Each year, many people throughout the United States experience severe storms. Unfortunately, these storms can sometimes cause massive amounts of damage to HVAC units. Since they’re typically found outside of your home, these units are prone to lightning strikes, flooding, and other types of storm-related damage.

If a storm system recently made its way through your vicinity, it’s good to learn how these events can damage HVAC units. Here are six signs that a recent storm damaged your AC system.

1. Losing Its Ability to Cool Your Home

When you turn on your air conditioner, it’s understandable to expect cool air to begin flowing throughout your home. Unfortunately, this doesn’t always happen after an HVAC system gets damaged in a storm.

When a storm damages your AC system, it can negatively affect this unit’s refrigerant supply. If this is happening, it’s wise to have an AC repair professional take a closer look at what you’re dealing with. Letting the refrigerant in your HVAC unit run out can cause more severe problems to happen in the future.

2. You’re Experiencing Breaker-Related Issues

You might also notice that your HVAC system isn’t turning on. To potentially resolve this problem, you might head to your home’s circuit box. When a storm damages an HVAC system, it can stop this unit from generating and using electricity properly.

If the breaker connected to your home’s HVAC system keeps resetting after you flip it, you might be the victim of a storm-related power surge. Considering the dangers of working with electricity, it’s better to have a professional inspect your home’s electrical system.

3. A Power Surge Recently Happened

In most cases, storms cause lightning to strike. If lightning hits any power lines, it can cause the electricity inside your home to shut off. Sometimes, power outages can last for days or weeks. In other cases, they only last for a few seconds.

While they might not seem as harmful as extended power outages, power surges can still cause a lot of damage. These events can fry compressors, wires, and fuses in a matter of moments. Even if you don’t notice any signs of HVAC problems happening now, power surges can cause issues to happen in the future. Because of that, it’s a good idea to have a professional inspect your AC unit after a power surge hits your home.

4. Your HVAC System Makes Strange Noises

After a storm moves through your vicinity, you might start noticing that your HVAC system begins making odd noises. In many cases, storms cause outdoor wind speeds to increase rapidly. Unfortunately, these winds can send debris like rocks and branches hurtling into your HVAC system.

As debris makes its way throughout your HVAC system, besides making strange noises, these items can damage your unit’s fan, compressor, and other integral parts or components. Should you hear your AC unit screeching while in operation, shut it down right away. This screeching noise is often a sign that there’s a dangerous pressure imbalance taking place inside of your unit.

5. A Flooded AC Unit

Most storms bring a lot of rain with them. As this happens, it can be extremely harmful to areas that are prone to flooding. If you live in one of these areas, you might have to deal with a flooded AC unit.

Chances are, this situation means that parts of your AC unit were underwater for extended periods. If this is the case, it can likely cause extensive damage to the electrical components of your HVAC unit.

6. You Notice a Strange Burning Smell

After a storm strikes, many people like to survey the outside of their respective properties for any signs of damage. While you’re doing this, you might notice a strange smell coming from your AC unit.

More often than not, this strange smell is the result of your AC unit experiencing a range of electrical problems. Considering the danger of having electricity come into contact with water, it’s important to shut off your HVAC unit right away. Next, contact an HVAC repair company to have a professional inspect your unit.
