How to Get More Google Reviews for a Plumbing or HVAC Business

When a plumber stops the leak, the homeowner has just experienced relief on a problem that was ruining their day. When an HVAC tech gets the AC blowing cold in July, the customer is genuinely grateful. That moment — tech wiping down, paperwork signed, customer visibly relieved — has the highest review conversion rate of any moment in any industry. Plumbing and HVAC companies that systematize this ask routinely outpace competitors on review volume by a wide margin. Here's how.

1. 1

   Train every tech with a 30-second on-the-job script

   At the end of every job, after the customer has confirmed the issue is resolved: 'Glad we got that sorted, Mr. Garcia. Quick favor — if you have 20 seconds, would you mind leaving us a Google review? My name's in the review and it really helps our crew.' That's the script. Every tech. Same words. Practice it in the morning meeting until it's automatic.

2. 2

   Have the tech hand a physical business card with a QR code

   A small business card with the tech's first name on the front and a Google review QR code on the back. The customer scans on the spot or keeps the card. Cards with the tech's name on them convert much better than generic company cards because customers want to credit the specific tech who fixed their problem.

3. 3

   Send an automated SMS 30 minutes after the job is marked complete in the FSM

   If the customer didn't review on the spot (most won't), an SMS arrives shortly after the tech leaves. 'Hi Sarah — it's Mike from Garcia Plumbing. Thanks for having me out today. If you have 20 seconds, mind leaving us a quick Google review? [link]. Reply STOP to opt out.' The 30-minute delay captures the customer once they've had a moment to enjoy the working sink/AC/whatever.

4. 4

   Reward techs based on asks logged, not reviews received

   Tracking 'reviews per tech' rewards luck (which customers happened to follow through). Tracking 'asks logged per job' rewards the behavior you want. Many FSM platforms let techs tap an 'asked for review' button on the job. Bonus the asking, not the rating — bonusing on rating risks FTC issues under the 2024 reviews rule (16 CFR Part 465) and Endorsement Guides (16 CFR Part 255).

5. 5

   Skip the ask for cancelled, refunded, or repeat-issue jobs

   A customer who had to call you back for the same issue isn't a happy customer — even if you fixed it the second time. Suppress automated asks on jobs flagged as callbacks. Asking imports awkward 2-star reviews and damages your average. Catch them after the next successful interaction instead.

6. 6

   Reply to every review with the tech's name

   'Glad Mike got that sorted for you, Sarah — I'll let him know.' Mentioning the tech by name in the public reply (a) makes the tech feel valued, (b) signals to future customers that you have specific techs who do good work, and (c) builds tech-level reputation that helps with hiring.

7. 7

   Place a yard sign for visible jobs (with permission)

   For multi-day jobs or visible installations (new HVAC unit, drain line replacement), ask the customer if you can leave a small yard sign for a few days. The sign carries a QR code and 'See why neighbors trust Garcia Plumbing — read reviews on Google.' Yard signs in some markets generate meaningful incremental review volume from neighbors over time.
