What are the most energy-efficient HVAC systems?

March 31, 2024

Whether you are looking for long-term savings on your utility bills or are interested in choosing the most sustainable HVAC system for your home or business, prioritizing efficiency is the key to achieving your goals.


Understanding Efficiency

Understanding the energy efficiency of your heating and cooling system is crucial for saving money on your electric bills

In the context of HVAC systems, energy efficiency identifies how effectively a system converts electricity or fuel (such as gas or oil) into climate-controlled air for circulation throughout a building. When electricity or fuel is converted and then circulated, the goal is to have as little energy loss as possible to obtain peak efficiency. Efficiency is primarily rated through the metrics SEER and EER. When looking for an energy-efficient system, you can easily rank systems by efficiency by looking for the systems with the highest ratings.


The Most Energy-Efficient HVAC System

It's important to research energy efficiency when it comes time to purchase a new heating or cooling system, such as a heat pump, for your home or business.

While the technology itself isn't new, the innovations in heat pump technology have propelled it ahead of its counterparts as the most efficient heating and cooling system. Understanding efficiency as a system’s ability to convert electric or fuel energy into hot and cool air explains how heat pumps generate more energy than they consume.


To simplify things, let's speak in terms of heat. A traditional system strives to convert an equal amount of energy in the form of electricity or fuel into heat energy. If this is achieved perfectly, that is 100% efficiency. However, a heat pump doesn't convert energy from one form to another. Heat pumps use electricity to gather heat from the outdoors (or the ground for geothermal heat pumps). Because heat pumps aren't limited to the 1:1 ratio, they can gather three to four (or more) times more heat energy to be used to warm a building. That's up to 400% efficiency.


One of the beneficial features of heat pump technology is that some systems have the capacity to heat and cool. When in cooling mode, air from inside the building (instead of outside) is gathered and transferred into energy. The resulting cool air is then circulated through the home or business, and any remaining heat is expelled outdoors.


Key Points about Heat Pumps

  • Heat pumps can be used in any climate within the United States and maintain efficiency. In extreme cold, systems will run slightly less efficiently.
  • Proper sizing of a heat pump is essential in reaching 300-400% efficiency.
  • Heat pumps are compatible with ducted and ductless homes.
  • Heat pumps can be zoned to allow for customized comfort in different rooms or floors of a home or business.
  • Heat pumps can last up to 25 years when well maintained.
  • Upkeep costs are low.
  • Heat pumps can be used in addition to other systems.
  • Heat pumps often have more rebates available because of their eco-friendliness.

Are there other options?

If heat pumps are not suitable for your needs or property, numerous other energy-efficient options exist. Evaluating SEER and EER ratings and consulting with HVAC professionals can help identify suitable alternatives. Optimal energy efficiency often involves combining a highly rated system with smart thermostat technology, adequate insulation, and diligent maintenance.

Boosting Efficiency

Selecting the correct HVAC system for your home or business is the key to boosting energy efficiency and saving on your energy bills.

When selecting an HVAC system, factors such as building size, age, insulation, and budget should all be considered. Professional HVAC consultation can ensure your system is properly sized and installed, leading to long-term energy savings. Additionally, implementing a few small DIY strategies can add an extra boost of efficiency to your system:

  • Seal air leaks
  • Weatherproof windows and doors
  • Replace air filters regularly
  • Clean vents and ductwork regularly
  • Optimize your thermostat schedule
  • Don't fidget with the thermostat dial
  • Use blinds to increase and decrease radiant heat as desired
  • Plant foliage around areas of the building you wish to keep cool
  • Ensure outdoor units are kept clean and unobstructed
  • Utilize smart energy monitors to track electricity and/or gas to identify potential improvements
