Prices to replace a ventless fireplace with a vented unit vary widely depending on the chosen unit, venting requirements, and labor. The main cost drivers include the new fireplace, venting materials, gas lines or electrical work, permits, and disposal. This guide presents practical price ranges in USD and includes per unit and total estimates to help budget planning.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| New vented fireplace unit | 1,200 | 3,000 | 6,500 | Gas or electric vented models; higher efficiency adds cost |
| Venting system and materials | 1,000 | 2,000 | 3,000 | Chimney pipes, vent cap, fireplaces flue pipes |
| Gas line or electrical work | 600 | 1,800 | 4,000 | Gas line runs or 110V/240V circuit upgrades as needed |
| Removal of ventless unit and cleanup | 150 | 400 | 800 | Disposal fees for ventless components |
| Permits and inspections | 50 | 350 | 1,000 | Local permit and final inspection costs |
| Labor and installation | 2,000 | 3,500 | 5,500 | Crew time including rough-in and finishing |
| Total project cost | 4,000 | 9,000 | 20,000 | Assumes moderate-to-complex installation |
Overview Of Costs
Typical price range for replacing ventless with a vented fireplace is approximately 4,000 to 20,000, depending on unit choice, venting complexity, and local labor rates. Per-unit costs often include a new vented fireplace unit at 1,200–6,500, plus 1,000–3,000 for venting and 600–4,000 for gas or electrical work. Assumptions: standard living space, clear access, and no major structural modifications.
Cost Breakdown
The project blends equipment, labor, and compliance. The table shows what typically drives the total and where costs concentrate.
| Materials | Labor | Permits | Delivery/Disposal | Warranty | Taxes |
|---|---|---|---|---|---|
| Ventless unit removal and vented unit supply | 2,000–3,500 hours | 50–350 | 100–300 | Optional | 6–9% |

What Drives Price
Cost drivers include the type of vented fireplace (gas vs electric), venting complexity, and the condition of the existing chimney or exterior vent. New vented gas fireplaces usually cost more upfront but may offer better performance. Venting length and routing affect both materials and labor; longer runs or dramatic changes in direction increase price. A complex install with added hearth work or electrical panel upgrades will push totals higher.
Ways To Save
Several strategies can reduce project cost without compromising safety. Consider selecting a standard-size, widely available model to minimize custom fabrication. Combining removal of ventless components with the vented install in a single visit lowers labor overhead. Scheduling during off-peak seasons can also yield lower labor rates. Plan for permitting early to avoid delays and last‑minute fees.
Regional Price Differences
Prices vary by region due to labor markets, fuel costs, and permit fees. In the Northeast, expect higher labor and permit costs; the Midwest may offer mid-range pricing; the South often shows lower installations but higher venting material costs in some markets. On average, regional deltas can be ±15% to ±25% from the national average, depending on local codes and crew availability.
Labor & Installation Time
Labor time depends on vent routing, existing chimney configuration, and space access. A straightforward conversion might require 8–16 hours; a complex vent chase or exterior venting could take 20–40 hours. Labor costs commonly account for one-third to one-half of total project price.
Permits, Codes & Rebates
Permits typically range from 50 to 1,000, with inspections adding a small fee in many jurisdictions. Local rebates or utility programs may apply if the fireplace is energy efficient or uses alternative fuels. Check local building departments for exact requirements before purchase and scheduling.
