"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet.  I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."

Water Heaters questions, answered by experts

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.

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.

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.
