How to Calculate EER HVAC

Energy Efficiency Ratios and the Right Air Purifier

If you’re like me, then there’s a pretty good chance that you’ve never calculated an Energy Efficiency Ratio (EER). Maybe some have never even heard of an EER? I know that anything involving a “calculation” can at once seem off-putting because of its inherent time-to-do-math moniker. However, understanding the reason for an Energy Efficiency Ratio is actually an important and useful bit of knowledge to have in regard to your home’s appliances. Plus, the math isn’t that hard to work out once you know how to calculate EER HVAC.

The EER Equation

Energy Efficiency Ratio looks to provide insight into how much power an appliance uses when plugged in, so that we can determine how much it will cost on our electric bill. There are two principles to understand when calculating an Energy Efficiency Ratio: 

  1. The output of an appliance’s energy, which is measured in BTUs.
  2. The input of electrical energy needed to run the appliance, which is measured in watts.

By dividing the output of energy by the input of electrical energy is what gives us an appliance’s Energy Efficiency Ratio. For example, if an air conditioner expels 12,000 BTUs of energy per hour and uses 1,000 watts of energy per hour, then its EER rating would be 12. Anything above 10.7 is considered sufficiently energy efficient and earns an Energy Star rating. This also means that your electrical bill will be less had you chosen an appliance with an EER below 10.7.

It is important to check the Energy Star ratings of all air-related appliances because they run constantly. They may play a big role in creating a comfortable home environment, but they could also play an even bigger role in your monthly bill assessments.

Air Purifier Importance

An air purifier is a good idea to have for cleaning out the air in your home. Using advanced HEPA technology filters, it can remove 99.7 percent of harmful airborne particulate matter that regularly circulates from room to room. Here are some of the specific benefits that come with using an air purifier:

    • Nasty odors neutralized: The odor caused by volatile organic compounds found in paints, aerosol sprays, upholstered furniture, or air fresheners can cause nausea, breathlessness, and even affect your cognitive functions. Also, when cooking at home, foul smells from leftover smoke, cooking oil, or spices can linger on for a bit too long.
    • Relief from asthma: Pollutants like pet dander, pollen, or dust mites can irritate your airways and cause breathing difficulty, especially for those who have asthma. Vacuuming can eliminate some of these toxins, but some also remain suspended in the air.
    • Reduces airborne diseases: The common cold and the flu are spread through tiny pathogens that float in the air. That’s why when someone in your household gets sick, others within the same domicile usually become infected as well.
    • Harmful chemicals eliminated: External pollutants like nitrogen dioxide and carbon monoxide are commonly detected in many homes. Beyond that, your home atmosphere could also be polluted with toxins from several household cleaning agents like bleach and aerosols. Being exposed to these chemicals in small amounts may be harmless, but routine exposure can possibly lead to serious health issues like cardiovascular or neurological disorders.
    • Removes risky asbestos and radon: Both asbestos and radon are very harmful to your lungs and can end up seriously destroying your body. Worst of all, they’re odorless and colorless, so detecting their presence is very tough. However, a HEPA air filter has no problem detecting these airborne noxious substances and doing away with them.
    • Helps with sleep: An air filter helps neutralize bacteria, dust mites, and other indoor allergens that can lead to sneezing, coughing, and congestion which could disrupt your sleep. Cleaner, purified air allows for much easier breathing when you’re ready to turn in for the evening.
