Frequent complaints with HVAC systems are that there are large temperature variations between rooms as well as between floors in houses. Heating and cooling Grosse Ile Michigan contractors usually use the term “correcting temperature differences” between different areas as trying to balance the system. A HVAC installation that’s correctly measured and properly installed will require just a minor adjustment to ensure a proper temperature balance. In actual use, HVAC system sizing and mistakes in installation are not uncommon and can result in a difficult balance.
There are various standard for performance in cooling and heating in HVAC equipment. There is the International Residential Code (IRC) heating performance standard stipulates that the system be maintained at an indoor temperature that is at least the smallest of 68Es F. This is because the IRC does not have a performance standard for cooling. Its National Association of Home Builders (NAHB) heating performance standard is 70Es F. and the cooling standard is 78Es F. or 15Es F. Below an outdoor temperature that is 95Es F. The performance standard temperature is usually located near the center of the room, and approximately 5 feet higher than the flooring.
Balancing Is Influenced By A Variety Of Elements That Change On The Time Of Day And Time Of Year
The factors that influence the balance of the room are: position (south and west-facing rooms are often less able to be cooled) Size, quality, and position of doors and windows ceiling height and size of the room the size and position of the return and supply registers, thermostats’ location and position that the AC handler is located in relation to the space (the air handler is required to push air through ducts in an unconditioned area). Since a balance problem could be caused by multiple factors, resolving the problem may require several solutions. Here are some basic solutions to balance issues.
- Check that all return and supply registers are unobstructed and open.
- Check that the filters were cleaned or changed according to the manufacturer’s guidelines.
- Make sure that the ducts have been measured and fitted in accordance with the recommended guidelines.
- Verify that the insulation has been installed correctly and in the correct quantity.
- Install sun shades on west and south facing windows in areas with high temperatures.
- Deciduous trees are planted on the west and south edges (sun in winter and shading in the summer).
- Increase air circulation in rooms that have doors by providing an airflow path in the event that there is none.
If these easy solutions don’t yield satisfactory results, additional solutions might be needed. This could include changing the return or supply configuration of the ducts and adding zones independently controlled by their own thermostats. A construction defect can cause your family’s health as well as safety at risk and could cost you money. Everyone’s Building Code helps you avoid problems with construction, whether you work yourself or employ contractors.
