Total Comfort NWI gave excellent service while diagnosing then replacing my malfunctioning furnace/air conditioning unit. I received a prompt and supportive response through customer service representative via their website at 4 am on a Saturday with an initial visit later that same morning. Customer Service notified me via text message and phone call of their arrival times. Their findings were explained fully given with great care to answer all questions giving education as needed to make sure that I understood the full picture. Time and care was given to understand my life style and needs to determine the options available for repair or replacement. While replacing the unit, these specialists were friendly and presented themselves in a non-rushed manner. They kept me informed of the operation during all phases of the replacement. They treated me and my home with respect. Very tidy and conscientious. Overall quality was exceptional. Their pricing for the emergency call and all their work was very reasonable. The replacement unit is of great quality. It was easy to see that they have pride in their service. I am very impressed with this company and recommend them to all. Thank you, guys, for your help and support!.
