Nothing throws off a morning faster than a shower that turns ice-cold halfway through. KO HVAC is the Kingston, PA team for water heater repair and installation, water softeners, and small plumbing fixes.
Maybe the tank is leaking, the faucet won't stop dripping, or white crust coats every showerhead. From tight basements in older Kingston homes to brand-new utility rooms, we fit the right unit to the space. Whatever's going on, one call gets it handled, with the price in hand before we start.

Here's everything we take care of, from the tank in the basement to the spigot out back.

No hot water, rusty water, or a tank that rumbles and leaks? We find the cause, replace the worn part, from a heating element to a gas valve, and test the hot water before we leave.

New tank water heaters matched to your household, so the last shower of the morning stays hot.

Hot water on demand that won't run out mid-shower, in a wall-mounted unit that frees up basement space.

Softer water that fights white scale on fixtures, helps soap lather, and eases the strain on your water heater.

We fix drips, leaks, and wobbly handles, or install a fresh faucet where the old one gave up.

As plumbing experts, we repair or replace leaky or frozen outdoor spigots, also called hose bibs, so they're ready for Pennsylvania winters.

Water heater repairs typically run about $150 to $700, while a replacement costs more, especially for tankless. Your household's water use and the space the unit goes into shape the final number.
To pin down your number, every repair starts with a $99 diagnostic, then a flat-rate price you approve before work begins. New water heaters and softeners get a written quote from KO HVAC first. Smaller jobs can qualify for 0% financing for 12 months, with approved credit.

Both deliver dependable hot water, and neither is the right pick for every house. The better choice depends on your household, your space, and how long you plan to stay. We'll recommend the one that fits, even when it's the less expensive option.
| Tank water heater | Tankless water heater | |
|---|---|---|
| How it works | Heats and stores a full tank of water | Heats water only when you turn on the tap |
| Hot water supply | Can run low during back-to-back showers | Keeps flowing, up to the unit's flow rate |
| Upfront cost | Lower | Higher |
| Energy use | Keeps water hot around the clock | Heats on demand, so less standby waste |
| Space needed | A spot on the floor | A spot on the wall |
| Typical lifespan | About 10 to 15 years | About 20 years or more |

The same technicians who service your furnace or boiler handle your water heater too. That means fewer strangers through the door and one reliable company for your heating, cooling, and water heater alike.
We focus on water heaters, softeners, and light plumbing, and we say so plainly. If you need a drain or sewer specialist, we'll tell you instead of taking a job we shouldn't. That way, you only pay us for work we do well.
Water heaters often live in cramped basements and closets. We work carefully around your belongings and clean up before we leave. Customers regularly point out how tidy the space looked afterward.
Here's the whole visit, from start to steamy finish.
Step 1
Tell Us What the Water's Doing
Give us a call or book online. No hot water, a slow leak, or rusty-looking water, a quick description helps us arrive prepared.
Step 2
We Find the Cause
A technician checks the unit, its connections, and the water coming out of your tap. You'll hear what's wrong and why, in everyday words.
Step 3
You Choose Repair or Replace
You get a flat-rate price or a written quote, and the decision stays yours. We start only after you approve.
Step 4
Hot Water, Back in Business
We finish the work, test for leaks and temperature, and tidy up. You'll leave knowing how to care for the unit so it lasts.

Calls are picked up day and night, and a person notes what's happening. Between 8 and 5, the office gets you on the schedule. After hours, maintenance plan members can get emergency repairs at an after-hours rate.
Turn off the cold-water valve on top of the tank. Switch off the breaker for an electric unit, or turn a gas unit's control to pilot. Keep kids and pets away from any hot water.
If you smell gas near a gas water heater, leave the house right away. Call 911 or your gas utility from outside, and don't touch any switches.
We work out of Kingston, and the towns below see our trucks all year long. Past them, we serve homes throughout Luzerne, Lackawanna, and Wyoming Counties, within about an hour of our base in Kingston.
Your town never changes the price or the care. Just outside the list? Ask anyway, since our map stretches farther than it looks.

KO HVAC repairs and installs tank and tankless water heaters and water softeners. We also fix and replace faucets and outdoor spigots. Our focus is hot water and light plumbing for homes across the Kingston area.
No. KO HVAC doesn't offer drain cleaning, sewer line work, or major repiping. For those jobs, a full-service plumbing company is the right call, and we're happy to say so.
Age is the first clue, since most tank units last about 10 to 15 years. Rusty water, rumbling sounds, leaks at the base, or hot water that runs out quickly are the others. We'll tell you honestly whether a repair still makes sense.
For many households, yes, especially if you run out of hot water or want the basement space back. Tankless units cost more upfront but heat water only when you need it and often last longer. We'll compare both for your home before you decide.
That noise usually comes from sediment settling at the bottom of the tank, where it traps heat and bubbles. Flushing the tank often quiets it down. If the sound keeps coming back, the tank may be nearing the end of its life.
White crust on faucets, spots on dishes, and soap that barely lathers all point to hard water. A water softener removes the minerals behind those problems. It can also ease the strain that scale puts on your water heater.
Most straightforward tank replacements take a few hours. Switching to tankless or moving the unit's location can take longer. You'll get a timeline with your written quote, so you can plan around it.
