In the morning I noticed it was very cold in the house even though my thermostat was indicating that the furnace was running. Soon it became apparent that the flame wasn't coming on, so I browsed HomeStars and called AccuServ. They had a technician available in the 15-17h slot, and as I indicated that the job needed to be done before 17h as I had to leave, they also signified to the technician to come closer to 15h. Sure enough, at 14:45 Erich came over, diagnosed and fixed the issue. He was very professional, and also gave me good advice on how to keep my furnace and other appliances in good working order. I was very satisfied with the quality, professionalism and timelines of AccuServ service and Erich's job in particular, and can easily recommend them for similar services.
