Company Overview

Founded in 1913, Fennig Plumbing, Heating & Air Conditioning and is proudly managed by 3rd generation owner Louie Fennig, delivering a comprehensive range of plumbing, hydronic/boiler heating, furnace heating, and air conditioning services.

Being a family-run company for over a hundred years, Fennig Plumbing and Heating was established in 1913 when Charles Fennig, preferring not to inherit his father's role, started his plumbing venture in the basement of his father's establishment: Fennig Funeral Home located at 5th and Lincoln in Milwaukee.

For 75 years, from 1915 to 1990, Fennig Plumbing functioned at the corner of 13th and Lincoln on Milwaukee's south side. The business moved in 1990 to its current site at 68th and Mitchell in West Allis, with a home office based in New Berlin.

Louie offers a practical approach, personalized service, and quality to upgrade plumbing fixtures, install water heaters, cool your home or warm up your basement.

The specially designed trucks improve service by having a diverse selection of parts and tools readily available. Our West Allis facility is structured to ensure that everything is quickly located, along with specific tools for bending sheet metal, pipes, and more.

Louie Fennig replaced our old failing furnace & air conditioner back in 2005 one cold October day. Fast forward to Decembet 2021 and the furnace stopped working. One call to Fennig Heating and Louie was on his way to our house at 7pm! He accurately diagnosed the problem and got the furnace running with a little work-around. At 10am the next morning he called back to let us know that he had the replacement part in hand. An amazingly quick visit - and before noon we were back to 100%.

I highly recommend this amazing service company.

5 Stars for sure!

Based on an earlier review, I decided to contact Louie and ask about a shower and faucet install. He was prompt with returning my call and I made an appointment for him to come take a look. He was very professional with the assessment and talked me through a few scenarios what might happen removing the existing parts and during the install. The job went smoothly and he finished the same day. He had all the parts he needed in his truck to complete the work. I would definitely recommend him to friends and family if they ever need repairs. I am a happy customer and am enjoying my new shower!

I recently bought my first home and know next to nothing about home ownership beyond writing the mortgage check. Right after I purchased my home, I asked another company to come out and do a regular maintenance on both of my furnaces (the home is a duplex). That company was more concerned with locking me into a contract for yearly service and coming up with their list of expensive repairs for one of the furnaces. Since I had purchased the home from an HVAC tech, I was suspicious enough to think something was up. The husband of my coworker is a general contractor and I asked him to recommend someone so I could get a second opinion. He quickly recommended Louie, saying that Louie always does everything right the first time, and now I can't say enough good things about Louie.

Right after I received the dire news that I was living in a death trap because the one furnace was supposedly a fire hazard, I had to go to Australia. While I was out of the country, and never having met Louie, he came over and looked at the furnace for me to let me know what was the real truth. I remember being in Sydney on the phone with Louie and thinking that he really could take advantage of the situation if he were so inclined. Instead, he came over, looked at the furnace, let me know that all of the things that this other company had said needed to be changed were completely unnecessary (that was almost four years ago and the furnace has never missed a step) and did this all free of charge. Needless to say, I have only used Louie since, for both my HVAC and my plumbing. He always returns my call, is there when he says he will be or lets me know he is on his way, and never tries to sell me something I don't need. He is very good about showing me what is going on, and always explains things in a manner that is easy to understand without insulting anyone's intelligence. Louie is responsible, dedicated, honest and personable. It is so nice having someone you can trust. Highly, highly recommend him.
