I called to have winter check on my two furnaces. The company scheduled me for the next business day, the technician arrived on time, was polite and efficient. The technician also covered his shoes to protect my interior. I’m one of those people who like to leave the outdoors out. The technician showed me how to replace the filters as well as writing down the size for each furnace. He gave me his card should I have any issues and was on his way.
