Our Services

Delivering cost-effective, high quality HVAC systems

Through our proprietary applications of Trade Management, Value Engineering, and Design / Build services, KSW approaches projects from the perspective of the end user.

We evaluate final cost and installation efficiency – ease of operation, maintenance, and operating costs – in our design solutions. We work collaboratively with engineers and clients, from concept to implementation to ensure alignment between systems design and client expectations.

We usually start at the construction phase of building, but KSW can also successfully evaluate a completed design to provide alternative, economical HVAC systems solutions.

At KSW, we pride ourselves on a long, successful track record of lateral thinking, resulting in a successful project portfolio delivering quality systems on time, within budget.
