IEC EnviroKIT: A Sustainable Retrofit for Fan Coil Units

Aging fan coil units are a common challenge in hotels, apartments, healthcare facilities, and senior living properties. Many buildings were designed decades ago, and while the cabinets may still be structurally sound, the internal components are often inefficient, noisy, and expensive to maintain. Full replacement sounds appealing on paper, but it usually comes with major drawbacks like high labor costs, long room downtime, and invasive construction.

IEC’s EnviroKIT® offers a different approach. Instead of tearing out the entire fan coil unit, EnviroKIT retrofits the equipment already in place by replacing only the critical internal components. The result is a modernized system that delivers improved performance, better energy efficiency, and extended equipment life without the disruption of a full replacement project.

For facility managers and building owners looking to upgrade HVAC performance while controlling budgets, EnviroKIT provides a practical and sustainable solution.

What Is the IEC EnviroKIT Retrofit System?

EnviroKIT is a custom-engineered fan coil retrofit package designed specifically for vertical stack fan coil units. Each kit is built to match the dimensions and operating requirements of the existing equipment, allowing installers to upgrade performance while keeping the original cabinet in place.

Typical EnviroKIT packages can include:

• High-efficiency EC motor fan assemblies

• Updated control systems

• Replacement coils

• New drain pans

• Electrical upgrades and wiring components

By focusing on the components that actually impact performance, EnviroKIT delivers the benefits of a new unit without the cost and complexity of removing walls, modifying piping, or rebuilding enclosures.

Why Retrofit Instead of Replace?

Many older buildings face the same dilemma: outdated HVAC equipment that still functions but no longer meets modern efficiency or comfort expectations. Full fan coil replacement often requires opening walls, modifying infrastructure, and relocating occupants. That creates logistical challenges and increases project costs quickly.

EnviroKIT avoids those issues by working within the existing footprint. The cabinet stays in place. Piping connections remain largely untouched. The retrofit process is faster and far less disruptive, making it ideal for occupied buildings. This approach is especially valuable in properties where downtime directly impacts revenue or resident satisfaction.

Lower Project Costs and Faster Payback

Budget concerns play a major role in retrofit decisions. EnviroKIT typically costs significantly less than full fan coil unit replacement when labor, demolition, and restoration are factored in.

Because installation time is reduced, contractors can complete more rooms per day and minimize labor hours. Building owners benefit from faster project schedules and a quicker return on investment through energy savings and reduced maintenance expenses. For large-scale retrofit projects, these cost advantages can add up quickly across dozens or even hundreds of units.

Improved Energy Efficiency with EC Motor Technology

One of the biggest performance upgrades in the EnviroKIT system is the use of electronically commutated motors. EC motors consume less power than traditional PSC motors and allow variable speed operation based on actual demand.

This translates into:

• Lower electrical consumption

• Reduced operating costs

• Improved airflow control

• Quieter system operation

In many applications, upgrading to EC motors alone can produce noticeable energy savings. When paired with updated controls and optimized airflow components, the overall system performance improves even further.

Sustainability Benefits That Matter

Sustainability is no longer just a marketing buzzword. Many building owners now have environmental goals tied to energy use, material waste, and long-term asset management.

EnviroKIT supports these goals by reusing existing fan coil cabinets instead of sending large amounts of metal and construction debris to landfills. Fewer materials are discarded, and fewer new materials are required for manufacturing and shipping.

The combination of reduced waste and lower ongoing energy consumption makes EnviroKIT a strong option for green building initiatives and retrofit sustainability programs.

Faster Installation and Less Disruption

One of the biggest advantages of EnviroKIT is how quickly projects can move compared to traditional replacements.

Shorter installation times mean less downtime, fewer scheduling headaches, and smoother project coordination. Because the cabinet stays in place, installers can focus on swapping internal components rather than performing structural modifications.

This is especially important in:

• Hotels where room availability impacts revenue

• Senior living communities where resident comfort is critical

• Multifamily housing with tight renovation schedules

• Healthcare facilities where disruption must be minimized

Proven Performance and Industry Recognition

IEC’s EnviroKIT solution has earned recognition within the HVAC industry for its innovation in retrofit applications. These awards highlight the real-world impact of upgrading existing equipment instead of relying solely on full replacement strategies.

For engineers and facility managers, this recognition adds confidence that the product has been tested, proven, and adopted across a wide range of building types.

Ideal Applications for EnviroKIT Retrofits

EnviroKIT is well suited for buildings that rely on vertical stack fan coil units and need performance upgrades without major construction. In these environments, efficiency improvements, noise reduction, and minimized disruption are all high priorities.

Common applications include:

• Hotels and hospitality properties

• Senior living and assisted care facilities

• Multifamily apartment buildings

• Hospitals and healthcare campuses

• Student housing and dormitories
