Best New Furnace in Milwaukee WI

Can't say enough about Jack Hanley and Erik Thode.
They were extremely courteous and professional. They answered all our questions and then hooked us up with one of their licensed electricians. Have always used Hartlaub for all our plumbing needs. Highly recommend them!

After calling several other HVAC contractors and having them tell me they couldn't come and get my furnace going for several days I came upon O & W in a google search. I read the reviews and decided to give them a call and couldn't be happier with the result! Omer was here within an hour of my call. He did a thorough cleaning of our furnace and got it running again. Sadly, it failed again the next day and Omer returned and diagnosed a faulty gas valve. Within one day he had that replaced and had us warm and toasty again! I would highly recommend this business to anyone seeking quality repairs from extremely knowledgeable technicians.

Had a great experience with Kurt. Very professional, on time, and knowledgeable.

All around great company. Very easy to work with and very knowledgeable staff. Highly recommend, will definitely use again.
