John M. was very thorough, courteous and professional. During his furnace check, he provided an update on our aging furnace and suggested we start planning for its eventual replacement. But for now, everything is working. He replaced a part on our humidifier and explained how to use the system. He also installed a new filter (which we already had) and answered some questions about our thermostat. John M. went the ""extra mile"" and I will request him in the future.
