"My hot water heater was not repairable. They delivered and installed my new one in about 3 days. They cleaned up after themselves and were efficient and very nice. I would recommend them."

"Randy was just awesome! He was very knowledgeable and very kind. I called him around 10 am after having a new refrigerator delivered. I explained that I needed some help with the water line that connects to the ice maker/water dispenser. He explained over the phone what likely needed to happen and then told me that he would get back with me in a couple of hours. I gave him my address and info and sure enough--2 hours later he comes, takes a look at what I need done, went to the hardware store, and bought what was needed. He then came back and installed everything and spent a good deal of time talking to me about installing our gutters. He's very friendly and I would not hesitate to call him again if we need work done on our house or remodeling. The quality of service we received definitely exceeded the price we paid to hire him. Randy, if you see this, thanks again very much for all of your help today!"

"Someone came out the day before to see where the furnace was going to be installed. He suggested we go with a slightly larger unit for the size of our house, but we opted to go with the unit that was included in the deal.
Two men came out and installed the A/C and furnace. They told us they would be done with everything in about 4 hours, and kept pretty close to that. The furnace and A/C are both working perfectly so far.
We were mostly very happy with the company and the men who installed our units. There were only a couple minor annoyances. Our old furnace was incredibly rusty inside, and when they removed it from the house, they left a trail of rust and dirt from the basement to the front yard (including through our living room). They did not offer to clean it up, but left it for us to deal with. They also broke a light bulb in the basement and didn't get all the pieces cleaned up.

"If you want an immediate reply to your inquiry, professionalism, and friendly and quick scheduling of service, Anthony at DTS Plumbing is your guy. Anthony came to my house on a Monday to determine if I needed to replace my sump pump (I had seen slight amount of water following a huge storm) and possibly install a back-up battery unit. He recommended a new sump pump to replace my old system (original to the house), but advised me NOT to spend the extra money on a back-up battery unit. He could have easily have told me to spend that additional cash on a back-up, but instead won a customer for life with his honesty and integrity. My new sump pump was scheduled for install just two days after Anthony visited. It took him less than 10 minutes to complete the job, and I was immediately on my way back to work. I took advantage of the $395 special deal, and the unit has worked perfectly (and is so quiet I can barely hear it). Thank you, Anthony, for a superb job!"

Water Heaters FAQs, answered by experts

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

The average cost to replace a water heater is around $1,325, with a typical range of $900 to $1,800 for a standard replacement. The final price depends on the type of heater (tank vs. tankless), its size, fuel source (gas or electric), and the complexity of the installation. A simple one-to-one replacement will be on the lower end of the cost spectrum. However, if you are switching from one type of heater or energy source to another, you can expect labor costs to be significantly higher due to the extra work involved. It's also worth considering that while gas and electric heaters may have similar upfront costs, their long-term operating costs can differ based on local utility prices.

Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. 

If you’re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.

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.
