Marketing Compliance

What you can and can't do when marketing your HVAC business — by channel, with penalties.

This is NOT legal advice. It's a plain-language summary of federal and Florida rules that affect how HVAC contractors market. Laws change, enforcement varies. Consult an attorney before launching any marketing campaign you're unsure about.

Channel-by-Channel Rules

ChannelConsent needed?Opt-out required?Main lawPenalty per violation

Advertising claimsN/AN/AFTC Act + FL FDUTPA$10K–$53,088

Email (CAN-SPAM Act)

Opt-out, not opt-in. You can email past customers without prior consent. But every commercial email must include: a working unsubscribe link, your physical address, honest subject lines, and clear identification of who's sending it.

Transactional vs commercial: Appointment confirmations and invoices are mostly exempt. Promotional emails (tune-up offers, referral requests) must comply fully. Mixed-content emails are judged by primary purpose.

Penalty: up to $53,088 per non-compliant email. Each email is a separate violation.

Text Messages / SMS (TCPA)

Opt-in required. Customer must agree in writing to receive marketing texts before you send the first one. Appointment reminder consent does NOT cover marketing messages — you need separate consent for each.

10DLC registration

Since February 2025, all major carriers block unregistered business text traffic entirely. Your texting platform (ServiceTitan, Housecall Pro, Podium) should handle registration as your Campaign Service Provider.

FCC one-to-one consent rule (January 2026)

Consent must be given to one specific business at a time. Lead forms that share data with multiple companies no longer provide valid consent for marketing.

TCPA lawsuits are growing fast Filings were up 95% year-over-year through mid-2025 (ActiveProspect). Penalty: $500-$1,500 per text. In a TCPA lawsuit, the burden of proof is on you — if you can't produce the consent record, you lose. Keep consent records at least 5 years.

Phone Calls (TCPA + TSR + Do Not Call)

Three separate federal rules apply, plus state rules.

The established business relationship (EBR) exemption

This is what lets you call past customers even if they're on the Do Not Call list:

RelationshipHow long you can callConditions
Purchase/transaction18 months from last purchaseMust stop if customer asks
Inquiry/application3 months from inquiryMust stop if customer asks
No relationshipCannot call if on DNC list—

In HVAC terms: repair in March = you can call through the following September (18 months) to offer a maintenance plan. But the moment they say "stop calling," you stop. Forever. Penalty: up to $53,088 per call after a stop request.

Telemarketing Sales Rule requirements

Robocalls and autodialers

The EBR exemption does NOT apply to autodialed or prerecorded calls to mobile phones. Your CSR can manually call a past customer within the 18-month window. But you cannot put them into an automated calling system without written consent.

Online Reviews

FTC Fake Reviews Rule (Oct 2024): up to $51,744 per violation, per day for ongoing violations.

Advertising Claims

Florida-Specific Rules

License number in advertising (FL §489.119)

Your contractor license number must appear on every advertisement, bid, offer, or proposal — website, vehicle wraps, business cards, yard signs, social media profiles, Google Business Profile, print ads, door hangers, uniforms.

Florida FDUTPA

Florida's consumer protection law is broader than federal and easier for consumers to use — individuals can sue directly. Penalty: up to $10,000 per violation ($15,000 if the victim is a senior citizen, disabled, or military). Plus attorney's fees.

Florida Do Not Call list

Separate from the national registry. Scrub against both before outbound calling campaigns.

What Records to Keep

The cheapest compliance move Use a real marketing platform that handles opt-outs, consent logging, and DNC scrubbing automatically. Spot-check it quarterly. Keep your records. When in doubt, ask your attorney before you send — one hour of legal time is cheaper than one TCPA class action.
