"We were pleased to work with Greg Mair who came to.our house the night of Jan17, 2024 after our 14 year old furnace died. He reviewed our entire system and made recommendations that fit our needs correctly. He arranged for a new furnace to be installed the next day and provided us with space heaters to be used until the work was completed. We will definitely call on Greg for any future needs."

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.

Water Heaters FAQs, answered by experts

Going from a tank to a tankless water heater is one of the most effective ways to lower your utility bills. The switch also frees up more space and ensures a consistent hot water supply, as the water is heated on an as-needed basis. It costs between $5,400 and $7,400 to install a new tankless water heater. Most installation companies will also help dispose of your old water tank.

Unless you have previous plumbing experience or extensive experience with water heaters, you should avoid replacing your electric water heater yourself. This process involves disconnecting wiring and parts from the old water heater and reinstalling them onto the new one, among other difficult tasks. This job is best left to the pros to make sure that everything is connected correctly to avoid serious leaks or malfunctions.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.

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.

Every type of water heater has its advantages and disadvantages. Understanding those can help you decide the best type for your situation and budget. 

Pros

  • Safer than gas or propane

  • Doesn’t require extensive venting systems

  • Lower upfront costs

  • Simpler to operate

  • No pilot light

  • Easier installation

  • More efficient heating than gas models

  • Available as point-of-use (POU) and whole-house units

Cons

  • Slower to heat water

  • Longer recovery time

  • Possibly higher operating costs

  • Doesn’t work during a power outage

  • Costs can increase without a 240-volt connection
