Largo Water Heater is the local team neighbors call for gas, electric, tankless, and heat pump water heaters: repairs, replacements, maintenance, and upgrades, done quickly and done right.
A dead water heater doesn't wait, and neither should your service company. With technicians based close by, we provide fast, reliable service and hands-on care from experienced pros who know the local water, the local codes, and the way these heaters actually fail.
Sometimes the fix is a new heater. Whether it's a first-time install, an upgrade, or a tank that finally gave out, we size it, set it, and bring it up to code.
Installing a water heater is part plumbing, part gas or electrical work, and part code compliance. Our technicians handle all three, so the heater runs safely and efficiently from day one. You'll know the full installed price before we start.
Tank water heaters typically last 8 to 12 years. When the tank itself starts leaking or the hot water turns rusty, no repair will save it, and the right move is a new heater sized to your household. Every install includes the code details that matter, like an expansion tank where required, a properly piped relief valve, and correct venting, and you'll know the price before we start.
For most Largo homeowners, a water heater repair usually comes in somewhere between $150 and $600. Where you fall in that range depends mostly on which part failed and whether the heater runs on gas or electricity. Every repair starts with a diagnosis and a clear, upfront price.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Heating element or thermostat (electric)Most common electric repair, usually same visit | $150–$350 | No hot water, or a short and lukewarm supply |
| Thermocouple or flame sensor (gas)Burner shuts off seconds after lighting | $150–$300 | Pilot lights but will not stay lit |
| Gas control valveLargest common repair; compare to replacement past 10 years | $300–$700 | Valve will not open or regulate; weigh it against replacement on older tanks |
| Anode rod replacementRotten-egg odor or a rod worn down to bare wire | $150–$350 | Rotten-egg odor or a rod worn down to bare wire |
| T&P relief valveDripping or discharging valve; water pressure checked too | $150–$300 | Worn valve replaced with the correct rating |
| Dip tube replacementHot water runs out fast, plastic bits in aerators | $150–$300 | Hot water runs out fast, plastic bits in aerators |
| Drain valve replacementDrip at the bottom valve, often plastic on older tanks | $100–$250 | Leaking or stuck valve at the base of the tank |
These are common price ranges, not quotes. We confirm the exact price after diagnosing your water heater.
On older tanks we always compare the repair against a replacement, so you can make the call with real numbers. These are typical ranges, not quotes. Call (727) 658-5497 for your price.

If something seems off with your hot water, it usually comes down to one of these. Here are the problems we get called about most, and how we put a stop to each.
When the heater is on but the water stays cold, the fault is almost always one specific component. We find it and fix it fast.
Same-day repair detailsSome leaks are a simple fix at a fitting or drain valve. Others come from the tank itself, which can't be repaired. We tell you honestly which kind you're looking at.
Leak repairA rotten-egg smell in the hot water usually comes from bacteria reacting with the anode rod. Swapping to a different anode and flushing the tank typically fixes it.
Water heater maintenanceA tank past 10 to 12 years that needs a new part every few months is telling you something. We'll give you the honest math on repair versus replacement.
Replacement optionsAn error code on a tankless unit is the heater telling you what it doesn't like, often scale buildup, an ignition fault, or a flow sensor problem.
Tankless repairA growing family, a new soaking tub, or back-to-back showers can outrun a 40-gallon tank. A tankless unit heats water on demand, so it doesn't run out.
Go tanklessExperience is what separates a lasting fix from a temporary one. Our technicians know how these heaters fail (combustion, controls, sediment, corrosion) and match the repair to the actual cause.
Most repair calls are diagnosed and fixed in a single visit because we stock the common parts (thermocouples, elements, thermostats, and relief valves) on every truck.
If a $30 thermocouple fixes it, that's what we'll tell you. We quote repair and replacement honestly, with real numbers, and let you choose, no scare tactics, no pressure.
We don't just swap the failed part. We check what killed it (high water pressure, sediment, a bad vent draft, a loose wire) and correct that too, so the same failure doesn't come back.
Hot water isn't a side market for us, it's the core of what we do. We've learned how local water quality and local construction wear on these systems, so the service you get is tuned to this area rather than copied from a national playbook.
Knowing the area is half the job. We've learned which neighborhoods have hard water, which older homes need their venting brought up to code, and what inspectors here look for on permits, and we put that knowledge to work so each job is done right the first time.

Call (727) 658-5497 and we'll get you a price quote, often within a day. A few quick questions (gas or electric, tank or tankless, what it's doing, how old it is) and we'll book a time that works for you.
We don't guess. The diagnostic covers the full system, including the supply lines and venting, and turns into a plain recommendation with the cost spelled out up front.
Most repairs finish the same visit, since our trucks carry the common parts. Replacements are installed to code with proper venting, sealed connections, and clean workmanship.
We check the water temperature at the tap, test the relief valve, confirm there are no leaks, and walk you through what was done. Optional maintenance visits keep the tank flushed, the anode checked, and the heater running efficiently for years.

There's no mystery to how we handle an urgent failure. Here's the step-by-step of what we do after a homeowner calls for fast help.
The first call is where it all starts. Someone on our team picks up, works out how urgent the situation is, and schedules the soonest visit available, while telling you the few simple things to do in the meantime, like closing the water valve above the tank.
Your technician shows up ready to work, not just to look. The common failure parts ride on every truck, so the visit moves straight from diagnosis into repair.
This is where the problem actually gets solved. We repair what's repairable immediately, and when replacement is the honest answer, we handle draining, removal, disposal, and a code-compliant install without drama.
We don't disappear once the visit is done. We follow up to confirm everything is holding, and for heaters in their later years we'll suggest the maintenance rhythm that keeps them reliable instead of surprising you.
"Our water heater sounded like popcorn every time it kicked on. The tech flushed out a shocking amount of sediment, checked the anode rod, and tested the relief valve. It's quiet now and the hot water seems to last longer too."
"The relief valve pipe kept dripping and I didn't know if it was a big deal. The tech checked our water pressure and found it was way too high, then added an expansion tank and a pressure reducing valve. The dripping stopped completely, and he showed me how to test the valve once a year."
"We went tankless after years of running out of hot water with three teenagers in the house. They sized it for our real usage instead of guessing, upsized the gas line, and ran new venting. The hot water simply never runs out now."
Choosing who works on your water heater is a real decision. Here's what sets us apart from other local service companies.
A maintained water heater simply lasts longer, and we'd rather earn your trust than sell you a tank early. Every maintenance visit is thorough and documented. For older tanks, a new anode rod at the right time can add years to the tank. That's how we work.
Hands-on experience is the gold standard for water heater work. Every technician on our team has real field experience across gas, electric, tankless, and heat pump units, which means your heater is serviced according to proven best practices.
Water heater sizing is simple math, and we show ours. Our team works out the right capacity for your home and installs it to local code, permits included where required.
