As members work to repair systems damaged by Hurricane Sandy, the Air Conditioning Contractors of America is reminding them that split-system air conditioners and heat pumps must be properly matched.

Since many of the damaged HVAC systems were installed before the 13 seasonal energy-efficiency ratio took effect in 2006, contractors may need to replace the entire system to ensure it works properly.

ACCA officials noted that the group’s 2010 installation standards also cite the need for matched components.

“ACCA knows that the majority of professional contractors are out there selecting equipment properly and following the federal requirements for matching split-system air conditioners and heat pumps,” said Paul T. Stalknecht, the ACCA’s president and CEO. “However, any time a major disaster happens and there is a large influx of work, unprofessional contractors looking to make quick money come onto the scene. In addition, many insurance companies and their adjuster representatives may be unfamiliar with this system matching requirement when claims settlement offers are tendered. We want to remind HVAC contractors how important it is to do things right by following the quality installation specification and educating your customers about this need. When homeowners are already dealing with the difficulty of losing everything and the complexities of seeking insurance settlements, we want to make sure that replacing their heating and cooling system does not add to their stress.”
