The average cost to redo ductwork in a house typically ranges from $3,000 to $7,500, but this can vary significantly based on the home's size, system complexity, and materials. For a standard single-family home, the national average often falls between $4,500 and $5,500. Key factors influencing price include the home's square footage, the number of vents and returns needed, accessibility within walls and ceilings, and whether you choose flexible ducting or more durable sheet metal. Labor constitutes a major portion of the expense. It is crucial to get multiple detailed estimates from licensed HVAC contractors, as proper design and installation are critical for system efficiency, indoor air quality, and long-term performance.
The 2-foot rule is a critical guideline in HVAC ductwork design and installation. It states that the distance between the end of any flexible duct and a supply air register (the vent in your wall, floor, or ceiling) should be no more than two feet. This rule is essential because flexible duct, when not properly supported, can sag, kink, or compress. These restrictions severely impede airflow, reducing system efficiency, increasing energy costs, and creating uncomfortable hot or cold spots in a building. Adhering to this standard ensures optimal air delivery and system performance.

Homeowners insurance typically does not cover air duct replacement due to normal wear and tear, aging, or a lack of routine maintenance. Coverage is generally reserved for sudden and accidental damage caused by a covered peril listed in your policy. For example, if a fire, significant hail damage, or a fallen tree ruptures your ductwork, the resulting repair or replacement might be covered. However, if ducts need replacement because they are old, inefficient, or have deteriorated over time, that is considered a home maintenance responsibility. Always review your specific policy details and consult with your insurance agent to understand your coverage limits and exclusions, as these can vary significantly between providers.
Stanley Steemer is a well-known national franchise, but their pricing for air duct cleaning can vary significantly based on several factors. Typically, costs are influenced by the home's size, number of vents and returns, system accessibility, and the level of contamination. For a standard single-family home, you might expect a base price in the range of $300 to $500, though this can increase for larger properties or additional services like dryer vent cleaning. It's crucial to get a detailed, in-person or video inspection quote, as prices are not standardized. Always verify what the quoted price includes, such as sanitization or post-cleaning inspection, and compare with local, licensed HVAC specialists who may offer competitive rates and more personalized service.
