Heating And Cooling Efficiency Ratings: What Do They Mean?

If you are considering replacing your HVAC system in Vaughan, you may have encountered various acronyms that represent the rating system for the efficiency of your appliance. These can be terribly confusing for the consumer. Let’s take a look at them so you can get an idea of what they mean and what you want to look for when you are researching your new system.

Your AC System: SEER Or EER?

If you are seeing SEER and EER ratings, these indicate the energy efficiency of an AC unit. SEER means Seasonal Energy Efficiency Ratio and EER means Energy Efficiency Ratio. So what’s the difference? Without going into technicalities, the simple answer is that EER takes more factors into consideration, such as cooling load and humidity removal, and may be a bit more comprehensive as it considers differing circumstances. Both give valuable information. Bottom line is the higher the rating, the more efficient the system. Although systems rated as high efficiency can cost more at the outset, they are usually well worth the extra cost in energy cost savings. Your local furnace repair professional in Vaughan can assist you in doing a cost comparison between a mid range system and a higher efficiency one.

Your Heat Pump And Efficiency

The Heating Season Performance Factor, or HSPF, will indicate the efficiency over the course of a season. It is the ratio of electricity consumed to the heat generated. The higher the ratio, the more efficient the system will be. Today’s most efficient heat pumps can realize almost a 10 in efficiency.

Your Gas Furnace And Efficiency

The Average Fuel Utilization Efficiency, or AFUE, is the ratio of consumed fossil fuel energy to heat output. This will show as a percentage of how much fuel usage actually becomes heat. The higher the number, the more efficient the system.

The Heating Seasonal Performance Factor, or HSPF, measures the heat output in BTUs compared to the watt hours of electricity used. Again, the higher the number, the more efficient the system.

Your Filters Have Their Own Acronym

Just in case you aren’t confused enough, the air filters used in your system have their own set of ratings. The Minimum Efficiency Reporting Value, or MERV, is the measurement of the filtering effectiveness of the air filter. Although a higher MERV rating will indicate that the filter is better at capturing small particles, be aware that they can also clog more quickly and cut airflow to the system. Your Vaughan furnace repair professional will always suggest you use the MERV rating that is recommended by the manufacturer of the system.

Now that you know what these ratings mean, it may have left you even more confused. By consulting with a professional HVAC contractor in Vaughan, you can make a more educated decision when it comes to replacing your heating or cooling system.
