Possible Causes Of The Sounds Coming From Your Residential HVAC System

Most homeowners are acutely familiar with the subtle noises that come from their HVAC system when it is in operation. Thus, the moment you start to notice weird rattling sounds coming from this system you may be concerned that there is something wrong with it.

The first thing that you should know is that it is never advisable for amateurs to tinker with their HVAC systems, as they could easily cause further damage to the system. Secondly, you should never put off seeking professional HVAC services, as the underlying cause of the noises could worsen over time. So what could be causing the weird sounds to come from your residential HVAC system?

Detritus has collected inside the exterior unit

HVAC systems typically comprise two major parts, the indoor and the outdoor units. These units are tasked with containing the various components that are vital for the functionality of this system. Outdoor units are tasked with preserving the compressor, condenser, and the fan of the HVAC system. When these parts are in operation, they tend to generate heat so there must be sufficient ventilation so that they do not overheat. With that said, outdoor units are designed with multiple openings so that air is constantly circulating in and out.

Although these slats are vital, they do pose the issue of allowing detritus to steadily collect inside the outdoor unit. If you do not engage in routine cleaning, organic debris such as leaves, twigs, and soil will accumulate inside the unit. Moreover, rocks and pebbles can also make their way inside. Therefore, when you turn on your system, you will hear loud rattling coming from the unit. As such, you need to hire an HVAC contractor to come and perform a thorough cleaning or the mechanical parts inside the unit are at risk for permanent damage.

The residential HVAC's motors have broken down

Your residential HVAC system is made up of a series of motors that are tasked with facilitating the movement of refrigerant in this system. These motors are constantly hard at work so if there is a minor malfunction in your HVAC system, it could jeopardize the functionality of one or more motors, leading to strange noises.

One of the most common reasons why motors fail is when a bearing in your unit's belt drive is defective, as this will impede the motor's function. Additional reasons why you could experience motor failure include diminished lubricant, challenges with the voltage, and so on. Take note, you should never investigate a broken-down motor on your own. Instead, you should have an HVAC contractor come and resolve this problem. Contact an HVAC contractor for more information.
