Does Colorado HB 23-1161 ban gas furnaces or gas water heaters?

There is no blanket ban we can cite here; gas systems are still serviced and replaced where local code allows. Gas heating remains common in Denver, Aurora, and Arvada, and we continue to install, repair, and maintain these systems with upfront pricing. If HB 23-1161 affects your project, it would be through permits or efficiency rules during replacement, not an automatic prohibition. For water heaters, your technician will confirm allowed fuel types and permit steps during the on-site visit.

• Check your city’s permit office for any fuel-type limits.
• Get an on-site evaluation to confirm code compliance.
