Enbridge came and give me a red tag and gave me notice for 4 weeks to fix my problem. I was so worried about tag and eventually, I called Cambridge heating to help me. Tech canes the next day and resolve my problem and charge just $99.I was extremely glad. I have been very pleased with the service and courteous personnel of Cambridge family heating and cooling. My furnace stopped working suddenly and they came right over and fixed the problem. They are also on time.
