Design + Planning

We start by working with our customers to fully understand their needs and goals. Then we begin the back-and-forth process of modeling and eliciting feedback.

Our models layer critical information over visual representation, so our clients better understand the proposed design. This detailed insight allows us to make corrections early in the design process.

Value Engineering

​​Some view value engineering as settling for the cheapest options. But at Century, it’s about designing HVAC systems that meet or exceed project cost objectives without compromising our high standards for quality and performance.

We work with your team to examine alternative options in engineering design, equipment, material, construction, operations, and maintenance. Our primary role is to identify opportunities to improve performance, reduce cost, and add value.

Building Information Modeling

Design + Production

Our BIM-detailed 3D models identify potentially disruptive construction issues so we can resolve them early in the design process.


BIM enhances collaboration by showing us how one stage of construction will impact another, giving us the clarity necessary to work together effectively.

Advantages of BIM

Comprehensive 3D visualization

Better communication and collaboration

Better understanding of design intention

Less rework and revisions

More-efficient planning and scheduling

Fluid hand-offs between stages

Less waste of materials

Accurate as-built drawings at handover

Indoor Air Quality

Well-filtered and ventilated air inside our buildings is a Century imperative. We design systems that meet or exceed ASHRAE standards. We enhance building wellness by improving air quality; eliminating harmful viruses, bacteria, and particulates; and maximizing efficiency.


We design and build our systems to bring in more air from outside to reduce airborne contaminants and improve indoor air quality.


Installing humidifiers/dehumidifiers can significantly improve comfort and can prevent respiratory issues, static electricity, and mold and bacterial growth.


We ensure that the coils are clean and free of restriction. And, we install higher-rated MERV filters such as MERV 11 or MERV 13, so your system can effectively move and filter the air.


We can install ionization and irradiation units to remove bacteria, viruses, and other particulates in virtually any forced-air system.

Hyper-efficient heating and cooling systems help make buildings more affordable to build and operate and keep people comfortable without heating the planet.

Proper Ventilation

Your HVAC system doesn’t need to run as long or as often with proper ventilation. Ventilation also improves indoor air quality and reduces moisture-related problems.

System Zoning

Dividing your space into HVAC zones is a very efficient way to use only the energy you need—by controlling the temperature in each zone separately according to occupancy and time of day.

Heat Pump Technology

Heat pump technology removes heat from the air and moves it inside or outside, depending on whether a space needs heat or air conditioning.

Properly Sealed Ductwork

Leaky and poorly connected ducts equate to a lot of wasted energy. Doing something as simple as properly sealing heating and cooling ducts can improve HVAC efficiency by 20% or more.


Variable-speed Systems

Typical HVAC systems have two speeds, on or off. A variable speed drive can modulate speeds to be more energy efficient.


Worksite Safety

​​Health and safety are our top priority, so we do everything necessary to keep everyone safe on the job.

OSHA Training

Every Century team member is OSHA certified, completing 10 hours of safety training. Project forepersons receive an additional 20 hours of training.

ABC Gold

​​We’ve achieved Gold status in ABC’s STEP Safety Management System, which means we are 655% safer than the industry average.

Site-Specific Planning

We implement a comprehensive Health, Safety, & Environmental (HSE) program on every project, accounting for the unique risks of the job site and project objectives.

Independent Inspections

Our job sites are inspected by independent 3rd-party professionals to ensure that our safety plan is effective.

Site Supervision

Each project has an assigned health and safety representative responsible for all aspects of the safety program.


Each employee understands and is responsible for their Health, Safety, and Environment Management (HSE) compliance.

Toolbox Talks

We hold short weekly safety meetings to make our team aware of possible workplace hazards and provide updates on OSHA regulations.

COVID Protocols

We maintain onsite protocols such as providing and requiring proper PPE and hand-sanitizing stations, encouraging social distancing, and avoiding physical contact as much as possible.



We take slow and costly building processes away from the job site and into our streamlined prefab shop to enable quick and easy installation. In-house assembly helps us reduce waste, improve our systems' quality, and shorten our delivery cycle.

Saves Time

In-house assembly creates a more efficient supply chain with fewer links in the chain between your project design and the installation process. We can complete a 4-month project in as little as 6 weeks.

Quality Assurance

We know our components are built to our high standards.

Tailor Made

Each piece is designed and built precisely to your unique requirements.

Less Waste

By controlling the complete fabrication process, we reduce overall waste, save money, and reduce environmental impact.

Installing new commercial heating and cooling equipment can save up to 40 percent on monthly energy costs.


An optimized HVAC system runs more efficiently. The people who inhabit the building enjoy better indoor air quality, humidity control, and more consistent temperatures.


Retrofitting is usually a fraction of the cost of investing in a completely new system, so your return on investment can be as little as 1 year.


Replacing worn parts and making strategic upgrades can enhance the entire system’s lifespan.

Are your utility bills rising?
Has your heating or cooling become uneven?
Are your repair costs continually rising?
Is your system making unusual noises?
Is your system producing strange odors?
Is your HVAC system over 10 years old?
Is energy being lost through the exhaust?
Are there visible signs of malfunction?


Aeroseal Duct Sealing

There’s nothing more frustrating to a building owner or operator than watching your building’s operation dollars unnecessarily vanish into thin air.

As a certified Aeroseal provider, we use patented duct-sealing technology to pinpoint duct leakage and inject polymer particles to fill holes, cracks, and gaps from the inside. We can seal leaks that are nearly impossible to reach using other methods.

ASHRAE estimates that 75% of buildings have 10% – 25% air duct leakage.

How do you know if your ducts are leaking air?

Higher Energy Bills

Loss of air increases fan use leading to higher energy bills. Duct sealing can often pay for itself in energy savings.

Unhealthy Air Quality

Duct leakage generates excessive dust and can even contaminate the air with harmful viruses, bacteria, and particulates.

Hot and Cold Spots

Improper air balance can cause problems with building airflow. Using Aeroseal technology, you'll have greater temperature control.


Leaky ductwork may cause “back-drafting," where gases (like carbon monoxide) are drawn back into the occupied space rather than expelled outdoors.


Planned Maintenance

Commercial HVAC maintenance is like getting a tune-up for a car. Regular quality maintenance on your systems and equipment ensures that those systems are not wasting energy due to faulty performance.

Taking a proactive approach can reduce maintenance costs by up to 40%. Century technicians' in-depth knowledge is invaluable to properly maintaining your HVAC systems and equipment.
