How Much Does a Heating System Replacement Cost?

How much does a heating system replacement cost? On average, homeowners can expect to pay between $3,000 and $15,000, depending on the type of system, home size, and installation needs. A simple furnace replacement may be on the lower end, while a complete HVAC system replacement falls on the higher side. Efficiency ratings, labor, and whether you bundle upgrades like a water heater replacement also affect the total cost. In this guide, we’ll break down the main factors, explore cost ranges, and show you how Milehi HVAC can help you make the best decision for your comfort and budget.

Understanding Heating System Replacement

Before exploring detailed costs, it’s important to understand what heating replacement means. Replacing a heating system involves removing the old unit whether a furnace, boiler, or heat pump and installing a new, more efficient system. It’s not just about swapping equipment; it often requires ductwork adjustments, thermostat upgrades, and sometimes paired services like water heater replacement.

Factors That Affect Heating Replacement Cost

When asking, How much does a heating system replacement cost?, several factors come into play.

Size of the Home

A larger home requires a system with higher BTU output, which directly increases heating replacement cost.

Type of Heating System

• Gas Furnaces – Reliable, widely used, and usually mid-range in cost. The furnace replacement price varies depending on efficiency.
  
  

• Electric Furnaces – Lower upfront costs, but higher operating expenses.
  
  

• Heat Pumps – More expensive initially but provide both heating and cooling.
  
  

• Boilers – Typically come with higher replace heating cost, especially in older homes.
  
  

Efficiency Ratings

High-efficiency systems raise the HVAC replacement cost initially but reduce energy bills over time.

Labor and Installation

Professional installation impacts your total costs. With Milehi HVAC, you get certified technicians, accurate system sizing, and long-term peace of mind.

Breaking Down Heating Replacement Cost

Furnace Replacement Price

The average furnace replacement price ranges from $3,000 to $7,500, depending on brand, size, and efficiency rating.

HVAC Replacement Cost

For combined heating and cooling systems, the HVAC replacement cost can range from $7,500 to $15,000. While this is more expensive, replacing both at once saves money in labor and ensures system balance.

Replace Heating Cost for Older Homes

Older homes may require new ductwork, venting upgrades, or asbestos removal, increasing the replace heating cost.

The Role of Water Heater Replacement

Upgrading your heating system is the perfect time to also consider water heater replacement.

• Efficiency Boost – Replacing both ensures maximum savings.

• Labor Savings – Bundling projects reduces installation costs.

• Home Value – Increases your property’s resale appeal.

At Milehi HVAC, we often recommend evaluating heating and hot water systems together for best results.

Comparing Heating System Options

Gas vs. Electric Furnaces

Gas furnaces may have a higher furnace replacement price, but they’re cheaper to operate long term. Electric furnaces are more affordable initially but lead to higher energy bills.

Heat Pumps and HVAC Systems

The HVAC replacement cost for heat pumps is higher but offers year-round efficiency since they also provide cooling.

Boilers and Radiant Heat

Boilers have a higher replace heating cost, but they deliver steady, comfortable warmth in homes without ductwork.
