What air duct cleaning actually does (and why Lexington homes need it)

How to tell if a Lexington air duct cleaner is running a scam (watch for these warning signs)
Not all air duct cleaning companies are equal. Scammers often target first-time homeowners with these tactics: - No free inspection. Reputable crews like ours always check your system first, no charge. If a company skips this step, walk away. - High-pressure sales. Avoid crews who demand same-day service or guilt you into ‘limited-time offers.’ A good technician will schedule based on your needs. - No license or insurance. Massachusetts requires air duct cleaners to be licensed through the Board of Building Regulations and Standards. Ask to see proof before hiring. /news/lexington-air-duct-cleaning-licensed-insured/ - Vague pricing. A legitimate quote should break down costs by duct length, system type, and services (e.g., mold remediation). If they say ‘$300 flat,’ ask what’s included. Lexington’s older homes near the Minuteman Bikeway often have hidden ductwork, so insist on a thorough inspection. /services/ You can also review reach us for a written quote.
When to clean your air ducts in Lexington (seasonal timing matters)
The best time for air duct cleaning in Lexington depends on your system’s condition and local climate: - Spring (April–May): Ideal for first-time cleanings. Humidity rises in summer, so a clean system prevents mold growth. Schedule before school starts if you have kids with allergies. - Fall (September–October): Critical for older homes. After summer humidity, ducts may harbor mold or mildew. Clean before sealing windows for winter to improve efficiency. - After renovations or pest infestations: If you’ve had work done near your HVAC (e.g., a basement remodel) or noticed rodents in your attic, debris likely entered the ducts. /blog/lexington-air-duct-installation-guide/ Avoid cleaning during extreme cold (January–February). Frozen pipes or tight schedules can delay service. /blog/best-time-for-air-duct-cleaning-lexington/ Take a look at our crew and certifications.

Why does my Lexington air duct cleaning company want to inspect my HVAC first?
