I called on Monday to request cleaning/maintenance on propane wall heater at my rental property, left message with their answering service--a live person! Call was returned the following day with appointment scheduled for Wednesday between 12:30-2pm. Jeremy arrived exactly at 12:30. He was pleasant, polite and knowledgeable. Service completed, I asked if he had time to go to my home for possible future installation of mini-split system---and again, very helpful and clearly knew what he was talking about. Will definitely call them if/when I choose to proceed with that project, or future maintenance/repair on heater at my rental. Very happy!
