Save 20% or more on HVAC. It’s important now more than ever for a sustainable future! 

Optimizing PTAC units with a “smart” device is a fast, easy, and cost-effective way to achieve Commercial HVAC Energy Savings. A Packaged Terminal Air Conditioner is a type of self-contained heating and air conditioning system commonly found in: Hotels, Motels, Senior Housing Facilities, Hospitals,  Condominiums, Apartment Buildings, and Add-on Rooms & Sunrooms.

Business owners and homeowners face increasing challenges with energy costs to save energy and money in Maryland.  PTAC Energy Saver offers an Adaptive Climate Controller (ACC). It is a proven HVAC energy saving device that quickly installs on PTAC units. There are many companies that claim to produce energy savings, but the ACC device is multi-panted and proven over many years. Plus, it has extensive validation tests by organizations such as:

  • ConEdison, Manhattan Plaza New York City
  • Environmental Test Laboratory, Ohio
  • EME Consulting Engineers (Third Party), Sponsored by NYSERDA, New York
  • State University of New York, Oneonta, NY
  • Tim Garrison (Third Party Testing)
  • McQuay Cooling Tests
  • Purdue University Tests (Phoenix)
  • ConEdison Tests by ERS

Typically, when an HVAC system turns off, shortly after, the blower fan motor turns off. The ACC reprograms the blower fan not to shut off but to throttle back the rpm airflow to an exceptionally low speed, quiescent level airflow or “idle speed”. This allows for a gentle but continuous air movement into the building that helps keep equilibrium of climate conditions in the occupied space and saved energy.

Department of General Services Announces Maryland Continues to “Lead by Example” by Achieving a 12.5% Reduction in Energy Use in State Buildings

BALTIMORE, MD—Maryland Department of General Services (DGS) today announced the Office of Energy and Sustainability’s (OES) energy auditing program concluded its second year of audits and with the assistance of the energy audits, the energy use of state government buildings has decreased by 12.5%  and the state has saved  over $36.6 million in utility costs since 2018.

In addition to buildings owned and operated by DGS, the audit program reviewed more than 4 million square feet of state-owned buildings in the portfolios of the Maryland School for the Deaf, Maryland Transit Administration, Maryland Department of Military, Maryland Department of Energy, and the Maryland Department of Health.

“Reducing energy in the state government produces positive, environmental, fiscal and health benefits for all Marylanders” said DGS Secretary Ellington E. Churchill, Jr. “By upgrading and retrofitting our state office buildings with energy efficient lighting, HVAC controls, refrigeration, and other high impact measures the state will be able to achieve cost savings within a relatively short time frame.”
