What Makes an Air Conditioner High Efficient?

What Makes an Air Conditioner High Efficient

Over the years, many industries have developed higher standards of energy efficiency including the heating and cooling industry. Heating and cooling systems are more efficient than ever and new models are constantly coming out that consume less energy than older models. This progress greatly benefits consumers, as they now have the ability to choose highly efficient air conditioners or furnaces that keep energy costs down.

The important term for air conditioner efficiency is Seasonal Energy Efficiency Ratio (SEER). The efficiency of an air conditioner is determined by its SEER rating with a higher rating meaning the unit is more efficient.

There are two main developments in the heating and cooling industry that allowed for more energy efficient air conditioners and higher SEER ratings:

  1. R410A refrigerant – The old refrigerant that was used for years is called R22, but it doesn’t allow for very high SEER ratings. In 1991, R410A was invented as a more energy efficient alternative to R22. As mandated by the US government, all AC systems manufactured after January 1, 2010 have to use R410A.
  2. Two-Stage air conditioners – Two-stage air conditioning units have two levels of operation: a high setting for really hot days and a low setting for mild days. 80% of the time, the low setting is sufficient for your cooling needs. This allows the air conditioner to run more efficiently and produce more comfortable temperatures.

When it’s time to replace your system, taking advantage of these advances in technology can have a significant impact in lowering your energy costs. Two-stage air conditioners with SEER ratings of 16 or 18 are recommended for most homes because they are extremely efficient while also providing the most comfort.

If you feel like you are paying too much on your energy bills, you might have an inefficient unit or it could be caused by a number of other problems. The only way to really find out is by scheduling an energy audit with a professional. Your technician will assess your energy consumption and determine where you can improve your efficiency. Schedule an energy audit today to make sure you are optimizing your energy efficiency.

Three Signs It’s Time to Replace Insulation

Insulation is often something that is overlooked by many homeowners, an out of “out of sight, out of mind” situation. However, insulation is one of the most important components of a home. It’s what keeps you warm in the winter, and cool in the summer. It works with the HVAC system to ensure a comfortable indoor temperature year round. In newer homes, insulation should last for many years without needing to be replaced. However, here are three circumstances, especially in older homes, where new insulation should replace the old, or even added to existing insulation.

7 Places to Add Insulation in Your Home

As the seasons begin to change and it becomes colder, being well informed on how you can save money and save energy is imperative. Knowing where you can insulate your home is an easy way to help save energy and make your home more comfortable. Insulation works by trapping air pockets that moderate the migration of temperatures through walls, ceilings and floors, thus making them warmer in the winter and cooler in the summer. Without proper insulation and sealing, warm or cold air will leak out of your home, which wastes energy and forces your HVAC (Heating, Ventilating, and Air Conditioning) systems to work harder than necessary. The same concept goes with cool air during the summer. When your insulation is working properly, the temperatures in your home will remain more constant so that your HVAC systems are not running as much.
