I’m looking for some advice from fellow landlords, property managers, or DIYers on cleaning out HVAC ventilation and air ducts.
My previous tenant wasn't the cleanest, and the property left behind a pretty strong dog smell. Before I rent the place out to a new tenant, I want to make sure the entire air ventilation system is thoroughly cleaned and odor-free.
For those who have tackled pet odor in air systems yourselves:
• DIY Cleaning Methods: Are there effective ways to clean and sanitize the accessible ducts yourself (e.g., using specialized vacuum attachments, foggers, or specific cleaning solutions)?
• Odor Elimination: What products actually break down embedded pet dander and oils inside the system rather than just masking the smell? (e.g., enzymatic sprays, chlorine dioxide, ozone machines)?
• Filter & Register Care: Besides changing the HVAC filter to a high-MERV or carbon filter and washing the vent covers, are there key areas inside the return/supply vents that people often overlook?
• DIY vs. Professional: At what point is a DIY job not enough, and when should I bite the bullet and hire a professional air duct cleaning service?
Any product recommendations, step-by-step tips, or cautionary advice would be greatly appreciated!
