That’s exactly why split system HVAC units are gaining serious traction among homeowners. These sleek, energy-conscious systems are rewriting the rules of home climate control—offering powerful performance without the bulk or noise of traditional setups.


Whether you're upgrading your outdated system or outfitting a new space, this article breaks down why split system HVACs are becoming the go-to choice in 2025—and what that means for your home, your budget, and your comfort.


Key Takeaways


  • Energy Efficiency: Modern HVAC systems offer higher SEER (Seasonal Energy Efficiency Ratio) ratings, leading to lower energy consumption and reduced utility bills.
  • Smart Technology: Integration with smart home systems allows for remote control and better energy management.
  • Environmental Impact: New refrigerants and eco-friendly designs contribute to a reduced carbon footprint.
  • Professional Installation: Proper installation by certified technicians is crucial for system performance and longevity.


Overview


Selecting the right HVAC system involves considering factors such as energy efficiency, reliability, cost, and suitability for your specific home needs. With the variety of options available in 2025, it's important to understand the features and benefits of top-rated systems to ensure optimal comfort and performance. 

Homeowners in London, Ontario should also consider their home’s insulation quality, local climate patterns, and future energy costs.


The best HVAC system is one that not only maintains comfortable temperatures year-round but also minimizes long-term maintenance expenses and energy usage. Consulting with professionals can help match your home's unique requirements with the most effective system available today.


Top HVAC Systems of 2025


1. High-Efficiency Central Air Systems


High-efficiency central air systems have become a preferred choice for homeowners in London, Ontario, due to their superior energy performance and consistent comfort delivery. These systems often boast Seasonal Energy Efficiency Ratio (SEER) ratings exceeding 20, indicating their capability to provide substantial cooling output for each unit of energy consumed.

 

For instance, the Carrier Infinity 24VNA4 model achieves a SEER rating of up to 24, making it one of the most efficient air conditioners on the market. 

The high SEER ratings translate to significant energy savings, especially during the hot and humid summers characteristic of the region. Homeowners report not only reduced energy bills but also appreciate the quiet operation and reliability of these systems. 

The integration of variable-speed compressors allows these units to adjust cooling output precisely, maintaining consistent indoor temperatures and enhancing overall comfort.


2. Smart HVAC Systems


Smart HVAC systems represent the convergence of heating and cooling technology with advanced automation and connectivity. These systems integrate seamlessly with home automation platforms, enabling users to control temperature settings remotely via smartphones or voice commands. Features like learning algorithms adapt to your schedule, optimizing comfort and efficiency.


Advanced AI algorithms in smart HVAC systems can predict energy needs with greater accuracy, adjusting operations proactively to maintain optimal indoor conditions. Integration with renewable energy sources, such as solar panels, further enhances their environmental friendliness. 

Voice-activated controls and real-time system monitoring provide users with convenience and peace of mind, ensuring that the system operates efficiently and alerts homeowners to any maintenance needs promptly.


3. Ductless Mini-Split Systems


Ductless mini-split systems offer a flexible and energy-efficient solution for homes without existing ductwork. These systems consist of an outdoor compressor unit and one or more indoor air-handling units, allowing for individual room control. They are particularly advantageous for retrofitting older homes or adding climate control to new additions without the need for extensive ductwork installation.


ENERGY STAR certified mini-split systems use up to 60% less energy than standard home electric radiators, making them a cost-effective choice for homeowners.

 The ability to control temperatures in individual rooms not only enhances comfort but also contributes to energy savings by allowing homeowners to heat or cool only the spaces in use. Additionally, the absence of ductwork eliminates energy losses associated with duct systems, further improving overall efficiency.


4. Geothermal Heat Pumps


Geothermal heat pumps utilize the stable temperatures underground to provide heating and cooling, offering a sustainable and energy-efficient alternative to traditional HVAC systems. These systems operate by transferring heat to or from the ground, depending on the season, through a series of buried pipes known as a ground loop.


Although the initial installation cost of geothermal systems is higher, they offer significant energy savings over time. According to the U.S. Department of Energy, geothermal heat pumps can save 50-70% on heating and cooling energy costs when compared to conventional systems. 

The longevity of these systems, with indoor components lasting up to 24 years and ground loops exceeding 50 years, further enhances their cost-effectiveness. Moreover, geothermal systems are environmentally friendly, reducing greenhouse gas emissions and reliance on fossil fuels.


5. Hybrid HVAC Systems


Hybrid HVAC systems, also known as dual-fuel systems, combine the efficiency of electric heat pumps with the power of traditional gas furnaces. This configuration allows the system to automatically switch between the two energy sources based on temperature conditions, optimizing energy use and comfort throughout the year.

During milder temperatures, the heat pump operates efficiently to provide heating or cooling. As outdoor temperatures drop, the system seamlessly transitions to the gas furnace to maintain indoor comfort. 

This adaptability ensures that homeowners benefit from the most cost-effective energy source available at any given time. Hybrid systems are particularly suitable for regions like London, Ontario, where temperature fluctuations are common, providing reliable performance and energy savings year-round.
