My furnace was leaking water at a crazy rate, and they were able to quickly come out, discover the problem and fix it! Very personable and gave great advice about everything hvac related in house
We had a new AC and Heater installed. Althoff were professional and I would highly recommend this company to all of my friends and family!
Service men are courteous and qualified always on time which respects your time also.
We've used Althoff's for a long time because they're on time and do great work. Technicians that know what they're doing and can actually repair problems not just replace parts work here.
Althoff is by far the best HVAC companies in the Chicago land area. Timely, courteous, knowledgeable, and really care about your satisfaction.
Phenomenal Service!!! Salesman (Jeff Miller) was responsive and really cared about making us happy. Service Technician was top notch. I've found my forever home service company!
