Every homeowners wants the installation of a new air conditioner to go smoothly. In order to get the most value from a new system, insist that your HVAC contractor uses both Manual J and Manual D for load calculations.
Here’s a look at what these important tools are and how they can benefit you and your wallet.
Manual J and Manual D connect you with the right equipment
Load calculation tools Manual J and Manual D were designed by HVAC experts to determine the most appropriate systems for each home based on its unique characteristics. Manual J enables your technician to determine how much heat and humidity must be removed from your home to keep you and your household cool and comfortable despite the extreme summer weather. Although some contractors may tell you that they’re experienced enough to go by “rules of thumb” instead of Air Conditioning Contractors of America standards, you should insist that he or she goes by the book.
During calculations, your HVAC professional should consider such factors as:
- Home size and orientation
- Number of windows
- Number of household occupants
- Heat-producing appliances and lighting
Manual D is used in the design and evaluation of a home’s ductwork system. If you’re building a new house or planning renovations, Manual D will help your HVAC contractor plan ductwork that will appropriately support your cooling equipment. Even if you’re not planning home alterations, it’s smart to have your ducts sized and evaluated for compatibility with certain air conditioning systems.
Proper A/C sizing pays you back
A/C efficiency and effectiveness can only be maximized when your equipment is properly sized. Systems that are too small will struggle to keep up with your demands. Oversized systems waste energy with frequent on/off cycles and are unable to properly dehumidify a space. Finding that just-right system will keep you comfortable while using less energy.
