SND Heating & Air Conditioning | Emergency HVAC Services in Kennesaw, GA

This is a common issue in our area during peak summer. Often, the problem is a failed capacitor, which is a critical component that helps your AC's compressor and fan motor start and run. Dirty evaporator coils, low refrigerant levels, or a malfunctioning compressor can also be culprits. Our technicians can quickly diagnose the specific cause and get your cool air flowing again.

We prioritize emergency calls, especially during heat advisories. Our goal is to have a technician dispatched to your Kennesaw home as soon as possible, often the same day you call. We understand that a broken AC isn't just an inconvenience; it's a health and safety concern for your family.

Warning signs include your AC unit humming but not starting, frequent circuit breaker trips, or the system shutting off randomly. While capacitors naturally wear out, regular professional maintenance can help spot a weakening capacitor before it fails completely. Our maintenance service includes checking these components to help you avoid a sudden breakdown on the hottest day of the year.
