"They were very prompt, polite, and professional. My water heater was in a tricky spot . He ended up needing to disconnect a few things related to my furnace as well. They did it without charging me anything extra and When they were done, everything looked and worked great."

"Gabriel and his crew showed up when they said they would, and finished the work on schedule (new water heater installation). He came out the following day to look into an issue with the how water pipe going into the kitchen and didn't charge me, which I appreciated. I would call on them again for other plumbing work."

"Trio Heating and Air was an amazing company to work with! About a month ago I had Adrian come out and give me a quote on a new furnace for my home and he was so knowledgeable and easy to understand on what type of system I was needing for my home to lower my bill. We went with Trio and they scheduled the install to be done the very next day! Ever since then the furnace has been working so good they set the thermostat up just right I barely had to change it when it become cold outside. It was such an easy and fast process. I would defiantly recommend Trio Heating and Air for any for your heating and cooling needs!"

Water Heaters FAQs, answered by experts

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener. 

Your water heater's age can affect your homeowners' insurance policy. Many policies will ask how old the heater is when you first apply for a policy—and they may make you replace a model that's over 10 years old. 

Even if your policy permits you to have an older heater, it may significantly reduce the amount of protection available. If an older water heater suddenly leaks and causes damage to parts of your home, your policy may not cover it.

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.

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.
