  Jeremy was great! He inspected our furnace today so that there are no surprise issues this winter. Very through and advised us on which filters we should use for our furnace.

  Technician arrived in a timely manner. He checked my hot water heater and unfortunately I need a new one. I expected that. Cary was friendly and knowledgeable. I'm always happy with the work they do. .

  Was informed when Harrisen was going to arrive, wore booties in my home, and kept  me informed of his progress on our furnace maintenance. He  was extremely polite. Very professional. Always a good experience with this company!

  I am happy to share our extreme pleasure with the outcome of our electrical project and the AJ Danboise contractor, MAHER KASSHAMOON, who got us there.

We had a multitude of electrical upgrades and repairs done to our home: electrical wiring added to ceilings that had none; electrical outlets, switches and dimmers added; recessed lighting installed throughout the home; new light fixtures and ceiling fans installed in most rooms, and repair of our outdoor electrical outlets.

This project affected the majority of the rooms in our home. Yet, despite its size, it was flawlessly executed by Maher. From the beginning (quoting process) to the end (project execution and completion), he was simply amazing!  He was professional, kind, customer-focused, knowledgeable and a problem-solver.  He helped us tremendously and has unquestionably earned our five star rating.  Thanks to him, the vision for our home has been brought to life.

Also, a special shout-out to Alex who worked with Maher in the earlier stages of the project. Alex was yet another amazing asset on the AJ Danboise team.  (Talent and skills apparently run deep in this organization and my husband and I were grateful beneficiaries of it.)
