We have been very pleased with our experience with Reliance to date. Ever since our system was installed, from dealing with sales rep Lawrence Kelly, to Dustin and his team who completed the installation, to today’s service call with Nuam who was extremely helpful, patient and thorough with a thermostat installation. We are very pleased with the service received from Reliance. Thank you
