HVAC Safety

Keeping Your Home Safe

HVAC systems are generally safe, but proper maintenance and awareness prevent potential hazards. Regular professional maintenance is the best way to ensure safe operation. Here's what every homeowner should know.

Carbon Monoxide Safety

CO is an odorless, colorless gas produced by gas furnaces. Exposure can be fatal.

• Install CO detectors: On every level, especially near bedrooms
• Annual inspections: Have gas furnaces inspected yearly
• Watch for symptoms: Headaches, dizziness, nausea, confusion
• Yellow pilot light: Should be blue; yellow indicates incomplete combustion
• If alarm sounds: Evacuate immediately, call 911, then call us

Signs of Potential CO Issues

• Yellow or flickering pilot light (should be blue)
• Soot or black streaks around furnace
• Excessive moisture on windows near furnace
• Burning or unusual odors
• Family members experiencing flu-like symptoms

Electrical Safety

HVAC systems use significant electrical power:

• Don't DIY electrical work: HVAC electrical requires professionals
• Check for worn wires: Report fraying or burn marks
• Tripping breakers: Frequent trips indicate a problem
• Keep area clear: No storage around indoor unit
• Use correct breakers: Never replace with higher amperage

Fire Prevention

• Change filters regularly: Clogged filters cause overheating
• Keep clearance: 3 feet around furnace and water heater
• No flammable storage: Nothing combustible near HVAC equipment
• Maintain exhaust vents: Keep clear of blockages
• Professional installation: Improper installation causes fires

Refrigerant Safety

AC refrigerant requires professional handling:

• Never attempt DIY: Refrigerant is a controlled substance
• Leaks are dangerous: Can displace oxygen in enclosed spaces
• Report hissing sounds: May indicate refrigerant leak
• EPA certified technicians: Only certified pros handle refrigerant

Safe Operation Tips

• Know your shutoffs: Learn where to cut power and gas
• Don't ignore strange smells: Burning odors mean stop and call
• Keep outdoor unit accessible: Technicians need emergency access
• Secure panels: Keep access doors closed during operation
• Use original parts: Non-OEM parts may be unsafe

When to Shut Off Your System

• Burning smell or visible smoke
• Sparking or electrical arcing
• Gas odor near furnace
• Water leaking onto electrical components
• Loud banging or grinding noises

Florida-Specific Safety Concerns

• Hurricane preparation: Know how to safely shut off systems before storms
• Flooding risks: Never operate HVAC after water exposure until inspected
• Lightning damage: Surge protectors help prevent electrical damage
• Mold growth: Florida humidity can cause mold in ducts and units
• Condensate overflow: Clogged drain lines can cause water damage and safety hazards

Emergency Procedures

• Gas smell: Don't flip switches, evacuate, and call 911 from outside
• CO alarm: Evacuate immediately, call 911, don't re-enter until cleared
• Electrical fire: Never use water, use appropriate extinguisher or evacuate
• Flooding: Stay away from equipment until power is disconnected by professionals

Child and Pet Safety

• Outdoor units: Keep children and pets away from outdoor equipment
• Vent covers: Ensure floor vents have secure covers
• Thermostat locks: Prevent curious hands from adjusting settings
• Air quality: Regular maintenance keeps indoor air safe for everyone

Professional Safety Inspections Include

• Heat exchanger crack inspection
• Gas line and connection checks
• Electrical component testing
• Carbon monoxide testing
• Combustion analysis
• Safety control verification
