How to Choose the Best High Efficiency HVAC System


Navigating the world of high-efficiency HVAC systems can be overwhelming, especially with the vast array of options available and limited time to make an informed decision. Since these units come with a higher upfront cost compared to standard heaters or air conditioners (due to their enhanced performance and more advanced installation requirements), you want to ensure you make the best choice. Carefully explore the factors to consider before diving into the purchase!

Energy Star Label

All high-efficiency HVAC systems should bear an Energy Star label. This, in conjunction with the unit's SEER rating, helps you guarantee you're buying an energy-efficient solution for your business or home.

SEER Rating

The Seasonal Energy Efficiency Ratio or SEER determines the performance efficiency of an HVAC unit. As heating and cooling technology has evolved, so have the requirements for what constitutes a good SEER number. SEER is calculated by dividing the cooling output of the HVAC unit by its energy used for the same season, typically summer.

Over the years, the minimum requirement for new HVAC systems has advanced. A SEER of 8 to 10 was once acceptable, but today, a heater or air conditioner must have a SEER of at least 14 to meet the minimum standard. The higher the SEER, the better, and high-efficiency HVAC systems deliver SEERs between 14 and 21.

Does this mean you need the highest SEER on the market? Not necessarily. Lower ratings between 14 and 20 are still sufficient if higher SEER units are out of your price range.


A high-efficiency HVAC system comes in various sizes to suit different buildings. Smaller units are less expensive and can fit properties with space constraints. However, smaller units have less heating and cooling power by default. Therefore, it will take them longer to generate enough heat or cooling to make your home comfortable.

Larger high-efficiency HVAC systems have higher heating and cooling power right off the bat. However, they take up more space and will be more expensive to install, purchase, and maintain.

Fan Speed Type

High-efficiency HVAC systems come equipped with a fan motor. Its primary responsibility is to move the conditioned air from the air conditioner or heat pump and send it throughout your home or commercial building. This makes the fan one of the most crucial parts of the entire operation.

Fans are available in multiple speed settings. A single-speed fan can only operate at one constant speed, no matter how ambient conditions change. Variable-speed fans can run faster or slower based on ambient conditions, allowing your home to feel cooler or warmer more quickly.

Multi-speed fans also offer you more versatility, offering two to three fan speeds. They are less advanced than variable-speed fans but still maintain optimized airflow for enhanced comfort.


Of course, we can't discuss the buying considerations when purchasing a new HVAC system without mentioning the price. Everyone's budget could ultimately be the deciding factor in the choice of system they'll buy.

On that note, high-efficiency HVAC systems are more expensive than most for several reasons. These eco-friendly heating and cooling solutions operate quietly, have longer-than-usual warranties, and offer excellent performance.

In addition to these features, installing a high-efficiency HVAC system is also more complex than a standard heating and cooling system. You'll need a generous budget to afford a high-efficiency HVAC.

Programming Options

The last consideration when making your choice is programmability. More and more high-efficiency HVAC units integrate with mobile devices like your smartphone, giving you more versatility in scheduling heating or cooling. That said, this feature further increases the cost of a high-efficiency HVAC system.

Remember, choosing the right high-efficiency HVAC system requires careful consideration of your specific needs and budget. By carefully evaluating the factors discussed above, you can make an informed decision that ensures your home or business stays comfortable and energy-efficient for years to come.
