Best Indoor Air Quality Contractors in Lake Oswego, OR
What to look for in Indoor Air Quality Services in Lake Oswego
Indoor air quality is a category, not a single product — whole-home air purifiers (HEPA, electrostatic), UV-C germicidal lights, humidifiers, dehumidifiers, ERV/HRV ventilation systems, duct testing for leakage. The pros worth hiring publish their service mix and either install in-house or partner with a specific OEM (Aprilaire, Honeywell, Carrier IAQ).
- IAQ specialization. Provider lists indoor air quality services as a distinct line — not just "we change filters". Looks for: whole-home purifier installs, UV-C work, humidifier/dehumidifier installs, ERV/HRV ventilation.
- Duct testing capability. Duct leakage testing (blower-door or duct-blaster) is the diagnostic step that separates IAQ pros from filter-change shops. Often tied to building-performance certifications (BPI, RESNET).
- Indoor air quality advertised. Explicit IAQ marketing on the provider's site — products carried, brands installed, certifications mentioned.
Verify before you book
- Specific equipment carried (Aprilaire vs Honeywell vs Carrier IAQ vs IQAir) — ask before quoting.
- Active BPI or RESNET certification — we accept self-claimed if mentioned.
- Whether "UV-C" claims include the upper-room or in-duct variants — different installs, different effectiveness.
