How long should a typical Gastonia hvac repair take, and who needs to be licensed for it?
- 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.
- Will duct cleaning or IAQ work help with Gastonia’s summer humidity and indoor mold risk?
- Targeted duct cleaning and whole‑home IAQ measures can reduce dust and biological load, which helps when humidity rises. Combine filtration upgrades with dehumidification and proper duct sealing for better results. Ask providers for test-based recommendations and for before/after photos of IAQ work on similar homes.
