There appears to be some concern about what is really going to happen when the new, residential unitary air conditioning efficiency regulations go into effect later this year so we put together a list of questions and answers to help HVAC contractors keep current on what they need to know about these new standards.
Industry regulations can be complicated, but we’ve developed a list of terms from A to Z that will help contractors and facility managers better familiarize themselves.
Chiller efficiencies for air and water cooled chillers will be significantly increased in 2015. An addendum to ANSI/ASHRAE/IES Standard 90.1-2010, Energy Standard for Buildings Except Low-Rise Residential Buildings, continues the energy efficiency improvements that were implemented in 2010. The efficiency requirements increase overall annual energy savings by 8.3 percent compared to 2010.
Anyone who has ever addressed a crowded room would agree – comfort is critical to participation and creating an overall positive experience. Many studies have concluded that air conditioning is the most critical factor in providing a comfortable, climate controlled environment for learning.
The AC & Heating Connect staff did some research on the facts about ductless mini-split systems that might be of interest to contractors and distributors as they plan for the future growth of this segment.
There are many types of specialized HVAC technology used in commercial buildings and these are often much different from those terms used in common residential applications. We thought it would be helpful to provide a summary list of the various types of commercial air conditioning systems used in the US today.

I can remember when I first started in the HVACR industry; there were only 3 colors of refrigerant bottles in the back of the truck – green, purple and white. Along with these limited color options, I can remember using cardboard slide rules and calculators to determine charge amounts and system failure diagnosis.
