What every building professional should know to protect people, property, and systems
Whether you’re maintaining a residential property, overseeing a commercial facility, or prepping a building for sale, HVAC systems deserve more safety attention than they often get. These systems quietly work behind the scenes—but if ignored, they can pose risks ranging from poor air quality to electrical hazards, fires, and even occupational injury.
Here are key safety recommendations to help professionals reduce risk and maintain compliance:
- Always Power Down Before Servicing
Before any inspection, cleaning, or repair, ensure that the power to the HVAC system is shut off at the breaker panel. This includes air handlers, furnaces, compressors, and thermostats. It’s a simple step—but one that prevents shocks, burns, or unintended fan activation.
- Use Proper PPE (Personal Protective Equipment)
Whether you’re cleaning ducts, replacing filters, or handling biological growth, technicians and maintenance personnel should wear:
- Gloves
- Safety goggles or face shields
- Respirators (especially when dealing with mold or contaminated insulation)
- Coveralls when working in dirty or confined spaces (attics, crawlspaces)
- Be Cautious of Airborne Contaminants
Disturbing dirty ductwork or HVAC components can release dust, allergens, mold spores, and even fiberglass particles into the air. Make sure technicians use HEPA-filtered vacuums and containment protocols to protect both workers and occupants.
- Monitor for Fire Hazards
- Dirty blower motors or clogged filters can lead to overheating.
- Electrical issues (exposed wiring, damaged insulation, loose connections) should be reported immediately.
- Dryer vent systems, especially in multi-unit buildings, should be regularly inspected and cleaned to reduce fire risk.
- Know Emergency Shut-Off Locations
Every property manager or facilities team should know where the HVAC system’s emergency shut-offs are located—whether it’s a rooftop unit, basement furnace, or wall-mounted split system. In an emergency, seconds matter.
- Maintain Filter & Coil Cleanliness
Clogged filters don’t just reduce airflow—they can put strain on motors and increase fire potential. Dirty evaporator or condenser coils can cause icing, flooding, or overheating. Add these to your routine inspection list.
- Document All Maintenance and Safety Checks
Keep records of inspections, filter changes, cleanings, and repairs. Not only does this support safety and compliance—it helps with warranty claims, building performance, and resale value.
