A very competent young technician from Jack Lehr came to perform the heating inspection on our furnace on 10/10/2017. He typed up a thorough description of the many tests he performed that indicated the good health of our furnace. Besides being technically savvy, he was courteous, on time and very helpful. For example, he demonstrated how we could use the "auto" setting on the thermostat which would better make use of switching from furnace to air-conditioning during autumn when outside temperatures can fluctuate greatly. He also demonstrated how to properly install and uninstall the furnace filter. (I never noticed the pull-taps, before! Ha! We have confidence in Jack Lehr and we have and will continue to recommend their expertise and service to others.
