Benefits of a High-Efficiency HVAC System

Your HVAC system is one of the most power-sucking appliances in your entire home or building. That’s why both residential and commercial property owners can benefit from upgrading to a high-efficiency HVAC system. Learn more about why installing a high-efficiency HVAC system is a smart decision.

What Is a High-Efficiency HVAC System?

A high-efficiency HVAC system is a unit that runs on less energy and operates at a higher efficiency than standard units. The Seasonal Energy Efficiency Ratio is a rating system that measures the efficiency of an HVAC’s air conditioning and heat pump cooling. 

Typically, units with a SEER rating of 13 and over are considered high-efficiency HVAC systems. Although these units can have higher price points initially, their efficiency can save you money throughout the years. By replacing your old system with a high-efficiency one, you are living a greener lifestyle. 

How Do You Calculate the Seasonal Energy Efficiency Ratio?

SEER is calculated by dividing the cooling output of a usual cooling season by the total amount of electricity used during this time frame. Manufacturers provide this calculation since you can’t necessarily determine it at home. 

What’s a Good Seasonal Energy Efficiency Ratio?

The higher the number, the more energy efficient your HVAC unit is. The ideal range is between 13 to 21, although some incredibly efficient units get a rating of up to 25. You can find the rating on the outside of your unit, often on a yellow sticker. 

When considering the SEER of your HVAC, remember that factors like the size of your space, your location, and your heating and cooling needs have an impact. When you have a large building to cool, a higher SEER may benefit you since it could help lower your monthly energy bill. Likewise, if you live somewhere hot and humid, you may want a more efficient HVAC system. 

What Are the Benefits of Having a High-Efficiency HVAC System?

As your current HVAC system continues to experience wear and tear, its efficiency is likely to dwindle. High-efficiency HVAC systems are designed to outperform old systems of the past. Here are some benefits you may see with a high-efficiency HVAC system:

Lower Energy Costs

Your old HVAC unit takes much more energy to run than brand-new high-efficiency models. Even though you’re going to spend a chunk of money on your new system, you could save more money on your monthly energy bill. Energy-efficient models tend to run less than old models, which means they use less power. 

Better Air Quality

A high-efficiency HVAC system delivers much better air quality. That’s because you’re getting a new air filter system. Additionally, the cracks that can develop in an old HVAC system could release carbon monoxide into your home or commercial building, which is dangerous for families and a huge liability for property owners. Even when you replace your HVAC system, always make sure your carbon monoxide detector is in working order. 


Getting a new system is a simple way to reduce your carbon footprint since many high-efficiency HVAC systems use significantly less energy. You can make an environmental impact with a new HVAC unit by reducing the natural resources you use.

Precise Temperature Control

Newer HVAC models tend to have smartphone integrations, meaning you can control the temperature of your home or commercial building with the touch of your phone or tablet. You can use your phone to change the temperature of your home while you’re at work or out of town. You can also set the temperature ahead of time so the building is comfortable when you walk through the door. Smart HVAC systems also give you remote control of your settings and make it easy to set exact temperatures. 

Less Noise

High-efficiency HVAC systems are much quieter than their older counterparts. Quiet HVAC systems are helpful for relaxing at home or reducing the complaints you get from office workers every time the air conditioning kicks on. Gone are the days of a constant buzzing and rattling from your unit. 

Higher Resale Value

When it’s time to sell your residential or commercial property, having a high-efficiency HVAC system can increase your value. Buyers want the convenience of already having a quality unit rather than installing it themselves. It’s a simple way to add another benefit that persuades more people to put in an offer for your property. 

Fewer Repair Costs

As HVAC systems get older, you may find yourself calling the service technician more often to make repairs. Replacing old parts can be more expensive than actually replacing the entire unit. With newer models, you’ll see significantly fewer electrical problems, which can help you save on repairs.

When purchasing a new HVAC system, you want to make sure it has the right capabilities for your home or building. Since there are so many new ones on the market, you should consider the following factors:

  • The size of the unit: A bigger unit may be able to heat or cool your space better, however, it also may require more power. Likewise, a smaller unit may be more economical but may need to run longer to fully heat or cool your space. Consult with a professional to determine the right size for your space. 
  • The SEER rating: High-efficiency units are 13 and above, though newer models are in the 20 to 25 range. If you live in a hotter climate, you should look for a unit with a higher rating. 
  • Programmable capabilities: Many HVAC units now have smartphone capabilities, though they may be more expensive. Consider if smartphone integration is something you want or need in your unit. 
  • Blower type: Blowers come in single speed, multi-speed, and variable speed. Since variable speed can make incremental adjustments, it’s the most efficient option.
