Under normal circumstances, there is a particular sound that you expect from your furnace or AC.
This should be something you are used to such that any slight variation from the typical sound will be easy to notice. Usually, there are a few sounds, including clicking sounds, that you may see when the thermostat gets to an optimal temperature and signals the furnace. It is also customary to hear a whooshing sound as air flows through the furnace. However, strange sounds that are not a result of normal thermostat functioning should be something you are keen on. While some blowers are generally louder than others, it is not common to have an extremely loud furnace, especially for residential purposes. HVAC business manufacturers consider some of these factors when coming up with heating solutions for homes. So what should one do when they realize that their furnace is too noisy? Well, the first step is to check for something that needs tightening. Sometimes a loose item in the furnace could be responsible for such noises. Rumbling noises whenever the furnace is turned on is also indicative of a significant issue. The best thing is to switch off the furnace and immediately contact an HVAC technician for professional assistance. More often than not, these professionals understand what could be happening. A few hours later, the furnace was fixed, and no strange sounds were coming out of it. The HVAC serviceman had tightened all the loose wirings and taken care of all other issues that could be triggering the weird sounds. The furnace was quieter and running smoothly afterward.
