New AC Units Vs. Old AC Units: Efficiency Comparison

When it comes to keeping your home cool in the Texas heat, the efficiency of your air conditioning unit plays a crucial role. With advancements in technology, new AC units offer better performance and energy savings than their older counterparts.

At Summit Air Conditioning & Heating, we’re dedicated to helping you understand the differences between older systems and modern, energy-efficient units. This guide will help you decide if upgrading your cooling system is the best choice for your home.

The Efficiency Of Old Air Conditioning Units

Old air conditioning units can still perform adequately, but they often lag regarding energy efficiency and reliability. Our experts are here to share some critical aspects of older systems.

Higher Energy Consumption

Due to outdated technology and natural wear and tear, older units typically consume more energy. This increased consumption causes higher utility bills and greater environmental impact.

Outdated Refrigerant Use

Many old units use R-22 refrigerant, also known as Freon™. This substance has been phased out due to its harmful effects on the ozone layer.

Finding and replacing this refrigerant is becoming more difficult and expensive. Systems that utilize R-22 refrigerants will eventually need replacement.

Frequent Maintenance And Repairs

Outdated systems usually need frequent air conditioner repair services and upkeep. As parts wear out or become obsolete, keeping an old unit running can be costly and inconvenient.

Inadequate Performance And Comfort

With age, the efficiency and performance of older systems decline. They may struggle to maintain consistent temperatures, leading to uneven cooling and reduced comfort in your home.

Are New AC Units More Efficient?

Modern air conditioners are built with advanced technology to improve performance and energy efficiency. There are a few notable ways they stand out compared to older systems.

Advanced Technology

New air conditioners incorporate the latest technology, such as variable speed motors and the ability to connect to smart thermostats. These features provide targeted temperature control and improved energy management.

Higher Energy Efficiency

New cooling units are built to meet stringent energy efficiency standards. Many come with high Seasonal Energy Efficiency Ratio2 (SEER2) ratings, indicating their superior energy performance.

Lower Environmental Impact

Newer systems use refrigerants with a lower environmental impact compared to Freon. This factor makes them a more sustainable choice for your home.

Adequate Reliability And Longevity

With proper maintenance, modern air conditioners are more reliable and have longer lifespans. They are designed to withstand the demands of various households, providing consistent long-term performance.

Energy Efficiency Comparison: Old vs. Modern AC Units

Understanding the differences in energy efficiency between old and new air conditioners is crucial when deciding whether to upgrade.

Here, we break down the factors that highlight efficiency improvements in modern systems compared to their older counterparts.

SEER2 Ratings

SEER2 ratings measure an air conditioner’s overall efficiency. AC units made after the start of 2023 will follow this new rating system, but older units may be measured with a SEER, the measurement that came before SEER2.

Regardless if your system’s efficiency is measured with SEER or SEER2, new air conditioners are often rated with a higher efficiency, which translates to less energy consumption and lower bills.

Operational Costs

New units operate more efficiently, which means they use less energy to cool your home. This efficiency can lead to significant reductions on regular energy bills. Over time, the financial savings can offset the primary investment in a new system.

Environmental Benefits

Switching to a modern, energy-efficient unit reduces your carbon footprint. New systems consume less electricity and use more sustainable refrigerants. These factors contribute to a greener home and community.
