"They responded quickly, they were friendly and answered questions and got everything done. They also installed a whole house water filtration system plus the tank-less hot water heater. I had never tried HomeAdvisor before yet we were frustrated because the places we were given to have this work done weren't responding or showing up. We had questions, many, no hot water and within an hour we had a call back from Anderes Plumbing. This was on a Friday and Monday they were here checking out what they needed, plus setting up a day for two days later. It was a full days work. Everything was done that day except the filtration system needed a pump which they returned two days later to check on how everything was running with the pump in hand and had it installed in a heartbeat. By then we were already enjoying the hot water. It is a few weeks later now and everything is working well. If we need anymore work done we know who we are calling. Thank you Anderes Plumbing. LLC!"

"I don't have anything to compare this to, but my 30ish year old furnace went out during a cold snap. DSP came out in the evening to diagnose it, explained my options (spend $1,400 on a repair or just replace the unit). The technician even brought back electric heaters for me to use overnight (it was about 9 pm at that point). They had a furnace in stock and they replaced mine in the next day. It is a year later and everything is working great. They have even come back one time to show me how to properly use my new thermostat. I am very pleased with their service and would not hesitate to call them again.

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet.  I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."

Water Heaters FAQs, answered by experts

If you want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.

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.

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.

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home. 

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.
