Frequently Asked Questions
Are permits required to replace a furnace or water heater in Firestone, CO?
Yes. The Town of Firestone requires permits for many mechanical and plumbing projects, including residential furnace and AC replacements and tank-style water heater replacements. Tankless water heater projects and new gas piping may involve additional permit review. A licensed contractor can help confirm the requirements for your installation, coordinate inspections, and complete the work according to applicable local codes.
Do you repair and replace water heaters in Firestone?
Yes. Mountain Valley services both traditional tank and tankless water heaters in Firestone, including diagnostics, repairs, maintenance, replacements, and new installations. If your system is leaking, producing inconsistent hot water, making unusual noises, or nearing the end of its service life, our plumbers can inspect the unit and explain your repair and replacement options. Learn more about our water heater services.
Do you offer emergency plumbing or AC repair in Firestone?
We provide same-day plumbing and HVAC service during normal operating hours when scheduling allows, but Mountain Valley does not offer 24/7 emergency dispatch. For an active water leak, shut off the home’s main water supply if you can do so safely and call our office during business hours. If you smell gas or suspect a gas leak, leave the property and contact your gas utility or emergency services rather than attempting a repair yourself.
How much does a plumbing or HVAC service call cost in Firestone?
A standard service and diagnostic fee applies for a technician to evaluate the system. After the diagnostic, we explain the recommended work and provide a flat-rate quote before repairs begin. Final pricing depends on factors such as the type of repair, required parts, equipment condition, installation access, and any applicable permit requirements. Schedule an appointment to have your system evaluated.
Should I repair or replace my furnace, AC, or water heater?
The right choice depends on the equipment’s age, repair history, safety, efficiency, and the cost of the needed repair compared with its remaining service life. If a system is still in good condition, repair may be the more practical option; older or repeatedly failing equipment may be a stronger candidate for replacement. Our technicians can evaluate the system, explain both options, and identify any available utility rebates that may apply to qualifying replacement equipment.

Which utility rebates apply to Dacono HVAC upgrades?
Rebate eligibility for energy-efficient furnaces, central air conditioners, and heat pumps depends on which utility company supplies your home’s power and fuel. Dacono properties are served by either United Power or Xcel Energy depending on the specific neighborhood or street location. Our team verifies your utility territory prior to installation, and you can review general guidance on our utility rebates page.
