A properly sized new water heater ends cold showers, rusty water, and surprise leaks in most homes. KO HVAC handles water heater installation and replacement around Kingston, PA, for tank and tankless units. You get a written quote first, and the install happens on a day that suits you.
Whether the old unit sits in a Forty Fort basement or a Dallas utility closet, we fit the new one to the space and to how your household uses water. That means no oversized tank wasting energy, and no undersized one leaving the last shower cold. It's one less thing to think about each morning.

1 shutoff valve
The cold-water valve on top of the tank, which stops a leak in seconds.

Water heaters tend to wear out gradually rather than quit all at once. The signs show up in the shower, in the water itself, and on the floor around the tank. Catch them early, and you can plan a replacement instead of reacting to a flood.
Your shower starts hot, then turns cold before you've rinsed the shampoo out. Sediment can fill the bottom of the tank and crowd out the hot water, or a heating part may be failing. An older unit with this problem is often better replaced than repaired.
Brown or reddish water from the hot tap usually means the tank is corroding from the inside. The rod that protects the tank has likely worn away, leaving the steel exposed. Once rust shows up, a leak is rarely far behind.
Those noises come from hardened sediment, which traps heat at the bottom and makes water bubble through it. Over time, that extra heat stresses the tank and wastes energy. Flushing helps early on, but a loud, older tank is usually on its way out.
A small puddle under the tank is more than a nuisance. It often means the tank itself has started to leak, which no repair can fix. Shut off the cold-water valve on top, and give us a call before it spreads.
Most tank water heaters are built to last about a decade, give or take. After that, efficiency drops and the odds of a leak climb each year. Replacing on your own schedule beats a surprise cold shower on a busy weekday.
On a gas water heater, a pilot or burner that won't stay lit leaves you without hot water again and again. A worn part, poor venting, or a dirty burner can all cause it. On an older unit, repeat outages usually point toward a new water heater.

Installed, a new tank water heater typically runs about $1,200 to $3,000, and a tankless unit about $3,000 to $5,500. The type, size, and fuel set most of the price. Venting, hookups, code updates like an expansion tank, and a switch to tankless shape the rest.
KO HVAC takes a quick look at your space first, so the quote fits your home. You then get a written quote to approve before anything is ordered. New installs can qualify for 0% financing, with approved credit.

Bigger isn't always better, since an oversized tank keeps extra water hot for nobody. The right size depends on how many people shower, do laundry, and run the dishwasher at once. We'll size it to your home and price only what you need.
| 1 to 2 people | 3 to 4 people | 5 or more people | |
|---|---|---|---|
| Typical tank size | 30 to 40 gallons | 40 to 50 gallons | 50 gallons or more |
| If you go tankless | A compact whole-home unit | A mid-size unit | A high-output unit sized to your flow |
| Watch out for | Paying to heat more water than you use | Back-to-back showers draining the tank | Running out during busy mornings |
| Often a good fit | Condos, apartments, and smaller homes | Most family homes | Large households or homes with big tubs |

We ask how many people shower, run laundry, and wash dishes, then size the unit to match. That keeps mornings hot without paying to heat water you'll never use. If tankless fits better, we'll show you why.
Gas lines, venting, and water connections are where installs go wrong, so we take our time on each. We test for leaks and check the water temperature before calling the job done. The space around the unit gets cleaned up too.
There's no juggling a separate plumber and heating company. The same KO HVAC technicians cover both, so your whole system stays in one set of hands. Maintenance plan members also save on repair work down the line.
Each step keeps the hot water off for as short a time as possible.

Step 2
You Pick From a Written Quote
Your quote lays out each option, its price, and the financing in plain terms. Nothing gets ordered until you say yes.
Step 3
Installed and Hooked Up
We drain and disconnect the old unit, set the new one in place, and connect the water, power or gas, and venting.
Step 4

It depends on whether you choose tank or tankless, the size, and the fuel. Venting, hookups, and code updates like an expansion tank can add to the total. KO HVAC puts every water heater replacement quote in writing after a quick look at your space.
Not always. If your household has grown or shrunk, or hot water keeps running out, a different size may fit better. We look at how many people use hot water at once before recommending a size, so you don't pay for more tank than you need.
Yes. Going tankless usually means new venting and, for gas units, a larger gas line, and sometimes an electrical upgrade for electric models. Those changes add to the upfront cost, but the unit frees up floor space and heats water on demand. We'll price both options.
It usually makes sense to stay with the fuel you already have, since switching adds cost. Gas units heat water faster and often cost less to run, while electric units are simpler to install. If you're weighing a switch, we'll price both paths.
Many homes do, especially if the water line has a backflow preventer or check valve. An expansion tank gives heated water room to expand, which protects the tank and your plumbing. We check your setup and include one in the quote if it's needed.
Flush the tank once a year to clear sediment, and keep the temperature at a safe, moderate setting. In hard-water homes, a water softener cuts down on scale. A technician can also check the rod that protects the tank from rust.
