What Our Customers Say About Us
Traditional Tank Water Heaters
If you're looking for a dependable and budget-friendly option, a traditional tank water heater is a solid choice. These systems store a set amount of hot water and are ideal for families with predictable hot water usage. Our team can help you choose the right size and model for your home.
Tankless Water Heaters
For homeowners who want energy efficiency and on-demand hot water, a tankless water heater is worth considering. These systems heat water only when it’s needed, helping reduce energy bills and saving space in your home. Koala Cooling & Plumbing is a Navien Certified Installer and Service Provider, proudly recognized on Navien’s official website for trusted installation and service.
When You Should Replace Your Water Heater
Most water heaters aren’t shy about letting you know when it’s time for a replacement. If you’re noticing inconsistent hot water, strange noises, or an unexplained spike in your energy bill, your water heater may be nearing the end of its life. These signs usually mean the system is working harder than it should, costing you more and delivering less comfort.
Age is another big indicator. Traditional tank water heaters typically last 8–12 years, while tankless models can go a bit longer with proper maintenance. If yours is getting up there in years, it’s smart to start planning for a replacement before it fails completely. A proactive upgrade can save you from the headache of an emergency repair or unexpected water damage.
Rusty water coming from your hot water tap is never a good sign. It often means corrosion has started inside the tank, and once that begins, leaks aren’t far behind. Popping or rumbling noises from the tank can also point to sediment buildup, which reduces efficiency and puts extra strain on the system.
Leaks, even small ones, should never be ignored. A slow drip can quickly turn into a bigger problem, damaging floors or walls and leading to costly repairs. If you spot moisture around the base of your unit, it’s time to call in a professional to inspect it.
Faq
Standard tank water heater replacement typically runs $2,400 to $3,900 installed. Tankless water heaters run $4,000 to $7,800 installed depending on size and whether gas line or venting upgrades are needed.
Tankless makes sense if you have a gas line, multiple bathrooms, and plan to stay in the home 8+ years — they last 20+ years, deliver endless hot water, and cut energy bills 20–30%. Stick with a traditional tank if you're on a tighter budget, have lower hot water demand, or want a simpler swap. We'll lay out both options with real numbers for your home before you decide.
A standard tank-to-tank swap is usually completed in 3 to 5 hours. Tankless installations or conversions from tank to tankless take 6 to 8 hours, sometimes a full day if gas line upsizing or venting modifications are needed. You'll have hot water back the same day in almost every case.
Standard tank water heaters typically last 8 to 12 years in Central Texas — our hard water shortens that timeline considerably. Tankless units last 20+ years with proper maintenance. If your tank is over 10 years old, leaking, making popping sounds, or producing rusty water, it's time to plan a replacement before it fails on its own schedule (which is always at the worst possible moment).
For tank heaters, the rule of thumb is 40 gallons for a 1–2 person home, 50 gallons for 3–4 people, and 75+ gallons for larger households. For tankless, sizing is based on gallons per minute (GPM) — typically 7–9 GPM for a 2-bath home, 9–11 GPM for 3+ baths.
