Commercial HVAC Maintenance: A Facility Manager's Checklist

Protect tenants, comply with codes, and extend equipment life with a proactive maintenance program.

Commercial HVAC systems are tenants' silent partners. When they work, no one notices. When they don't, complaints flood in.

Quarterly: filter changes, coil inspection, condensate drain flush.

Semi-annual: blower wheel cleaning, belt and bearing inspection.

Annual: full duct inspection, sanitization, NADCA-grade cleaning every 3–5 years.

From visible dust to unexplained allergies, here are the warning signs every Rancho Palos Verdes homeowner should know.

The honest answer depends on your home, your family, and your HVAC system. Here's what we recommend.

Cleaner air, lower bills, longer HVAC life — but only when the job is done right.
