Nothing disrupts your daily routine quite like losing hot water. Whether you have a traditional tank water heater or a modern tankless system, Mark's Heating & Air Conditioning provides expert water heater services to homeowners throughout Sparta, TN, Cookeville, Crossville, McMinnville, and the surrounding Upper Cumberland communities. From minor repairs to complete replacements, our licensed technicians get your hot water back fast.
Common water heater issues include insufficient hot water, water that's too hot or not hot enough, strange noises from the tank, rusty or discolored water, leaking around the base of the unit, and pilot light problems on gas models. Our technicians can diagnose and repair these issues quickly. We also perform routine water heater maintenance, including flushing the tank to remove sediment buildup, testing the pressure relief valve, and inspecting the anode rod — all of which help extend the life of your unit.
If your water heater is nearing the end of its lifespan (typically 8-12 years for tank models), we can help you explore your replacement options. Today's water heaters are more energy-efficient than ever, and we offer both traditional tank and tankless models to fit your household's hot water needs and budget. Tankless water heaters provide endless hot water on demand and take up significantly less space than traditional tank models. Contact us for a free estimate on water heater replacement.
