When your home’s heating or cooling system fails unexpectedly, comfort can disappear in minutes — and waiting for regular business hours simply isn’t realistic. Sheet Metal Contractors Inc. delivers dependable residential emergency HVAC service at any hour, giving homeowners immediate access to skilled professionals who can restore comfort and safety quickly. As SMCI, we know that system failures often happen at the most inconvenient times, which is why we maintain a fully staffed 24-hour response team, ready day, night, weekends, and holidays, to bring your home back to a safe and comfortable temperature.

Expert 24-Hour Emergency HVAC Assistance

Extreme heat or cold can make an HVAC outage more than an inconvenience — it can become a health or safety concern. Our emergency response technicians are trained to diagnose residential HVAC failures efficiently, using advanced tools and well-stocked service vehicles to reduce delays and deliver fast results. Whether your system stops working entirely or you notice early signs of a serious issue, we provide reliable solutions designed to protect both your home and your family.

Common emergencies we handle include:

• No heat or no cooling situations
  
  
• Furnaces or air conditioners that won’t start
  
  
• Electrical problems, blown fuses, or tripped breakers
  
  
• Gas leaks or refrigerant leak concerns
  
  
• Frozen evaporator coils or overheating equipment
  
  
• Odd smells, loud noises, or rapid system cycling
  
  

Existing SMCI clients receive priority dispatch and direct access to our on-call technician, ensuring a faster response and clear communication before, during, and after the visit. Our goal is to arrive prepared, address the issue quickly, and restore safe operation as efficiently as possible.

Scheduled Residential Service & Non-Emergency Repairs

Some HVAC concerns, while important, do not require immediate after-hours response. For these situations, SMCI offers scheduled service during standard hours to handle repairs, adjustments, and routine upkeep. These appointments allow our technicians to evaluate system performance, complete preventive work, and resolve comfort concerns before they escalate into emergencies.

These scheduled services include:

• Routine maintenance and seasonal tune-ups
  
  
• Filter replacement and airflow optimization
  
  
• Thermostat, zoning, or control troubleshooting
  
  
• Energy-efficiency assessments and performance checks
  
  
• Duct repair, sealing, or replacement for improved airflow
  
  
• Scheduled part replacements and preventive repair work
  
  

By addressing minor issues early, homeowners enjoy improved reliability, reduced utility costs, and fewer stressful breakdowns during extreme weather. Our team helps keep systems running more efficiently, leading to better comfort year-round.
