What We Do


Simply put, our job is to provide you with clean, safe and comfortable indoor air quality. It is not only what we do, but it is what you deserve.

We know that there are other companies out there that do what we do, so why us?

R. Williamson & Associates has over 135 years of experience in applying, supplying, designing, installing and servicing systems related to air movement and air pollution control. We’ve learned some things along the way, and it allows us to best serve our clients with minor to major ventilation issues whether they be end users, contractors, engineers or Original Equipment Manufacturers. We have seen a lot but will never see it all so we are always looking for new challenges.

I know, you have heard it all before, so what makes us different? We pledge to be available and accessible, to get you the answers you need to make your decisions for your business or plant operation when you need them.

R. Williamson & Associates is an honest and knowledgeable company resulting in 5 generations of service to industry. Each generation strives to be better than the last. Our solutions are innovative, efficient and effective and we vow to provide you with what you need, sometimes more, but never less. We are committed to providing safe, reliable, long lasting solutions and relationships that allow both of us to have confidence in our decisions.

Equipment Supply

As a manufacturer’s representative, we work closely with several proven manufacturers of commercial and industrial ventilation equipment. The manufacturers are leaders in their industry and understand that our clients have goals and that we and they are required to meet their expectations for timeliness, quality, and engineering support. We believe our core group of products meet the demands to ensure long-life and successful operation of your commercial and industrial ventilation systems. To augment our manufacturer’s product offerings and to meet a client’s needs we will supply specified products or make our fabrications and assemblies to meet project requirements. Our goal is to achieve installed system longevity with the best components applied in the correct manner.

Installation & Start-up Services

R. Williamson & Associates offers installation and start-up services for all of the equipment we sell. Our installation partners are knowledgeable both in the intricacies of the equipment as well best design practices. Our installation services range from basic consulting services to complete turnkey projects. Taking complete responsibility for a project allows the project to be completed on time and correctly.

Custom Equipment

At R. Williamson & Associates, extraordinary is ordinary, and custom applications are what we are built on. All of the manufacturers and installers that we work with understand that commercial and industrial applications are like snowflakes, and no two applications are exactly alike.  Most systems require a few special design “tweaks” to provide the optimal end result. We work with all types of construction materials to suit your needs, including carbon steel, stainless steel, Monel, Aluminum, PVC and FRP and more, allowing us to work in almost any environment.

Replacement Parts and Support Services

Servicing the equipment that we sell provides you the client, the confidence that you need that you need to know that we can keep you up and running. With over 135 years of experience we have developed a vast network of support services in all of the areas that we service. We carry records of each and every sale dating back to the mid 1900’s. Those records contain not only the base equipment details but also the corresponding parts lists and any other service that may have been provided. Why?  So we can be more prepared than the other guy.

Field Analysis and Testing

All of our equipment is factory tested and balanced prior to shipment. Over time rotating equipment can experience performance changes due to normal use. These changes can be due to field conditions, build up, vibration and balance issues. We offer complete test and balancing services for all of our fans, blowers and rotating equipment. These services can also be used for performance tweaks to increase or decrease performance as well.  Whether a new installation or collection of data for a new design, R. Williamson & Associates will analyze and report the findings necessary for you to make a qualified decision.

Education and Training

Educating our clients is as important to us as knowing the information ourselves. We offer training in the form of on-site startup services, consultations and group presentations. We offer several lunch & learn presentations for architects and engineers that provide Continuing Education Unit (CEU) credits allowing for a simple means of continuing education while getting a free lunch. The better our clients understand our solutions, the better the systems they we are designing and installing will be.  This education keeps you current and makes you knowledgeable about the latest solutions available in the marketplace.

Meeting Expectations

Meeting expectations is what is most important to us. You have an expectation of a solution that is efficient and effective. Our goal is to meet that expectation by providing the proper equipment for your application and implementing the solution that works best for you on your timeline. To ensure that we meet your expectations we are very thorough. We do our best not to be overbearing, but our questions and your answers lay the foundation for a successful and smooth project. How do we meet expectations? We do this by:
  • Our Proposal – supplying the most innovative, efficient and effective solution for the application.
  • Our Manufacturers – furnishing correct information and getting commitments from our suppliers so they understand the client’s expectation.
  • Communication – Good news or bad news, we vow to communicate project information to you. We are always available via phone, email and in person. To provide the kind of service expected of us we’ve located technical sales associates throughout our assigned geographic area. And, because we work frequently throughout the United States with corporate accounts and relocating clients, we will go to a jobsite when needed.
  • People – R. Williamson & Associates knows the meaning of service. At R. Williamson & Associates we have the support system it takes to get it done right. From application technicians, secretarial staff, accounting and sales, we bring the team together to focus on each project no matter the size.
  • Experience – we’ve been doing this for over 135 years and have an idea where projects might go wrong and prepare accordingly.
Our role as a manufacturer’s representative is to continually work with our suppliers and our clients to get it done. Whether you need a complete system, a single piece of equipment, a drawing, a direction or a specification, give us a call, and we’ll be there for you.
