"My daughter had a great experience with American Mechanical when they installed a Tankless Water Heater. So I called when I needed help figuring out a leak under my kitchen sink. Ed was the plumbing expert that figured out the problem. He provided me with an estimate and answered all my questions. I will use this company to fix this problem and any future plumbing projects I have. Great customer service"

"Having never used gas heat before and just purchasing an older home I wanted to make sure it was in good operating condition and to learn a bit more about how the system worked. Technician took his time to help me understand the system. Provided what I feel was honest information and was very helpful without pushing replacement of what we all knew is a very old system. He made me feel confident the system was in good working condition and performed a very detailed inspection even with an annoying customer standing over him the entire time. Great job

"After calling to explain the problem, was told to turn the system off with the possibility that someone might come out the same day. They called back shortly to set up an appointment for service at an agreeable time the next day (within 24 hours). The two men arrived on time and checked the equipment. They found the likely cause of the problem, were very pleasant, informative, and professional. We plan to set up a seasonal maintenance program with this same company for two independent heating/cooling units in our home.

"Installer came unprepared to to fix fire caulk he damaged as well as not having a lift device to get the water heater onto it's stand. Had to go buy fire caulk at my expense and find a board for him to slide new water heater up to get it on the heater stand."

Water Heaters questions, answered by experts

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

Electric water heaters typically last 10 to 20 years, though proper maintenance can extend their lifespan. If your unit is over a decade old and showing signs of inefficiency—such as higher energy bills, frequent repairs, or leaks—replacement is a smart investment. Tankless models last over 20 years, which can make them a longer-lasting alternative to traditional tank water heaters.

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

One of the primary benefits of a heat pump water heater is how cost-effective it is. How much you save will depend on your water usage and electricity costs. That being said, we can ballpark savings for the average home of between $100 and $500 per year. You can increase that savings rate by researching and applying available energy incentives available in your area. If you really want to focus on cost, consider a tankless water heater.

If you are having trouble determining the right breaker size for your water heater, it is a great idea to contact an electrician near you to help. They can help you determine the best option for your home and install the circuit breaker for you, ensuring that you have all the proper permits and that your circuit breaker won’t overload, which could lead to fire and other damage.
