"Tap Heating and Cooling came while I was at work and my wife was home taking care of our newborn.  The technician, Jeff, was very polite and very quiet as well (as we had a newborn sleeping) which I found to be amazingly courteous.  He performed the cleaning and inspection of our furnace very quickly and efficiently.  When Jeff was finished, he let my wife know the the circuit board was mounted improperly, but that he went ahead and took care of it as it was a very simple fix.  As well, a filter was included in this service.  I had recently replaced our filter (not realizing I was going to take advantage of this awesome Angie's List deal) and he let my wife know that the filter was still good and that he left a new one next to the furnace for next time.  We recently moved here, but Tap Heating and Cooling is for sure my go-to in the area from now on as they showed nothing but professionalism, honesty, and courteousness while in my home.  Thanks Jeff and Tap Heating and Cooling, I'll see you in summer for my A/C tune up!

"We bought a house recently. The inspection report called for installation of an expansion tank and lengthened drip leg on the HW heater. Jamison Plumbing had installed the new HW tank several months before for the original home owner. Jason called the City of Liberty to determine the exact code requirements. He called back and agreed to the additional work at no charge. He was able to make the changes in a timely manner. His crew called to say they would be later than planned because of an unexpected delay at the preceding job site. We appreciated his willingness to finish the installation according to code and to cover the additional materials and time. It was a great way to be welcomed into a new community.

"The yearly service works out to be $50 a month. We've had two water heaters replaced through them because of a fault in them. They're usually very responsive. I like that I can request the service online. The only thing is, I wish that there was a better avenue for emergency services. If something doesn't work right away usually it takes a couple of days to get someone out and sometimes you can't wait two days without water."

"We were having issues with our hot water heater and had several companies out to diagnose the issue. Evergreen Plumbing has been a blessing. They it only found a fix to keep our old electric water heater going but they gave us the option of installing a new tankless water heater. Jamie really took care of the whole process and gave me confidence in my investment. 10/10 would hire them for all my plumbing needs!!"

Water Heaters FAQs, answered by experts

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.

Often, the first issue you might encounter is a lack or loss of power—this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion.

Unusual noises, lack of hot water supply, efficiency loss, and visible leaks are signs of necessary replacement beyond mere repair.

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.
