Direct Energy called proactively to arrange my annual furnace maintenance and inspection as part of the Heating protection plan we pay for. They allowed me to select the date and select a 4 hour time window for the maintenance to be carried out. Service technician came during this scheduled window, put protective covers/slippers over his footware as he came into our house to complete the maintenance. Afterwards he reviewed the work, the findings, provided some answers to some questions that I had. Quick, efficient, polite and quite quite. I was pleased with the service, his advice and answers to my questions. I would recommend the benefits of the annual inspection and heating protection plan for older furnaces like the one we have.
