Review velocity for HVAC companies: a steady flow beats a big push, within the rules

What "review velocity" means, and what's actually documented

Review velocity is marketing shorthand for how often new reviews arrive. You'll hear claims that Google rewards a certain number per month. Be careful: Google has never published that.

What Google does say, in its tips to improve your local ranking, is that prominence is one of the three main factors, and "more reviews and positive ratings can help your business's local ranking." It also says there's no way to request or pay for a better ranking. On its review score help page, Google says the score is the average of all ratings published on Google, and an updated score can take up to two weeks to show.

So the documented part is simple: more genuine reviews and better ratings help. The case for a steady flow, rather than a burst, comes from how homeowners and AI answers read reviews.

Why recent reviews matter to the people who call you

BrightLocal's Local Consumer Review Survey 2026 (1,002 US adults, published February 2026) found:

• 74% of consumers look for reviews from the last three months, and 32% look for reviews from the last two weeks.
• 47% won't use a business with fewer than 20 reviews.
• 80% say they're likely to use a business that responds to all its reviews, and half are put off by generic, templated replies.

That's a US sample, not Ontario, but GTA homeowners searching for a furnace repair in January behave much the same: they want proof that someone like them was happy recently.

Why recent reviews matter to AI answers

AI tools read reviews, they don't just count them. Google launched review summaries written with Gemini in Google Maps in October 2024, and its Maps grounding for Gemini retrieves reviews along with hours and addresses. The same BrightLocal survey found 82% of respondents read AI-generated review summaries.

Review counts also line up with who gets named. A September 2026 study by 8ight.AI, reported by PPC Land, asked ChatGPT about 39 trades across 49 places, 17 of them in the GTA. ChatGPT named 3.4% of tested businesses with fewer than 25 Google reviews, against 22.2% of those with 1,000 or more. Treat that carefully: it's vendor research, it measured the API rather than the ChatGPT app, and it shows a correlation, not a cause. It still fits the common sense view that a thin review profile is easy to skip.

The rules, in plain words

Google's rules

Google's Maps content policy and its tips to get more reviews say:

• No incentives. Offering free or discounted goods or services for reviews is strictly prohibited. That includes "$25 off your next tune-up for a review".
• No selective asking. Businesses may not "selectively solicit positive reviews from customers". This rules out review gating: sending a "How did we do?" survey and only passing the happy customers to Google.
• No discouraging negative reviews.
• No conflict-of-interest reviews. Employees, former employees, family and people with a contractual tie to you shouldn't review you.
• Reviews must reflect a genuine experience.

Google encourages you to share a review link or QR code. Asking is fine. Asking only some people, or paying, is not.

Canada's rules

The Competition Bureau's January 2024 notice on employee reviews says employees must disclose all connections they have with the business, even when their opinion is honest, and that businesses that write or allow reviews giving a false or misleading impression can be liable under the Competition Act. The Bureau suggests training staff and having a compliance program.

In practice: tell your technicians not to review the company, and not to ask friends and family to.

A note on US rules

You may see the US Federal Trade Commission's 2024 rule banning fake reviews quoted in marketing articles. It's US law, not Ontario law, but it points the same way: no fake reviews, no AI-written reviews, no incentives tied to a positive review.

A routine that keeps reviews coming

1. Ask everyone, at the same moment

Pick one moment and stick to it, for example when the technician confirms the system is running and the invoice is paid. Ask every customer. Consistency is what keeps you clear of "selective" asking, and it's what produces a steady flow.

2. Make it one tap

Send a text or email with your direct Google review link (you can get it from your Business Profile). A QR code on the invoice or the technician's tablet works for in-person asks.

3. Ask for detail, not stars

A line like "If you have a minute, it helps other homeowners if you mention what we fixed and roughly where you are" leads to reviews such as "Furnace wouldn't ignite on a Sunday night in Etobicoke, they had it running in an hour." That kind of review helps homeowners and gives AI summaries something specific to repeat. Don't script the wording, and don't ask for five stars.

4. Reply to every review, like a person

Thank happy customers and mention the job. Reply to unhappy ones once, calmly, with a way to reach you. Avoid identical copy-paste replies; the BrightLocal survey suggests homeowners notice.

5. Watch the monthly count, not the daily one

Write down your review count and average on the first of each month. If the count stalls, it's usually because the asking stopped (a new technician, a busy week), not because of the algorithm.

How many is enough?

There's no official number. The useful comparison is local: search your main service and city, and look at the review counts of the businesses in the map pack and in AI answers. If they have 300 and you have 40, the gap is the work. If you're close, focus on recency and replies.

Seasonal timing helps too. GTA HVAC companies do most of their visits in the first cold snaps and the first heat wave, so that's when the most review asks go out. See our Ontario HVAC calendar for when those peaks usually land.
