"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"Andy came over to look at the water heater and told me what he would do and what needed to be done, it was 18 years old and out of code. He was here on time and did a great job and I liked him too. I would recommend Family First and would hire Andy again."

"Absolutely thrilled by the service received by Aurelio and his wonderful company, Northbound Plumbing. The issue for his visit was water gushing onto the countertop from the air gap when running the dishwasher. Aurelio cleared the blockage causing it, something a previous 5-star company was unable to find! Not only have I found the most knowlegable & caring professional, but as future issues arise, as they will, I am so grateful to have finally found the very best! Five stars!"

"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need. When our hot water system suddenly failed, leaving us without hot water for daily essentials, Pedro responded with a level of professionalism, clarity, and compassion that is truly rare. From the very first call, Pedro was attentive, transparent about pricing, and committed to solving the problem quickly. He provided us with the most cost-effective and honest quote out of several we obtained—and, even more importantly, was able to come almost immediately when others could not. His workmanship was precise, efficient, and tidy. It was clear we were in the hands of someone who genuinely takes pride in his craft. In a world where so many service professionals overpromise and underdeliver, Pedro Galvan delivers exactly what he promises—and does so with warmth, integrity, and a deep respect for his clients. We recommend him without hesitation to anyone needing plumbing services."

"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

Water Heaters questions, answered by experts

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

The amount of time it takes to replace an electric water heater will depend on the skill level of the individual who is replacing it. For example, if you replace it yourself–and you don’t have much experience–you can expect the project to take a full day. 

However, if you have a certified plumber or water heater contractor install your new water heater, it can take as little as 2 to 3 hours.

Storage, tankless, heat pumps, and solar water heaters each suit specific space constraints, usage needs, and efficiency preferences.

Basements, specifically those without any air conditioning, are the best location for a hybrid water heater. These rooms are less likely to experience extreme temperature fluctuations, which can affect your hybrid water heater’s efficiency and performance. Basements often have more than enough space for their tanks and proper air circulation. Hybrid water heaters can also be a bit noisy, but putting them in your basement will keep the noise away from your main living areas.

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.
