SEER ratings help homeowners compare the cooling efficiency of air conditioners and heat pumps. A higher rating means the system can provide more cooling while using less electricity.

However, the highest rating isn’t always the best choice for every home. The system must also be the right size, properly installed, and suited to your comfort needs. Here are SEER ratings explained in simple terms so you can make a more informed choice.

Understanding HVAC SEER Ratings

SEER stands for Seasonal Energy Efficiency Ratio. It shows how efficiently an air conditioner or heat pump cools a home.

New systems use SEER2, which uses an updated testing method. Older systems may still have a SEER rating. Because the tests are different, SEER and SEER2 ratings can’t be compared directly.

How SEER Measures Cooling Efficiency

A SEER rating compares how much cooling a system provides over a typical cooling season with the electricity it uses. The result is a number such as 14, 16, or 18.

The higher the number, the more efficient the system is under standard test conditions. For example, a unit with a higher SEER2 rating should use less electricity than a lower-rated unit to provide the same amount of cooling.

The rating is useful for comparing equipment, but it doesn’t predict an exact electric bill. Omaha weather, thermostat settings, insulation, ductwork, and AC use will also affect energy costs.

Comparing Different SEER Ratings

Minimum efficiency standards prevent manufacturers from selling certain low-efficiency equipment. Beyond that minimum, homeowners can choose from several efficiency levels.

A standard-efficiency unit may have a lower purchase price. A high-efficiency system may cost more at first but use less electricity during the summer. The right balance depends on your home, budget, and how long you plan to keep the equipment.

What Higher Ratings Can Offer

Higher-rated air conditioners may provide:

• Lower energy use
• More even temperatures
• Better humidity control
• Quieter operation
• Fewer temperature changes

Many efficient systems can adjust how much cooling they provide. They don’t need to run at full power every time.

A high rating alone doesn’t guarantee comfort. The system must also be the right size and installed correctly.

Choosing An Efficient AC System

Choosing an energy-efficient HVAC system involves more than selecting the highest number on the label. A trained technician should first evaluate the home and calculate how much cooling it needs.

Thermal can help you compare equipment and explain the expected benefits of each option. Our professional air conditioning replacement service includes proper system selection and installation for your Omaha-area home.

Factors Beyond the SEER Rating

Before choosing a new heating and air system, consider:

• Your home’s size and layout
• The condition of the ductwork
• Insulation and air leaks
• Windows and sun exposure
• Indoor humidity
• Equipment warranties
• Purchase and operating costs

The system must be the right size. A small AC may run too much, while a large one may shut off too quickly. Both can make your home less comfortable.

Check available rebates and incentives before buying a new system. Some efficient systems may qualify for extra savings.
