Full Disclosure

Delta Controls does not go to market through distributors, like Stromquist & Company, so I have never sold Delta Controls. I have competed against Delta Controls through our contractor network, so I can tall you that they are a reputable company that stands behind their products, and their partner in Atlanta is a very good systems integrator.

Because I am not a Delta dealer, I do not know all the ins and outs of their product offering and might have missed some things, if I have please let me know so I can make corrections, and be sure to visit their website.


Delta Controls provides a robust building automation control system, carrying a well-deserved reputation backed by a history of successes.

One potential concern could be the limited options on where and how you can purchase Delta Controls. As we highlighted in our discussion about selecting a building automation control system in 2023, having a variety of companies that can offer competitive bids and service the building control system of your preference may be worth considering.

If Delta insists on its partners meeting the same excellence as their products, their market approach should not pose a significant concern for most.

Delta is a solid choice, next up for review, Automated Logic.
