“We have a high-end Trane HVAC whole house system that was installed and serviced by another HVAC company in Bend. Recently, on a chilly day, our heating system stopped operating. We immediately called our HVAC company for service, but only got their answering service who could not help us. Finally, we reached a grumpy customer service rep that was indifferent to our problem and told us that we might have to wait 2.5 weeks to get service. I immediately called Diversified Heating and Cooling (they service a rental house that we own) and reached Lisa K, the dispatcher. Lisa was very pleasant, helpful and knowledgeable – she had me run through some quick checks and then scheduled a service call for the next day. On schedule, David showed up the next day and found the problem – a mouse had eaten through the wire that goes to the heat pump’s ambient temperature sensor. David was great. – professional, skilled, friendly and respectful of our property. The heating system is now running, the part is on order and we could not be happier. THANK YOU LISA K AND DAVID – EXCELLENT CUSTOMER SERVICE and TECHNICAL SUPPORT!! We will never use another HVAC service company again.”
