Frequently Asked Questions

How long does a hot water tank last?

Typically somewhere around 8 to 12 years, depending on water quality, usage and maintenance. If yours is in that range and starting to show problems, it's worth planning a replacement before it fails.

Is a tankless water heater worth it?

For many households it is: endless hot water and a smaller footprint. It depends on your gas line, venting and how you use hot water. We'll look at your setup and give you an honest recommendation.

Why does my water heater make popping noises?

Usually sediment built up in the bottom of the tank. Water trapped under the sediment boils and pops. Flushing can help on a newer tank. On an older tank it's often a sign it's near the end of its life.

My water heater is leaking. What do I do?

Shut off the cold water supply to the tank, turn the gas control to Off or Pilot (or switch off the breaker on an electric tank), and call 403-970-6988. We answer 24/7.
