Our Process

We will help you throughout the whole life of your HVAC system, from conception to completion to updating.  We have over forty years of experience doing all projects, large and small.
Capitol Mechanical will work with you to determine the best HVAC system for your project. Once a system is selected, our design engineers will produce a quality estimate that is efficient, of high standards and competitive. We will meet with you to present our recommendations and discuss and answer any questions you may have.
We realize that open communication is important for your project to be successful.  During the design process, we will collaborate with other design professionals working on your project to ensure you have the best possible outcome.  We have state licensed HVAC designers on staff with years of experience and the latest design technology so we can handle questions, changes, and updates promptly.
We have an experienced field team that is highly skilled and up to date with current industry systems and standards.  They work closely with our design team to make sure your project is kept on track. Our project managers visit your site regularly to ensure coordination between all parties. If any issues arise, our design and field teams work with other trades to ensure the project is staying on task.
We will provide initial training, technical manuals and as-built drawings so you have all of the technical knowledge you need. We recognize that we are turning over a live system for your use and we will show you how to use your system to its full potential.  This way you will be able to be in control.
We design our systems with long life and low maintenance costs in mind.  We offer preventative maintenance contracts so you can keep your costs steady and predictable.  Our service technicians are highly skilled and trained on a wide variety of HVAC systems.  They are ready 24/7/365 to care for your system.
We have expertise on transitioning to new systems.  We’ve worked on many retrofits over the years including historical remodels.  By assessing your current needs we can improve your system with the most current processes and energy efficient equipment.
