Protect Your Water Heater Investment with Annual Maintenance

Your water heater works hard every day—heating water for showers, dishes, laundry, and more. Over time, sediment builds up inside the tank, the anode rod corrodes, and components wear down. Without regular maintenance, your water heater loses efficiency, costs more to operate, and is far more likely to fail prematurely or develop leaks that can cause costly water damage.

ASI’s professional water heater maintenance service includes a complete inspection, tank flushing, anode rod check, and safety verification. The White Glove Guys service all brands and types—tank and tankless, gas and electric. Regular maintenance can extend your water heater’s life by years and keep your energy bills in check.

Why Maintenance Matters

What Happens When You Skip Water Heater Maintenance

Neglecting annual maintenance leads to these preventable problems.

Sediment Buildup

San Diego's hard water causes minerals to settle at the bottom of your tank, creating an insulating layer that makes the burner work harder and reduces heating efficiency. Annual flushing removes this buildup.

Higher Energy Bills

A water heater with sediment buildup uses significantly more energy to heat the same amount of water. Regular maintenance keeps efficiency high and operating costs low.

Tank Corrosion & Leaks

The anode rod inside your water heater sacrificially corrodes to protect the tank. Once it's depleted, the tank itself begins to rust. An annual anode rod check prevents expensive tank failure.

Premature Failure

A well-maintained water heater can last 12-15 years or more. Without maintenance, many fail in just 6-8 years. Annual service is the most cost-effective way to protect your investment.

Our Process

What's Included in Our Water Heater Maintenance

A comprehensive service designed to keep your water heater safe, efficient, and long-lasting.

1. Safety Inspection

We inspect the pressure relief valve, gas connections or electrical components, venting, and surrounding area for any safety concerns. Your family's safety comes first.

2. Tank Flush or Descale

For tank units, we drain and flush sediment from the bottom of the tank. For tankless units, we run a descaling solution through the heat exchanger to dissolve mineral deposits.

3. Anode Rod Check

We inspect the sacrificial anode rod that protects your tank from internal corrosion. If it's significantly depleted, we'll recommend replacement to extend your tank's lifespan.

4. Performance Verification

We verify proper thermostat settings, check for leaks, ensure proper flame characteristics (gas), and confirm the unit is operating efficiently. You'll receive a summary of our findings and any recommendations.

I recently had my HVAC serviced by ASI and I can’t tell you how happy and relieved I am. Weeks earlier (back in March) I had my system HVAC serviced by Mauzy. After Mauzy left I found the cover not completely seated/installed back on the outdoor condenser unit and a screw laying on the concrete. Additionally, James L., provided me with a list (estimate via email) for the following: 1. Perform condenser coil wash $777.68 2. Remove and replace 40-amp contactor $686.86 3. Install a surge protector (SPD) $994.28 4. Replace HVAC ignitor $362.16 5. Replace flame sensor $362.16 6. Add (to the HVAC system) an extra UV (bulb) system $1,348.74 a. Grand Total = 4,531.88 Back in October 2021 Mauzy billed me $614.06 for 3 to 6 Lbs., of R410A. Back in November 2023 Mauzy billed me $2,345.89 for a new thermostat. Also, during our interaction, he was really pushing for the SPD and indicated the other components will soon fail. He made a statement that some of these SPD’s have an “expiration date” some only good for three years. I told him I have a Surge Protection Device at the main service PNL however he stated this was not good enough. As a certified CA., State WA., State Journeyman electrician I know this was not true and he was comparing an SPD to a carton of milk, very concerning. I then knew I was dealing with a technician with no electrical/HVAC knowledge – he only wanted to sell something. Shortly after he left, I started receiving TEXTS from Kaiya B., (from Mauzy) who was attempting to schedule the recommended service by James L. This is when I notified Kaiya B., that I found a cover loose and a screw on the ground and how disappointed I believed the service was. She got right back and stated she will forward my message to the General Manager however as of this writing I have not heard from anyone at Mauzy. I then contacted ASI and scheduled a full heating and AC service and inspection to ensure nothing else was left incomplete. That’s when the ASI technician discovered two refrigerant caps were missing. These are the caps they remove to measure the R410A refrigerant during operation (discovered by ASI) and are only accessible after removing the condenser cover. These caps were present last year during the service as I observed the service. Additionally, this is a 2025 California Plumbing Code requirement. In closing I I’m really disappointed. As an Army Veteran, 40+ years as an electrician, former building inspector and presently a plans examiner for several jurisdictions in California I feel this is a case of taking advantage of elderly people and over pricing services. The ASI technician could not believe the Mauzy price for coil wash, which was completed by ASI as part of the service call today for $87.00. The additional (other) items on the repair list from Mauzy, ASI stated were not needed looked brand new. I would like to thank the technician Jack Ryan (and ASI) for their honesty/knowledge of the system/thoroughness of the inspection/maintenance and transparency pricing. Additionally, I received a coil wash as part of the system check for a savings of $777.68 dollars. Thanks, Jack, for all your great work, honest pricing and not attempting to take advantage of an Army Veteran 😊. Scott Humphrey San Diego (Crest)

Another great inspection (free) that is included in my membership with ASI. The technician, Travis Tibiatowski was extremely efficient. He answered all my questions and explained things. He inspected every nook and cranny, where water could escape, and found a couple of areas that needed attention. Travis was an extremely nice young man. I would thoroughly recommend Travis and ASI. I wish we had had this service many years ago. Definitely worthwhile.
FAQ

Water Heater Maintenance Questions Answered

We recommend annual maintenance for all water heaters. San Diego’s hard water causes faster sediment buildup than areas with soft water, making regular flushing especially important for extending your water heater’s life and maintaining efficiency.

A standard water heater maintenance visit takes 45-60 minutes for tank units and about the same for tankless descaling. The tank flushing process requires draining the tank, which takes some time, but our technicians handle everything efficiently.

Yes. Tankless water heaters need annual descaling to remove mineral deposits from the heat exchanger, especially in San Diego’s hard water. Without regular descaling, mineral buildup reduces efficiency, triggers error codes, and can damage the unit.

The anode rod is a metal rod inside your tank water heater that attracts corrosive elements in the water, sacrificially corroding so your tank doesn’t. Once the anode rod is fully depleted, your tank begins to rust from the inside. Checking it annually and replacing it when needed can add years to your water heater’s life.
