Water Heater Replacement in Kansas City
No hot water, or a tank that is leaking or on its last legs? Standard tank replacement is $1,600 flat, parts and labor in, old unit hauled away. Tankless too. Done in house by a licensed Master Plumber.
A Cold Shower Should Not Have to Wait
A water heater is one of those things you never think about until it quits, and it always seems to quit at the worst time. When it does, you do not want a runaround or a mystery bill. You want a straight answer and hot water back fast.
Duct Daddy is a licensed mechanical and plumbing contractor, so a new water heater is handled by the same crew you already trust with your ducts and HVAC. We size the unit to your home, install it to code, haul the old one away, and give you one flat, written price before we start. No hidden fees, no upsell games.
Pick What Fits Your Home
Not sure which way to go? That is what the free in-home quote is for. Here is the honest tradeoff.
Tank Most common
The classic 40 to 50 gallon tank. Lower cost to install and simple to service. A great fit for most KC homes.
- Lowest up-front cost
- Simple, proven, easy to service
- Often a same-day or next-day swap
- Gas or electric
Tankless Upgrade
On-demand hot water that never runs out and mounts on the wall to free up floor space. Costs more up front, saves on energy over time.
- Endless hot water, never run out mid-shower
- Frees up floor space
- Longer lifespan and lower energy use
- Great for busy or larger households
What It Costs
Real starting prices, parts and labor included. We confirm the final number after we see your unit, its age, and the hookups, and you approve it before we touch a thing.
| Service | Price |
|---|---|
| 40 or 50 gallon gas, standard vent | $1,600 |
| 40 or 50 gallon electric | $1,300 |
| 50 gallon power vent | $3,000 |
| 75 gallon gas | $3,200 |
| Hybrid / heat pump, 50 gallon | $3,800 |
| Tankless, like-for-like replacement | $4,500 |
| Tank to tankless conversion | $5,500 quoted after a walk-through — gas line capacity decides it |
| Water heater flush & inspection | $150 $100 added to another visit |
| Tankless descale | $250 |
| Expansion tank | $175 |
| Minor repair (element, thermostat, valve) | from $200 |
Every price includes parts and labor, a new expansion tank where code requires it, and haul-away of the old unit. Financing available on larger jobs. Tankless installs are quoted in person because the setup varies home to home.
Signs It Is Time to Replace
- The unit is more than 10 to 12 years old
- Rusty, cloudy, or metallic-smelling hot water
- Popping, rumbling, or banging from the tank
- Water pooling or dripping around the base
- You run out of hot water faster than you used to
- The pilot keeps going out, or the burner will not stay lit
Water on the floor around the tank? Do not wait on that one. Call us before a slow leak becomes a flooded basement.

One Company, Licensed for the Whole Job
A water heater swap touches gas, water, and venting. We hold a Master Plumber license and do the whole job in house, to code, with a new expansion tank where the code requires it and a pressure-tested gas connection before anything gets lit. You get photos of the work and one flat price you approved up front. No subs, no surprises.
"They showed me exactly what was wrong and explained multiple options. Instead of putting a band aid on my issue they completely replaced and corrected it. They were polite, cleaned everything up, and did a great job. I highly recommend them!"

Frequently Asked
How much does a new water heater cost in Kansas City?
A standard 40 to 50 gallon tank replacement is $1,600 flat, parts and labor included, with the old unit hauled away. Electric is $1,300. Power vent is $3,000, 75 gallon is $3,200, heat pump hybrid $3,800, and tankless starts at $4,500. We confirm the final number after we see your unit and you approve it before we start.
Do you install tankless water heaters?
Yes. We install both traditional tank water heaters and tankless on-demand systems. Tankless costs more up front but does not run out the way a tank does and takes up far less space. We will walk you through which makes sense for your home during the free quote.
How do I know if my water heater needs replacing?
Common signs are age over 10 to 12 years, rusty or discolored hot water, popping or rumbling from the tank, water pooling around the base, or simply running out of hot water faster than it used to. If you see water on the floor, call us right away.
Who does the installation?
Our own crew. Duct Daddy is a licensed mechanical and plumbing contractor, so water heaters are handled in house and to code, never subbed out. We haul the old unit away when we are done.
How fast can you replace a water heater?
Most standard tank replacements are a same-day or next-day job once you approve the quote. A cold shower is not something that should wait, so we move quickly, seven days a week.
