Quick Answer
In Colliers, WV, new furnace installation costs typically range from $2,635 to $5,610, including labor, permits, and full commissioning. Many homes here still rely on older oil systems or venting setups that aren’t energy efficient. A proper installation or fuel conversion requires load calculations, gas-line verification, and safety testing — not just swapping equipment.
How long does furnace installation take?
Most Colliers installations take 6–8 hours, though oil-to-gas conversions may extend to a full day for gas-line and vent updates.
What’s included in the installation cost?
Each Honest Fix installation includes labor, gas and vent safety testing, permits, commissioning, and a first-year tune-up under our Lifetime Trust Shield guarantee.
A Colliers Homeowner’s Story
A homeowner on Eldersville Road called after years of using an oil furnace that struggled to keep her home warm and cost a fortune to run. The system was noisy, and oil delivery had become unpredictable.
After a full inspection, we designed a natural gas conversion that included new venting, a high-efficiency gas furnace, and proper commissioning. Within weeks, she saw quieter performance and nearly 30% lower fuel costs.
Switching fuels isn’t just about saving money — it’s about comfort, safety, and reliability.
Why Installation Quality Matters in Colliers
Colliers homes often sit farther from utility lines, making energy reliability a top concern. Whether converting from oil or upgrading an older gas system, the quality of installation determines safety, efficiency, and long-term performance.
At Honest Fix, every installation includes:
- Manual J Load Calculation: Ensures your new furnace matches your home’s real heating demand.
- Fuel Line & Venting Inspection: Confirms gas-line sizing, vent safety, and draft quality before any equipment is installed.
- Sealed-Combustion Option: Ideal for rural or high-humidity basements — pulls air from outside for safer operation.
- Full Commissioning: Measures airflow, fuel pressure, and temperature rise for verified performance.
- Permit Filing: Handled through Brooke County — no shortcuts or uninspected conversions.
Your comfort system should be as efficient as it is safe — and in Colliers, both matter equally.

Step-by-Step: The Furnace Installation Process
- Site Review & Conversion Planning
We start with a Manual J load calculation, inspect your existing fuel and venting system, and verify gas-line capacity. For conversions, we plan new vent runs and handle permit applications with Brooke County. - Safe Removal of Existing Equipment
We safely disconnect and remove your oil or gas furnace, fuel lines, and old venting. Our team handles disposal and ensures environmental compliance for oil systems. - Furnace Setup & Connection
The new furnace is leveled, sealed to ductwork, and connected to the new gas supply and electrical system. Sealed-vent models draw air from outside, improving safety and efficiency. - Airflow & Gas Pressure Testing
We measure airflow at registers, test gas pressure, and verify all connections are leak-free before startup. - Commissioning & Safety Verification
This critical step confirms:- Correct temperature rise and static pressure
- Gas and voltage calibration
- CO and combustion safety levels
- Venting and draft operation
- Airflow balance
- Final Walkthrough
Once the system passes commissioning, we:- Register the manufacturer warranty
- Review your Lifetime Trust Shield coverage
- Show you system operation and filter maintenance
- Provide your commissioning and inspection documentation
Red Flags for Colliers Homeowners
- “You don’t need a new vent system.”
- “We can reuse your oil line — it’s fine.”
- “No permit needed for gas work.”
- “Commissioning takes too long.”
If safety testing, gas-line checks, or vent upgrades aren’t part of the plan, stop right there.
Repair Costs vs. Replacement
Furnace repair averages in Colliers:
- Minor repairs: $145 – $550
- Major repairs: $480 – $2,200 +
When major repairs begin to equal half the cost of a new installation — or when you’re running an outdated oil system — upgrading to a gas or high-efficiency furnace pays off quickly in comfort and reliability.
