Signs You Need Emergency HVAC Service
Not every HVAC issue can wait for a scheduled appointment. Here are signs of an emergency.
- No heat in winter
- No cooling in extreme heat
- Burning smell from vents
- Strange grinding or banging noises
- Water leaking near the furnace or AC
- Carbon monoxide alarm sounding
- Repeated system shutdowns
- Sparks or an electrical smell
- Total system failure
If you notice any of these signs, shut down the unit if it’s safe to do so and call our team right away.
Our 24/7 Emergency HVAC Repair Process
We keep our emergency process simple so you know exactly what to expect. When you call D & G Mechanical, you speak directly with our team, not an answering service that leaves you waiting. We gather details about your system and symptoms so we can arrive prepared with the right tools and parts on hand.
Once on site, our technicians perform a full diagnostic to identify the root cause rather than apply a temporary fix. We service all makes and models of furnaces, air conditioners, heat pumps, and boilers, so no matter what brand sits in your mechanical room, we know how to work on it. We walk you through what we found and what it will take to fix it before any work begins.
From there, we complete the repair as quickly as safety and quality allow. Our goal is always to restore comfort in a single visit whenever possible, and we stand behind every repair with honest workmanship built on 35 years of experience in this community.
HVAC Emergencies We Respond To
Our team is equipped to handle a wide range of urgent HVAC situations across residential, commercial, and industrial properties. We respond to furnace breakdowns during cold snaps, air conditioning failures during heat advisories, and heat pump malfunctions that leave a home without reliable temperature control. Boiler emergencies, including leaks and pressure issues, are also part of our regular emergency workload.
We also handle electrical and control failures within HVAC systems, refrigerant leaks, frozen coils, and ductwork damage that affects airflow throughout a building. Commercial and industrial clients rely on us for emergency service for rooftop units, packaged systems, and custom sheet-metal ductwork, since downtime in these settings can affect an entire business.
How to Stay Safe Until Help Arrives
While you wait for our team to arrive, there are a few steps you can take to help protect your home and family. If you smell gas or hear your carbon monoxide alarm, leave the property immediately and call emergency services before contacting us. For non-gas-related issues, turning off the unit at the thermostat or breaker can prevent further damage.
Keep the area around your furnace or air conditioner clear so our technician has room to work once they arrive. Small steps like these help keep everyone safe and can speed up the repair process once our team is on site.
