What Is HVAC Restoration?
FSR’s HVAC restoration program renews and modernizes aging air-handling units so they operate like new—without the cost, disruption, or waste of full system replacement. Our approach targets the key components that most impact airflow, energy efficiency, hygiene, and occupant comfort.
Did You Know?
An EPA study found that just
3/16" of debris across a coil can reduce efficiency by
~21%.
What HVAC Restoration Involves
Comprehensive, phased restoration tailored to each AHU
Each HVAC restoration project is structured to restore airflow, improve energy performance, and eliminate hygiene concerns across the entire air-handling unit.
- Deep steam cleaning of coils and interior surfaces to restore heat transfer efficiency.
- Corrosion-resistant antimicrobial coatings applied after surface preparation and priming.
- Seamless drain pan coatings to eliminate leaks, pooling water, and microbial growth.
- Closed-cell, fiber-free insulation upgrades that improve hygiene and longevity.
- Fan array modernization to enhance redundancy, reduce energy usage, and improve control.
Our Proven 6-Step HVAC Restoration Process
A structured, engineering-driven workflow designed to restore AHU performance with minimal disruption to facility operations.
Assessment & Diagnostics
A detailed inspection evaluates unit condition, airflow performance, corrosion, microbial contamination, and IAQ indicators. This baseline defines which restoration steps are needed.
Project Planning & Phasing
Customized scheduling minimizes disruption—often performed at night or on weekends. FSR develops access routes, safety plans, and phased sequencing to maintain HVAC operation.
Preparation & System Access
Before restoration work begins, the team prepares the area, isolates components as needed, ensures proper airflow management, and sets safety and containment measures.
Execution of Scope
Field crews complete all restoration tasks using certified materials and upgraded components, with strict safety and quality controls throughout.
Commissioning & Validation
Post-work testing verifies improved airflow, temperature control, energy efficiency, and IAQ performance. FSR provides documentation, photos, and testing data for full transparency.
Monitoring & Warranty Support
FSR continues to support performance through periodic inspections, system monitoring, and access to Tremco’s extended warranty options to ensure long-term reliability.
Key Benefits of HVAC Restoration
- Reduces risk of major equipment failure and emergency downtime
- Preserves capital budgets by avoiding full AHU replacement
- Improves energy performance with more efficient airflow
- Supports sustainability goals with lower carbon impact
- Enhances occupant comfort and indoor air quality (IAQ)
- Enhances building value through greater reliability
Ideal for Buildings That Need Performance Without Full Replacement
- Structurally sound but underperforming AHUs
- Facilities with limited capital budgets or long equipment lead-times
- Sustainability-focused organizations reducing embodied carbon
- Facilities prioritizing IAQ and wellness (schools, hospitals, labs)
