"They were very good. I had two different residencies. So I used one of the Angie's List big deals at each location. They were on time, very prompt and professional. They were very easy to work with. I was very pleased. With regard to price, they were very reasonable. I didn’t feel like I was pressured to buy anything additional that I didn’t need. They told me exactly what was going on. Their responsiveness and punctuality were very good. I love the email system that they have. As soon as I buy a coupon, they send me an email and say let's schedule this. I love that because it's a very easy way to communicate without having to get calls all day. I would absolutely sue them again in the future. I have to give them extra kudos as well because I did have two residences. I had my Harrisonville address on record. I was waiting for them 6:10.9 to 6:15.1probably about 15-20 miles away from this address. I thought that they would be out here anytime. Then it dawned on me that I did not give them the updated address. So I called them immediately and said that it was my mistake for sending them the wrong address. They were very gracious in owning up to my mistake."

"We had Jones Air & Water come out to install filtration and replace a catalytic core system that we had installed to prevent descaling. In our situation, we had a high volume of Chlorine in the water that you could definitely smell and taste. The catalytic core system, didn't live up to the expectations and we still had to deal with a heavy scale build up noticeable on all of our faucets and with two Rinnai units for on demand hot water that raised concerns about what type of build up we were having on what we couldn't see. Everett came out and was very thorough in testing the water and then explaining a recommended solution. We finally decided on a dual media tank solution that Everett and JD installed that provides us with an efficient way to not only handle the Chlorine issue, but truly conditions the water and we're noticing all of the differences that Everett explained we should see. We are very satisfied with the whole process from the review of what our situation is, the recommended solution, the installation and the end result. We highly recommend using Everett for a water treatment solution."

"Overall, Rebath people are pleasant to work with. Brendan was a top notch craftsman, 'BJ' in office stayed in touch as work progressed. there were some problems with ordering product, receiving wrong product, miscommunication in scheduling, which delayed completion of job beyond our expectations. However job was completed to our satisfaction at last, and quality of product and of work are good.

"I received a phone call from Bo within an hour after completing my online request for help with my dryer. We made arrangements to meet the next day for him to look at the dryer and he was prompt and very courteous. When he took off the cover over the power cord he saw the problem immediately and told me that he could fix it quickly but he didn't have another power cord with him and it needed another small part. He was to return the next evening. He called me about an hour later the same day and told me he had the parts and would I mind if he came on out. It was fixed and my dryer was running fine. Very professional. I would call them again."

Water Heaters FAQs, answered by experts

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.

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

An average-sized empty water heater weighs around 150 pounds. Tankless water heaters are much lighter, weighing between 10 and 50 pounds. The smaller size and added convenience come at a price, though—tankless water heaters average about twice the price of their traditional counterparts.

Replacing facilitates energy savings, decreases repair frequency, and aligns with modern safety regulations, maximizing safety.

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