Customers say: Quick response

"Long Holiday Weekend and my hot water heater quit. We had just moved in too. That should have been caught in inspection. Oh well. By chance we had HVAC repair scheduled and they offered to look at the water heater, but My Guy already squeezed us into his schedule. I'm so glad he did. His price came in lower than the HVAC service person's quote. My Guy provided options for repair vs replacement. Knowledge is power, and I feel we were given all the information up front. We opted to replace. He showed us how to operate the water heater and told us the schedule for maintenance to get the longest use of our new water heater. I highly recommend My Guy. We'll have him back again when we replace the sink and dishwasher."

"I had both of my toilets backed up and reached out on Angis and Straight Shooter was the first to respond to my inquiry. They were able to send a technician out the same day and were able to fix my back up issue. I didn't realize my toilets were like 30 years old so they quoted me for replacements and when we decide to do that work we will call them again."

Water Heaters FAQs, answered by experts

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.

There are pros and cons to tankless water heaters. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact. On the other hand, they cost about twice as much to install as traditional tank water heaters and are more limited in terms of flow rate.

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.

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.

Examples include gas stoves, ovens, and water heaters. Confirm with your provider for specific items.
