How to ask customers for reviews: a guide for HVAC and plumbing contractors

A completed service call is a natural point to invite honest feedback. This practical guide covers timing, sample wording, and the different rules that apply on Google, Yelp, and under Federal Trade Commission guidance.

When should a contractor ask for a review?

Ask after the job is complete and the customer has had a fair chance to understand what was done. For an HVAC repair, that may be after the system has been tested and the technician has explained the result. For a plumbing repair, it may be after the fixture or line has been checked and the customer knows the work is finished. For a replacement or larger project, use the handoff or walkthrough as the natural close.

There is no source-backed, universally best number of minutes or hours to wait. The supplied research snapshot gives conflicting windows and does not establish an optimal time. Treat the timing above as a practical workflow choice, not a proven way to increase review volume: make the work complete, then send a neutral invitation at a consistent point when the customer can respond if they choose.

Keep the invitation separate from the quality check. Ask all customers who meet the same completed-work criteria, rather than only people who praised the technician or seemed likely to leave a high rating. If someone raises a concern, respond to the concern directly; do not steer that person away from an honest public review.

A simple, respectful review-request process

  1. 1

    Close out the real job.

    Confirm the work is complete, record what was done, and give the customer a clear handoff. Do not ask someone who has not actually received the service.

  2. 2

    Use a channel the customer expects.

    Use the agreed follow-up channel and keep the request easy to recognize. If you are unsure whether the customer wants follow-up there, ask first instead of assuming.

  3. 3

    Invite an honest account, without pressure.

    Say that a review is optional, link directly to the appropriate review page, and let the customer choose their own words and rating.

  4. 4

    Keep the same rule for every customer.

    Do not filter requests by satisfaction, offer a reward for a particular rating, or ask a customer to include a technician’s name or specific talking point.

Review request examples for HVAC and plumbing jobs

Replace the bracketed details with accurate information. These are examples, not claims about a real customer or business.

Text message · Google

Hi [Customer name], thanks for having [Company name] repair your [heating / cooling / plumbing] system today. If you’d like to share an honest review of your experience, you can do so here: [Google review link]. It’s completely optional, and any honest feedback is welcome. — [Technician or company name]

Email · after an installation

Subject: Optional feedback on your [system / plumbing] installation

Hello [Customer name], thank you for choosing [Company name] for your [installation or service]. Now that the work is complete, you’re welcome to share an honest review if you’d like. You can use this link: [Google review link]. There’s no obligation, and your feedback can be positive, mixed, or critical. Thank you, [Name]

Google provides instructions for creating and sharing a review link or QR code, including using it in a thank-you email or on a receipt. Use your own Business Profile link; do not copy the bracketed placeholder above as a destination. See Google’s instructions for review links and QR codes.

Google, Yelp, and FTC review-request rules are different

A request that is acceptable on one review site may violate another site’s rules. Choose the destination before sending, and check its current policy rather than treating “review request” as one universal practice.

Google: neutral requests are allowed; incentives and review gating are not

Google says businesses can share a review link or QR code to make it easier for customers to leave feedback. Its Maps policy also prohibits incentives in exchange for a review and says businesses must not discourage negative reviews or selectively solicit positive ones. Do not request a particular star rating, wording, or a review written on the spot. Read Google’s review-link guidance and its Maps policy on fake engagement and rating manipulation.

Yelp: do not ask customers to review you there

Yelp draws a stricter line than Google. Its U.S. Business Terms prohibit businesses from soliciting or asking their customers for reviews. Do not send a Yelp review link as part of a customer request campaign. See Yelp’s U.S. Terms of Service and Business Terms (effective January 1, 2026).

FTC: incentives are not all treated the same

FTC marketer guidance says not to ask people who have not used the service, not to ask only customers expected to be positive, and not to condition an incentive on a positive review. The FTC’s current rule FAQ says the rule does not ban every incentive for an honest review when no particular sentiment is required, but an incentive may need to be disclosed under the FTC Act. Platform rules can be stricter: Google prohibits review incentives, and Yelp prohibits solicitation. The simplest approach for a service contractor is to skip review rewards. Read the FTC’s guide for marketers soliciting or paying for reviews and its Consumer Reviews and Testimonials Rule Q&A.

Should you send a review-request reminder?

A reminder is optional; a non-response is not a problem to solve. The available research snapshot does not establish an ideal reminder interval or show that a reminder improves results for HVAC or plumbing contractors. If your customer has agreed to follow-up on that channel and the destination’s rules allow it, you can decide whether one brief, low-pressure follow-up fits your service process. Stop if the person declines or opts out, and do not keep sending messages.

Keep any follow-up neutral: “Just a quick note in case you meant to share feedback about [job]. If you’d like to, here is the link again: [review link]. No need to respond if you’d rather not.” Do not imply that a customer owes the business a review.

How ReplyPilot fits into review follow-up

ReplyPilot’s current review-request workflow requires an owner to record the customer’s explicit consent and take a separate action. Saving a request does not send it, and ReplyPilot does not automatically send or schedule review requests or reminders. Review-request delivery is not currently available because a workspace-owned email or SMS provider is not connected. This guide’s examples are for a contractor’s own manual process; they are not a ReplyPilot sending feature.

ReplyPilot’s public product walkthrough covers a different part of the workflow: managing Google reviews and preparing replies for owner review. See the ReplyPilot review-reply walkthrough.
