Tankless Water Heater Installation in Jacksonville, NC

We schedule a free, no-obligation visit to understand your hot water needs. Our technician measures your home’s layout, identifies existing water lines and gas lines, checks current gas pressure and capacity, documents venting routes, and asks about your hot water usage patterns and appliances.

We then calculate your peak simultaneous demand—if your shower, dishwasher, and washing machine run at the same time, what hot water flow (GPM) do you need? We then recommend the right model and capacity (Navien, Bradford White, or another trusted brand) at the efficiency level that matches your usage and budget.

We show you projected energy savings compared to your current tank system and discuss how financing spreads the cost over time. You’ll receive a detailed written estimate—equipment, labor, gas line work, venting, permitting, and disposal—before you commit.

Once you approve the estimate and sign the service agreement, we pull any required permits through the local building department—permit requirements vary by county and venting type (direct vent, power vent, or atmospheric)—and place the order with our supply partner for your new tankless unit.

We provide a lead time (usually 1–2 weeks), confirm the exact model and serial number, verify the warranty registration details, and confirm that delivery is scheduled for your installation date.

Our supply team inspects the unit on arrival to ensure it came damage-free, checking for shipping damage and verifying that all internal components are intact; if anything is wrong, we arrange an immediate replacement, never delaying your install. We also pre-verify venting compatibility and any special adapters or connectors your specific unit needs.

On the morning of installation, our crew arrives with all tools and materials. We carefully disconnect your old tank water heater—draining all water safely into buckets, disconnecting gas lines at the shutoff valve, disconnecting electrical connections, and disconnecting inlet and outlet water lines. We then remove the tank and dispose of it responsibly, separating salvageable metal and handling any hazardous components per environmental code.

We inspect the location where your tankless unit will mount—checking wall studs, existing framing, moisture barriers, and proximity to venting termination points. We ensure the mounting surface is suitable and secure; if reinforcement is needed, we install additional bracing.

We also verify that existing gas and water lines can be reused (inspecting for corrosion or scale) or identify what new piping is required to meet code and prevent pressure drops.

We mount your tankless unit securely at the chosen location (typically on an exterior wall or in a utility area). We then connect the gas supply line with proper sizing, pressure testing, and leak detection using soapy water at all joints. We connect the water inlet and outlet lines with appropriate thermal expansion tank (if needed) and pressure relief valve.

We verify all connections are code-compliant and properly secured. If new venting is required, we install concentric or conventional vent piping to the exterior, ensuring proper slope and clearance per manufacturer spec. We also connect any electrical wiring (for ignition and controls) and verify 120V power supply.

Once everything is connected, we bring your system to life in stages. We first verify water flow and temperature stability—checking that hot water reaches all fixtures at consistent temperature. We test both low and high demand conditions (single fixture vs. multiple simultaneous use) and measure actual output. We verify gas ignition, flame quality, and safety shutoffs.

We test the thermostat/control panel to ensure it responds correctly to temperature settings. We calibrate your system’s setpoint and discuss energy-saving recommendations. Before we leave, you receive a comprehensive commissioning report documenting: unit model and serial number, installation specs, performance test results, warranty information, thermostat user guide, maintenance schedule reminders, and contact information. We review the report with you and answer all questions.
