HVAC emergencies do not follow a schedule. When your heating or cooling system breaks down unexpectedly, First Class is ready to help with fast, professional emergency repair service. Call us and we will get a technician headed your way, because comfort emergencies do not wait.

Whether it is a furnace failure in January or an AC breakdown in August, we understand that comfort cannot wait. Greenville's summer temperatures regularly exceed 95 degrees Fahrenheit with dangerous heat index values, and winter cold snaps can push overnight lows into the teens. Both situations can be hazardous for young children, elderly family members, and pets. Getting your system back online quickly is not just about comfort; it is about safety.

We serve Greenville, Simpsonville, Mauldin, Greer, Taylors, Spartanburg, and surrounding areas with emergency HVAC repair services. Our trucks are stocked with common replacement parts including capacitors, contactors, ignitors, flame sensors, blower motors, and refrigerant, so we can fix many issues on the first visit without needing to order parts and return another day.

No overtime charges, no surprise fees. We charge the same flat-rate pricing for emergency calls as we do for scheduled appointments. You will know the cost before we begin any repair, even on a holiday weekend. This commitment to transparent pricing is a core part of who we are as a company.

Common emergency calls we handle include complete system failures (no heat or no cooling), gas furnace safety shutdowns, refrigerant leaks causing frozen coils, electrical failures, thermostat malfunctions, and unusual smells or sounds from HVAC equipment. If you smell gas or suspect a carbon monoxide leak, call 911 first, then call us to inspect and repair the system.

The best way to avoid HVAC emergencies is through regular preventive maintenance. Our Total Comfort Members receive priority scheduling even during peak emergency demand, which means shorter wait times during the busiest periods. Most of the emergency breakdowns we see are preventable with annual tune-ups that catch worn components before they fail.

When to Call for Emergency HVAC Service

Complete Loss of Heating or Cooling

If your system stops working entirely during extreme heat or cold, your family's safety and comfort are at risk. This qualifies as an emergency, especially for households with young children, elderly residents, or pets.

Gas Leak or Carbon Monoxide Detector Alert

If you smell gas near your furnace or your CO detector goes off, evacuate your home immediately and call 911. Then call us. We will inspect the system, identify the source, and make repairs before you restart your furnace.

Water Leaking from Your HVAC System

A significant water leak from your indoor unit can cause ceiling damage, mold growth, and electrical hazards. Shut off the system, place towels or a bucket under the leak, and call us for same-day repair.

Electrical Burning Smell from Your Unit

An acrid, electrical burning odor coming from your HVAC system could indicate a failing motor, damaged wiring, or an overheating component. Turn off the system at the breaker and call for immediate inspection.

Frozen Pipes or Risk of Burst Pipes

When heating fails during freezing weather, your home's plumbing is at risk. A burst pipe can cause tens of thousands of dollars in water damage. Restoring heat quickly is critical to protecting your home.

What it costs

$150–$1,500typical range

Our diagnostic visit does not change at night, on a weekend, or on a holiday. We do not charge overtime rates. A technician finds the actual fault and gives you a flat-rate price before any work starts. The repair itself is priced separately, and most AC repairs run $150 to $1,500.

These are our own prices, not a national average. They are typical, not caps: size, efficiency tier, and access move the number. Your flat-rate quote comes before any work starts, and estimates on replacements are free.

Emergency HVAC FAQ

No. We charge the same flat-rate pricing for emergency service calls as we do for scheduled appointments. No overtime charges, no holiday surcharges, no surprise fees. You will know the exact cost before we begin any work.

Response times depend on current demand and your location, but we strive to reach most Greenville metro area homes within 60 to 90 minutes for emergency calls. Our office is located on Market Point Dr in Greenville, putting us centrally in our service area. We will give you an honest ETA when you call.

If your AC fails in summer: close blinds to block solar heat, use fans to circulate air, and stay hydrated. If your heat fails in winter: bundle up with blankets, close doors to unused rooms to concentrate body heat, and use a space heater safely (never leave unattended). If you smell gas: leave the house immediately, do not use electrical switches, and call 911 before calling us.

A brief dusty smell when your furnace first starts in fall is normal. However, persistent burning smells, metallic odors, or the smell of rotten eggs (indicating a gas leak) are all reasons to shut off your system immediately and call for service. Never ignore unusual odors from your HVAC system, they can indicate serious safety hazards including carbon monoxide risks.

Yes. The Department of Energy and HVAC industry data consistently show that regularly maintained systems experience 95% fewer emergency failures than neglected ones. Most of the emergency repairs we perform involve components that showed early warning signs during maintenance inspections. Our Total Comfort Membership covers both seasonal tune-ups and provides priority emergency scheduling.
