Energy Efficiency Ratings and Certifications

It is important to look for energy efficiency ratings when shopping for a sustainable HVAC system.

SEER2, or Seasonal Energy Efficiency Ratio, is your go-to metric in the HVAC world. It measures how efficiently an air conditioner converts electricity into cooling power. The higher the SEER, the more energy-efficient and eco-friendly your system is.

Then there’s ENERGY STARTM. This little blue label means a product meets strict energy efficiency guidelines set by the EPA. So, when shopping for a green HVAC system, look for a high SEER2 rating and that ENERGY STARTM label.

AFUE, or Annual Fuel Utilization Efficiency, is a measure of your furnace’s efficiency in converting fuel to energy. Think of it like this: if a furnace has an AFUE of 90%, that means 90% of the fuel is used to warm your home, while the other 10% goes up the chimney or flue. A higher AFUE rating equals more efficiency and less wasted energy.

HSPF2, or Heating Seasonal Performance Factor, is a measure of a heat pump’s efficiency over a heating season. It calculates the total heating output (in BTUs) divided by the total electricity used (in kilowatt-hours). A higher HSPF2 rating means the system is more energy-efficient, saving you money and reducing your carbon footprint.

How Eco-Friendly is Your HVAC?

When evaluating your home requirements for an eco-friendly HVAC system, consider the following to ensure you choose the most suitable option for your needs:

Assess Your Home’s Energy Efficiency

Before installing a new system, it’s wise to assess and improve your home’s energy efficiency. 

Look into insulation levels, window conditions, and air sealing in your home to minimize energy loss. An energy audit can be very helpful in identifying areas where improvements can be made.

Determine the Right Size

Choosing the correctly sized HVAC system is crucial. 

A system that’s too large will cycle on and off frequently, wasting energy – while one that’s too small won’t be effective. A professional HVAC contractor can help calculate the right size based on your home’s square footage, climate, insulation quality, and other factors.

Consider the Climate

The climate where you live can significantly impact the type of eco-friendly system that’s best for you. In areas, like Portland, with moderate temperatures, heat pumps are very efficient. However, in regions with extreme winters, a dual-fuel system or a high-efficiency furnace might be more appropriate.

Understand Different Systems and Their Benefits

Research various eco-friendly HVAC options such as heat pumps, high-efficiency air conditioners, and ductless mini-split systems. Each has its own set of benefits and suitability depending on the specifics of your home and climate.

Check for Rebates and Incentives

Look for any rebates, incentives, or tax credits available for installing energy-efficient systems. These can significantly offset the initial investment costs and make green HVAC options more affordable.

Prioritize Features

Decide on which features are important to you—for instance, if you want a smart thermostat, variable speed motors, or other advanced technologies that enhance efficiency and comfort.

Read Efficiency Ratings

Pay close attention to the SEER (for cooling systems), AFUE (for furnaces), and ENERGY STARTM certifications when comparing different models. These ratings will provide you with an estimation of the system’s energy usage and potential savings.

Choose a Reputable Installer

Select a qualified and experienced HVAC installer who is familiar with eco-friendly systems. Proper installation is key to ensuring that your system operates efficiently and effectively.

Evaluate Costs vs. Long-Term Savings

While eco-friendly HVAC systems may have higher upfront costs, calculate the long-term savings on utility bills. A more expensive system that is highly efficient could result in greater savings over its lifespan.

Size and Capacity

Matching an HVAC system size to your home needs is vitally important for several reasons. An improperly sized system can lead to inefficient operation, increased wear on the system’s components, higher utility bills, and a less comfortable living environment.

Load Calculation is a detailed analysis used to determine the right size of HVAC system for your home. It takes into account various factors such as:

  • Square footage of the home
  • Regional climate
  • Number and quality of windows
  • Insulation levels
  • Air infiltration rates
  • The home’s orientation
  • Heat-generating appliances
  • Occupancy

Is a Heat Pump Right for My Home?

Many homeowners in Portland are looking to install a heat pump. However, many Portland homes may not be ideally suited for standard heat pumps due to factors such as:
