The Hidden Problem

Why Your HVAC System Needs Assessment

Your heating and cooling system is the lungs of your building. When contaminated, it distributes pollutants to every room.

Continuous Circulation

HVAC systems run continuously, recirculating air 5-7 times per day. Any mold or contaminants in the system spread to every occupied space, magnifying exposure risks exponentially compared to localized contamination.

Out of Sight

Ductwork, plenums, and air handlers are hidden behind walls, above ceilings, and in mechanical rooms. Mold growth in these areas goes completely unnoticed until health symptoms or system failures demand investigation.

Ideal Growth Conditions

Condensation on cooling coils, temperature differentials in ductwork, and accumulated dust create perfect environments for mold colonization. Dark, humid conditions inside HVAC components accelerate growth year-round.

Thorough Inspection

Every Component Examined

Our assessment covers the complete HVAC system from intake to vent, identifying contamination at every potential point.

Supply & Return Ductwork

Visual inspection and borescope examination of duct interiors for mold growth, dust accumulation, moisture staining, and structural damage. Includes testing for air leaks that draw in contaminated air.

Evaporator Coils

Inspection of cooling coils for biofilm buildup, mold colonization, and adequate drainage. Dirty coils reduce efficiency and become active mold incubators due to constant condensation.

Air Filters & Filtration

Evaluation of filter condition, MERV rating adequacy, and proper installation. Poor filtration allows spores and particles to bypass capture and deposit throughout the system.

Condensate Pans & Drains

Examination of drain pans for proper slope, drainage function, and microbial growth. Standing water in pans breeds bacteria and mold that become aerosolized into supply air.

Air Handlers & Blowers

Inspection of blower motors, housings, and internal surfaces for dust loading and biological growth. Imbalanced or dirty blowers reduce airflow and can harbor extensive contamination.

Vents & Registers

Assessment of supply and return vents for dust accumulation, mold staining, and proper airflow balance. Blocked or contaminated vents compromise system performance and indoor air quality.

Humidifiers & Dehumidifiers

Evaluation of whole-house humidity control equipment for cleanliness and proper operation. Malfunctioning units can over-humidify spaces or introduce standing water into airflow.

Heat Exchangers

Inspection of heat exchangers for cracks, corrosion, and soot buildup that can compromise combustion safety and introduce contaminants into circulated air.

Outdoor Condensing Units

Assessment of exterior units for debris accumulation, proper clearance, and condensate management. Blocked units strain the system and can introduce outdoor contaminants.

Our Method

How Our Assessment Works

A systematic, multi-phase evaluation that leaves no component unchecked.

System History Review

We begin by reviewing maintenance records, previous issues, occupant health complaints, and system specifications to identify high-risk areas and focus our inspection.

Visual & Physical Inspection

Technicians examine all accessible components using flashlights, mirrors, and borescope cameras to document visible mold, moisture, dust loading, and mechanical condition.

Airflow & Performance Testing

We measure supply and return airflow, temperature differentials, static pressure, and humidity levels to identify performance issues that contribute to contamination.

Sampling & Lab Analysis

When indicated, we collect air and surface samples from ductwork and components for accredited laboratory analysis to identify specific contaminants and concentrations.

Common Issues

What We Typically Discover

HVAC systems accumulate a surprising variety of problems over time. Our assessments routinely uncover issues that property owners never suspected were affecting their air quality and system performance.

Active Mold Colonies

Cladosporium, Aspergillus, and Penicillium commonly colonize damp duct interiors and coil surfaces, releasing spores directly into occupied spaces.

Excessive Dust & Debris

Years of accumulated dust in ductwork restricts airflow, reduces efficiency by up to 40%, and provides organic material that supports microbial growth.

Moisture Intrusion

Leaky ductwork draws in humid attic or crawl space air, while poor drainage creates standing water that breeds bacteria and mold throughout the system.

Cross-Contamination

Leaky return ducts in contaminated areas like attics or crawl spaces pull mold spores and pollutants directly into the system and distribute them building-wide.

Timing

When to Schedule an HVAC Assessment

Certain events and conditions make professional assessment especially critical.

Before Buying a Property

HVAC contamination is invisible during standard home inspections. Assessment before purchase prevents inheriting costly hidden problems.

After Water Damage

Flooding, leaks, or high humidity events can introduce moisture into ductwork and air handlers, requiring immediate system evaluation.

Occupant Health Complaints

When building occupants experience symptoms that improve away from the property, the HVAC system is often the primary contamination source.

Routine Maintenance

Annual assessments catch developing issues before they become serious, similar to annual physical exams for your building's respiratory system.

Post-Construction

Renovation dust, debris, and moisture can infiltrate HVAC systems during construction. Assessment ensures systems weren't compromised.

After Mold Remediation

Verify that HVAC systems were properly protected during remediation and that no cross-contamination occurred during the process.

FAQ

HVAC Assessment Questions

Common questions about our HVAC inspection and testing services.

Most residential assessments require 2-3 hours, while commercial systems may take 4-6 hours depending on complexity and square footage. We schedule sufficient time to examine every component thoroughly without rushing. Large multi-zone systems or properties with extensive ductwork networks may require additional time, which we discuss during scheduling.

We need to cycle the system during testing to measure performance under normal operating conditions, but disruption is minimal. The system remains functional throughout most of the inspection. We coordinate with property managers for commercial buildings to minimize impact on occupants. Temporary shutdown of specific zones may occur briefly during airflow testing.

Absolutely. We assess HVAC systems in office buildings, schools, healthcare facilities, retail spaces, and industrial properties. Commercial assessments include rooftop units, chilled water systems, VAV boxes, and complex multi-zone configurations. We work around business hours and coordinate with facilities teams to ensure comprehensive coverage without operational disruption.

We provide both assessment and remediation services. Our assessment identifies exactly what cleaning or repairs are needed, and we can perform the work ourselves or provide specifications for your preferred contractor. This integrated approach ensures that identified problems are properly addressed according to the assessment findings, with post-remediation verification available.

We recommend annual assessments for residential systems and semi-annual assessments for commercial properties with high occupancy or sensitive populations like schools and healthcare facilities. Systems in humid climates, near construction zones, or with histories of water damage benefit from more frequent evaluation. Filter changes and basic maintenance should occur more regularly, but comprehensive component assessment annually catches developing issues early.
