Bought and annual contract after Service call on unit in September 2019. Set up a winter service call, semi-annual in Mid-December. Was contacted day before and 30 minutes prior to Tim's arrival. Courteous, professional and very knowledgeable on Heating System. Discussed services performed today. Let me know diagnostics on the unit and shape of overall system.Very happy with this Company and looking forward to them servicing my unit for many years.
