The ASI Difference

Why San Diego Homeowners Choose ASI for Water Heaters

With over seven decades serving San Diego, ASI has built a reputation for honest plumbing service you can count on. You Can Trust the White Glove Guys.

Same-Day Plumbing Service

Plumbing emergencies can't wait. We offer same-day service with no extra charges for nights or weekends. Call us and a real person will answer—not a machine.

Licensed, Certified Plumbers

Our plumbers are fully licensed, insured, and background-checked. Every technician upholds our White Glove standard of care and professionalism.

Upfront, Honest Pricing

We provide a clear quote before any work begins. No hidden fees, no pressure—just honest recommendations based on what your home actually needs.

Guaranteed Workmanship

We stand behind every job with comprehensive warranties on parts and labor. If something isn't right, we'll make it right.

Advanced Leak Detection

Hidden leaks behind walls or under slab foundations waste water and damage your home long before they surface. Our plumbers use electronic and acoustic equipment to locate the exact source without tearing up floors or drywall, so repairs stay targeted, faster, and less disruptive to your household.

No Overtime Charges, Ever

Plumbing problems rarely happen at a convenient time. ASI charges the same flat rate whether your appointment falls on a weekday morning, a weekend, or a holiday evening. You never pay an after-hours premium, so you can call the moment you notice trouble instead of waiting and risking more damage.

Whole-Home Plumbing Expertise

From the water heater and main line to every fixture and drain, ASI services your entire plumbing system. Because one team knows your home, we spot related issues early, recommend practical fixes, and help San Diego homeowners stay ahead of hard water buildup and aging pipe problems.

I recently had maintenance done on my AC and furnace by ASI, and I wanted to highlight the great experience I had—especially with the technician, Jesus. From start to finish, Jesus was extremely professional, thorough, and clearly very knowledgeable about his work. He took the time to carefully service and clean both the AC and furnace, making sure everything was running properly and efficiently. What really stood out to me was his attention to detail—he didn’t rush the job and even went the extra mile by cleaning the outside of the unit, which I truly appreciated. On top of that, his customer service was outstanding. He was friendly, respectful, and took the time to explain what he was doing, which gave me a lot of confidence in the work being performed. Overall, I’m very satisfied with the service and the level of care provided. I will definitely be using ASI again in the future and would highly recommend requesting Jesus if you want the job done right.

After 21 years of faithful service our heater finally gave out. ASI came to the house and we went over a few options as to repair or replace. We elected the latter, and the very next morning ASI was on site with the new heater. Within 6 hours, Sebastian Garcia and his helper had the new heater installed. Sebastian spent some time explaining how to use the new thermostat, which is so much easier to use than the previous one. By the time they left the garage was clean and all the old stuff was carted away. A great job by an outstanding company. This morning I checked my old paperwork and found that the new heater and thermostat were only a couple of hundred dollars more than the ones I had purchased 21 years ago. ASI really offers good prices and great equipment. A special thanks to the service manager Joe Gondak for keeping in touch with the crew to insure there were no problems during the installation
FAQ

Water Heater Questions Answered

A conventional tank water heater typically lasts 8–12 years; tankless units often last 20+. If yours is older and acting up, we’ll help you decide between repair and replacement.

If the unit is under ~8 years old and the issue is isolated, repair usually makes sense. Older units with leaks, rust, or repeated problems are often better replaced. We give honest, upfront recommendations.

Yes. We size, install, and convert homes to high-efficiency tankless systems — handling the gas, venting, and water-line changes they require.

No. ASI never charges overtime for evenings, weekends, or holidays — the price we quote is the price you pay.
