FAQs
What types of water heaters do you install and service in Cosby?
We install, replace, and repair all common water-heater styles, including traditional gas or electric storage-tank units, high-efficiency tankless (on-demand) systems, hybrid heat-pump heaters, and indirect water heaters that integrate with a boiler. Our technicians are factory-trained to work on major brands such as Rheem, AO Smith, Bradford White, Navien, Rinnai, and more, so you get manufacturer-approved service without voiding any warranties.
How do I know whether I should repair or replace my existing water heater?
Age and performance are the two biggest indicators. Conventional storage-tank heaters last about 8–12 years; tankless models can run 15–20 years. If your tank is approaching the upper end of its life span, has visible corrosion, or has started leaking from the bottom, replacement is usually the safest and most cost-effective option. For heaters that are younger but showing issues such as lukewarm water, noisy operation, or pilot-light problems, a repair may restore full service. We offer an honest assessment and provide a written estimate for both options so you can decide with confidence.
What are the benefits of switching to a tankless water heater in Cosby’s climate?
A tankless (on-demand) system heats water only when a tap is opened, eliminating standby heat loss that occurs with a storage tank. Homeowners in Cosby can see energy savings of 20–40 %, endless hot-water supply for large families or vacation rentals, and space savings because the wall-mounted units are compact. Tankless heaters also have a life expectancy of up to 20 years and generally qualify for federal energy-efficiency tax credits and TVA incentives, further offsetting the initial investment.
Do I need a permit to install or replace a water heater in Cosby?
Yes. Cocke County requires a plumbing/mechanical permit for any water-heater replacement or new installation, whether it’s gas or electric. The permit ensures the work meets current plumbing codes, combustion-air requirements, seismic strapping, and pressure-relief valve standards. As a licensed and insured contractor, we handle the permit process, schedule the county inspection, and provide you with the final approval sticker for your records.
How can I extend the life of my new water heater?
Annual maintenance is key. For tank units, we recommend flushing the tank every 12 months to remove sediment that accelerates rust and reduces efficiency—particularly important in Cosby, where moderately hard well-water is common. We also test the temperature-pressure relief (TPR) valve, inspect the anode rod, and verify thermostat calibration. Tankless models need a yearly descaling service to prevent mineral buildup on the heat exchanger. Regular checkups keep your warranty valid, lower utility bills, and add years to the system’s lifespan.
What should I do if my water heater is leaking?
First, turn off the power or fuel supply. For electric heaters, switch off the breaker; for gas units, set the gas knob to “pilot” or shut off the main gas valve. Next, close the cold-water inlet valve on top of the tank to stop additional water from entering. If water is escaping rapidly or you can’t locate the shut-off, call us immediately—our 24/7 emergency service can arrive quickly in Cosby and surrounding communities. Avoid attempting major repairs yourself; leaks can compromise the tank’s structural integrity and pose scalding or electrical hazards.
