Water Heater Repair and Maintenance in Boulder, CO

One of the most reliable machines in a household is the water heater. When they work, we enjoy hot water while hardly thinking about the water heater that produced it. We are able to maintain our personal hygiene with the help of these units by taking hot showers on a daily basis and cooking with on-demand hot water. Water heater failures, however, can have a significant impact on daily life.

As with any other machine, water heaters can develop issues over time. Typically, traditional water heaters require regular maintenance after around 5-6 years. They have an average lifespan of 8-12 years. The most common signs of a water heater that needs repair or replacement include rust in your water, pooling water around your water heater’s base, increased energy consumption, and long wait times for hot water. There comes a point at which repairing a water heater is no longer cost-effective. While an old water heater may still work, modern units offer significant energy savings, making replacement a worthwhile investment.

They Speak For Us

Bob came out to look at our swamp cooler and was remarkably helpful and professional. Not only did he give me a knowledgeable diagnosis, but he also taught me a lot in the process. We’ll be calling him for all future needs with our cooling system.


Dave Kaplan-Gomez and James Miltersen installed my new Tankless Water Heater. Both were polite and professional. Care was taken not to damage anything in my house which I really appreciated. I use Welzig for all my HVAC needs and highly recommend them.


Our 23-year-old A/C system ran out of “borrowed time” and became too difficult to continue maintaining. With great advice from Casey Welzig,, we replaced the old system with a Bryant Evolution A/C system. Max Loustaunau and Seth Bernhardt did an excellent job with removing the old system and installing the new one. Both of them are great to work with — very professional and very personable. We are really amazed at how much better the new system works!
