Here is a guide to some of the most common noises that will help you self-diagnose your system and help you decide when to call in the professionals.<\/p>\n<ul>\n<li><strong>Scraping noise<\/strong>: A scraping HVAC noise could mean that the fan is being obstructed by a foreign object. Should you hear this, you should immediately turn off the system. A broken fan blade can crush the fins eventually leading to leaking refrigerant. Part of your HVAC maintenance should include checking the fan for any breakages regularly.<\/li>\n<li><strong>Thumping noise<\/strong>: A thumping noise is another common HVAC noise that homeowners hear. Usually, this means that the motor or blower wheel is out of balance. This should be dealt with immediately to avoid bigger problems.<\/li>\n<li><strong>Rattling noise<\/strong>: This HVAC noise is especially common for the outdoor unit. It is usually as a result of debris getting caught in the coil. In this case, cut off the power and remove the debris. Ensure that there has been no damage to the condenser coils as well as the compressor and fan. Call a technician if there has been any damage. The rattling could also mean that there are some loose parts. For this, let a trained technician tighten everything back into place.<\/li>\n<li><strong>Hissing sound<\/strong>: If the HVAC noise you are hearing is a hissing sound, then this means that air is escaping from somewhere. A light hiss will indicate that the air is coming from the air vents and the air filter is not installed correctly. A loud hiss means that you probably have a duct leak and a whistle can indicate a refrigerant leak. In both cases, it is best to call in the professionals right away.<\/li>\n<li><strong>Pop\/bang<\/strong>: At times, the HVAC noise may sound like a pop or a bang. In this case, the ductwork is reacting from pressure from the fan. This could indicate a flimsy duct or a clogged air filter.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Let_Galmiche_Sons_Take_Care_of_That_HVAC_Noise\"><\/span>Let Galmiche &amp; Sons Take Care of That HVAC Noise<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>It is normal to have some sound while your unit is running.
