By providing your mobile number and checking a consent box, you agree to receive automated text messages from Kelvin at that number. Transactional messages (demo information, appointment and account notifications, and service updates) are sent if you check the transactional consent box. Promotional messages (occasional seasonal HVAC service offers and reminders) are sent only if you separately check the optional marketing consent box. Consent to receive texts is not a condition of any purchase.
Message frequency varies based on your interaction with us. Message and data rates may apply depending on your carrier plan. Kelvin is not responsible for carrier charges.
Reply STOP to any message to stop receiving texts, or HELP for help. Carriers are not liable for delayed or undelivered messages.
