We had our water heater go out last week.  We noticed it when we woke up to take showers before work.  I called a few places and ultimately chose to go with Harker because the receptionist told me they would be able to come out and assess the heater and replace it the same day.  Our water heater is about 7 years old, so we figured there would be a good chance that it would cost the same amount the replace the water heater as to just fix the older one, so that is why I verified with her that they could fix it the same day.

 

We have a new rescue dog that is not good around men, so my SO came home from work (I had already taken the day off work for this) and she took the dog away from the house so we didn?t disturb the men while they worked.  As we expected, there were a few parts that were bad on the water heater and the cost would be similar to repair or to replace.  He was done looking at the water around 2:00 and he told me someone would call me for a quote.  I was confused as I was under the impression that they would replace it that same day per the lady on the phone.  Apparently, that was not the case.  This guy wasn?t even the guy who would replace the unit, the guy who would replace the unit was busy and they didn?t have a replacement unit. I was very frustrated and mad?I chose Harker because I was told they could do it all in one day or we both wouldn?t have taken off work.  I could have just let my dog outside for a little while for him to look at the water heater.  I paid roughly $120 for this diagnostic test.

 

We then called to speak with a manager at Harker.  They tried to get someone to come back out that night and replace the water heater but were unable to.  They did have someone sent out first thing the next morning and took about $50 off the service call, which was appreciated but didn?t cover the amount of money we lost at work for missing part of both days.  This all could have been avoided by having their receptionist give accurate information.  There are a ton of places in Madison I could have called to have my water heater replaced and I chose Harker because I was told they could do it that same day and if they couldn't have replaced it that day, they should have said so and I would have made other arrangements. 



Update to Harkers repsonse:

At no time did they ever offer to have the heater replaced that evening for overtime rate or we would have easily paid it instead of taking more time off work.  We were told that they could try to get someone out that night but were unable to.  The only reason we okay'd them to come back the next morning is we needed it replaced as soon as possible.  We did not call later in the day-- it was still in the morning when we called.  And, obviously we know that you cannot carry all kinds of equipment around with you, but I was told that it would be replaced that night, so that is the fault of your receptionist to give me misinformation. They will try to write this so they sound like this was our fault for not knowing that they don't carry all the equipment, need licensed plumbers, etc., but we know exactly what was told to us on the phone and exactly how the situationw as handled and it was handled poorly.  We stand by our original reivew and will choose to use another company in the future.

"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

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.

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.

Signs your electric water heater is failing include inconsistent water temperature, reduced hot water supply, longer heating times, or discolored water (rusty or cloudy). Unusual noises like popping or rumbling suggest sediment buildup, while leaks or corrosion around the tank signal structural damage. If your unit is over 10 to 15 years old and experiencing frequent issues, it may be time to replace it.
