How many hot water system specialists does Starworks rank in Parramatta?
Starworks ranks 11 hot water system specialists in Parramatta, NSW, holding 287 Google reviews between them. Across the 11 the median rating is 5.0 stars from a median of 3 reviews. Of the 11, 8 are rated 4.5 or better and 1 has passed 100 reviews.
What star rating should I expect from a good hot water system specialist in Parramatta?
The median Google rating across the 11 hot water system specialists Starworks ranks in Parramatta, NSW is 5.0 stars, and 8 of them sit at 4.5 or above. A rating at or near that median is ordinary for hot water system specialists in Parramatta, NSW rather than a warning sign on its own, and a rating well above it only means much when enough reviews stand behind it.
How many Google reviews does an established hot water system specialist in Parramatta have?
The median hot water system specialist Starworks ranks in Parramatta, NSW carries 3 Google reviews, and 1 of the 11 hot water system specialists have passed 100.
How does Starworks rank hot water system specialists in Parramatta?
Starworks gives every hot water system specialist in Parramatta, NSW a reputation score out of 100 from three things: its Google star rating (up to 47 points), how many reviews back that rating (up to 35), and whether customers can reach it by website and phone number (up to 18). Review volume is the one part that can subtract: below 15 reviews it costs points, because a near-empty review record gives a stranger very little to go on. No score falls below 0 and placement cannot be bought. The score measures the strength of a business's public review record rather than the quality of its work, so it is worth reading the reviews as well, and every listing links to them on Google.
Why does a hot water system specialist in Parramatta with all 5-star reviews score lower than one with a lower rating?
Because review volume counts as well as rating, and below 15 reviews it counts against you. Five perfect reviews are encouraging but thin evidence; three hundred reviews averaging 4.7 tell a stranger far more about what to expect on the day. That is a judgement about how much proof exists, not about the quality of the work, and a newer hot water system specialist with a handful of excellent reviews may still be the right choice in Parramatta, NSW. The star rating and review count sit next to every score so you can weigh both yourself.
Why does the same hot water system specialist not appear several times on this list?
Some businesses run more than one Google listing, often one per suburb they service. Those are the same company, so Starworks groups them and shows the business once, using the listing with the strongest review record. That is why this page opens with 11 distinct hot water system specialists in Parramatta, NSW rather than a longer list of repeats.
How often is this list of hot water system specialists in Parramatta updated?
This ranking of hot water system specialists in Parramatta, NSW rebuilds on a 30-day cycle and prints the date of its last rebuild above the list, which for the current version is October 2026. Ratings and review counts are re-read from Google over time rather than on a fixed schedule, so an individual figure here can be older than the rebuild date.
How can I improve my hot water system specialist business ranking in Parramatta?
Collect genuine customer reviews consistently, and keep a working website and phone number on your Google listing, because those are the three inputs the score reads. There is no placement to buy on this page. For scale: the median hot water system specialist Starworks ranks in Parramatta, NSW carries 3 Google reviews at 5.0 stars.
