Best Heating Unit in Milwaukee WI

Count on Hartlaub to do right by the customer. Totally professional across the board, they care that you understand what they're recommending and why, and give you/your home their total and undivided attention during service calls--unlike other places that just want to get it done and get over to the next job or go home. They've brought in additional help or expertise, at no extra cost, to ensure that they're proposing the best solutions. When employees of a company really like working there and are supported by leaders to do their best work, it shows. Hartlaub's done major work at our home and we'll continue to be loyal customers.

Air conditioner went out the Sunday before Labor Day. O&W came out within the hour. Replaced worn out part and cleaned unit. They explained everything in detail. Very impressed and happy with work done. Will call back for estimate on new furnace.

Excellent service and job well done. Scott and Andy know how to get the job done

Highly recommend

Kurt did a great job, and answered all of my questions regarding my existing furnas.

Great job by Mark K!

Horrible Home Depot. Everyone is always walking around doing nothing and never wants to help when asked. Poor customer service

Brian & his staff of workers are professional & have been very good in providing great service.
