A Guide to Upgrading Your Home with Energy-Efficient HVAC Products

As the push for sustainability and energy efficiency continues to grow, many homeowners are exploring ways to reduce their carbon footprint and utility bills. One of the pivotal areas to focus on in this respect is the heating, ventilation, and air conditioning (HVAC) system. 

Given that HVAC systems are the biggest energy consumers in most homes, strategically upgrading your equipment can result in significant energy savings. In this post, we’ll explore the benefits of energy-efficient HVAC systems, delve into various energy-saving products, and provide some tips on how to maintain them for optimal performance.

Firstly, we’ll discuss the advantages of energy-efficient HVAC systems, including lower energy bills, improved indoor comfort, and environmental benefits. We’ll also explain some key efficiency ratings—like SEER, AFUE, and HSPF—that you need to understand when shopping for these systems.

But how do you identify the right energy-efficient HVAC products for your home? We’ll guide you on how to select the best furnaces, air conditioners, thermostats, and other equipment suited to your needs and climate. We’ll also offer insights on how technology, such as programmable thermostats and variable-speed motors, can boost your HVAC system’s energy efficiency.

Also, we’ll discuss the importance of professional installation in ensuring that your new energy-efficient system performs at its best. Proper installation is key to maximizing equipment efficiency and can save you from future costly repairs or early replacement.

Lastly, we’ll provide valuable tips on maintaining your HVAC system for continued energy efficiency. Regular maintenance, including routine professional check-ups and simple tasks you can do yourself, like changing filters, can significantly impact your equipment’s energy efficiency and lifespan.

The Benefits of Energy-Efficient HVAC Systems

Energy-efficient HVAC systems have gained popularity in recent years due in part to the numerous benefits they provide homeowners. These advantages go beyond energy savings and encompass various aspects of your home comfort:

Lower Energy Bills

One of the most significant benefits of energy-efficient HVAC systems is the potential to reduce monthly energy bills. These systems consume less energy during operation, resulting in lower costs for homeowners.

Improved Indoor Comfort

Energy-efficient equipment often provides more consistent temperature control throughout your home. With features like variable-speed motors and multi-stage heating or cooling, these systems can continuously adjust to maintain comfortable indoor conditions.

Environmental Impact

Choosing energy-efficient HVAC systems is an eco-friendly alternative that helps reduce carbon emissions and decrease our reliance on fossil fuels. By investing in energy-efficient devices, you’re contributing to a cleaner and more sustainable environment.

Key Efficiency Ratings for HVAC Systems

When shopping for energy-efficient HVAC products, it’s essential to understand these three crucial efficiency ratings:

SEER (Seasonal Energy Efficiency Ratio)

This rating is used for central air conditioners and heat pumps. A higher SEER rating indicates a more efficient system. In most parts of Canada, a minimum SEER rating of 13 or 14 is recommended; however, you can find systems with SEER ratings of 20 or higher, providing even greater efficiency.

AFUE (Annual Fuel Utilization Efficiency)

This rating applies to gas or oil-fired furnaces and boilers. AFUE indicates the percentage of fuel consumed that gets converted into actual heat. A higher AFUE rating means a more efficient furnace. Look for furnaces with an AFUE rating of 90% or higher for optimal energy efficiency.

HSPF (Heating Seasonal Performance Factor)

For heat pumps, the HSPF rating measures the system’s heating efficiency. A higher HSPF rating corresponds to a more efficient heating mode. Opt for heat pumps with an HSPF rating of 8.5 or higher for enhanced efficiency.

Choosing Energy-Efficient HVAC Products

With an understanding of efficiency ratings, you can now select the right HVAC products for your home. Here’s a closer look at some key energy-efficient equipment options:


When choosing an energy-efficient furnace, look for systems with a high AFUE rating, as well as features like variable-speed motors and multi-stage heating. These furnaces can adjust output according to the home’s heating needs, ensuring optimal efficiency.

Air Conditioners

Choose high-SEER air conditioners to reduce energy consumption during the cooling season. Look for features like variable-speed fans and multi-stage cooling to maintain consistent comfort with less energy use.

Thermostats and Controls

Programmable or smart thermostats can help optimize your HVAC system’s energy efficiency. By allowing you to preset temperature schedules and make automatic adjustments, these thermostats enable your heating and cooling equipment to operate more efficiently.

Importance of Professional Installation

Proper installation is crucial for energy-efficient HVAC systems to reach their full potential. Improper installation can lead to decreased efficiency, increased energy consumption, and a reduced lifespan for your equipment. Rely on professional installation services from a reputable company like Legacy Heating to ensure your HVAC system’s energy efficiency and longevity.

Maintaining Your Energy-Efficient HVAC System

Once your energy-efficient HVAC system is installed, regular maintenance is key to maintaining optimal performance and efficiency. Follow these tips to keep your system running smoothly:

Annual Check-Ups

Schedule yearly preventive maintenance appointments with a certified technician from Legacy Heating. Regular professional check-ups can help identify potential issues before they become severe, ensuring your system’s continued efficiency.

DIY Maintenance Tasks

In between professional check-ups, perform some simple maintenance tasks yourself. Clean or replace air filters regularly, inspect your outdoor unit for debris, and keep your vents clean and unobstructed.

Regular Duct and Ventilation Cleaning

Ensure your ductwork and ventilation system are clean and free of obstructions to maintain proper airflow and efficiency. Schedule regular duct cleaning every three to five years to keep your system in top shape.


Investing in energy-efficient HVAC products and diligently maintaining them can result in substantial energy savings and a more comfortable home environment. Understanding ratings like SEER, AFUE, and HSPF will help guide you in selecting the right energy-efficient equipment for your needs. Lastly, professional installation and maintenance services from a trusted provider like Legacy Heating are vital to ensuring your system achieves its full potential.
