Best HVAC service in the northwest suburbs

I have always gotten excellent service from Althoff!


Rachael was very professional and courteous while helping me schedule my appointment. Greg Daru, service plumber, was excellent! He introduced himself as he arrived; very respectful of my property. He was genuine and friendly. He explained everything very thoroughly, in a way that I could understand. He provided equipment manual; dated equipment replaced. Thank you, Greg, for an excellent experience!

I have used Althoff for years because of the quality of their people. I would not use anyone else.

I have been using Althoff for many years and they have always been very responsive and professional whenever I have needed a technician.

A very professional and pleasant company to work with. Knowledgeable staff and customer focused. Highly recommend.


My brother-in-law referred us to Althoff, and I cannot thank him enough for recommending such a group of competent and friendly professionals. I only wish I had learned about Althoff 20 years ago!

Alex was a very though Technician. I appreciate his work on my furnace. Thank you for such great service.
