Gas Water Heater Repair and Replacement

We Keep the Hot Water Flowing

Gas Hot Water Heater

Your gas water heater plays a critical role in providing hot water for daily tasks like showering, washing dishes, and doing laundry. When it malfunctions or reaches the end of its lifespan, it can disrupt your routine. Whether you need repairs to get it back in working order or a full replacement, Horn is here to help with reliable, professional service.

How Your Gas Water Heater Works

A gas water heater uses a burner located at the bottom of the tank to heat water. Cold water enters the tank, where it is heated by the gas burner. The heat is regulated by a thermostat, ensuring the water stays at your desired temperature. Over time, sediment build-up, wear, or component failure can affect its efficiency and performance, requiring maintenance or replacement.

Enjoy the Benefits of a New Water Heater

Gas Water Heater Replacement

Upgrading to a new gas water heater provides numerous benefits, including improved efficiency, as modern models heat water faster while using less energy. You’ll enjoy a consistent hot water supply, eliminating the frustration of running out when you need it most. Reduced energy consumption also leads to lower utility bills, offering significant savings over time. New water heaters often come with advanced features, such as tankless options and enhanced safety controls, for greater convenience and peace of mind.

Signs You Need to Replace Your Gas Water Heater

If your gas water heater is showing signs of trouble, it may be time for a replacement. Common indicators include the age of the unit, as most gas water heaters last only 8–12 years before becoming prone to failure. Rusty water is another warning sign, suggesting internal corrosion that could lead to leaks. Inadequate heating, such as water that isn’t as hot or runs out quickly, often points to a failing system. Visible leaks around the tank are a clear indication of serious damage, while unusual noises like popping or rumbling may mean excessive sediment build-up is affecting performance.
