HVAC units get louder as they age, larger capacity units will produce a louder sound & if you allowed your unemschemed uncle to install it imrespectfully, you may have lost sleep when the component begins to rattle at 2:00 a.m
A Scottish mathematician named John Napier discovered logarithms in the early 17th century & the world has never been the same since. The pH scale in chemistry is logarithmic as is the well-known Richter scale used to measure seismic hobby. The basis for any logarithmic scale is that an increase in 1 component means a tplot increase that is tenfold. For example, a Richter 7 earthquake is 10 times as strong as a Richter 6 & 100 times stronger than a Richter 5 quake. The measurement of sound in decibels (dB) is 1 more arena where logarithms are used. Total silence is 0 dB, a lady breathing is 10 dB, & a loud rock concert is about 120 dB. A quiet bookstore comes in at about 40 dB so it is no surprise that an outdoor AC compressor making a 60 dB sound will earn a stern look from the librarian. Many factors affect the sound that HVAC units make. A solidly built 1 will be quieter than a flimsy model. HVAC units get louder as they age, larger capacity units will produce a louder sound & if you allowed your unemschemed uncle to install it imrespectfully, you may have lost sleep when the component begins to rattle at 2:00 a.m. when even your teenagers are quiet. Manufacturers are aware that people want & need a quiet environment & have come up with innovations appreciate variable-speed blowers, sound dampening outdoor cabinets, quieter fans, & even discharge mufflers. If your uncle installed that HVAC condenser right outside your dining room window, you may want to call a qualified HVAC dealer to see if it can be moved to a location where the noise won’t keep you awake at night.
