Dryer Vent Cleaning: Do You Need Post-Cleaning Services?
When a professional cleans your dryer vent system, they should perform a thorough inspection, remove any built-up lint and debris, and check that all parts are secure and functioning properly. But some companies also offer add-on “post-cleaning services” like chemical treatments, coatings and filters. Here’s what to know about these services:
- Anti-microbial spray: Some companies apply an anti-microbial spray within the vent system after cleaning to supposedly discourage future mold and mildew growth. However, studies show these sprays have limited effectiveness over time due to degradation.
- Coatings: Some contractors apply moisture-resistant or smooth coatings inside vents that are claimed to improve airflow and resist corrosion. However, independent research suggests these coatings offers little benefit and can become brittle or deteriorate.
- Filters: Replaceable interior filters are offered that snap into the vent to capture more lint as clothes are dried. While they may catch some extra lint, there is debate as to whether they actually improve airflow or extend time between cleanings.
- Odor removers: Chemical odor neutralizers or absorbers are applied inside vents that claim to rid the system of musty or mildew smells. However, these products often have a limited lifespan and smells may return.
- Warranty: Many companies try to sell longer warranties as a post-cleaning service. But proper regular vent cleaning and general maintenance is usually more important than an extended warranty.
In summary, while post-cleaning services may sound beneficial, there is limited evidence they actually provide long-term value. Proper cleaning and inspection of your entire dryer vent system on a regular basis is still the most important task. Simply ask contractors to thoroughly clean your vents and ducting and thoroughly inspect for any necessary repairs. Opt for add-on services only if you determine they offer real value for your individual needs.
