Why Is My HVAC System Making That Noise?

Your HVAC system is one of the most important systems throughout your entire building. It is responsible not only for the comfort of your employees and tenants, but can preserve indoor air quality in businesses that need it the most. In a commercial kitchen, medical facility, or industrial complex, indoor air quality is of the utmost importance for tenant health and long-term safety. 

 

When your HVAC system starts making strange noises, you should immediately contact your MaintenX team. Even a slight issue with its performance can cost you thousands in repairs if not addressed immediately. If you hear any of these noises coming from your ents or outdoor units, give us a call. 

 

Squealing 

A squeal or screeching noise could mean the fan belt needs replacing, or the motor needs lubrication. These repairs are fairly simple and inexpensive, but neglecting to do them can cause permanent damage to your HVAC’s mechanical parts. 

 

Clicking 

A clicking noise on the first cold day of winter may be a good noise – it means your furnace is working after being out of commission for several months. However, if that clicking noise continues (especially if you’re having issues with climate control), it could mean your ignition system is malfunctioning. Call your technician if the clicking noise continues for more than a day to ensure further complications don’t occur. 

 

Thumping

If you can hear a rhythmic slapping or thumping sound within your outdoor unit, there may be something stuck in the motor or fan blades. This can cause significant wear and tear over time, which can lessen your system’s performance ability and cause other repairs down the line. 

 

Rattling or banging 

This noise is another sign that something is loose or broken within the fan components of the system. This sound often signals more extensive repairs, so the sooner you call your HVAC technician, the better. 

 

In most circumstances, an unusual noise coming from your HVAC system should be inspected by an HVAC professional. Even if the repair is minor, it’s better to fix it now rather than wait for disaster.
