      • Supply Duct Location, Surface Area and R-factor
    • Air Conditioner Measures
      • Improved Refrigerant Charge
      • Installation of TXV
      • Adequate Air Flow
      • Air Handler Fan Watt Draw (Also requires
        Portable Watt Meter)
      • High EER
      •  Maximum Cooling Capacity
    • Building Envelop Measures
      • Building Envelope Sealing
      • High Quality Insulation Installation
  • Utility Programs
    • Air flow and Refrigerant Charge
    • Any additional programs similar to CA Title 24 as listed above
  • EPA Energy Star field verification for New ENERGY STAR® Residential Air-Source Heat Pumps and Central Air Conditioners (Projected to be effective March 2006.
  • California Building Performance Contractors Association and U.S. EPA Home Performance with Energy Star Program for existing homes.

Duct Blaster®

  • A lightweight Duct Blaster fan weighs just 7 pounds, but delivers enough air flow (an amazing 1,500 CFM) to test even the leakiest of duct systems
  • Quick and accurate air tightness measurements from 20 - 1,500 CFM. Compatible for both pressurization and depressurization testing. Compatible for both pressurization and depressurization testing.
  • The Duct Blaster can be easily used in new construction applications where a Blower Door can't be used (e.g. before sheet rock is installed).
  • The Duct Blaster can also be used as a powered flow hood to accurately measure air flows through the air handler fan, registers and grilles, and exhaust fans.
  • It incorporates a variable fan speed control (solid state) available for both 110V and 220V models and a data collection module for communication with and control by the laptop.
  • Includes a padded nylon carrying case with shoulder strap.

TrueFlow® Air Handler Flow Meter


  • Designed to provide a simple and accurate measurement of airflow through residential air handlers.
  • The TrueFlow Meter temporarily replaces the filter in the air handler distribution system during the airflow measurement process.
  • If the filter location is directly adjacent to the air handler, the TrueFlow Meter will measure the total air handler flow.
  • If the filter is located remotely at a central return, the TrueFlow Meter will measure airflow through the central return.

Blower Door®

  • Our Blower Door facilitates tests to gauge the air tightness levels of building envelopes.
  • It is utilized to diagnose and demonstrate air leakage problems, estimate natural infiltration rates, estimate efficiency losses from that air leakage, and to certify construction integrity.
  • The Blower Door enables precise, stable flow measurements without the need for gauge dampening.
  • Quick and accurate flow measurements from 30 to 6,300 CFM. It consists of a lightweight, rugged injection molded fan housing with and a variable fan speed control (solid state) in both 110V/60 Hz and 220V/50 Hz models (CE labeling available for 220V model) as well as a data collection module for communication with and control by the eScan laptop.


  • Digital pressure and flow gauge is the latest instrumentation option for the Model 3 Blower Door.
  • The DG-700 contains 2 precision pressure sensors which provide simultaneous display of both building pressure and Blower Door fan flow readings.
  • It's specialized "Baseline" and "CFM @50" features makes it extremely easy to get quick and accurate airtightness test results.
  • In addition, the DG-700 can be used along with a laptop computer and specialized TEC software to conduct fully automated Blower Door tests.
