"I needed to replace my parents' 40 year old AC Condenser and coil, and replace it with something that worked with the new furnace my father got installed four years prior. They were able to do the work requested, and also offered to redo the furance installation as the previous company installed it right on the basement floor where any backup/water could possibly get into the system. They were very prompt and showed up on time/on schedule. They were very upfront about costs and pricing and there were no last-minute price changes or hidden fees, which I appreciate. Work was done well and they ensured that everything worked before leaving the job site. The gentlemen working were very professional and understanding. I highly recommend them for anyone looking to replace their HVAC or to correct work that was previously poorly done."

"Steve was absolutely amazing to work with! Needed to replace my water heater and messaged him late Wednesday night, he got back with me early Thursday morning with the quote and came out that morning at 9:15 to replace the water heater. We got a great water heater, easy installation and the work was done very well. Steve is very knowledgeable and has such a great personality! You will NOT go wrong with hiring Steve! Thanks again for all your help, Steve."

"I purchased an electric tankless and pre-filter/softener directly from the manufacturer and started hunting for a plumber to install it. Now most all plumbers recommended against a tankless hot water heater, and Maplewood wasn't really any different in this regard. BUT, they listened to us, didn't treat us like idiots, and obliged us in our foolishness and they were really awesome. They did the job quickly and without a mess. Also, WE LOVE OUR NEW TANKLESS HOT WATER HEATER! I looked at our electric bill after 2 months (March-April) of using our Stiebel-Eltron E-tankless whole-house water heater unit, and the kW usage actually DECREASED from one year ago for those same two months. That’s right, there was no increase in our electric bill. As expected, our gas usage decreased. My wife was very worried because she often ended up talking to the plumber issuing the dire warnings and predictions about our silly misguided endeavor to get a tankless unit. Now, she couldn’t be happier. Tandem back-to-back showers all day long, if we wanted. Never ending hot water! Thank you Maplewood Plumbing for helping us!"

"I called Mr. Rooter because I had called another Plumbing company to come out the night before and they were a no show.  They were extremely friendly over the phone.  I called at approx 8AM and said they'd be able to come out by 11AM.  They called at about 9:30 to say someone was available to come out now and I said that was perfect.  They arrived at 10AM.

Jason was the plumber who arrived and he was very very friendly and professional.  I told him the problem and we discussed pricing up front.  I had a coupon which he said they would definitely honor.  He immediately got to work.  He wore footies over his shoes while in the house.  He worked diligently and answered all of my questions.  After about an hour and being certain the line was clear he cleaned up, we took care of payment which was exactly what was discussed beforehand, and he was on his way.

A very pleasant and hassle free experience.  I will definitely be calling Mr. Rooter for the Franklin County area again for any plumbing needs and would recommend them to anyone needing this kind of work.

The job also comes with a 30 day warranty which I thought was great and definitely put my mind at ease just in case something happened again."

"DP Plumbing and his crew went above and beyond to make sure that this job was done correctly and for the most reasonable price possible. They were professional efficient and got the job done as quickly as possible. I would highly recommend this company to my friends and family and to anyone else who wants a fair price and a professional team working at your home. I had other people come out and give me bids and none of them gave me the Comfort level that this company did. I just trusted them. I am actually having some other work done and have their card because I'm going to give them a call back for sure."

Water Heaters FAQs, answered by experts

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.

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.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.
