Ensure Efficiency, Safety & Compliance for Your Commercial HVAC Systems

Proper ductwork is critical for maintaining indoor air quality, energy efficiency, and HVAC performance in commercial buildings. Maryland building codes and energy efficiency standards increasingly require professional duct testing to verify airtightness and system performance.

What is Commercial Duct Testing?

Commercial duct testing is a process that measures how much air is leaking from your HVAC duct system. Leaky ducts can cause:

  • Increased energy costs due to conditioned air escaping before reaching the intended space

  • Uneven temperature distribution across the building

  • Reduced HVAC lifespan due to increased system strain

  • Poor indoor air quality from dust, debris, and unconditioned air entering the ducts

During testing, certified technicians use specialized equipment like duct blasters and pressure gauges to evaluate duct leakage and airflow. Results are compared against industry standards and local building codes.

Why Duct Testing Matters in Maryland

Maryland commercial buildings fall under energy codes based on the International Energy Conservation Code (IECC), which mandates specific duct leakage limits for new construction and renovations.

  • Maximum leakage allowed: Typically ≤ 4% of fan airflow for new systems (per ACCA/ASHRAE standards and IECC guidelines)

  • Purpose: Ensure HVAC systems operate efficiently, safely, and provide consistent comfort

  • Local compliance: Testing can be required for LEED certification, energy audits, or local permitting

Commercial Duct Testing Process

  1. Preparation: All HVAC equipment is temporarily shut down, and duct openings are sealed as needed.

  2. Pressurization: A duct blaster is installed, and air is pumped into the system to measure leaks.

  3. Measurement: Technicians record leakage rates in CFM (cubic feet per minute) relative to system airflow.

  4. Analysis & Reporting: A detailed report identifies problem areas and recommends sealing solutions.

  5. Remediation & Retesting (if necessary): Duct leaks are sealed using mastic, tape, or aerosol sealing, followed by a retest to ensure compliance.

Benefits of Commercial Duct Testing

  • Energy Savings: Properly sealed ducts reduce wasted energy and lower utility costs.

  • Code Compliance: Meets Maryland’s building code and IECC standards for duct leakage.

  • Comfort & Performance: Ensures even temperature distribution and optimal HVAC operation.

  • Indoor Air Quality: Minimizes infiltration of dust, mold spores, and outdoor pollutants.
