Blower doors
Fan, frame and panel systems used to measure building envelope leakage.
Energy and HERS testing
Used HERS and energy testing equipment for field work.
We look for blower doors, duct leakage testers, digital gauges and ventilation flow meters. We sell field instruments, not HERS ratings. Equipment moves quickly, so current availability is always on our eBay store.
Every instrument graded. Every instrument guaranteed.
Graded 1 through 4. Tested. Model and serial number on the packing list. 100% Return Guarantee.
What we buy and sell
Tools for the tests that matter.
The instrument type matters more than the name on the case. These are tools we seek out, not a list of what is in stock today.
Duct leakage testers
Duct testing fans, rings or plates and accessories for measuring duct airtightness.
Digital gauges
Two channel pressure and flow gauges used with blower doors and duct testers.
Pressure probes and hoses
Probe, hose and static tap kits for zone, attic and combustion appliance zone measurements.
Ventilation flow meters
Flow hoods, powered flow hoods and flow grids for mechanical ventilation airflow.
Retrotec, TEC and Oriflow are some names we encounter. We consider suitable instruments from other makers too. The brand does not determine whether we are interested.

The instruments, up close.
Examples of the kinds of energy testing instruments we buy and list. Current availability and pricing are always on our eBay store.
Blower door
A fan, frame and panel system for envelope leakage, shown here as a Minneapolis blower door.
Duct leakage tester
A duct testing fan with flow rings, gauge and flex duct, shown here as a Retrotec kit.
Digital gauge
A two channel pressure and flow gauge in its case, shown here as a TEC DG gauge.
The units shown are examples of the types we look for, not a promise of stock. We buy and list energy testing instruments from many makers.
What a working kit needs
Know what comes with the test.
HERS field testing uses blower doors for envelope leakage, duct testers for duct leakage and flow meters for ventilation. A working kit depends on its accessories as much as its main instrument. Each eBay listing states what is included and how it tested.
- Fan, frame, panel and gauge identified for a blower door kit
- Fan, rings or plate, gauge and tubing identified for a duct tester
- Pressure probes, hoses and fittings accounted for
- Accessories and missing pieces named in the listing
- Calibration documentation included only when specified
Every instrument graded. Every instrument guaranteed.
Graded 1 through 4. Tested. Model and serial number on the packing list. 100% Return Guarantee.
