Testing, Adjusting, and Balancing (TAB) for Commercial HVAC Systems
Precision airflow isn’t optional in commercial buildings — it’s essential for comfort, efficiency, and code compliance. At SWAN Electric, Plumbing, Heating & Air, our certified technicians provide expert Testing, Adjusting, and Balancing (TAB) services for commercial HVAC systems across the Dallas-Fort Worth metroplex.
We use calibrated instruments to measure system performance, diagnose airflow inconsistencies, and make targeted adjustments that restore balance to your building. If your facility has hot and cold spots, poor ventilation, or unexplained energy spikes — you may need TAB services.
What Is TAB in HVAC?
TAB is a process that ensures your HVAC system delivers the right amount of airflow to each space based on its design. It includes:
- Testing: Measuring airflow, temperature, pressure, and system performance.
- Adjusting: Calibrating dampers, fan speeds, valves, and thermostats.
- Balancing: Distributing airflow evenly across zones to meet design specifications.
Whether you’re managing an office building, retail plaza, medical facility, or school — proper balancing protects equipment, enhances comfort, and reduces utility costs.
Signs Your Building Needs Testing and Balancing:
- Uneven heating or cooling across rooms or floors
- Drafts or stagnant air in certain zones
- HVAC system running constantly without maintaining temperature
- Employees or tenants frequently adjusting thermostats
- Rising energy bills without an obvious cause

SWAN Electric, Plumbing, Heating & Air offers proactive, customized preventative maintenance programs for commercial buildings across Dallas-Fort Worth that reduce breakdowns, improve energy efficiency, and extend system lifespan.
Our annual maintenance plans are tailored to your building’s size, equipment type, and usage — whether you manage a single retail space or a multi-floor office building with multiple air handlers and RTUs.

Our commercial HVAC tune-ups typically include:
- Inspection and cleaning of coils, blowers, and drain lines
- Checking refrigerant levels and pressure

Commercial Air Duct Cleaning
When was the last time your building’s ductwork was cleaned? For most commercial properties, the answer is too long ago. At SWAN Electric, Plumbing, Heating & Air, we offer thorough commercial air duct cleaning services that help improve indoor air quality, enhance HVAC performance, and reduce energy waste — all while meeting health and safety standards.
If you're managing an office, school, retail center, or medical facility, buildup in your ductwork could be affecting your air and your bottom line.
Why Clean Your Commercial Ducts?
Over time, air ducts accumulate:
- Dust, dirt, and allergens
- Mold spores and microbial growth
- Construction debris and insulation particles
- Odors from tenants or industrial processes
This buildup leads to poor airflow, higher utility bills, and more strain on your HVAC system — especially in high-traffic or older buildings.
Our Duct Cleaning Process Includes:
- HEPA-filtered vacuum extraction to capture fine particulates
- Agitation and brushing to loosen buildup on interior duct walls
- Sanitizing mist treatments (available upon request)
- Before-and-after system performance reviews
- Service with minimal disruption to tenants or business operations
Ideal For:
- Buildings with recent construction, renovations, or water damage
- Facilities where tenants report musty smells or allergy symptoms
- High-occupancy spaces with shared airflow (e.g., coworking spaces, gyms)
Commercial Air Handler Repair and Replacement
Your air handler is the backbone of your HVAC system — when it fails, airflow across your entire building suffers. At SWAN Electric, Plumbing, Heating & Air, we provide expert air handler repair and replacement services for commercial buildings of all sizes across the Dallas-Fort Worth area.
From standalone units to integrated systems with VAV boxes and rooftop setups, our team is trained to diagnose and repair issues fast — and when replacement makes more financial sense, we’ll guide you through every step of the upgrade.
Common Signs Your Air Handler Needs Repair:
- Inconsistent airflow or total loss of airflow in certain areas
- Loud rattling, grinding, or banging noises from the unit
- Air smells musty or stagnant
- Fan motor failures or frequent capacitor burnouts
- Poor humidity control, even when AC or heat is running
We service all major brands and configurations, including custom commercial air handler units (AHUs), rooftop units (RTUs), and multi-zone systems.
When Is It Time to Replace the Air Handler?
If your air handler is:
- Over 15 years old
- Causing repeated outages or comfort issues
- Driving up energy costs
- Leaking, rusted, or cracked
… a replacement may offer better ROI than continued repairs. We’ll evaluate the system, recommend energy-efficient models, and coordinate installation with minimal disruption to your business.
