Why should you choose us as your HVAC contractor? That is a question we welcome. We get it - it can be overwhelming picking someone, let alone knowing what questions to ask.

So why us? We are always technicians before salesmen. We work hard behind the scenes to come up with options that make sense for your unique situation. We plan it out in detail with all parties involved to ensure you’ll have a cohesive team. We take the time to listen to your concerns and answer all of your questions. And that’s even before you officially choose your contractor.

So give Duke Mechanical a call. We are looking forward to working together on your next project.

You did a great job Jim, these Bosch heat pump systems are great for homes that want to have a balanced distribution throughout the home through ductwork. Mini splits are not the only option. We specialize in ductwork and hand make it in our shop. More importantly, happy to have you as a partner on this job. See you on the next one🤙 (also, washing my van this weekend haha)
