Extending the Lifespan of Mid-Life Fan Coil Units: The Benefits of Mold Encapsulant and Drain Pan Refurbishment

Mold Encapsulant & Drain Pan Refurbishment

Fan Coil Mold Encapsulation

Mold encapsulant is a special coating applied to the fiberglass insulation within the HVAC cabinet, particular attention is spent on where some mold growth has occurred or is likely to occur. It prevents mold spores from becoming airborne and inhibits further growth.


  • Improves Indoor Air Quality:

By sealing mold spores and preventing them from spreading through the air, mold encapsulants contribute to healthier indoor air. This is crucial for reducing respiratory issues and allergies among building occupants.

  • Prevents Mold Recurrence:

Encapsulants create a barrier that makes it difficult for mold to regrow on treated surfaces, reducing the need for frequent cleaning and prolongs the need for costly remediation.

  • Extends Equipment Life & Prevents Floods:

Preventing mold growth helps protect the structural integrity of the HVAC insulation and stops it from becoming brittle and ending up in your drain pan or hose and causing a costly flood.

Drain Pan Refurbishment

Drain pan refurbishment involves cleaning and repairing the condensate drain pan in an HVAC unit to ensure proper drainage, prevent water accumulation and harden any soft spots that could turn into an eventual hole for water to leak through.


  • Prevents Water Damage:

Refurbishing the drain pan ensures that it effectively collects and drains condensation away from the system. This prevents water overflow that can cause damage to the fan coil unit and surrounding areas.

  • Reduces Mold and Bacterial Growth:

A clean and properly functioning drain pan prevents standing water, which is a breeding ground for mold and bacteria. This helps maintain better air quality and a healthier environment.

  • Extends Equipment Lifespan:

By avoiding water damage and reducing the potential for mold growth, drain pan refurbishment helps extend the life of the fan coil system, reducing the need for costly repairs or replacements.

Mold Encapsulant & Drain Pan Refurbishment

Implementing mold encapsulant and drain pan refurbishment in a mid-life fan coil unit brings multiple benefits

  • Healthier Environment: Both practices significantly improve indoor air quality by controlling mold and bacteria growth.

  • Cost Savings: Preventing mold growth and water damage extends the lifespan of the system and reduces maintenance and repair costs over time.

By addressing these aspects, you can clearly convey the value and necessity of these maintenance practices to stakeholders or clients.

Implementing mold encapsulant and drain pan refurbishment as part of a comprehensive maintenance program can extend the lifespan of your fan coil unit by 5 to 10 years beyond the standard lifespan.

This maintenance program offers numerous benefits, including:

  • Healthier Environment: Controlling mold and bacteria growth improves indoor air quality.

  • Cost Savings: Preventing mold growth and water damage reduces maintenance and repair costs.
