Best Ductless Heating Systems in Milwaukee WI

Ryan did an excellent job installing a new faucet in our kitchen. The service prompt and effecient.

Angel came and did a plumbing inspection and he was so polite, on time and explained everything to us.
Adam came and did a furnace check up and cleaning. Was on time polite and honest. Explained everything to us. Very happy with Hartlaub. The women answering the phones are always so upbeat and friendly.

They install the new furnace and new outlet, then I also professionally installed whole house humidifier, After couple weeks furnace stop working! It was still under warranty but they DIDN'T fix it , They said no warranty because someone install the humidifier! I have to pay to fix it!

I have worked with JM Brennan on many projects and their dedication to customer service is top notch! They have developed a culture at their organization that is second to none in the Mechanical Contractor space. Their prices are fair and transparent and the staff does a great job of presenting the appropriate sense of urgency!
