Common Water Heater Problems in Hillsborough Homes

Understanding typical water heater issues helps you recognize when professional repair is necessary. Our technicians regularly diagnose and resolve these frequent challenges faced by Hillsborough residents:

  • No Hot Water
    Possibly the most obvious problem, a lack of hot water often indicates heating element failure, thermostat issues, or ignition system faults.
  • Leaking Water Heater Tank
    Leaks can cause water damage and suggest corrosion, cracks, or loose plumbing connections that require immediate service.
  • Pilot or Ignition Failures
    For gas models, pilot lights may go out or ignition systems can fail due to sediment buildup or faulty components.
  • Strange Noises
    Rumbling, popping, or banging sounds inside the tank often result from sediment accumulation heating unevenly.
  • Inconsistent Water Temperature
    Fluctuations in temperature point to thermostat malfunctions or mineral deposits impacting heating efficiency.

Diagnostic Procedures: How Plum HVAC Approaches Water Heater Repair

At Plum HVAC, we believe thorough diagnostics are critical for effective repair. Our Hillsborough technicians follow a comprehensive inspection process that includes:

  1. Visual Tank Inspection
    Checking for external leaks, rust, and signs of deterioration.
  2. Thermostat and Element Testing
    Using specialized tools to assess electrical components for consistent function.
  3. Pilot Light and Ignition Review
    For gas water heaters, evaluating pilot flame stability and ignition controls to ensure reliable startup.
  4. Pressure Relief Valve Check
    Verifying valve function to prevent overpressure hazards and water discharge problems.
  5. Sediment Layer Assessment
    Draining the tank partially to inspect internal sediment buildup, which can erode efficiency and lifespan.

This methodical process allows us to pinpoint the root cause quickly, saving you both time and unnecessary expenses.

Typical Water Heater Repair Solutions We Provide

Once diagnosis is complete, Plum HVAC in Hillsborough offers tailored repair options that extend your water heater’s service life and restore peak performance:

  • Heating Element Replacement
    For electric water heaters, faulty elements are swapped out to reinstate efficient heating.
  • Thermostat Repair or Replacement
    Fixing or upgrading thermostats ensures consistent water temperature control.
  • Leak Repairs and Tank Sealing
    Small leaks can often be sealed. Larger or more severe corrosion issues may require component replacements.
  • Pressure Relief Valve Service
    Repairing or replacing valves helps avoid pressure buildup and potential tank ruptures.
  • Ignition System Fixes for Gas Heaters
    Addressing ignition failure, cleaning pilot assemblies, or replacing thermocouples restores safe operation.

Repair Versus Replacement: What Hillsborough Homeowners Should Know

Deciding between repairing or replacing a water heater depends on several factors specific to your home and appliance condition:

  • Age of the Water Heater
    Water heaters generally last 8-12 years. Older units with multiple failures may cost more over time in repairs.
  • Extent of Damage
    Minor leaks, element failures, or thermostat issues typically justify repair. Significant tank corrosion or repeated malfunctions often call for replacement.
  • Energy Efficiency Considerations
    Newer models offer substantial energy savings, which can reduce utility bills and environmental impact—important factors given California’s ongoing energy concerns.
  • Cost Efficiency
    Our Hillsborough experts provide transparent estimates for repair and replacement, helping you make an informed decision balancing upfront cost and long-term value.

We found Plum HVAC in 2024 after spending more than 2 months searching and comparing estimates.  The owner Sam gave us a very competitive price for a Mitsubishi mini-split and the installation went off without a hitch.  Our experience was so positive that we later requested their services twice more to also install A/Cs for our 2 other rooms.  Their technician, Jake, led our installations each time and we were very impressed by their professionalism and quality of work. Now 1 year in and we could not be any happier, nor have we encountered any issues with our models.

Sam of Plum HVAC, responded to our Heat Pump installation request promptly and provided a very competitive estimate after an onsite visit. He was very flexible and patient to answer and explain our questions. After we signed the contract, he and his team of 4 worked very hard to deliver and install the whole Heat Pump system on time with good quality. I am particularly impressed by their problem solving skills to overcome different connection challenges for the attic installation. Each day before they started, they covered the floors with protection blankets and cleaned after they were done for the day. They also revised the drainage and electric work per the city inspection guidance. Sam and his team were professional and honest so we highly recommend Plum HVAC to any customers who need HVAC work done for their houses.

We needed to install a mini-split in a backyard unit. Sam and his team helped with this, and they did a fantastic job. Sam visited our place and clearly explained to me what needed to be done, and offered a great price. He scheduled the job for a few days later, and his team performed the job with extraordinary quality. Later, I noticed a minor issue and reached out to them. Sam helped me to fix the issue on a second visit by his team later in the week, providing top-notch customer service. I will work with them in the future for my HVAC jobs, and highly recommend them given their excellent work quality and customer service.

I reached out to 4 companies for mini split quotes; Plum HVAC pricing came in the lowest. Beyond that, Sam was very knowledgeable and kind during the in home consultation. He offered a quote in person, & stuck by it. They removed our old furnace, and installed a two head mini split in our two story townhouse. The work as you can see is very clean! The guys who installed it were very fun & professional. Sam & his team were communicative the whole way through including the permitting process. They took roughly one full day for install, which was very fast! Including removal & disposal of our old furnace. Natalie was very helpful throughout the Bayren Rebate process & always available for any questions! This system has changed our lives, wish we would have gotten it done sooner! It’s way better than we could have imagined.

I recently engaged Plum HVAC to install two mini-split units at my residence, and I'm thrilled with the outcome.Throughout the entire process, from the initial consultation to the project's completion, Plum HVAC showcased professionalism and expertise. The technician, Sam, arrived promptly and conducted a comprehensive assessment of my HVAC system. Sam took the time to thoroughly explain the technicians' tasks, the estimated duration of the project, and provided transparent pricing options.

Wonderful experience with Plum HVAC on a heat pump installation! I checked several companies, compared their recommendations, timelines, reputations and prices.Sam, the owner, was very professional and has almost 2 decades of experience in HVAC. When I asked dumb questions, he answered most graciously. And when I noted that some companies we queried said we could get away WITHOUT replacing our original ductwork from 1965, he gave us his honest opinion why that wasn't a good idea. (Hubby remembered later that people who worked in our attic adding insulation told us there were lots of duct leaks.)

Marlene S.

I called 8 different HVAC companies for quotes for a heat pump heating/ac system because I want to save money by switching from a forced air gas furnace to an electric heat pump system which will give me both heating and air conditioning. In addition my old furnace (circa 1991) was way oversized for my home and the air coming out too noisy. The New heat pump system is quieter and more efficient.  Back to the quotes for the system, all the other 7 companies sent a salesperson/advisor to give the quote. Sam, the owner of Plum HVAC came our to give the quote. He was quick with his quote and was very knowledgeable. He didn't try to upsell me on anything and have the lowest quote of them all. His price was 60% less than the highest quote and 15% lower than the next second lowest quote.

Plum HVAC is an extremely professional, knowledgeable, and an established company to hire. I highly recommend Plum HVAC! Sam and his crew did a wonderful job. Sam worked with my schedule and his crew had completed the job with ease.

Sam was one of the most professional business owners I had the chance to meet over the past few years and I'm so happy I trusted him to install our new A/C unit.- He showed up on time- He was transparent (and reasonable) regarding pricing- He offered 2-3 options- His crew did a very clean/thorough jobWhat I loved the most though, was the fact he was very easy to communicate with. I would definitely use him again and recommend him to our neighbors/friends.

We recently had a complicated Bryant Evolution dual fuel system with variable speed and zoning installed in our home by Plum HVAC, and we are very pleased! The team also changed the entire crawl space ducting, ensuring a comprehensive upgrade. The price was fair, and the team was always on time and easy to contact. Sam Mousavi, the head of the team, paid great attention to detail and demonstrated a strong understanding of systems. His expertise in HVAC systems and his friendly character made us feel comfortable throughout the process. We highly recommend Plum HVAC for their professionalism and excellent service.

I cannot say enough about Plum HVAC, who replaced my aging heater furnace, and in particular Sam. Sam was very highly recommended by my sister, who replaced her furnace and added air conditioning.First, they gave me a good deal for a 2-stage, at the same cost as the lowest bid for a 1-stage. The other bids were dancing around some gas line work made by previous owners.
