Manny is truly outstanding! Tim and Tori have consistently provided excellent service for the past 8 years, taking care of three of our homes. We recently had two new installations done, and this time the company exceeded all expectations. Manny and Geo are incredibly knowledgeable, responsive, and thorough. They took the time to sit down with me and explain everything in detail.

From the way beginning, back in April, my wife and I saw 3 different companies to see what is the best fit for us. One was very confident and was trying very hard to sell us. The second person, she was a little more friendly but still didn't fit our request, third person was just all over the place, and finally 1st Choice came along. Tim, who was very knowledgeable, courteous, and friendly, told us everything

Manny came in ready to get my AC back up and working, he began by ensuring the component was in stock and available. When he showed up at the house he worked tirelessly and diligently despite the 106 deg heat. He completed the job perfectly ensuring the unit was cleaned and working properly. He checked the house inspecting the vents to ensure air was coming out at the right temperature.

Common Water Heater Problems We Fix

Water heaters are hardworking appliances that run day in and day out, and over time, wear and tear can cause a range of issues. The most common water heater problems we repair include:

No hot water
A complete loss of hot water can be caused by a failed heating element, broken thermostat, tripped breaker, pilot light issues, or gas supply problems.
Not enough hot water
If hot water runs out faster than it used to, your tank may have sediment buildup, a failing heating element, or an undersized system for your household’s needs.
Lukewarm or inconsistent water temperature
Thermostat issues, sediment in the tank, or a malfunctioning heating element can cause water that never gets fully hot or fluctuates between hot and cold.
Strange noises (popping, rumbling, banging)
Loud noises from your water heater usually mean sediment has hardened on the bottom of the tank and needs to be flushed, or internal components are wearing out.
Leaking water heater
Leaks can come from loose connections, a faulty pressure relief valve, corrosion, or a cracked tank. Even small leaks can cause serious water damage if ignored.
Discolored or rusty water
Brown, yellow, or rust-colored hot water can signal corrosion inside the tank or deteriorating anode rods that need replacement.
Low water pressure from hot water taps
Sediment buildup or a partially blocked supply line can restrict hot water flow to your faucets and showerheads.
Water heater is constantly running If your unit never seems to turn off, it could be working too hard due to thermostat problems, leaks, or heavy sediment buildup reducing efficiency.

If you notice any of these warning signs, it is time to call for professional water heater repair before the problem gets worse.

Signs You Need Water Heater Repair

Sometimes water heater issues are obvious—like a puddle of water on the floor. Other times, the symptoms are more subtle. Watch for these common signs that your water heater needs attention:

Cold or lukewarm showers when you expect hot water
Water that takes much longer to heat up than normal
Unusual sounds like rumbling, hissing, or banging
Visible moisture, rust, or corrosion around the unit
Water is pooling at the base of the tank
A sulfur or rotten egg smell from hot water taps
Sudden spikes in your energy or water bills
Age of the unit (most tank water heaters last 8 to 12 years)

Do not wait until you are completely out of hot water or dealing with a flooded utility room. Early repairs are almost always cheaper and easier than emergency replacements.

Our Water Heater Repair Process

When you call 1st Choice Mechanical for water heater repair, our goal is to get your system back up and running as quickly as possible with a repair that lasts. Here is what to expect:

Thorough inspection and diagnosis
A licensed plumber inspects your water heater, checks gas or electrical connections, tests components, and identifies the root cause of the problem.
Clear explanation and repair options
We explain what is wrong in plain language, walk you through your repair or replacement options, and provide upfront pricing so you can make an informed decision.
Professional repairs
Using quality parts and proven techniques, we handle the repair efficiently and safely, whether it is replacing a heating element, flushing sediment, fixing a valve, or addressing a leak.
System testing

Maintenance recommendations If we spot other issues or your unit is nearing the end of its lifespan, we let you know what to watch for and help you plan for the future.

Tank vs. Tankless Water Heater Repair

1st Choice Mechanical repairs all types of water heaters, and the approach depends on whether you have a traditional tank model or a modern tankless system.

Tank Water Heater Repair

Traditional tank water heaters store and heat 30 to 80 gallons of water at a time. Common repairs include: Replacing heating elements or thermostats

• Flushing sediment buildup
• Fixing or replacing pressure relief valves
• Replacing anode rods to prevent corrosion
• Repairing leaks in supply lines or drain valves

Tank units are generally straightforward to repair, and most issues can be resolved without replacing the entire system—unless the tank itself is corroded or cracked.

Tankless Water Heater Repair

Tankless water heaters heat water on demand and do not store hot water in a tank. They are more complex systems that may need: Descaling and flushing to remove mineral buildup

• Cleaning or replacing burners and heat exchangers
• Diagnosing and resetting error codes
• Repairing ignition or gas flow issues
• Fixing electrical or sensor malfunctions

Tankless systems require specialized knowledge and equipment, so it is important to work with a plumber who understands how these units operate and how to maintain them properly.

When to Repair vs. Replace Your Water Heater

Not every water heater problem requires a full replacement. Our technicians will help you decide whether repair or replacement makes the most sense based on:

Age of the unit
If your water heater is under 8 years old and the repair is minor, fixing it is usually the smarter choice. If it is over 12 years old and showing multiple issues, replacement may save you money in the long run.
Cost of the repair
As a general rule, if the repair costs more than half the price of a new unit and your heater is already older, replacement is often a better investment.
Extent of the damage
A cracked or heavily corroded tank cannot be repaired. Leaks from the tank itself mean it is time for a new water heater.
Energy efficiency Older models are far less efficient than today’s water heaters. Upgrading can lower your energy bills and provide more reliable hot water.

We never push unnecessary replacements. If your water heater can be repaired safely and affordably, that is what we will recommend.

Benefits of Professional Water Heater Repair

Attempting DIY water heater repairs can be dangerous and often makes the problem worse. Professional water heater repair offers:

Safety first
Water heaters involve gas lines, electrical connections, high temperatures, and pressurized systems. Trained plumbers know how to work on these units safely.
Accurate diagnosis
What looks like a simple issue can be caused by multiple underlying problems. A professional pinpoints the real cause and fixes it right the first time.
Warranty protection
Many water heater warranties require professional installation and repair to stay valid. DIY work can void your coverage.
Long-lasting repairs
Quality parts and proper installation mean your repair lasts longer and performs better than a quick patch job.
Peace of mind You can trust that the work was done correctly and your system is operating safely and efficiently.

Preventive Maintenance to Avoid Future Repairs

Regular water heater maintenance can extend the life of your unit and help you avoid costly emergency repairs. 1st Choice Mechanical offers water heater maintenance services that include:

Flushing the tank to remove sediment
Inspecting and replacing anode rods
Testing pressure relief valves
Checking thermostats and heating elements
Inspecting gas lines, burners, or electrical connections
Looking for signs of leaks or corrosion

An annual water heater tune-up is a small investment that can add years to your system and keep your hot water flowing reliably.

Frequently Asked Questions About Drain Cleaning

How much does water heater repair typically cost?

The average water heater repair costs between $200 and $800, depending on the issue. Simple fixes like replacing a thermostat or heating element are on the lower end, while more complex repairs like fixing a gas valve or pressure relief valve cost more. We provide upfront pricing before starting any work so you know exactly what to expect.

How long does a water heater repair take?

Most water heater repairs can be completed in 1 to 2 hours. Simple component replacements like thermostats or heating elements are usually done within an hour, while more involved repairs like flushing sediment buildup or replacing multiple parts may take a bit longer. We work efficiently to get your hot water restored as quickly as possible.

Should I repair or replace my water heater?

If your water heater is under 8 years old and the repair is straightforward, fixing it usually makes sense. However, if your unit is over 10 years old, needs frequent repairs, or has a cracked tank, replacement is often the smarter investment. We will assess your system honestly and help you decide which option saves you the most money in the long run.

Can I repair my water heater myself?

We do not recommend DIY water heater repairs. These systems involve high-pressure water, gas lines, or electrical connections that can be dangerous if handled incorrectly. Professional repairs also protect your warranty, ensure the work is done safely, and prevent you from accidentally causing more damage that leads to costlier repairs.

Do you repair both tank and tankless water heaters?

Yes, we repair all types of water heaters, including traditional tank models and modern tankless systems. Tankless units are more complex and require specialized knowledge and equipment, which our licensed plumbers are fully trained to handle. Whether you have gas or electric, tank or tankless, we have the expertise to diagnose and fix the problem.
