Customers say: True professional

"We had a great experience with these folks. Super customer service focused, they let you know who's coming, at what time, with background information on your technician (who was super polite and knowledgeable), which is great for making an intimidating process much easier! I sincerely recommend PMA Mechanical to other families who need heating and air work fast and for a good cost. We'll be going through them for our furnace needs from now on."

"I have used AStar in the past and will continue to use them for all my future heating system needs. AStar staff from telephone reception to the completion of the work by the technician were professional, courteous and knowledgeable.  Technician was prompt and complete all of the work in a timely manner.  Exceptionally thorough in his diagnostic work and in the completion of the repair work required.  He took the time to explain every detail of the job with me and gave me a better understanding of how my heating system works.  I have used AStar in the past and will continue to use them for all of my heating system needs.  Great job and I can't recommend them enough!

Water Heaters questions, answered by experts

If your water heater continues to have issues, you may wonder how long an electric water heat lasts. On average, these units last between 10 to 15 years. Following a proper maintenance schedule can help the water heater live to the end of its average lifespan or longer.

If you have a tank-type electric water heater, it runs regularly to keep the water at the desired temperature. If you live in a home where you don’t use much hot water, it could seem wasteful to run power to heat water that you’re using infrequently. You could save some power by using a smaller tank, insulating the tank, or lowering the temperature of the water heater.

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.

No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing.

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.
