The TCPA and CAN-SPAM compliance playbook tailored for hvac contractors — TCPA class actions don't discriminate by trade size — every SMS to a non-consented number is a $500-$1,500 hit.

Key Takeaways for HVAC

  • Transactional SMS (appointment confirmation, review request after a AC installation) needs Prior Express Consent — a lower bar.
  • Marketing SMS (cross-sell, win-back, promotional) needs Prior Express Written Consent — a higher bar with checkbox + disclosure.
  • 10DLC registration is mandatory for business SMS. Without it, carriers throttle or block your messages entirely.
  • Quiet hours: 9 AM-8 PM in the recipient's local timezone. Stricter than federal default, satisfies all state rules.

Why this matters for HVAC businesses

HVAC businesses send a lot of SMS — appointment reminders, "tech on the way" notifications, review requests, promotional offers. Each non-compliant message exposes you to $500-$1,500 per-violation TCPA penalties. A single class action settles in the $1M-$10M range for businesses your size.

The HVAC-specific angle

For hvac contractors, the key consent boundary is between transactional and marketing SMS. A review request tied to a completed AC installation is transactional — prior express consent suffices (the customer gave you their phone number for service purposes). A win-back campaign or cross-sell promotion ("need a furnace tune-up?" to an AC customer) is marketing — requires prior express written consent with a checkbox. License #s also matter on the SMS side if you reference services that require licensing in your state. Your license-required states for hvac include: California, Florida, Texas, Arizona, Nevada, Oregon, Washington.

A hvac business sending 1,000 marketing SMS without proper PEWC consent is exposed to $500,000-$1.5M in TCPA liability. The plaintiffs' bar specializes in finding these.

How Apex HVAC would set this up

Consider Apex HVAC, a hvac operation serving Austin, TX. A typical AC installation job at the 742 Maple Drive address triggers the following automation:

  1. Technician taps "Job Complete" in the field — AC installation marked done.
  2. 4 hours later, Sarah receives an SMS asking for a Google review.
  3. Review request mentions AC repair specifically — feeds Local Pack keyword relevance.
  4. If Sarah leaves a 4+ star review, a 25-card postcard campaign fires to neighbors around 742 Maple Drive.
  5. Sarah also gets a referral link — both they and a referred neighbor get a discount on the next job.
  6. Compliance: 9 AM-8 PM quiet hours respected, opt-out logged, license # auto-included on postcards where required.
