HVAC Installation – What Is Important?
In general, air conditioner manufacturers produce high-quality products, most of them with quality assurance processes to ensure it. It is at the time of installing or upgrading the HVAC system that the issues will arise.
Home Discomfort by Humidity Level Too High
The most common issue with a new HVAC system not delivering efficient comfort began before it was ever installed. Studies have consistently shown that HVAC systems are oversized, rather than undersized. Oversized equipment will not provide proper humidity control, resulting in higher energy bills, owner comfort complaints and a shorter life span. While undersized equipment will not provide sufficient heat removal, resulting in warm rooms and owner comfort complaints.
To avoid this problem a properly conducted load calculation must be completed, following the Air Conditioning Contractors of America’s (ACCA) Manual J methodology. A cautionary note should be applied here – not all Manual J calculations are the same. This is primarily due to the lack of knowledge or experience of the individuals using the software, assuming the input values for thermal characteristics (Window U/SHGC-Values, Wall, Ceiling, Floor R-values).
A quality HVAC contractor will conduct a load calculation using computer software which utilizes the Manual J methodology.
Noises and Early Equipment Failure
Another common problem are improperly sized ducts. Duct and register size should also be based on the initial HVAC load calculation for proper operation. Undersized return air or supply ducts can impede efficiency and overwork your compressor.
High Electrical Bills, Cooling Air Not Distributed as Required
Improperly sealed ducts can be the cause. Duct work that has not been properly sealed will leak and lose valuable cooling or heating into the attic or other undesirable area which can cost you money and make the system work inefficiently.
AC Water Dripping
Another common issue that can arise from improper installation practices.
