General Installation Introduce
For California residents and business owners, especially those in the Greater Los Angeles and South Bay areas, ensuring a reliable supply of hot water is more than a convenience—it's an essential requirement. When a water heater fails, whether in a busy commercial property or a family home, immediate and expert service is critical. General Installation, based in Gardena, CA, has been the region's dedicated specialist in water heater sales, service, and installation since 1950, spanning four generations of family ownership.
General Installation distinguishes itself by operating as a focused, all-in-one shop for water heating solutions. While they are a plumber by trade, their expertise is heavily concentrated on the sale, installation, and repair of water heaters for both residential and commercial clients. This specialization allows them to maintain deep knowledge of various systems, from traditional tank units to high-efficiency models, and to stock a comprehensive inventory of replacement parts for immediate service delivery. They proudly serve the L.A. area, offering wholesale pricing on units from industry-leading brands such as Rheem, Bradford White, American Standard, and AO Smith.
The company is particularly notable for its role as an authorized factory service center for several major water heater brands. This certification means that for many homeowners, General Installation is the go-to provider for repairs covered under a manufacturer’s warranty. This status requires a high level of technical proficiency and allows their technicians, who are described as skilled and knowledgeable, to handle complex, warranty-specific service work. For example, technicians like Noe have been highlighted by customers for their exceptional professionalism, expertise, and willingness to thoroughly explain every step of the repair process.
However, as with any high-volume service provider dealing with manufactured products and complex warranty guidelines, customer experiences can vary. While many clients praise the technicians' competence and the quick, efficient service, particularly in emergency situations, one customer's review highlights a challenge associated with warranty labor coverage. This individual experienced multiple failures of a gas valve replacement, noting that while the part was covered under the manufacturer's warranty, General Installation’s labor warranty was only 30 days. They were charged for a diagnostic and labor on a subsequent visit that occurred just outside this internal labor warranty period, leading to frustration regarding the quality of the initial repair and the company's policy on recurring issues. This demonstrates the critical importance of understanding both the manufacturer’s parts warranty and the service provider’s labor warranty when dealing with complex appliance repairs.
Despite this isolated concern, the company’s dedication to customer satisfaction is evident in its long history and its commitment to ensuring all work is done correctly and up to code. They are an A+ accredited business with the Better Business Bureau and offer a 100 percent satisfaction guarantee on every job, aiming to be the only plumbing professional customers in the region will ever need to call for water heater issues.
Furthermore, General Installation understands the urgency of a lack of hot water, offering 24-hour, 7-day-a-week emergency repair services in the Greater Los Angeles area.

General Installation Reviews

★ 5★ 4★ 3★ 2★ 1Noe is exceptional and I can't recommend him highly enough! From the moment he arrived, his professionalism and expertise were immediately apparent. He arrived prepared with all the necessary equipment and took the time to thoroughly explain every step of the process. I could tell he knew exactly what he was doing. Not only that, but he was incredibly patient in answering all my questions. His attitude was amazing—so positive and approachable. Not only did he resolve all of my problems, but he also followed up afterward to ensure everything was still running smoothly.
May 01 · Cindy LiangWe received their contact as an authorized Rheem service provider for our water heater and we called them to have the faulty gas valve replaced.We called mid August 2023 and they came to replace the gas valve. After about 50 days, mid October, the water heater signaled again a faulty gas valve and we called them to get it checked. They came back and charged us again for the diagnostic and 199$ to change the faulty gas valve. The part was under warranty but their job wasn’t, since it was over their 30 days threshold.Mid November, after 39 days from their last visit, the water heater indicated again, for the 3rd time, a faulty gas valve. When I called them I was told they would have charged for the 3rd time the full tariff to come check the water heater since it was after 30 days.They claimed “it’s not their problem” since they “didn’t make the water heater” so I wander why Rheem recommends them as an authorized service provider and if they checked the water heather at all when they came here before.Avoid this company. They do not stand behind their (poor) work and try to keep charging customers extra fees.
November 21 · Paolo CancianiThey came out to replace the gas valve control on our water heater as per recommendation from the manufacturer, Rheem. A few weeks later, it went out again. I called again, and they again got on the phone with Rheem. They recommended again replacing the gas valve control and also a tank sensor. When the parts arrived, they came out again to replace the parts. We have been good ever since. The 2nd visit was N/C since it was under the 30 day labor warranty. Quick, no nonsense service
August 28 · Robert OishiMy wife & I were very pleasantly surprised by their Nordstrom type service on a repair. Tyler took the time to inform us that the repair may be covered under recall so there's no charge to our family. We got a text w the technician's photo so we knew who was coming w the ETA. First class gents - a rare rose amongst many thorns. We're looking forward to bringing them back!
January 21 · Eric YonemuraTook off work 3 times total for this company to send someone one time to work. Contracted through property management company.1st day: No call, no show. Called office, and was apologized to. Person on phone said it was their fault and they would send someone the next day.2nd day: Technician showed up to test water heater. Asked me (tenant) to sign paperwork stating I would pay the service fee before starting work. I stated it was my property management company's responsibility to cover the costs. He hesitated, I called my plumber, who set up the appointment, to confirm with General Installation's tech that work could begin. My understanding was that was confirmed, but I was asked to sign for liability again after the call. I declined.Their technician called his company, and then told me that he couldn't start work without me signing for a service fee.I called my plumber again and he said he would be on his way. I relayed this to General Installation's technician, but he got in his car and drove away, saying he would be "somewhere else."Incredibly unprofessional to leave within 10 minutes of a call that was supposed to happen the day before.3rd day: After my plumber spoke with them again, they finally sent someone out who tested my water heater. He was courteous and professional.A very unpleasant and unprofessional company to deal with. I missed three days of work to do what should have taken one day. I would not use them again, and I don't recommend anyone else does either.
