Great Service Technician Was Awesome
The technician arrived checked everything out inside and went to work checking out the AC, checked and cleaned everything and did a great job. He asked if I had any questions before he left and I said no, but will see you again in the Fall for the furnace checkup.

Adam - Bolingbrook, IL 60490-3234
Great Service
Mark was great. He identified himself as being with Tempco Heating & AC. He went to work and explained what he was going to check and make sure our furnace was ready for the heating season and answered any and all questions I had. He also explained we would be contacted prior to the next visit so we would be ready for the next AC season.
Gary - Aurora, IL 60502
Service
Mark is excellent. Great job answering questions and took his time to clean our furnace. After 18 months MI homes associates told me on at least two occasions that as long as the light was on the fresh air fan was working. It was NOT and Mark found the wires incorrectly connected. Also the flyer we received in the mail was very misleading. No need for a quality company like Tempco to use such misleading flyers
