The company is good, but the furnace installer is very bad. The installation site was messy and unprofessional. His attitude was very bad and he always blamed his boss for excuse. After opening the box, he put all the spare parts in his bag. he doesn't care about your property. Some things were damaged during the installation process. I heard his colleague call him "John". Please contact the company to see if the installer is John, if so, please say "NO". I don’t know why they use John to damage the company’s reputation.
