This guide by Hay’s Heating and Air Conditioning breaks down installation costs, factors that affect pricing, and ways to save money on a new furnace.
1. Factors Affecting Furnace Installation Costs
Furnace Type
The type of furnace you choose has a direct impact on installation costs:
- Gas Furnace: $3,000 – $7,500 (including installation). Best for colder climates with access to natural gas.
- Electric Furnace: $2,000 – $5,500. Lower upfront costs but higher electricity bills.

How to Choose the Right Furnace for Your Home
Furnace Size & BTU Rating
Choosing the correct furnace size is crucial for efficiency and cost-effectiveness.
- Oversized furnaces cycle on and off frequently, wasting energy and increasing wear.
- Undersized furnaces struggle to heat your home properly, leading to higher energy costs.
A professional HVAC technician calculates the required BTU rating based on home size, insulation, and climate.
Efficiency Rating (AFUE) & Energy Savings
Higher efficiency furnaces cost more upfront but save money in the long run.
- 80% AFUE (Standard Efficiency): Lower upfront cost, but higher monthly energy bills.
- 90%–98% AFUE (High Efficiency): More expensive initially but reduces long-term energy expenses.
Labor & Installation Complexity
Labor costs vary depending on:
- Whether ductwork needs to be replaced or modified.
- The complexity of venting and gas line installation.
- The ease of accessing the installation site.
Additional Features & Smart Technology
Modern furnaces come with advanced features that can affect installation costs:
- Variable-speed blowers: Improve airflow and efficiency.
- Smart thermostat compatibility: Increases comfort and reduces energy bills.
- Two-stage heating: Offers better temperature control and energy savings.
