If you’re researching “cost to replace HVAC unit“, it can vary depending on factors like system size, efficiency, and installation requirements. Upgrading to a new HVAC system not only ensures comfort but also improves energy efficiency in your home. Understanding the costs and what influences them is essential when planning your replacement.
On average, the cost to replace an HVAC unit depends on several factors, including the type of system you’re installing, the size of your home, and the complexity of the installation. While it can vary widely, here are some quick points to keep in mind:
- The cost of a new HVAC system typically ranges from $5,000 to $12,000.
- Geothermal heat pump systems can have higher upfront costs, often between $15,000 and $30,000, but offer exceptional energy efficiency.
- Installation and material costs can make up a significant portion of the overall expense.
If you’re currently exploring options for a new HVAC system, Genz-Ryan makes it easy with our Instant HVAC Quote tool. But before we show you how it works, let’s break down the factors influencing HVAC replacement costs.
💵 What Determines The Cost To Replace An HVAC Unit?
The average cost to replace an HVAC unit can feel a bit steep, but several factors influence the final price. From the type of system you choose to installation complexity, here’s what you need to consider.

Type of HVAC System
The type of HVAC unit you select plays a major role in determining replacement costs. Below are common options and their average costs:
- Central Air Conditioning Systems: Central AC units are among the most common choices. Replacing a standard central air system typically costs between $5,000 to $10,000, including installation.
- Heat Pump Systems: Air-source heat pump systems, which can both heat and cool your home, generally range from $5,000 to $12,000. More energy-efficient options, like ductless mini-splits, may come in on the higher end of this range.
- Geothermal Heat Pump Systems: Geothermal systems are a top-tier option for energy efficiency, but they come with a hefty upfront price tag. Costs average between $15,000 to $30,000 due to the excavation and ground loop installation required.
- Furnace and AC Combos: Many homeowners opt for a combined furnace and AC unit for comprehensive year-round comfort. Together, this setup typically costs $8,000 to $15,000.
One of the best ways to figure out which system is right for your home is by consulting professional HVAC contractors like the trusted team at Genz-Ryan.
System Size and Output
Is your HVAC system sized appropriately for your home? All systems have a measured output called BTU (British Thermal Unit), which reflects their ability to heat or cool. Larger homes usually require higher-capacity systems, which generally cost more.
Oversized systems waste energy, while undersized systems struggle to regulate temperature efficiently. This is why working with knowledgeable HVAC professionals matters so much—they ensure the right size system is selected for your home.
Installation Complexity
Some HVAC installations are more straightforward, while others may require additional work, like removing an old system, modifying ductwork, or accommodating multi-story buildings. These added complexities can lead to higher labor costs.
For example:
- Old System Removal: Demolishing and hauling away aging equipment can increase the overall replacement cost.
- Ductwork Modifications: If your ductwork is outdated, poorly insulated, or in need of repairs, additional labor and materials will add to your bill.
- Accessibility Issues: Installing an HVAC system in a multi-story home or older property may require specialized planning and equipment.

Add-On Features
When you invest in a new HVAC system, it’s an ideal time to consider add-ons that improve air quality or energy efficiency:
- UV air purifiers or HEPA filters
- Smart thermostats for better temperature control
- Zoning systems for personalized comfort
Including these features will influence the total installation cost but can contribute to long-term savings and comfort.
Energy Efficiency Ratings
Energy-efficient systems often have higher upfront costs but pay off in the long term through lower utility bills. Look for units with high SEER (Seasonal Energy Efficiency Ratio) ratings for cooling systems or AFUE (Annual Fuel Utilization Efficiency) ratings for furnaces. The more efficient your system is, the lower your energy costs will be over time.
✅ 5-Step Guide to Choosing an HVAC Replacement
When it comes to selecting a new HVAC system, making an informed choice is key. Here’s a helpful step-by-step guide:
- Assess Your Needs: Start by evaluating your current HVAC system. What’s not working? Are there hot or cold spots in your home? Understanding your needs will help you narrow down the type of HVAC unit required.
- Set Your Budget: Consider both the upfront costs and the potential energy savings over time. Ask yourself whether you want to prioritize energy efficiency or affordability initially.
- Research System Options: Research the different types of HVAC systems, from central air conditioners to geothermal heat pumps. A professional can also guide you toward the best option based on your home’s layout and requirements.
- Consult with HVAC Professionals: Don’t go it alone. Book consultations with licensed HVAC professionals who can provide recommendations, clear estimates, and explanations of costs.
