Heating and cooling systems have a way of failing at the worst moment — the first 100°F heat index of the summer, the overnight low during a January freeze, the holiday weekend when everyone else is closed. When comfort and safety are on the line, you shouldn't have to wait until Monday.
We provide 24/7 emergency HVAC service across Kennesaw and Cobb County with stocked trucks and technicians who can diagnose fast under pressure. Whether it's a dead AC in a heat wave, a no-heat call during an ice storm, or a burning smell you don't want to sleep next to, we give you a straight arrival window and get to work.
What Counts as an HVAC Emergency
Not every issue needs a midnight visit, but these do — call us right away if you have:
- No cooling during a heat wave, especially with kids, seniors, or pets home
- No heat during a freeze or ice storm
- A burning, electrical, or gas smell from the system
- Water pouring from the indoor unit or a flooded drain pan
- Sparking, smoking, or repeated breaker trips at the equipment
- A frozen-solid AC that won't cool no matter what
- Any situation where the indoor temperature is becoming unsafe
How Our Emergency Response Works
A live conversation, safety guidance, and a technician on the way with the common parts.
- 1
You reach a real person
Call +1 (327) 210-5999 any hour and we assess the situation, give you safety steps you can take right now, and set an honest arrival window instead of a vague 'sometime today.'
- 2
Safety-first triage on arrival
We check for gas, electrical, and water hazards first — shutting things down safely if needed — then confirm the symptom and get to the diagnosis quickly.
- 3
Fast diagnosis & clear price
We find the fault and give you a written price before chargeable work, even at 2 a.m. You'll know the after-hours rate up front — no mystery charges added later.
- 4
Repair now, or a safe stopgap
We fix it on the spot when we can from our stocked trucks. If a part must be ordered, we make the system safe, give you a plan, and get you comfortable as soon as possible.
When to Call Now vs. Wait Until Morning
If the situation is a safety issue — a gas or burning smell, sparking, smoke, or water actively damaging your home — call immediately, day or night. The same goes for a total loss of heating or cooling when the weather is dangerous and vulnerable people are home.
If the system is limping but the house is still safe and comfortable, it's usually fine to wait for a next-day appointment and avoid the after-hours rate. When you call, we'll help you make that judgment honestly rather than pushing an emergency visit you don't need.
Prepared for Kennesaw's Extremes
Our weather runs to both ends — heat indexes over 100°F in summer and the occasional ice storm like the 2014 event that shut the region down. Both extremes send failures spiking at exactly the same time, when every HVAC company is slammed.
We stock our trucks with the parts that fail most under that stress — capacitors, contactors, igniters, motors — so a large share of emergency calls end with the system running again on the first visit, not a days-long wait for a part.
What Emergency HVAC Repair Costs in Kennesaw
Emergency repairs use the same underlying pricing as scheduled work — AC repairs commonly $150–$650, furnace repairs $130–$650 in the Atlanta-area context — with an after-hours or weekend rate on top for the off-hours response. These are ranges, not quotes.
We tell you the after-hours rate before we roll and give you a written price before starting the repair. You should never be surprised by the bill just because the failure happened at midnight.
What affects your price:
- Time of the call — overnight, weekend, or holiday rates apply
- The failed component and whether it's on the truck
- AC versus furnace versus heat pump diagnosis
- Severity — a safety hazard may need immediate stabilizing work
- Accessibility of the equipment in the dark or bad weather
