What should Twin Falls homeowners ask before hiring a "HVAC" contractor?
- Is duct cleaning actually necessary, or is it always upsell?
- Necessary after rodent infestation, post-renovation construction dust, visible mold growth, or 10+ years since last cleaning in a high-pollen or dusty area. Skip "annual cleaning" recommendations — the NADCA 2025 ACR Standard explicitly notes routine annual cleaning isn't evidence-supported.
- How do I avoid the "$99 whole-home duct cleaning" scam shops?
- Ask for NADCA certification, a written scope that itemizes supply + return + main trunk, and confirmation they use source-removal (vacuum-out) rather than blow-and-go fogging. The $99 ads almost always upsell to $800+ on-site for "mold treatment" the home doesn't need.
- How can homeowners improve indoor air quality during Twin Falls' dusty summers?
- Start with higher‑efficiency filters rated for the system and schedule duct inspections if air carries persistent dust. Consider whole‑home filtration upgrades or UV air cleaners. Request a written plan listing expected benefits and maintenance intervals from the contractor.
