Applied mastic sealing for all duct joints and connections, the most durable sealing method for Georgetown's attic conditions.
Seal duct boots at registers where leakage directly into walls or ceilings causes significant energy loss.
Airflow Balancing
Measure and balance air distribution across all supply and return vents for even comfort throughout the home.
Comprehensive whole-house airflow evaluation and adjustment, dampers, registers, and duct sizing evaluated.
Balance airflow to specific problem rooms that receive too much or too little conditioned air.
Adjust zone dampers and control settings for homes with zoning systems to improve comfort and efficiency.
Full optimization of multi-zone airflow systems, control logic, damper travel, and zone sizing.
Optimize how conditioned air is distributed throughout the duct system for efficiency and comfort.
Improve overall air movement in the home through duct, register, and equipment adjustments.
Undersized return air is the most overlooked duct problem, we measure and correct return air flow.
Expand or add return air drops to improve system static pressure and airflow in homes with insufficient return capacity.
Dampers & Registers
Install manual balancing dampers in branch ducts to control airflow to specific zones or rooms.
Repair or replace motorized zone dampers that are stuck open, stuck closed, or not responding to controls.
Replace damaged, rusted, or improperly sized floor registers and diffusers.
Replace ceiling supply and return grilles with correct sizing and airflow direction for your room layout.
Install transfer grilles to improve pressure equalization and airflow between rooms with closed doors.
Install jump ducts above doorways or through walls to allow air pressure equalization between zones.
Redirect or baffle supply vents that blow directly on occupants or create drafty areas.
Measure and calibrate airflow from each vent against design specifications.
Ventilation & Testing
Repair ERVs, HRVs, exhaust fans, and dedicated ventilation systems.
Improve fresh air exchange and indoor air quality through targeted ventilation upgrades.
Measure system static pressure to identify duct restrictions causing equipment stress and efficiency loss.
Isolate duct sections from structure to eliminate vibration noise that transmits through walls and ceilings.
Install internal duct lining to absorb noise from high-velocity air movement in ducts near occupied spaces.
Duct Insulation & Protection
Install or replace duct insulation in Georgetown attics where heat gain from uninsulated ducts wastes significant energy.
Install vapor barriers to prevent condensation on cold supply ducts in Georgetown's humid summers.
Support or repair duct systems during crawlspace encapsulation projects.
Repair small-diameter high-velocity duct systems found in older homes and historic properties.
Measuring and Calibrating Every Vent
Vent output calibration is a precise, register-by-register comparison of measured airflow against the design specification for that specific vent, used when a homeowner or a previous inspection has raised concerns about whether the duct system is actually performing to its original design intent, or after a system component change, like a new blower motor or a filter upgrade, that could plausibly have changed system airflow overall. Unlike general balancing, which focuses on relative comfort between rooms, calibration is a documented measurement process that establishes exactly how each vent is performing against a specific numeric target.
We calculate the design airflow target for each register based on the room's Manual J load or, where original design documentation exists, the specified cubic feet per minute from the original system design. Using a flow hood, we measure actual output at every supply register and compare it against that target, documenting any registers performing significantly above or below spec. This process also captures total system airflow at the equipment, which we compare against the equipment's rated capacity, since a system that is calibrated correctly at the register level but shows overall airflow well below equipment rating points to a system-wide restriction, like a clogged filter or excessive static pressure, rather than a register-by-register balancing issue.
This service is useful for homeowners evaluating whether a system installed or serviced by a previous contractor was actually configured correctly, for verifying performance after a significant component change, and as part of pre-purchase due diligence when buying a Georgetown home with an HVAC system whose maintenance and installation history is uncertain. We provide a documented report showing measured versus target airflow at every register along with total system airflow, which gives a homeowner or their inspector an objective baseline rather than a subjective assessment of comfort. Calibration typically takes 3 to 4 hours for an average home and runs 300 to 600 dollars, and any deviations found from target can be addressed with balancing or damper adjustment as a follow-up if desired.
