Although easy to overlook, an effective HVAC system is a key part of an energy-efficient home. If your unit isn’t performing as it should be, it may be time to learn about more efficient models with the help of professional HVAC services in Marlborough, CT. SM Mechanical Services LLC is ready to help homeowners compare new units or repair old ones to ensure their homes are as energy-efficient as possible.
Demystifying the ratings used to rank different models is a great first step toward saving money and enjoying a more comfortable home. All homeowners should understand a few critical performance measures to make informed decisions about interior climate control.
What Are the Different Ratings?
The measurements used to rank cooling and heating systems can be confusing, but there are only three main ones to consider. Homeowners will benefit from understanding these basic ratios when deciding whether to repair or replace their current systems. They can also be useful tools for evaluating the infrastructure of a potential new home.
SEER (Seasonal Energy Efficiency Ratio)
The SEER is a long-term measure of a unit’s effectiveness over an entire cooling season. It is calculated by measuring the cooling output and dividing it by the amount of energy used. In residential units, the SEER can be up to 20; the higher the number, the better.
In southern states with warmer climates, the minimum SEER rating on new units is 14, while here in Marlborough, CT, the minimum is 13. Old systems can register at nearly half that, so an upgrade can quickly make huge differences to your power bill and overall home comfort.
This measurement is an important marker of cooling capacity because it accounts for the entire season, providing a comprehensive view of your HVAC’s performance over time.
EER (Energy Efficiency Ratio)
Like the SEER, the EER reflects your unit’s cooling abilities. However, the EER is calculated using a specific outside temperature instead of taking measurements over an entire season. The cooling output at a given external temperature is divided by the energy usage required to function at that temperature.
This is particularly relevant for very hot climates, where a unit may have to run at full volume for extended periods during high external temperatures. Although this ratio is not as commonly seen in heating applications, it does measure heat pump performance.
HSPF (Heating Seasonal Performance Factor)
The HSPF provides homeowners with an estimate of the HVAC’s heating capabilities. To get this number, one must divide the output from the heating pump by the amount of electricity required to run it. Residential heat pumps are typically available in the 8.2-10 HSPF range, with higher ratios performing better.
For homeowners using fuel to heat their homes, the AFUE (Annual Fuel Utilization Efficiency) is a similar measurement that determines how much fuel is wasted during the heating process. In modern units, this number should be as close to 100% as possible (as this number represents the percentage of fuel that is burned and used effectively, while any remainder indicates waste).
Top-of-the-line residential models today operate at around 98.5%, but older furnaces can measure as poorly as 50%. That means half of the fuel used in heating your home is wasted, and upgrading an old unit could almost double its efficiency. This will reduce your gas bill and often make your home warmer.
Which Ratings To Prioritize in Marlborough, CT
Before purchasing a new HVAC unit, consider each of the three key ratios. It is typically best to find the models within your price range that offer the highest possible rankings in each category before comparing the differences in individual ratings.
It may be beneficial to prioritize heating or cooling to suit the needs of your climate. In Marlborough, CT, this could mean selecting a unit with a higher HSPF rating even if its SEER is slightly lower than other models you may be considering. This will save you money during the long winters when your heating will be on for more months than your air conditioning might be.
Keep in mind that the minimum ratings for new systems are regulated, so a slightly lower number in one area does not mean the unit will perform badly.
Why Does Efficiency Matter?
Homeowners don’t always understand why installing and maintaining an efficient HVAC is so important. This household improvement can save you time, money, and stress. It also lowers your ecological footprint by reducing your energy usage and helps create the most comfortable home possible.
Lower Your Bills
Generally, the less energy your HVAC requires to modulate the climate in your house, the cheaper your electricity bill will be. This is especially important in places with extreme summers or winters where your HVAC might run at full blast for long stretches, becoming costly.
Further, while more advanced units cost more upfront, they tend to last longer and require fewer repairs over their lifetime, saving you money in the long run. In some places, these units also qualify for financial incentives such as tax rebates.
Create a More Comfortable Home
A reliable and effective HVAC unit is indispensable in terms of home comfort. During the hottest and coldest months, an efficient unit can quickly get your home to your preferred temperature and keep it there for extended periods without breaking the bank.
These models also tend to operate quieter, causing less disruption when adjusting the temperature of your home. As long as you maintain them properly, they may even offer better air quality than older options.
