About Us

Welcome! We're the Wu family, founders of Dad And Son HVAC. After moving to America, I (Daddy Wu) and my son Jacob decided to bring our passion and expertise in HVAC to our new community. With over a decade of hands-on experience from our home country, we are dedicated to delivering reliable, high-quality heating and cooling services to our neighbors in Belvidere and beyond.

Starting a new life in a new country isn't easy, but our family values—hard work, honesty, and care—remain the same. We believe that every customer deserves to feel comfortable and confident in their home. That's why we treat every job as if we were helping our own family.
