Air Balancing Services
Precision airflow measurement and calibration for every room in your home or building. NCI-certified, 28 years proven. Las Vegas’s air balancing specialists.
Air balancing is the core service that built Constant Air Balancing and Services over 28 years. It is the process of testing and adjusting your HVAC system so every room receives exactly the right amount of conditioned air. When your system is out of balance, some rooms are too hot, others too cold, and your equipment works harder than it should, driving up energy bills and shortening system life.
Our NCI-certified technicians use calibrated flow hoods, digital manometers, and temperature sensors to measure airflow at every supply and return register in your home or building. This is precision work, not guesswork. We identify exactly where air is being over-delivered, under-delivered, or lost through duct leaks, then make targeted adjustments to bring your entire system into balance.
In Las Vegas, where summer temperatures regularly exceed 115 degrees, air balancing is not optional, it is essential. Two-story homes in Summerlin and Henderson commonly suffer from second-floor overheating that most HVAC companies misdiagnose as an undersized system. We have fixed thousands of these problems with air balancing alone, saving homeowners from unnecessary equipment replacements.
Whether you have hot and cold spots, rooms that never feel comfortable, high energy bills, or a system that runs constantly without delivering results, air balancing analysis will pinpoint the exact cause. We serve residential, commercial and commercial clients across all of Clark County. Call (702) 840-5163 to schedule your diagnostic.
System Documentation
We begin by documenting your HVAC equipment specifications, ductwork configuration, register locations, and thermostat settings. If original design documents are available, we review them to establish target airflow values for each room.
Total System Airflow Test
Using calibrated instruments at the air handler, we measure total system airflow in CFM and compare it to the equipment rated capacity. This baseline tells us immediately whether the system has upstream restrictions limiting performance.
Register-by-Register Testing
Every supply register and return grille in the building is tested individually with a calibrated flow hood. We document the actual CFM at each location and calculate the deviation from design requirements.
Static Pressure Mapping
We measure static pressure at the supply plenum, return plenum, across the filter, and across the evaporator coil. High pressure readings indicate restrictions that steal airflow before it reaches your rooms.
Data Analysis and Report
All measurements are compiled into a comprehensive report showing room-by-room airflow data, pressure readings, temperature differentials, and specific recommendations for achieving optimal balance throughout your system.
NCI-Certified Accuracy
Our flow hoods and manometers are calibrated to NCI standards. Every measurement is precise, repeatable, and documented, not projected or approximated.
Desert Climate Expertise
Las Vegas HVAC systems face extreme thermal loads that amplify imbalances. We understand how desert conditions affect duct performance and airflow distribution.
Diagnostic Before Sales
We measure first, recommend second. Our analysis identifies the real problem, which may be a simple damper adjustment rather than the full system replacement another company quoted you.
Air balancing is the niche most HVAC companies skip, and it is the reason your back bedroom is ten degrees warmer than the living room. Balancing is testing and adjusting the airflow at every register so each room gets the air it was designed to get. It is not a guess at the damper, it is a measured number at the grille.
We pull airflow readings with a flow hood at every supply and return, then set dampers to hit the design target for each room. Every change we make gets a before and after reading. A typical home has rooms running 40 to 90 percent of their target before we touch it. After balancing, they land within range and the whole system stops fighting itself.
Because the equipment is no longer straining to overcool one zone to reach another, you usually see the power bill ease off too. Browse balancing jobs we have completed in the gallery.
Our upstairs was always boiling while the downstairs froze. They measured every vent, adjusted the dampers, and now the whole house holds the same temperature. I did not even know air balancing was a thing until a friend pointed me to Chris.
