In the 1971s everything was still big, then big cars had yet to provide way to smaller “Econo” cars, however home sound systems were pressing with large console speakers with large woofers to pound out the beat. Big hair was the popular category with afros plus the post-hippie “Jesus look” for guys plus the “Farah Fawcett” look that was entirely popular with ladies. Hairstyles plus fashions usually fluctuate over time plus now there is even retro fashion for those wanting to capture the look of past eras; Those pressing speakers have been replaced by earbuds plus headsets plus even tiny speakers that can still pump out a pressing sound due to technical innovations. Housing is another section where smaller is becoming more popular than greater plus this means the size of Heating plus A/C systems must also adjust in size, but one solution in homes where space is a premium is to install small duct Heating plus A/C systems. These systems labor by using smaller HVAC duct plus bendy supply tubes that deliver cooled air at a higher air velocity (also called static pressure) than conventional forced air equipment. They offer other advantages aside from space saving because they are quieter, capable of removing more moisture from the air plus they really match any décor, but if any remodeling is needed, it should be minimal. Their use is not limited to small houses. Older homes not designed for Heating plus A/C plus even historical houses that must maintain their original look are really retrofitted with the small duct Heating plus A/C systems. The key to the small duct Heating plus A/C systems is Their use of small diameter bendy tubes that deliver air through small, almost invisible slots or circular vents; Wall vents can be really disguised with wallpaper while painting or staining will make them “disappear” into the floor.
