HVAC, PLUMBING & ELECTRICAL.
DONE RIGHT SINCE 1925.

HVAC, Plumbing & electrical. Done right since 1925.

Whatever your home needs, AJ Danboise has been the team that Metro Detroit homeowners call for 100 years.

A Michigan Family with Over a Century of Trust.

Alex Joseph Danboise opened a plumbing and hardware shop at Grand River and Spokane in Detroit in 1925. He wasn’t thinking about a hundred-year legacy — he was thinking about showing up and doing the job right. That part hasn’t changed.

His son Hall took over in 1966. Hall’s daughter Carol came to work alongside her father after college, and eventually brought in a young plumber named Jack Gatewood — who she later married. When Hall passed away in 1978, Carol and Jack stepped in and kept going. Jack earned his Master Plumber’s license and Mechanical Contractor’s license. Together they grew the business and moved it from Detroit to Redford to Farmington Hills, turning a neighborhood shop into the full-service company it is today.

In 2017, Carol’s daughter Amy became the fourth-generation owner. The fourth generation of the family is already learning the trades. A hundred years in, and it’s still the same family — still showing up for Metro Detroit homeowners one job at a time.

 Trustindex verifies that the original source of the review is Google. Silvio did an excellent job! He was professional throughout, clearly explained the work upfront, and walked me through the completed checks afterward. I’m very pleased with the service and would highly recommend Silvio for HVAC services.

 Trustindex verifies that the original source of the review is Google. Kevin (Office Manager) Chris (HVAC Technician) & after hour lady (since my call was after AJ Danboise's office hours) were great in addressing our HVAC problem that came to light upon completion of our Fall HVAC maintenance completed on Monday (11/9/26).
This is the 2nd time that both Kevin & Chris addressed our problem and resolved both issues in a very timely (& cost saving) manner.
Danboise's "Always Here Plan" yearly plan is well worth the cost - includes electrical, plumbing & HVAC.

 Trustindex verifies that the original source of the review is Google. I honestly can't say enough good things about A.J. Danboise. They are an exceptional company, and I have trusted them with my home's heating, plumbing, and electrical needs for years.

I especially want to recognize Jeremy and Steve. Jeremy, in particular, has been servicing my boiler ever since it was installed, and his knowledge and expertise are truly outstanding. I live in a home that's over 100 years old, and anyone who owns an older home knows that it can come with some unique challenges, especially when it comes to heating systems.

Over the years, Jeremy has spent countless hours and made numerous service calls helping keep my boiler running properly. He knows my system inside and out. When an emergency comes up, he knows exactly what to look for, how to troubleshoot the problem, and how to get things back up and running. His ability to understand an older system, think outside the box, and find practical solutions is impressive.

More importantly, Jeremy gives me something you can't put a price on: peace of mind. Knowing that someone with his experience and knowledge is taking care of my heating system is incredibly reassuring. I have complete confidence in his work, and he is the one technician I trust with my boiler.

I also want to recognize the entire A.J. Danboise team. From heating and plumbing to electrical work, they have helped me maintain, repair, and improve my aging home. Everyone has been accommodating, professional, dependable, and trustworthy.

It's not easy finding a company you can rely on year after year, especially when maintaining a home that's more than a century old. A.J. Danboise has consistently earned my trust, and I wouldn't hesitate to recommend them to anyone.

Five stars without hesitation. Thank you, Jeremy, Steve, and the entire A.J. Danboise team for taking such good care of our home!
