FAQs
What is included in your upfront pricing for tankless water heater installation?
Our upfront price is a single, flat figure that covers every step of the project—no hidden add-ons later. It includes the new tankless water heater unit, all required gas or electrical upgrades, venting materials, isolation valves, any code-mandated earthquake strapping, local Oakdale permit fees, removal and recycling of your old water heater, complete labor, and a final performance/combustion test. The only time the price changes is if you ask for additional work that wasn’t discussed during the initial on-site assessment, and we’ll quote that in writing before we proceed.
How do I know what size or capacity tankless unit my Oakdale home needs?
During your free in-home assessment, we measure peak hot-water demand (showers, appliances, fixtures), incoming water temperature, and gas/electrical service capacity. We then calculate the required flow rate (gallons per minute) and temperature rise, and match those numbers to manufacturer specifications. Most Oakdale homes end up with a 7–10 GPM gas unit, but larger households or homes with luxury fixtures may need 11 GPM or multiple units. We always provide at least two model options and explain the pros and cons of each so you can choose confidently.
How long does a tankless water heater installation take from start to finish?
Once the permit is approved, a standard replacement—swapping a tank for a single wall-mounted tankless unit—takes about 5–7 hours. Projects that require upsizing the gas line, upgrading the electrical circuit, or core-drilling a new vent often run 8–10 hours. If you schedule a morning appointment, you’ll typically have hot water again before dinner. We never leave you without water overnight unless we’ve arranged a multi-day, multi-unit job in advance.
Are there energy savings and rebates available for tankless water heaters in Oakdale?
Yes. A high-efficiency (condensing) tankless unit can cut water-heating energy use by 20–40 % compared to a standard gas tank. PG&E and the State of California periodically offer rebates—currently up to $300 for ENERGY STAR-qualified condensing models. Federal tax credits may add another 10 % of the installed cost (capped at $600). We handle the paperwork, supply serial numbers, and guide you through online rebate submissions so you receive every dollar you’re entitled to.
Do tankless water heaters require regular maintenance?
To keep the heat exchanger clean and maintain warranty coverage, manufacturers recommend a full flush and descaling once a year (more often if Oakdale’s water hardness exceeds 12 grains). We offer an optional maintenance plan that includes annual flushing, filter cleaning, performance check, and software updates for Wi-Fi–enabled units. Regular maintenance extends the life of the unit, maintains efficiency, and helps avoid unexpected error codes.
What warranties and guarantees do you provide?
All tankless models we install carry a 12- to 15-year manufacturer heat-exchanger warranty and 5-year parts warranty. Our workmanship is guaranteed for life; if any connection we install leaks or fails, we repair it at no charge. We also offer a 1-year 100 % satisfaction guarantee—if the system doesn’t perform as promised and we can’t correct it, we’ll remove it and refund your money. Every warranty and guarantee is presented in writing before you authorize the job.
