Choosing the right HVAC system is crucial for ensuring your home stays comfortable and operates efficiently. At Frontdoor, we understand better than anyone that your HVAC system is an investment in your home's future and in your quality of life.

Whether you're just exploring options or ready to make a decision, we're here to offer the support and information you need. That’s why we’ve compiled a comprehensive buying guide to help you find the best HVAC system for your home.

Understanding your HVAC system options

The first step to selecting an HVAC system is to know what your options are. Here, we'll dive into the specifics of three popular types of HVAC systems:

  1. Split Systems
  2. Hybrid Systems/Dual Fuel
  3. Packaged Heating and Air Systems

Read on to learn more about each system, their benefits, and considerations to help you make an informed choice.

Split systems

An example of split systems.

Split systems consist of two main parts: an outdoor unit, which houses the compressor and condenser, and an indoor unit, which contains the evaporator coils and air handler. This setup is favored for its efficiency and adaptability to different home layouts.


Highly efficient, leading to potential savings on energy bills.

Offers customizable solutions with zoning capabilities for targeted heating and cooling.


Installation can be challenging, requiring a significant amount of space and potentially increasing initial costs.

The need for both indoor and outdoor units may not suit every property layout.

Hybrid systems

An example of hybrid systems.

A hybrid system merges the efficiency of an electric heat pump with the robustness of a gas furnace, intelligently switching between the two to optimize energy use and comfort levels based on the external temperature.


Versatile energy usage can lower operational costs over time.

Provides an environmentally friendly heating solution by reducing reliance on fossil fuels.


The complexity of the system can lead to higher upfront costs and installation challenges.

Requires diligent maintenance to manage the dual components effectively.

Packaged heating & air systems

An example of packaged air systems.

Packaged systems consolidate all HVAC components into one outdoor unit, often installed on the roof or beside the house—simplifying installation and maintenance.


Space-efficient, with all components housed externally, freeing up indoor space.

Streamlines maintenance and installation, potentially reducing costs.


Outdoor installation exposes the system to weather, possibly impacting durability and performance.

May not offer the same level of efficiency as systems with indoor components, particularly in extreme climates.

What to consider when making your choice

Now that you know your options, let's narrow down the possibilities, focusing on two pivotal areas: your home's unique characteristics and your budget. By aligning these considerations with your lifestyle, you’ll ensure that your new HVAC system meets your daily needs and financial considerations.

Assessing Your Home’s Needs

Diving into the specifics of your home's layout, size, and environmental context can illuminate the path to the most suitable HVAC system. Here’s how to tailor your approach:

  • Home Size: The effectiveness of an HVAC system is closely tied to the size of your home. Incorrect sizing can lead to energy inefficiency and reduced comfort, highlighting the need for a system that aligns with your home's square footage.
  • Insulation Efficiency: Effective insulation plays a critical role in maintaining your home's temperature. It influences the type of HVAC system you need, affecting energy consumption and indoor comfort.
  • Climate Compatibility: The climate you live in dictates the most suitable HVAC system. Different systems perform better in certain weather conditions, making it essential to choose one that matches your local climate.
  • Lifestyle Alignment: Consider your family's daily habits and comfort preferences. A system with zoning capabilities might be ideal for homes where occupants have varied temperature preferences in different rooms.

Budgeting for Your New System

When budgeting for an HVAC system, focus on balancing upfront costs with long-term savings. High-efficiency systems may cost more initially but tend to lower energy bills significantly, making them worth the initial investment. Not sure where to start? A great first step is to chat with a Frontdoor HVAC Expert.

Consider the full lifecycle costs, including maintenance, repairs, and energy consumption. Sometimes, a system with a higher purchase price can lead to lower operating costs, offering savings and fewer hassles over time. Budgeting for your HVAC system is not just about the numbers; it's about making a smart investment that enhances comfort and saves on energy costs in the long run.
