"I’ve used Anthony Heating & Plumbing for close to 8 years. They’ve replaced heating/A/C and water heater. They also have done some plumbing, fixed a sump pump issue, installed new PVC pipes for better flow and do annual general maintenance on my A/C and heater. They are punctual, friendly and clean. A few of my neighbors began using them."

"Terrific is an understatement! After being told by my HVAC company that they could not install a new hot water heater for 3 days, TJ at Metro Plumbing went above and beyond to make sure we had hot water before guests arrived the following day. He tracked down the unit we wanted, came to the house on a Saturday and he and his associate worked in tight quarters to the get the unit installed. It is no wonder he has been in business for 15 years! If you want a job done well at a fair price, I highly recommend KC Metro Plumbing! Thank you, TJ!"

"I had the owner Jacob over to the house on more than one occasion. He changed out my blower motor on my central air. He fixed my hot water heater on 2 separate occasions. He did a service call on my outside unit got it all cleaned up and functioning properly. Jake has came to the rescue when I clipped my thermostat wire with my weed eater. He installed a complete unit top to bottom including new line sets and proper wiring at a rental house for my sister. I highly recommend this company."

"Everest heating and cooling is my new go to hvac company!! My air unit went out Friday night around 10pm. I called multiple companies and they either wanted a small fortune or wouldn’t come out at all. I called Everest and talked to there hvac manager ray and he agreed to help us out not only did he come out immediately but he had my air conditioner up and going in a matter of minutes. He even called back the next day to make sure it was still working right. Everest will definitely be my go to service company."

Water Heaters FAQs, answered by experts

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.

The right way to vent a gas water heater is to have a pipe directly upward or slopes upward out of the house. Because hot air naturally rises, this type of venting will efficiently ensure that all gas moves out of the house. Your system may rely on fans or blowers as well.

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.
