How quickly can a Lewiston HVAC crew arrive when the heat or cold hits?
- 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.
- When should Lewiston homeowners schedule duct cleaning or indoor-air-quality service?
- Schedule duct cleaning if occupants notice persistent dust, allergy symptoms, or after major indoor renovations. For Lewiston, consider IAQ service before winter when closed homes concentrate dust and pollutants.
- How should homeowners prepare HVAC equipment for Lewiston's warm, dry summers?
- Start with a spring inspection and coil cleaning to remove dust and pollen. Change filters and check refrigerant levels. Regular maintenance helps maintain cooling capacity in Lewiston's dry, dusty summer conditions.
