What is an HVAC Surge Protection and Why Do You Need It?

Your HVAC System is probably the most expensive home appliance you have, as it can often come with high costs in the long run, such as repair bills and replacement of parts. Investing in your HVAC System is no easy task, especially when maintaining its function and durability. In addition, to wear and tear, your HVAC system can also encounter problems when power surges occur, leading to severe damage to it.

Although we all know computers need a surge protector for both safety and cost-efficiency, your HVAC unit needs its own surge protector, as well. However, before doing so, you should understand how they work and the benefits of having one.

What Is An HVAC Surge Protection And Why Do You Need It?

What Exactly Is an HVAC Surge Protector?

HVAC surge protectors act as a buffer between your system and any power surges that can cause severe and irreversible damage to your system. The surge protector of an HVAC System is often found near or inside the system itself. An HVAC surge protector works by diverting any excess electricity away from your HVAC system.

However, instead of preventing power surges, the HVAC surge protector acts as a pass-through for excess electricity from the power source to your HVAC system. When a power surge occurs, the protector works to prevent your unit from getting too much electricity.

What causes power surges? A power surge occurs when there is a sudden moment of high amp fluctuation in electrical power. Such fluctuations can occur because of internal or external power surges. Faulty appliances or faulty wirings cause internal power surges. On the other hand, external power surges are often caused by lightning, downed power lines, and other electrical service issues. There are other causes in which a power surge occurs, and even a slight increase in voltage from a faulty circuit breaker box can harm your HVAC System.

Why Would You Need a Surge Protector?

An HVAC system is a serious and costly investment for your home. Because of this, you should get a surge protector for it to make your investment worthwhile. There are many benefits to having an HVAC surge protector. For instance, HVAC manufacturers say that an HVAC surge protector is necessary to prevent any irreversible damage done to your system, therefore prolonging the life of your HVAC system as a whole.

Surge protectors are also considered low-cost solutions, as they can act as a type of insurance for your unit. Keep in mind that a surge protector can be much cheaper than replacing an internal part of your unit.

Your insurance as a homeowner may not cover appliance repair or replacement, so it would be best to invest in a surge protector of your own. And even though there are home warranties that can cover your home appliances, such warranties probably do not cover damages from power surges. A good-quality HVAC surge protector will also significantly improve the safety of your home.

Are Power Surges Covered by an HVAC System's Warranties?

HVAC manufacturers tend to vary from one another, so you should choose a reputable manufacturer who will stand behind their product to have your warranty honored. Some HVAC manufacturers are willing to cover damage to specific components of your HVAC system, but the repair bills are not usually included. Depending on HVAC warranties, you should avoid any actions that can void your system’s warranty, including faulty installations, off-label repairs, power surges, and failure to keep up with maintenance.

It is also important to note that although HVAC companies provide a long-term warranty for your unit, power surge damage is not typically covered by such warranties. And even if it is covered, you will have the burden of proving that a power surge truly damaged your unit. The effects of power surges often take their time to show, so it would be difficult proving such cause. Ultimately, damages will solely be left up to you to shoulder.

Warranties of Surge Protectors

On the other hand, warranties of HVAC surge protectors are more convenient as some reputable manufacturers offer a specific type of warranty against any damage done to your equipment when their product malfunctions. It is always vital that you check the fine print to avoid any empty promises by manufacturers.

What Can Cause A Furnace To Stop Working?

Companies will often provide warranties of up to 5 years from the date of purchase or shipment for their HVAC surge protectors. It is also crucial that you should read and fully understand the specifications and limitations of a warranty provided by an HVAC manufacturer because they are all different from one another. One may be a better option for you to consider.
