter more than the star rating?

Star averages can mask patterns. Two contractors can share the same rating while one has recent reviews repeatedly mentioning the same problem. Reading what reviews actually describe catches issues a single number can't show, which is why sentiment is weighted highest.

Can a contractor pay to rank higher?

No. Rankings come only from the rubric and the underlying data. Where paid placement exists, it is clearly labelled and it does not affect a business's score.

What does a low-confidence label mean?

It means the business has few recent reviews, so the score is built on less evidence. We flag these listings so you can weigh them accordingly rather than treating them the same as a business with a long, recent review history.

How we score aircon contractors in Tampines

SG Tampines Aircond Contractor Guide currently scores 130 air conditioning contractor businesses operating in and around Tampines. Every score comes from a single rubric applied the same way to every listing. This page explains what goes into that rubric, why we weight it the way we do, and where the data falls short so you can read our rankings with the right amount of trust.

The five signals, heaviest first

Each business gets a composite score from 0 to 100, built from five measured signals. We list them here in order of how much they count.

Sentiment, 28%. A synthesis of what recent reviews actually say: recurring praise, recurring complaints, and whether problems get resolved or repeated.
Rating, 26%. The business's aggregate star rating on Google.
Volume, 20%. How many reviews a business has, log-scaled so that ten reviews and five hundred reviews don't get treated as equally reliable, but a small contractor with a handful of solid reviews isn't buried either.
Recency, 12%. How recently customers have actually left reviews. A contractor whose last review is three years old tells you less about today's service than one reviewed last month.
Completeness, 14%. Whether basic business information is actually listed: phone number, website, operating hours, and a physical address.

Why sentiment carries the most weight

A star average on its own hides patterns. Two aircon contractors can both sit at 4.3 stars, and yet one of them has a string of recent reviews all mentioning the same thing, a technician who no-shows, a quote that changes after the job starts, a gas top-up that leaks again in a month. The star number alone won't tell you that. Reading what reviews actually describe is the only way to catch it, which is why sentiment sits above even the rating itself in our weighting. Rating still matters a great deal, and volume and recency exist to stop a handful of old reviews from carrying more weight than they should. Completeness rounds things out: a contractor who lists a working phone number, hours, and an address is easier to actually hire, and that basic transparency belongs in the score.

Where the score is weaker

Some businesses in Tampines simply don't have much of a review trail yet. When a listing has few recent reviews, the resulting score is less reliable no matter how good the underlying work might be, and we label those listings as low-confidence so you know to weigh them differently. We also don't republish reviews wholesale. What you read on a listing page is our synthesis of the themes running through recent reviews, and we link out to Google so you can read the original source reviews yourself and judge the tone directly.

Paid placement, clearly labelled

Rankings are earned from the rubric above and nothing else. Where paid placement exists on this directory, it is always labelled as such and it never changes a business's score. A contractor cannot buy a higher position in the rankings.

Who publishes this directory

SG Tampines Aircond Contractor Guide is published by SG Homee Guides, running since 2025. Sam Lee founded SG Homee Guides after a decade working inside Singapore's local home service trades, with direct experience across air conditioning, plumbing, renovation, and locksmith work. That background shaped how this directory is built: listings come from published review data and public business information, rankings are earned through verified work rather than purchased, and contractor data is rechecked every month so the directory stays current. Only contractors that meet the directory's standards appear here.

Sam Lee, Managing Editor, maintains the rankings and oversees the editorial standards behind them. Data across the directory refreshes monthly, and each listing carries a "last verified" stamp so you can see exactly when it was last checked, not just when it was first added.
