Water Heater Repair

No hot water in McKinney? Find out what it needs before you replace it.

A water heater that has stopped working does not always need replacing. Sometimes it is a thermostat, an element, a thermocouple or a flame sensor. Sometimes it is sediment. Occasionally the tank really has gone and the honest answer is replacement. The difference between those is a diagnosis, not a sales pitch.

Genzel repairs tank and tankless water heaters across Collin County. Licensed, insured, Texas license RMP-23766.

What we usually find

• No hot water at all. Pilot, thermocouple, heating element or a tripped breaker on electric units.
• Hot water that runs out fast. Often sediment taking up space in the tank, or a broken dip tube.
• Rumbling or popping. Sediment on the bottom of the tank, cooking. Common with hard North Texas water.
• Rusty or smelly hot water. Usually the anode rod, sometimes the tank itself.
• Water in the pan or around the base. Could be a fitting or the T and P valve. Could be the tank. This one gets looked at quickly.

Hard water is why so many fail early here

Collin County water is hard. Minerals settle in the bottom of a tank and insulate the burner from the water, which means longer heating, higher gas use and a shorter life. A flush once a year is the cheapest maintenance in the house.

Repair or replace, answered straight

We will tell you the age of the unit, what is wrong, what the repair costs and what a replacement costs, and then leave the decision with you. If a repair buys you years, we say so. If you are about to spend half the price of a new heater on a twelve year old tank, we say that too.

Good, Better, Best pricing

You get the options and the prices before any work starts, and financing is available if it turns into a replacement you had not planned for.

Guardian Plan members get a free flush every year

The Genzel Guardian Plan includes one water heater flush per membership year, plus 15 percent off every service call and no dispatch fees. It is $27 a month or $282 a year. Flush valves are required for the annual flush, and we can install them if your unit does not have them.

Water heater questions we get asked

How long should a water heater last here?
Less than the brochure says, because our water is hard. Mineral settles in the tank and shortens its life. An annual flush is the single thing that makes the most difference.

My water heater is making a rumbling noise. Is that dangerous?
Not immediately, but it is a warning. The sound is water boiling through a layer of sediment on the tank floor. It means the burner is working harder than it should and the tank is under more stress than it should be.

There is water in the pan under my heater. What now?
Shut off the water supply to the heater and call us. It might be a fitting or the pressure relief valve, which are both repairable. If the tank itself has gone, catching it early is the difference between a replacement and a flooded garage.

Should I repair a heater that is over ten years old?
Sometimes. A cheap part on a well maintained ten year old tank can be worth doing. Spending several hundred dollars on one is usually not, because you are likely to be replacing it soon anyway. We will give you both numbers and let you choose.

Why does my hot water run out so quickly now?
Most often sediment taking up space that used to hold water, or a broken dip tube sending cold water to the top of the tank. Both are diagnosable and neither automatically means replacement.
