What Causes Facet Syndrome? Facet syndrome is generally the result of the natural aging process. However, the initial cause of arthritis, or facet syndrome, may also be an injury or overuse of the joints in youth. Another possible cause of facet disease is spondylolisthesis, which is when one vertebra â usually in the lumbar spine â slips forward over the lower vertebrae. When the facet joints become inflamed due to injury or age, the result is stiffness and pain.
An energy recovery ventilator (ERV) is a type of mechanical equipment that features a heat exchanger combined with a ventilation system for providing controlled ventilation into a building.
These products are now called heat recovery ventilators or HRVs. Generally, in the Austin climate, there is not a significant energy dollar savings from using this type of equipment since they are quite costly (approximately $1,000 plus installation). The winters are too mild and short and the units are not as effective in the cooling season.
