For any safety emergency, prioritize evacuating your home and calling emergency services before contacting HVAC contractors.

What to Do While Waiting for Emergency Service

Protect your home and family while waiting for the technician:

• No Heat: Close off rooms, use space heaters safely, open cabinet doors near exterior pipes, let faucets drip slightly
• No AC: Close blinds, drink water, move to coolest rooms, check on vulnerable family members
• Water Leaking: Turn off water supply to HVAC if possible, place towels and buckets to contain water
• Strange Noises: Turn system off at thermostat and circuit breaker to prevent further damage
• Gas Smell: Evacuate immediately, call 911 and gas company from outside, don't operate electrical switches

Regular Service vs Emergency Service

Not every HVAC problem requires emergency service:

• Call Emergency Service If: No heat below 32°F, safety concerns (gas, CO, smoke), at-risk family members, risk of property damage, business operations affected
• Wait for Regular Service If: Mild weather, reduced but not absent heating/cooling, minor issues, non-urgent repairs, routine maintenance

• Annual Maintenance: Fall furnace tune-ups and spring AC service prevent 95% of breakdowns
• Regular Filter Changes: Monthly filter replacement during heavy use seasons
• Address Warning Signs: Strange noises, reduced performance, or unusual smells need prompt attention
• System Age Monitoring: Replace aging systems (15-20+ years) before they fail
