What Retrotec does
Retrotec, Inc. is a privately held manufacturer of building airtightness and duct leakage testing equipment, founded in 1980 and headquartered in Everson, Washington, operating as a subsidiary of Wohler Retrotec, Inc. The company's core products are blower door systems (models 300, 5100, 6100, 7100, and multi-fan 5210/5310 systems), duct testers (340x, 440x), and digital manometers (DM32X, Solo) used by energy auditors, HVAC contractors, building contractors, home inspectors, and fire/safety testers. Its proprietary technology includes the DM32X touchscreen digital gauge with WiFi and dual pressure channels, SmartCloth door panels, Electronic Speed Control (ESC) for fan motors, built-in accelerometer tip sensors, and guide fins that reduce wind sensitivity by 75%.
Retrotec generates revenue through one-time hardware sales across a price ladder from $85 accessories to $16,400 dual-fan commercial systems, software licenses and add-ons (FanTestic Lite bundled, FanTestic Pro at $325, USACE and other standards as add-ons), ISO17025-accredited calibration services, and online/in-person training courses. Distribution is primarily direct e-commerce through retrotec.com supplemented by a global reseller network, independent testers/trainers accessible via a store locator, and an EU office in Harfsen, Netherlands, serving European markets. Hardware is complemented by FanTestic reporting software supporting ASTM E-779, USACE, EN 13829, ISO 9972, ATTMA, and CGSB standards, the rCloud cloud-based test data management platform, and a separate training portal at training.retrotec.com.

Retrotec competitors and assessment
Company assessmentOthers
- ACUITY-branded HVAC test equipment vendors (e.g., Bacharach): Bacharach manufactures combustion, flue gas, and HVAC refrigerant leak detection instruments sold to HVAC contractors and technicians. Adjacent competitor for the HVAC contractor's instrument budget rather than a direct blower door rival.
- Wohler (parent group brands): Wohler Gruppe is the German parent group that includes Retrotec, Wohler inspection cameras (e.g., the Wohler VE 200 sold by Retrotec), and other building diagnostics brands. Adjacent because they share corporate parentage and complementary product lines rather than direct market competition.
Direct peers
- Infiltec: Infiltec designs and sells blower door systems for building airtightness testing, competing directly with Retrotec in residential and small commercial segments. Specializes in energy audit and weatherization contractor use cases.
- The Energy Conservatory: The Energy Conservatory manufactures the Minneapolis Blower Door and DucTester — direct competitors to Retrotec's core product lines. Serves the same energy auditor, HVAC contractor, and building performance professional customer base in residential and commercial airtightness testing.
- Blower Door GmbH: Blower Door GmbH (Germany/Europe) manufactures blower door measurement systems and offers MINcinfan and TEDDO fan models for airtightness testing. Direct peer in the European passive house and EN 13829 testing market where Retrotec also operates.
Broad incumbents
- TSI Incorporated: TSI manufactures precision measurement instruments including airflow, indoor air quality, and building performance test equipment. Competes with Retrotec in commercial airflow measurement and duct testing, with broader industrial and laboratory instrument reach.
- Dwyer Instruments: Dwyer Instruments manufactures a wide range of measurement and control instruments including manometers, flow meters, and pressure gauges used in HVAC and building applications. Overlaps with Retrotec's DM32X manometer product line.
- Testo: Testo is a global leader in portable measurement instrumentation for HVAC, combustion, and indoor air quality. Overlaps with Retrotec in HVAC airflow and duct measurement, and offers broader instrument portfolios that compete for technician wallet share.
Emerging players
- Fieldpiece Instruments: Fieldpiece designs HVAC diagnostic instruments for service technicians, including digital manometers and airflow tools. Competes at the HVAC contractor level for diagnostic instrument spend alongside Retrotec's duct and airflow testing portfolio.
- Kane International: Kane International manufactures combustion and flue gas analyzers plus HVAC measurement instruments. Strong UK/European presence in HVAC professional testing — overlapping with Retrotec's duct testing and airflow measurement products.
