Noisy Forced A/C and Heating Systems

We all know how noisy forced air cooling/heating systems can be. These noises can come from the grilles, the ducts, and from the fan. Our perception of noise is affected by both the frequency and the level of the sound. Higher frequency sounds (the sounds generated by high discharge velocities at grilles) are more offensive than lower frequency sounds (the sounds generated by the fan). For grilles there is a Noise Criteria (NC) rating that mimics the human perception of sound. The NC for a particular grille increases as more air is forced through it. 

When an air conditioner/furnace and duct system is properly sized to meet the cooling/heating load, it is easier distributing the cool air without being noisy. When a duct system is being designed, the NC level and face velocity of every supply grille should be considered and held below NC-25 and 700 fpm for a quiet system.

  • Wherever possible reduce the cooling/heating load of the house. Overhangs above east and west windows are particularly effective in reducing cooling load
  • Perform Manual J for all installations and select equipment using Manual S.
  • Insure that the system installed never exceeds the capacity of the equipment suggested by Manual S.
  • Size duct systems based on Manual D, if in doubt size upwards.
  • Confirm proper airflow by test. The flow can be determined from the coil pressure drop when pressure/flow data is available from the coil manufacturer or can be determined with a duct test rig or flow hood.
  • Increase the duct insulation to R-8 (at least on long runs in the attic).
  • Confirm that the duct leakage is less than 3% of coil airflow for a new system and less than 6% of coil airflow for an existing system.

Air Conditioning Contractors of America (ACCA) has provided 5 informative manuals pertaining to residential HVAC systems. Of these ACCA manuals D, J, and S contain information that is directly relevant to HVAC system function, design and efficiency.

ACCA Manual D
Residential duct systems have a direct and significant effect on equipment size, equipment efficiency, equipment malfunctions, envelope infiltration, operating cost, utility demand loads, vent performance, exhaust system performance, indoor air quality, ambient noise, occupant comfort and owner satisfaction. Therefore, the duct system must be carefully designed and properly installed or the potential benefits that are associated with building an efficient structure and using high efficiency equipment will not materialize.

ACCA manual D presents the methods and procedures that should be used to design residential duct systems. The subject material includes information about system selection (constant volume or variable volume), system performance characteristics, duct materials, blower performance, airside devices and duct sizing procedures. ACCA manual D also includes information about duct system efficiency and the synergistic interactions between the duct system, the envelope, the HVAC equipment, the vents and the household appliances. Indoor air quality, noise control, testing and balancing also are discussed.

ACCA Manual J

ASSA Manual J is primarily a load calculation manual. The first six sections of ACCA manual J outline a simple, accurate procedure, which can be used to estimate the heat loss and heat gain for conventional residential structures. Residential heating and cooling systems must be selected and designed to provide comfort conditions in all occupied spaces regardless of season. Temperature, humidity, air movement and ventilation must be controlled by the system. In addition, the system must perform these functions at maximum efficiency in order to minimize energy consumption.
The load calculation is the basis for the system design. Loads must be analyzed if the furnace, condensing unit, fans, coils, ducts, and air terminals are to be sized correctly. Comfort, efficiency and reliability are closely related to correct sizing and selection of equipment.
A load calculation must be made for each room so that the room cooling and heating requirements can be determined. This information is needed for terminal selection, fan and duct sizing. A load calculation must be made for the entire structure in order to properly size the heating and cooling equipment.

ACCA Manual S

ACCA Manual S is a comprehensive guide for selecting and sizing residential heating and cooling equipment. ACCA Manual S documents the procedures that should be used to select and size residential cooling equipment, furnaces and heat pumps. These procedures emphasize the importance of using performance data that documents the sensible, latent or heating capacity for a wide variety of operating conditions. This manual also suggests sizing strategies for all types of cooling and heating equipment and it discusses the nuances of the presentation formats that are used by equipment manufactures.
All readers are encouraged to study sections 1 and 8 of ACCA Manual S. Section 1 is a prerequisite because it provides and considerations that affect equipment selection. Section 8 is useful because it explains why certification ratings should not be used for selecting equipment.

Good HVAC Practices for Residential and Commercial Buildings

Book Description
Publication Date: 2003
In this brand-new resource from ACCA for HVAC Contractors, get a "roadmap" that addresses many of the concerns your customers (and insurance carriers) have, including: humidity control deficiencies; moisture incursion; and contaminant emission and transport. This new book helps contractors enhance system performance and improve customer satisfaction, but it also may reduce liabilities by presenting a "standard for care" and framing a business opportunity that can help contractors increase their profits. It's a must-have for commercial and residential contractors. The Good HVAC Practices guide is a valuable resource to assist HVAC contractors and designers in identifying and incorporating recognized industry practices into their business operations. The guide applies to new construction as well as replacement/retrofit markets for both the residential and commercial air-conditioning sectors. By using Good Practices, HVAC professionals are better positioned to differentiate themselves in the eyes of their customers, reduce the risk of liability through fewer callbacks, provide for greater equipment reliability/performance, and improve long term customer satisfaction -- factors that can reasonably be expected to produce increased profitability. Additionally, companies who incorporate Good Practices into their business operations are more likely to be recognized for following good industry practices, which may help to secure/maintain corporate liability insurance for such things as mold litigation.

What Your Contractor Can't Tell You: The Essential Guide to Building and Renovating 

Book Description

Publication Date: January 1, 2008 
What Your Contractor Can't Tell You is a comprehensive guide to getting the best results while building or renovating a home. Most homeowners spend about 20% of their time on the plan and 80% of their time on a messy, traumatic, expensive construction phase. Pros spend 80% of their time on the plan and 20% on a smooth construction phase. But the homeowners can't know what goes into a solid plan unless someone tells them. This book is based on a simple premise...if homeowners knew even 10% of what the professionals in the construction field know; they could avoid 90% of the problems. Creating a dream home shouldn't be a nightmare. Hiring a contractor is an enormous investment and a high-risk endeavor involving decisions that will last forever. This book equips homeowners with the information and strategies needed to turn their vision into a home or a renovation that can be built on time and within budget. Chapters give detailed coverage of critical topics: design; selecting and supervising the architect and contractor; cost estimates; budget; plan specifications; contracts; dealing with town officials; and keeping track of everything along the way. For each stage of the project, there is detailed information on common pitfalls and how to avoid them, as well as insiders' tips which reveal what most contractors can't tell you.

Customer Review

This book is excellent for those new to building or renovating and need to know what to do and say and who to say and do it to. The author does an excellent job setting out the relationships, processes, chronologies, and thinking for dealing with other parties all the way from dreaming about doing a remodel/build to finishing it. This is exactly the book I was looking for -- not a technical manual about building, but a handy reference about my role as owner and how I can or should interact with the architect, lender, general contractor, etc. to get the home or addition I want.
