How Long Should Your HVAC System Last? Find Out!

What is Seasonal Energy Efficiency Ratio (SEER)?

SEER, or Seasonal Energy Efficiency Ratio, is a rating scale that measures an HVAC system’s energy efficiency. Used for central air conditioning and heat pumps, SEER finds expected energy efficiency for an entire season of the year, and even accounts for the HVAC system starting and stopping. In simple terms, SEER is used to gauge how much energy and money a unit needs to function over the year.

The higher the SEER rating for your HVAC system, the better. Most modern air conditioner’s scores typically range from 14 to 22. In fact, the US Department of Energy requires HVAC systems to have at least a 14 or 15 SEER rating, depending on the state. But how is it calculated?

HVAC systems are tested in a procedure called the AHRI (Air Conditioning, Heating, and Refrigeration Institute) Standard 210/240-2023, which subjects the system to a series of conditions to simulate different temperatures and humidity levels. The performance is measured and recorded, and the resulting data is then used for SEER calculations. The SEER rating itself is found by dividing the total number of BTUs (British thermal units) by the total amount of energy expended by the air conditioner in watt-hours. This provides an energy efficiency rating over the cooling season instead of just a moment in time.

The Update to SEER2

Starting in 2023, SEER was updated to a new calculation called SEER2. SEER2 is like its predecessor, though it reflects new testing standards that provide more accurate ratings.

In many cases, HVAC systems’ ratings won’t change very much, however efficiency ratings will be about 5% lower under SEER2 than SEER in most equipment.

SEER vs. Energy Efficiency Ratio (EER)

Another important rating you may see floating around is EER (Energy Efficiency Ratio). EER ratings measure how well an air conditioner performs and how much energy it uses when active. Like SEER, the higher the EER, the more energy efficient the system is. What is the difference between EER and SEER?

The primary difference between these two rating systems is SEER finds expected energy through the season, while EER only tests at a peak cooling time, specifically when the external temperature of 95°F. Finally, SEER accounts for your HVAC system stopping and starting, but EER assumes the systems runs at a continual, steady state.

This is not to say that EER is not a worthwhile rating system, but you should know the difference in these two ratings when considering an HVAC system.

Why Homeowners Should Care About SEER/SEER2 and EER

All these ratings, whether SEER, SEER2, or EER matter. Everyone wants to live in a comfortable space, and no one wants huge utility bills. Selecting an HVAC system with a higher SEER/SEER2 or EER rating means you will save money every month on utility bills and help the environment at the same time! With the right system, a higher investment in an efficient HVAC system will eventually pay for itself. These ratings are certainly a factor to consider for a future HVAC system.

What Size Air Conditioner Do I Need? It Depends on These Factors

Four primary factors should be considered when determining the size of your air conditioner: 

1. Square Footage 

The size of your space plays a significant role in determining the cooling capacity required. Larger areas will require a more powerful air conditioner to effectively cool the space. 

2. Climate 

The climate in your region affects the cooling load on your air conditioner. Hotter climates require higher cooling capacities to combat the heat. As This Old House notes, “A unit with a higher SEER (seasonal energy efficiency ratio) rating is beneficial in these areas. Milder climates might require less cooling power, meaning you can opt for a lower BTU (British Thermal Unit) A/C.” 

3. Insulation 

The quality and amount of insulation in your home impact how well it retains cool air. Proper insulation helps reduce the cooling load, which can influence the size of the air conditioner needed. However, if you have excessive windows or poor insulation, you’ll want to add about 10% to 15% to the amount of cooling capacity you’ll need. 

4. Sun Exposure 

Along with accounting for the number of windows, you’ll also want to note the direction they face. This is because it can affect the heat gain in your home. South and west-facing windows tend to let in more heat and may require a larger air conditioner. 

Calculating What Size Air Conditioner I Need 

Air conditioner capacity is weighed in tons, which is how much heat the unit can remove from a home in an hour. To determine the appropriate size of air conditioner for your home, you can use the following calculation: 

1. Calculate the square footage of the area to be cooled. 

2. Multiply the square footage by 25 to find the amount of BTUhs (British Thermal Units per hour) needed to cool the space 

3. Convert the BTUs into tons with 12,000 BTUhs = 1 ton.  

4. Adjust the calculated result based on the factors mentioned earlier. 

It’s important to note that this calculation provides a general estimate. For a more accurate assessment, it is recommended to consult with a professional HVAC technician, who can perform a thorough evaluation based on your specific circumstances.

Understanding the Refrigeration Cycle

The refrigeration cycle refers to the process by which an HVAC system cools the air. It is a continuous cycle that involves the circulation and transformation of a refrigerant—a chemical substance that absorbs and releases heat. The refrigeration cycle consists of four main components: the compressor, condenser, expansion valve, evaporator, and refrigerant.

1. Compressor

The compressor is the powerhouse of the refrigeration cycle. It pressurizes the refrigerant, increasing its temperature and pressure, and preparing it for the next stage.

2. Condenser

Next, the pressurized refrigerant reaches the condenser. This component dissipates heat from the refrigerant by transferring it to the surrounding air. As the refrigerant loses heat, it condenses and transforms from a gas to a liquid.

3. Expansion Valve

The refrigerant then passes through the expansion valve, which reduces the pressure. This sudden pressure drop causes the refrigerant to cool.

4. Evaporator

The cooled refrigerant enters the evaporator. As the refrigerant evaporates, it absorbs heat from the surrounding air, effectively cooling it down.

5. Refrigerant

Cooled air is then blown into our living spaces through vents or ducts. The refrigerant, now back in its gaseous state, returns to the compressor to begin the cycle anew.

Enhancing Energy Efficiency

Energy efficiency plays a crucial role in how well your HVAC system cools the summer heat. Proper maintenance is essential to ensure optimal performance and reduce energy consumption. Here are a few tips to improve the system’s efficiency:

• Change the air filters regularly to ensure proper air circulation and prevent dust buildup.
• Keep the outdoor unit clean and free from debris to enhance heat transfer.
• Seal any air leaks in your home to prevent cool air from escaping and hot air from entering.
• Use a programmable thermostat to regulate temperature settings and save energy when you’re not at home.

Know Your Gas and Electric Furnaces

Gas furnaces run on combustion. Using a gas line, valve, and igniter, the gas is ignited within the system and captured by a heat exchanger, which safely extracts and distributes heat throughout the home. Any exhaust or carbon monoxide created through the combustion is separated and released out of the furnace’s PVC pipe, thus keeping your home’s air clean of toxins.

Unlike a gas furnace, an electric furnace uses an air handler with heating coils to conduct auxiliary heat, which, combined with an electric heat pump, works to generate warmth throughout the home.

Gas vs Electric Furnace: Pros and Cons

Factors such as location, weather, energy efficiency, and pricing can impact which furnace will work best for your HVAC purposes. Here’s a look at the pros and cons of gas vs electric furnaces that homeowners can expect:

Gas Furnace

Pros

• Powerful Heating: Gas furnaces have a greater heating capacity than electric furnaces due to the high amount of heat they generate. In fact, gas furnaces are known to be energy efficient, and use less energy to quickly heat a home when cold weather strikes. Gas furnaces are a perfect choice for large homes or homes in northern states that endure heavy winters while keeping costs down.
• Energy Costs: Because gas furnaces rely on natural gas, they often generate more heat for less expense compared to electric furnaces since natural gas is a cheaper fuel source.

Cons

• Safety Risks: Due to its reliance on natural gas, homeowners with gas furnaces must be cautious of potential gas leaks within the home. There is also the possibility of carbon monoxide leaks.
• Installation Costs: On average, the average cost of a gas furnace is $2,100, with installation and labor costs adding $3,800 to $10,000. Combined with maintenance repairs that range anywhere from $300 to $1,200, gas furnaces can set back homeowners a significant amount of money

All Gas vs Electric Furnace: Pros and Cons

Between a gas vs electric furnace, gas furnaces work best in states that experience intense, cold weather.

Electric Furnace

Pros

• Safe Energy: Since electric furnaces only rely on electricity to heat the home, homeowners don’t have to worry about the risk of toxic substances leaking into the air.
• Cost-Efficient Machinery: Typically, electric furnaces cost about $835, and include additional installation fees ranging between $2,000 and $7,000. As a result, electric furnace owners can save a great deal of money when buying their HVAC system.

Cons

• Energy Bills: Though the machinery is less expensive, electric furnaces cause homeowners’ energy bills to spike during use. In wintertime, electric furnaces must work harder and longer to heat the whole home, causing more energy to be used. According to the U.S. Energy Information Administration, homeowners using electric furnaces in winter between 2022 and 2023 would spend around $1,359 on average, while gas furnace owners would spend about $930.
• Winter Strain: Electric furnaces take time to heat up the home. This limitation makes it difficult for electric furnaces to heat homes in heavy winter states in the north or Midwest, like Indiana or Wisconsin.

Energy Efficiency Ratio (EER) Explained

Before purchasing your next HVAC unit, it’s important to first look at its energy efficiency ratio. In the HVAC industry, an energy efficiency ratio (EER) is the standard measurement that calculates how well an air conditioner performs and how much energy it uses when active. The EER gives insight into which system performs the best with less energy, saving buyers money in energy and maintenance bills.  

You can calculate energy efficiency ratio with the following formula: 

EER = Output Capacity (BTU) / Power Input (Watts) 

Since it determines the energy needed to raise one pound of water by one Fahrenheit degree, this calculation has the closest accuracy for technicians and homeowners to evaluate HVAC systems. 

The higher EER rating a system has, the more efficient it is since higher rated conditioning units offer more cooler capabilities without extra expenses. However, it’s important to note that these measurements are most accurate if the system has the following temperature conditions during calculation: 

• External temperature: 95°F 
• Internal temperature: 80°F 
• Humidity level: 50%  

Checking your unit’s energy-efficiency ratio can help determine how well your HVAC system operates.

The Value of Energy Efficiency Ratio with HVAC Systems

Knowing how to calculate the HVAC unit’s energy efficiency ratio can give you a clear direction of which system will best suit you. Whether you’re a homeowner or business owner, creating a comfortable space for you and those in your space with lower energy costs can help save you expenses in the future.
