First Time Home Buyer, Meet Your HVAC System
NADCA Helps First-Time Home Buyers Better Understand the Components of Their HVAC Systems

MOUNT LAUREL, N.J.—January 2, 2014 – It’s easy to get wrapped up in the excitement of buying your first home, a place you can finally call your own; but with all of the joys (and added stress) of being a first-time homebuyer, comes some unfamiliar territory.

It’s important to understand the functionalities of the various systems within your home, in order to help you better determine when something is not working as it should be, especially as a new homeowner. NADCA, the HVAC Inspection, Maintenance and Restoration Association, is educating  first-time homeowners about the components that make up their air handling units and is providing tips for determining when a cleaning is necessary—and how to tell if a company is a reputable service provider.

“The HVAC system is the largest source of energy within a home, so it’s important to keep the units properly cleaned and maintained in order to avoid increased costs and energy usage,” said Bill Benito, ASCS, CVI, president of NADCA. “A dirty air conveyance system will restrict air flow at the coil and the blower, and also within the duct system. In many cases, a good cleaning of the cooling coil and the system components will increase air flow and make for a more efficient HVAC System. As a result, you’ll likely see significant savings on your energy bill.”

ACR, the NADCA Standard for assessing, cleaning and restoring an HVAC system, defines a complete and proper cleaning to include the inside of the air ducts from where the air enters the return duct, through the air handler (blowers, coil and heat exchange), to the exit, where the air is released to condition the home.

“When a complete and proper cleaning is performed, built up debris and contaminants will be removed, resulting in improved indoor air quality,” said Benito.

ACR, the NADCA Standard, was designed to reflect the most current industry information and best practices of HVAC inspection, cleaning and maintenance. The Standard sets an expectation for cleaning and restoring HVAC systems to a specific level of cleanliness and it provides guidance to professionals as they evaluate the cleanliness of system components.

Available for all industry professionals, ACR, the NADCA Standard, provides practical, reliable and industry-backed information for:

  • Assessing new and existing HVAC systems
  • Evaluating and verifying the cleanliness of HVAC system components
  • Preventing job related hazards
  • Guiding the cleaning and restoration o f HVAC systems to a specific level of cleanliness

Benito describes the duct work and the HVAC system of a house or building to function similarly to a set of lungs, “If there is substance or debris stuck in the air ducts, the system won’t be able to properly function and air flow will be restricted.”

In an effort to increase awareness about the HVAC system’s operating process, NADCA asks homeowners:

Did you know…

  • On average, forty pounds of dust is generated per year, in a 1,500 square foot home?
    The amount of dust that gathers in a home depends on several different components, including the HVAC system design, the location of the system (attic, basement, or crawlspace), along with the family habits—are there pets living in the home? Are there smokers? Children? All of these factors can contribute to the amount of dust and dirt that is generated within a home.

  • Approximately 4,200 dust mites can live within just one ounce of dust?
    Indoor air is actually not always cleaner than outdoor air. Contaminants inside of the home (like dirt, dust and animal dander) can be circulated during cleaning when ineffective or substandard cleaning devices are used. If the dust is not contained during routine vacuuming, it can be distributed around the living space, where it will eventually just resettle.

  • If you hire a professional to clean your HVAC system during the spring, the cost will typically be lower than any other time of the year?
    The reason for this is because although the spring months are the appropriate time for preparing for the cooling season, many homeowners wait until the summer to have their systems cleaned. As a result, there are very long waiting lists for scheduling appointments with NADCA-Certified technicians. In addition, many companies will provide discounts during the spring, to encourage homeowners to schedule their maintenance and cleaning before the units are needed for air conditioning during the summer.

NADCA urges homeowners to refer to the Residential Consumers checklist, available on the NADCA website. The checklist is designed to help homeowners understand NADCA’s recommendations regarding the process of HVAC cleaning.
