Tankless vs. Traditional Water Heaters

Traditional water heaters store and continuously heat a large tank of water, keeping it ready for use at all times. This design is convenient but less efficient since it wastes energy maintaining water temperature throughout the day. Tankless systems, on the other hand, heat water on demand, providing endless hot water without the need for storage. They take up less space, last longer, and can help lower utility costs over time. For homeowners considering an upgrade, Landry ensures proper installation and maintenance to get the most from your investment.

Maintaining a reliable hot water system is essential for everyday comfort and home efficiency. Landry Mechanical Inc Plumbing HVAC & Electric provides a full range of tankless water heater solutions.

Repair and Troubleshooting

If your unit isn’t producing steady hot water or shows an error code, our team will inspect and repair the problem quickly. We address common issues like clogged filters, ignition failures, and fluctuating temperatures to restore your system’s performance. Each repair is completed with precision to ensure consistent results and dependable operation.

Installation and Replacement

Upgrading to a tankless system can help reduce energy use while providing endless hot water on demand. Our plumbers recommend and install high-quality models suited to your home’s water needs and layout. Every installation is carefully tested for efficiency, safety, and long-term reliability.

Routine Maintenance

Regular service is the best way to protect your system from scale buildup and costly malfunctions. During our Landry tankless water heater service, we flush the heat exchanger, inspect the venting, and verify the system’s flow rate. Preventive maintenance helps extend the lifespan of your water heater and ensures consistent comfort year-round.

Great service, very professional. I called late on a Friday afternoon when my 95 year old dad's boiler failed when temperatures were well below freezing. When I told them he had no heat, they quickly dispatched a technician.
