GrowOutly for Home Services

Phone Software for Home Service Businesses

In home services, the phone is the storefront. A missed call is usually a job booked by a competitor, and the most profitable calls you make go to customers you've already served. GrowOutly answers, routes and follows up from one number.

The short answer

Home service businesses earn most from answering every inbound call and from repeat customers. Route calls to whoever is free, forward to technicians in the field, and follow up on estimates and tune-ups. Calling past customers is usually allowed, but automated calls to cell phones still need consent.

The phone is the storefront

Most home service work starts with an inbound call: a broken AC in July, a leak under the sink, a panel that keeps tripping. Customers call the first two or three companies they find and book whoever answers. For a small shop with every technician in the field, the hard part isn't getting calls. It's answering them.

Outbound calling matters in a different way. The best revenue goes to customers you've already served: estimates waiting for a yes, maintenance plans up for renewal, seasonal tune-ups before the first heat wave. These calls go to people who know you, and they're the ones a busy owner most often skips.

Answering every call

Set up inbound routing so the business number rings whoever is available: the office first, then an on-call technician, then voicemail-to-text after hours. When everyone is out on jobs, call forwarding sends calls to the owner's or technician's mobile with the business number displayed. Any unanswered call becomes a callback task with a one-tap redial.

If you'd rather have calls answered even when nobody can pick up, GrowOutly for Support adds an AI Agent. It answers, takes booking requests and quote details, and passes the caller to a person when needed.

Calling past customers

Two sets of federal rules define an established business relationship. Under the Telemarketing Sales Rule, it's a purchase within 540 days or an inquiry within 90 days. Under the FCC's rules, it's a purchase within 18 months or an inquiry within 3 months. Either way, a past customer on the Do Not Call registry can usually still be called about a tune-up or renewal.

The relationship is a Do Not Call exemption, though, not a consent exemption. In 2012 the FCC removed the old rule that let businesses make prerecorded telemarketing calls to existing customers' home phones without consent. The TCPA has never allowed autodialed or prerecorded calls to cell phones on the strength of a relationship alone. Calls placed by a person, one customer at a time, are the safe default for repeat business. Anyone who asks you to stop calling must be removed, whatever the relationship.

Selling in the customer's home

When a technician sells something in a customer's home, such as a new system, a water heater or a maintenance plan, the FTC's Cooling-Off Rule usually applies. That covers sales of $25 or more made at the buyer's home. The customer can cancel until midnight of the third business day. You must tell them so orally and give them two copies of a cancellation form, and you must refund within 10 business days of a cancellation.

There are two exclusions for service businesses. Repairs the customer specifically requested are excluded, though extra goods or services sold on that visit, apart from necessary replacement parts, are not. And a customer who called about a genuine emergency can waive the right with a separate, dated statement in their own handwriting. Make sure your office scripts and technicians' paperwork match these rules.

Recording calls

Recorded calls settle disputes about what was quoted and when the crew was promised. About a dozen states require every party's consent to record, including California, Florida, Illinois, Maryland, Massachusetts, Pennsylvania and Washington, and Connecticut and Nevada for phone calls. If you take calls from more than one state, add a short recording notice to your greeting and treat every call as all-party.

Setting up a home service business in GrowOutly

  1. Route the main number by business hours, with an on-call mobile after hours.
  2. Turn on call forwarding for owners and technicians in the field.
  3. Add a recording notice to the greeting if you record calls.
  4. Text arrival windows and estimate follow-ups from the business number, with quiet hours by time zone.
  5. Each morning, work open estimates and due tune-ups with the power dialer, and book visits straight into the calendar.

Frequently asked questions

Can an HVAC company call past customers about seasonal tune-ups?
Usually, yes. Under the FCC's rules, a purchase within the last 18 months or an inquiry within the last 3 months creates an established business relationship, so the Do Not Call registry doesn't block the call. The relationship doesn't cover autodialed or prerecorded calls to cell phones, which still need the customer's consent, and anyone who asks you to stop must be removed.
Does the 3-day cooling-off rule apply to emergency repairs?
Not if the customer called you for a genuine emergency and signs a separate, dated statement in their own handwriting describing it and waiving the right to cancel. Repairs the customer specifically asked for are also excluded, but extra products or services sold on that visit, apart from necessary replacement parts, are covered.
