Air Conditioner Energy Efficiency

In the market for a new AC? Air conditioner energy efficiency is a crucial consideration when it comes to both environmental sustainability and cost savings. Energy-efficient air conditioners are designed to use less electricity while maintaining optimal cooling performance. They achieve this through various technological advancements, such as improved insulation, variable speed compressors, and advanced airflow systems, which help ensure the cooling process is more efficient and less energy is wasted.

What Is SEER Rating?

One of the key metrics used to measure air conditioner energy efficiency is the Seasonal Energy Efficiency Ratio (SEER). A higher SEER rating indicates a more energy-efficient unit. This advancement translates into reduced electricity consumption and lower utility bills for consumers. In recent years, there has been a significant improvement in SEER ratings, with many models now exceeding 20 SEER or higher.

If you have questions about AC energy efficiency, John Stevenson Plumbing, Heating & Air Conditioning, Inc. can help. Our Mission Viejo AC installation experts can help you select the right cooling system to meet your energy efficiency goals and your budget.

Signs It's Time to Replace Your Air Conditioner

There are several signs that indicate it may be time to replace your air conditioner.

  • First, if your AC unit is more than 10-15 years old, it is likely becoming less efficient and may require frequent repairs. 
  • Second, if you notice a significant increase in your energy bills despite regular maintenance, it could be a sign of decreased efficiency. 
  • Third, if your AC struggles to cool your home or if there are inconsistent temperature variations, it may be a sign of a failing unit. 
  • Finally, if your air conditioner is emitting strange noises or producing unusual odors, it could indicate mechanical issues that warrant a replacement. 

When in doubt, consulting our Mission Viejo air conditioning replacement technicians can help you determine if it's time for a new air conditioner.

  • Why Isn't My Home Getting Warm Enough?
    There are a few reasons why your furnace may not be warming your home efficiently or evenly. One of the most common reasons is a leak in the ducting. If there is a small hole or the ducting is improperly installed, it could leak out warm air and cause the air pressure to drop and the system then provides inadequate heating. Additionally, dirty filters will also cause a restriction in airflow making the system work harder. This can lead to a broken system, which is why regularly changing and/or cleaning your air filters is so important.
