Accepted Answer

Every Indoor Air Quality listing undergoes verification of state contractor license, general liability insurance (minimum $1M coverage), workers' compensation, and bonding where applicable.

Authoritative Indoor Air Quality listings should display: active state contractor license number, current liability insurance certificate, workers' compensation coverage, BBB accreditation, and trade-specific certifications (e.g. NATE for HVAC, NARI for remodeling, NRCA for roofing). DirJournal lists verified credentials in the Technical Specifications tab.

Question 3

How do I evaluate quotes from Indoor Air Quality contractors?

Accepted Answer

Get a minimum of three written quotes, each itemized for materials, labor, permits, and timeline. Be wary of: contractors who demand more than 30% upfront, cash-only discount offers, refusal to pull permits, lack of local references, or quotes significantly below market. DirJournal listings disclose payment policies and pricing transparency.

DirJournal listings indicate which contractors are permit-experienced and include permit costs in quotes.

Question 5

What warranty coverage should I expect from Indoor Air Quality providers?

Standard warranties include: workmanship warranty (typically 1–2 years from contractor), manufacturer warranty on materials (varies by product, often 10–25 years for major systems), and any extended warranty options offered. Reputable Indoor Air Quality contractors provide warranty terms in writing as part of the contract. DirJournal listings disclose standard warranty coverage where available.
