About Us

Grant Park Heating & Cooling was founded on a simple belief:

Residential homes deserve the same level of expertise, precision, and innovation that commercial buildings get — without the sales pressure.

 

Nick Hansen, founder and lead technician, has spent years studying airflow, equipment design, climate impact, and heat-pump technology. While many contractors follow outdated “rule of thumb” sizing or push equipment that isn’t right for Wisconsin’s climate, Nick takes a completely different approach:

 

✔️ Evaluates the structure of each home

✔️ Designs systems around airflow, humidity, and comfort

✔️ Specializes in high-efficiency and dual-fuel heat pumps

✔️ Prioritizes long-term reliability and accurate design over shortcuts

 

Every system we install is AHRI-matched to ensure proper compatibility and performance. We also complete all manufacturer warranty registrations on behalf of the homeowner, and provide emailed confirmation so customers always have full proof of coverage on file.

 

Nick has contributed his expertise to statewide clean-energy discussions, collaborated with industry partners, and helped homeowners transition into modern comfort without losing reliability.

His approach is simple: fossil fuels and green energy can coexist. Modern comfort technology should serve the homeowner —and when people see how it works, it's often exciting. 

 

Grant Park Heating & Cooling was named after the park Nick grew up exploring.

It reflects everything our company stands for: family, community, and respect for our environment.

 

We’re proud to bring advanced HVAC technology, honest guidance, and high-quality installations to homes throughout the Milwaukee area.
