Furnace Installation in Castle Rock, CO
Your Guide to New Furnace Systems in the South Metro area
A new furnace is one of the most important investments you'll make in your home, one you'll rely on for warmth and safety for 15 to 25 years. Here in Castle Rock, that investment comes with unique challenges. Our high altitude and thinner air mean a standard "sea-level" installation won't work correctly. This can lead to inefficient operation, higher bills, and even premature system failure.
Rock Plumbing, Heating, Air & Electrical has been helping homeowners in the South Metro Denver area navigate these challenges for over two decades. Our family-owned company understands the specific, high-altitude adjustments needed for a safe and efficient furnace installation. We are committed to a transparent process and high-quality work, all backed by our 100% satisfaction guarantee.

Types of Furnaces
Gas Furnaces
Gas furnaces are the most popular choice for Castle Rock homeowners. They’re generally more efficient than oil furnaces and less expensive to operate than electric models because they run on natural gas—a cost-effective energy source in Colorado.
Benefits:
- Lower operating costs
- Reliable, consistent heat
- Widely available parts and service
Considerations:
- Requires proper ventilation to avoid carbon monoxide buildup
- Needs routine maintenance throughout its lifespan
For homeowners looking for an energy-efficient, budget-friendly option, gas furnaces are often the top choice.
Electric Furnaces
Electric furnaces are another common option. They are typically less expensive to purchase and install because they only require electricity, not natural gas piping or oil storage tanks.
Benefits:
- Lower upfront installation cost
- No risk of gas leaks
- Minimal maintenance needs
Considerations:
- Highest operating costs due to electricity usage
If you’re looking for a simple, clean-running system with a lower initial investment, an electric furnace may be a great fit. A Rock Plumbing, Heating, & Air Conditioning technician can help determine whether an electric model makes financial sense for your home.
Oil Furnaces
Though less common in Castle Rock than they once were, oil furnaces still offer valuable advantages—especially for homes not connected to natural gas lines.
Benefits:
- Strong, consistent heat output for large spaces
- Lower emissions than gas furnaces
- No carbon monoxide risk inside the home
Considerations:
- Requires an on-site oil storage tank and regular fuel deliveries
- Typically, more expensive fuel than natural gas
- Lowest efficiency rating of the three furnace types
Oil furnaces can still be an excellent option depending on your home’s setup and location. We can help you evaluate whether an oil furnace installation is a smart choice for your heating needs.
