About the company…

Nielson Mechanical has always focused on the customer’s needs, using creative solutions that best fit their project needs. We can design and install commercial and residential heating and air conditioning systems and controls to fit our customer’s needs. When we started, our focus was on single-family dwellings. As we evolved, our focus has moved to primarily commercial projects.

Specializing in HVAC Design & Engineering

We specialize in designing and constructing customized HVAC systems. Our specialties include packaged rooftop units, split system air handlers, infrared heating systems, make-up air units, kitchen hoods, and specialized exhaust systems. We also do cooler/refrigeration design and installation. Our design-build department provides energy calculations, model energy code compliance, auto-cad prints, and engineering stamps.

Experienced & Professional

Our team has worked on mid to large highrise projects, offering everything from complete design-build services to scalable design-assist services for the full mechanical package. These projects cover a wide range of settings, including corporate office, retail, medical, education, restaurants, car dealerships, manufacturing and production facilities, as well as boilers, chillers and cooling towers.
