Designing inefficient ductwork can potentially compromise your home's comfort. Besides, it contributes significantly to your home's energy efficiency every year. Therefore, it's crucial to get help from an HVAC contractor when designing a ducting system for your home. When working with a heating and cooling contractor, consider this essential guideline for designing an energy-efficient ductwork system.
1. The Ductwork Design
There are various aspects to keep in mind when designing your ductwork system. Consider critical parameters like the sun's orientation, square footage and your home's floor design. Such aspects can significantly impact your chances of achieving a good balanced airflow. When designing your ductwork, consider a straightforward route your ducts should run from your air conditioning unit and your air supply registers. Furthermore, ensure proper insulation for ducts that run through unconditioned spaces to alleviate significant energy losses.
2. The Ductwork Sizing
Several factors affect your ductwork sizing, including HVAC equipment's size, heat gain and loss ratings, and distance to the furthest air supply register. Work with your HVAC contractor to design the most efficient and properly sized ductwork system when performing a home evaluation.
3. The Ductwork Location
When considering the location of your air ducts, it's crucial to ensure that every space in your home has a return grille. If you expect optimum air conditioning, consider installing return grilles in every section with air supply registers.
Another excellent option would be to utilise grille transfers for spaces that often have closed doors. Furthermore, ensure that your home's air supply registers are as closely located to your system's air handler as possible. That means installing them inside your home's interior walls.
4. The Ductwork Sealing
Any ducting system can potentially experience leakage down the line. That might occur much sooner than you expect when you have used substandard installation methods and materials. Work with a reputable HVAC contractor who can conduct a thorough ductwork inspection to identify any leakage problems. If there are any leaking sections, ensure proper sealing using mesh or mastic. Additionally, proper register and grille inspection are necessary to ensure they are appropriately secured.
5. Air Circulation
Finally, if you've been adhering to the above guidelines, you will achieve balanced air circulation in your home. Maintaining balanced air pressure is critical when designing an efficiently working ductwork system. However, unbalanced air pressure can cause infiltration of external air, which affects the overall indoor temperature, safety and energy efficiency.
