How the Online Furnace Replacement Calculator Works

Estimating the cost of a gas furnace replacement involves detailed consideration of several factors to provide an accurate cost range. We used our 30+ years of experience in the residential HVAC industry and collaborated with other HVAC estimators to build this online estimating tool for our users to estimate their cost. We did so by using a step-by-step process that collects essential information about your location and cost of living, your existing furnace and HVAC system, and any other details that were needed to provide an accurate furnace replacement cost estimate online.

As you complete each question of the online estimator, the information, the calculator is working in the background to factor all those choices into the final estimated cost range. Once you’ve provided enough of the information to receive a cost range, the tool displays that estimated cost range to you.

Based on the information your provided the calculator will show you a low and high estimated cost that takes into consideration the cost of the new furnace, complete installation labor costs for removal of the old furnace, additional materials (ductwork, vents, thermostat, etc) needed, disposal, permits and inspection, etc. The replacement cost calculator also factors in the local labor rates and market prices in your area before the final estimates are displayed to you.
