Attic insulation vs duct cleaning
Attic insulation vs duct cleaning: both promise lower energy bills — compare when each actually saves money and which to do first.
Attic insulation (blown-in cellulose or fiberglass, spray foam, or batt insulation) costs $1,500–$5,000 for an average home and can reduce heating and cooling costs by 10–50% depending on the existing insulation level. The Department of Energy estimates that proper attic insulation (R-38 to R-60 depending on climate zone) is one of the highest-ROI energy upgrades. Air duct cleaning involves removing dust, debris, and microbial growth from HVAC ductwork using specialized vacuum and agitation equipment — a typical whole-home cleaning costs $300–$600. While duct cleaning improves indoor air quality, the EPA notes it hasn't been shown to prevent health problems or significantly reduce energy bills in most homes. For energy savings, attic insulation almost always delivers more ROI; for air quality, duct cleaning helps when ducts are visibly contaminated.

|---|---|---|
| Best for | Choose attic insulation when your energy bills are high, rooms feel hot in summer or cold in winter despite the HVAC running, or an energy audit reveals insufficient insulation — this is typically the single best energy-saving upgrade. | Choose duct cleaning when you notice visible mold growth inside ducts, excessive dust coming from registers, unexplained musty odors when the HVAC runs, or after a major renovation that generated heavy dust. |
