Best New Air Conditioner in Milwaukee WI

This was the first time I used Hartlaub and I was extremely pleased with the service I received. Isaac and Jeff were absolutely amazing and took the time to explain the services provided and did incredible work. I don't plan on using another company besides Hartlaub moving forward! A+

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.

Over priced compared to other heating

Got the drain unclogged but left a mess in basement which I had to clean up. Don't know if this is standard operating procedure

Andy was very professional and as busy as he was, he fit our little project in. Very professional and very courteous. It was kind of an odd project, but he worked with us. And for the price, can't beat the workmanship. Very satisfied. Thank you.
