There are few things worse than a cold shower on a winter morning. Your water heater is the workhorse of your home, but when it fails, it disrupts your entire routine. We are Kaumakani, HI’s experts in water heater replacement and repair. From standard gas tanks to high-tech tankless water heater installations, we provide the hot water solutions that modern families demand.
Are you tired of running out of hot water? We specialize in converting to tankless water heaters. These units heat water on demand, meaning you never run out, even if the dishwasher and washing machine are running while you shower. We handle the complex gas line upsizing and venting requirements to ensure your new system operates safely and efficiently.
If your tank is leaking from the bottom or simply won't heat, you need a 40 gallon gas water heater installed fast. We offer same-day replacement services. We remove and dispose of your old, leaking unit and install a new, code-compliant heater. We also replace the expansion tank and upgrade the gas valve to ensure safety.
Not every problem needs a new unit. If you have lukewarm water, a pilot light that won't stay lit, or a popping noise (sediment buildup), we can often repair it. We replace heating elements, thermostats, and thermocouples to extend the life of your current water heater.
Whether you need a quick replacement or a high-efficiency upgrade, we ensure your family has reliable hot water. Trust our licensed technicians for a safe install.
