"The crew was on time (slightly ahead of schedule), through in their work, professional, cleaned up before/after, and highly responsive. Scheduling was done through text, as was the pre-consultation. Further, PorterHouse was price competitive, and offered me one of the better quotes/prices for a water heater replacement."

"I could not ask for a better experience from a plumbing contractor. The technician, Tony, was prompt, courteous, extremely quick in assessing the problem and getting my old water heater replaced. Valerie, who was the phone representative that took my initial call, was so helpful and kind to me. Not to mention, their pricing was very reasonable and more than competitive in our market. I will certainly be using Young Plumbing again for my home and I am going to spread the word to my neighbors and friends if they need a great plumber. Just a very satisfying experience on every aspect of their service."

"They started at 7:00 AM as planned were on time. The workers were very professional. They completed the installation by 6:00 PM at night. Installer said he smelled some,gas,by the water heater and replace the gas piping. Workers were very professional. Installed equipment looked awesome. They neatly routed the new suction and discharge piping as well as the pvc exhaust. They also redid the water heater piping and removed the old furnace vent piping. They,have a great warrantry compared to the other vendors who quoted. They,replaced the inlet duct assembly. Great job TDH. The equipment replaced a furnace and air conditioner that was 32 years old. They cleaned up and used temporary covers on the floor so as not to get it dirty. Hauled away old equipment. I highly recommend them if you are installing new/replacement HVAC. Brian who came over to quote the job and recommend the equipment was very good. I also liked that he still dos service calls. I thought overall it was a very good vale and am so glad I didn't wait until my HVAC to breakdown on a hot day or cold day as it was so old and not sounding good.

"I had Azrikam Heating (Azrikam The Price Is Right Heating) out today replace a part on my hot water tank and to take a look at my HVAC. 1) I am a new customer and even with other calls Bernard still came out to service my home 2) there is no bs. Any other person would tell you replace a unit when a part goes bad and the unit is 10 yrs old but no. Bernard looked at my system (paired water tanks), took pics for future reference, replaced the part and let me know that there is plenty of life left with both units. 3) Bernard is just a down to earth good person looking to give good services and guidance in his area of expertise. Put this company on your speed dial for home maintenance and repairs today."

"They were good. They tried to fix our existing furnace, but could not because of a problem that was caused by a previous plumbing issue. It was major hazard. This problem could've killed us due to its severity. They gave me a real good price and replaced the furnace and air conditioner. They were out doing work by 8:30am the next morning. They even provided us with space heaters while they worked on the furnace.  I was surprised with how fast they fixed everything. They cleaned up after themselves, and the workers were very polite."

"We actually had called Emanuel Brothers first since their name was on the water heater. But, after the amount of time and money they quoted us I decided to check Angie's. We had John come out and take a look and he told us he could do the same work for almost $800.00 less! I can't say I didn't have some trepidation. First, just how is it possible to do so much less work than we were told would be necessary (we had 2 water heaters. Neither of which worked after nearly 20 years, that had to be removed first to make room). And, for so much less. Emanuel Brothers were so perplexed by our situation that they had to call the boss to come out and explain everything to us. But, John had this "no problem" kinda attitude. Both refreshing and disconcerting. But, in just a couple of hours he had not only delivered a new water heater, he had the other 2 removed and the new one installed. And its been working flawlessly.

Water Heaters FAQs, answered by experts

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.

The amount of time it takes to replace an electric water heater will depend on the skill level of the individual who is replacing it. For example, if you replace it yourself–and you don’t have much experience–you can expect the project to take a full day. 

However, if you have a certified plumber or water heater contractor install your new water heater, it can take as little as 2 to 3 hours.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.

A well-maintained hot water recirculating pump can last 5 to 15 years. Pumps that run continuously may have a shorter lifespan than demand-controlled models. Hard water can reduce longevity by causing mineral buildup in the pump and pipes. Regular maintenance, such as cleaning or replacing filters, can extend the pump’s lifespan.
