Comprehensive Filter System Inspections in Corona, CA

Yes - cigarette and cigar residue is one of our most common post-purchase asks. Standard scope is a full duct cleaning plus indoor coil clean, sanitize, and a new HVAC filter, documented with photos so you can show the system was reset.

A musty smell usually traces to dust and organic debris on a damp evaporator coil; an animal smell usually traces to a rodent intrusion in crawlspace or mobile-home ductwork. We inspect both, remove any nest material, clean the runs, and sanitize the coil.

If dust returns within hours of cleaning, the system is likely pulling unfiltered attic or wall-cavity air through a leak or a panned-return shortcut (common in older homes). We pressurize the system, locate the leak, and recommend sealing or a proper return-drop install.
