Best Hvac Replacement in Milwaukee WI

We had a big basement water issue (building on the Milwaukee river). Quote was fair. Mid-project they got creative and saved us at least 20%. Very happy with the result.

Very thorough and helpful. Clean and professional. I was even shown how to adjust temperature and flush. Thank you!

Outstanding service at a very fair price!!! Omer was very professional and thorough explaining step by step the process of examining our water heater and giving us an honest and professional opinion on the best and most cost effective options... Service was fast had our new water heater installed the next day and stand behind his work with a warranty to back it up... Thank you Omer and I will definitely be referring you to all my family and friends...

I had Tim visit to survey my plans for a bath renovation. He was very professional, and provided all answers to my questions. I look forward to working with him in the future.

Showed up on time. Friendly service tech, patient, willing to answer questions and provide suggestions. Would recommend these people.

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!

They were recommended to me by my contractor friends in milwaukee, had them out for a couple of jobs, great work, great folks!

Our sump pump failed and Seider sent Jason around the same morning I called, and replaced it for the quoted price. Jason was polite, efficient and did a great job. Would definitely recommend.

Ripped me off and over charged me for work that was not done...Spoke to owner, he agreed to reimburse me the $800 (ish) call several times in the following year because I hate to feel swindled. . NEVER GOT THE STOLEN MONY BACK! Also to add insult to injury, I recently tore apart my bathroom to remodel and the new plummer said the workmanship sucked. He asked me if it was a handyman from craigslist...THIEVES!!!

Anna in plumbing was very helpful !

I love they free learn workshops.....
