Signs It's Time for a New Water Heater
Your Current Water Heater Is More Than 10 Years Old
With San Jose's naturally hard water, tank water heaters typically last 8-12 years before mineral buildup and corrosion take their toll. Running an aging unit isn't just inconvenient - it's inefficient, can be unsafe, and unpredictable. You are often a morning away from leaving your entire household without hot water.
Strange Noises From The Tank
Rumbling, popping, or banging sounds usually mean sediment has accumulated at the bottom of your tank. San Jose's moderately hard water accelerates this buildup. As sediment hardens, your water heater works harder, drives up your energy bills, and moves closer to failure.
Consistent Issues
That third call to fix your water heater isn't bad luck, it's a sign. When repair costs start adding up and parts become harder to find, you're essentially funding a failing system instead of investing in a reliable replacement. Most San Jose homeowners find that replacement saves them money within the first year.
Your Energy Bills Keep Climbing
An inefficient water heater can account for up to 20% of your home's energy costs. If you're in an older Cambrian Park or Rose Garden home with the original water heater, you're likely spending hundreds more per year than necessary. Modern high-efficiency models, especially tankless systems, pay for themselves through lower PG&E bills.
The longer you wait with an aging water heater, the more you risk a potential failure that floods your garage or utility room. Proactive replacement beats an emergency installation every time.

Thorough In-Home Assessment
Our licensed & insured plumbers evaluate your current setup, discuss your household's hot water needs, and help you choose between tank and tankless options. We measure your space, check your existing gas lines and venting, and provide transparent pricing before any work begins. For homes in 95125, 95126, and throughout San Jose, we understand the local building codes and permitting requirements needed for the area.
Professional Removal & Disposal
Before we start any repair, we explain what needs to be done, what it will cost, and the multiple pricing options we create for you. We never hand out hidden fees or use pressure tactics. You approve the work, or you don't pay for a repair you didn't fully approve.
Expert Installation
We repair all major brands, including A.O. Smith and Rinnai. Our technicians carry common replacement parts on their trucks, which means most repairs are completed in a single visit.
Code Compliance & Permitting
We handle all permitting and ensure your installation passes inspection. San Jose building codes have specific requirements for water heater installations, including seismic bracing, proper venting clearances, and safety shutoffs. Our team stays up to date on every code update so you never have to worry about compliance issues.
System Testing & Walkthrough
Before we leave, we'll test your new water heater thoroughly, check for leaks, verify proper temperature settings, and walk you through basic maintenance. You'll know exactly how to adjust the temperature, where your shutoff valve is located, and when to schedule your first maintenance flush.
Warranty Registration
We register your water heater warranty and provide you with all documentation. Most tank models come with 6-12 year warranties, while quality tankless systems often include 12-15 year warranties on the heat exchanger.

FAQ
How long does a water heater replacement take?
Most standard tank water heater replacements take 3-5 hours from start to finish. This includes removing your old unit, installing the new water heater, ensuring code compliance, and testing the system. Tankless water heater installations typically take 6-8 hours since they often require gas line upgrades, new venting, and electrical work. We'll give you an accurate timeline during your free assessment. Our team works efficiently and cleans up completely before we leave.
Should I choose a tank or tankless water heater?
It depends on your household's needs and budget. Tank water heaters cost less upfront ($1,500-$3,000 installed) and work well for most families, but they store 40-50 gallons of hot water whether you're using it or not. Tankless systems cost more initially ($3,000-$6,000 installed) but provide endless hot water on demand, last 15-20 years instead of 8-12, and can cut your water heating costs by about 20-30%. For San Jose's hard water, tankless units also resist mineral buildup better than tanks, which is important to know for local San Jose homeowners, especially with older homes. We'll help you weigh the pros and cons based on your home size, hot water usage patterns, and long-term goals.
Do you offer financing for water heater replacements?
Yes, we offer financing options to make water heater replacement more affordable. This is especially helpful when upgrading to a high-efficiency tankless system or if your water heater failed unexpectedly. Contact our office at (408) 898-2500 to discuss available financing terms and find a payment plan that fits your budget.
How does San Jose's hard water affect my new water heater?
San Jose's moderately hard water (7-10 grains per gallon) accelerates sediment buildup inside tank water heaters and can reduce their lifespan if not maintained properly. We recommend annual flushing to remove mineral deposits and extend your water heater's life. For tankless systems, descaling every 1-2 years prevents hard water scale from damaging the heat exchanger. Many homeowners also install water softeners, which protect not just your water heater but all your plumbing fixtures and appliances.
What water heater brands do you recommend?
We install and recommend brands known for reliability and strong warranties: Rheem, Bradford White, and A.O. Smith for tank water heaters, and Rinnai, Navien, and Noritz for tankless systems. We'll discuss specific model recommendations based on your household size, budget, and whether you prioritize energy efficiency, warranty length, or upfront cost savings.
Do you handle permits and inspections?
Absolutely. We pull all necessary permits with the City of San Jose and ensure your installation meets current building codes. This includes proper earthquake strapping, venting requirements, thermal expansion tanks, and safety shut-off devices. After installation, we schedule the required inspection and make sure everything passes. You don't have to deal with any of the paperwork or wait times.
