A nationally-recognized industry organization named ACCA (Air Conditioning Contractors of America) provides a good resource on this topic. While Emerson is not affiliated with ACCA or otherwise endorsing this organization, this non-profit organization has been around for over 40 years and includes more than 60,000 professionals, along with 4,000 businesses in the indoor environment and energy services community.
Typically, air conditioning systems in the premium category are defined as having energy efficiency ratings that are 16 SEER or higher. Most in this category also have an important feature called “capacity modulation.”
The air conditioning and heat pump efficiency regulations that went into effect on January 1, 2015 will only affect new equipment, including both the indoor and outdoor units. General repairs to an existing system should not be affected unless the whole indoor or outdoor units are replaced. For example, the cost of replacing a part or general maintenance costs should not be affected.
This article attempts to explain three distinct references of the words “variable speed,” and why it is important to understand the context of this technology application. Many compressor manufactures have already launched variable speed products (or have plans to do so shortly) and this article should help frame your discussions in the best possible context.
Industry data indicates that 70 percent of consumers consistently purchase minimum efficiency and minimum featured HVAC systems and only 30 percent buy the higher featured and more efficient models. This is all true despite our sponsored research, which indicates that almost 70 percent of homeowners surveyed prefer systems that offer superior energy savings and comfort or created less impact on the environment.
Sometimes our cars, appliances, and even air conditioners make the strangest noises, but how do you know if they’re normal or if something might be wrong? The following are some tips about what sounds are normal and what indicates professional problem when it comes to your air conditioning unit.

Since the minimum efficiency regulation changed to 13 SEER in January 2006, most OEM systems now incorporate a thermostatic expansion valve (TXV) style metering device as the standard for air conditioning systems. It is now extremely important for the HVAC technician to understand the design and operation of this type of valve.
