"Harker Heating And Cooling is the best HVAC contractor we have ever worked with in 40 years. Their web site proudly says they are an “honest company with Midwestern values.” That is absolutely true. Their representative provided in-depth advice, answered our questions. and returned our messages. Their techs were knowledgeable, professional, careful, and friendly. They were on time, on call, and on budget. The service they provided for us over the years could not be better. So when the time finally came to replace our old furnace and A/C we selected them. Unfortunately, they encountered many unexpected problems installing our new equipment. Many more than they had anticipated for the job. But their representative pledged to address every one of them no matter how hard it was for them or how much of their time it took. And that is exactly what they did. No quibbling and no questions. They got the job done right. If you want an honest family contractor who stands behind what they do, and lives by those Midwestern values, then this is the company to hire. You will be glad you did.

"When Dave arrived and looked at the faucet and where it was located - he told me that it would be an additional $50 to cut a hole in the drywall which I said ok.  Then he went down to the basement to look for the water connection and he noticed that I had an old disconnected water softener.   He mentioned to me to me that I should have this water softener removed because it should be  because it potentially could cause an explosion.  Then he replaced the faucet and I asked him to give me an estimate on a 50gal new hot water heater and he did, gave me a written estimate and said that they would replace all the connections and hookups and I thought the estimate was totally fare.  Then as he was leaving, he said that he was not going to charge me for the cut into the drywall, and I was most appreciative.   He did a great job and I will definitely have him come back again.

"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 FAQs, answered by experts

Traditional gas or electric water heaters last an average of six to 11 years. However, with excellent maintenance, they can last up to 15 years. Heat pump water heaters, on the other hand, last an average of between 12 and 15 years and potentially longer with proper maintenance. In both cases, your home's water quality can be a determining factor regarding the lifespan of your water heater.

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

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.

If you are having trouble determining the right breaker size for your water heater, it is a great idea to contact an electrician near you to help. They can help you determine the best option for your home and install the circuit breaker for you, ensuring that you have all the proper permits and that your circuit breaker won’t overload, which could lead to fire and other damage.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.
