"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.

"Avid pluming, what a great company ! My wife & I moved into our new house and after 2 huge water bills and some phone calls to our water company found out that the old toilet in the basement had a small leak. We contacted Patrick @ Avid plumbing. He was so friendly and showed sincere concern about our problem and put us on the appointment schedule the same week. With just about everyone in the service industry being short staffed right now I really appreciated him getting us scheduled. The day of the service plumber Art let us know when he would be arriving. Upon arrival he wore his booties over his shoes and wore a facemask as well. Art was so polite and listened patiently to our "story" and inspected the basement where the broken toilet is. He explained to us what our different options are regarding replacing this old toilet or fixing it. After we decided he worked diligently and gave us updates on his progress. When he was all finished the explained to us exactly what he did and how to monitor if a problem like this would happen again. He was such a nice young man and we are grateful for his concern. The service experience overall from the first phone call to the nice lady at the office to Art was exceptional . My wife & I would recommend him anytime to anyone who needs an excellent plumber. Thank you Art! Jurgen & Sandy Reinhold"

Water Heaters FAQs, answered by experts

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

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.

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.

Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.
