Both summer and winter can be brutal in Wisconsin. An HVAC system failure during extreme weather is more than uncomfortable; it can be dangerous. With close attention and proper care, you can reduce the risk of your heater or air conditioner breaking down. Here is an overview of the most common symptoms to look for.

Strange Noises

Perhaps one of the most telltale signs of a struggling HVAC system is unusual noises. A functioning system operates relatively quietly. Unusual noises such as banging, clattering, or high-pitched whistling could indicate various issues. Banging or clattering noises may suggest loose or broken parts within the system. At the same time, high-pitched whistling or screaming could point toward pressure problems.

The specific cause of these noises can range from a minor issue like a loose screw to something major like compressor issues. Contacting a reputable HVAC company at the earliest sign of unusual noises is essential. These professionals can perform a comprehensive check and identify the source of the noise. Leaving these issues unattended can lead to more significant and potentially more costly problems in the future.

Water Leaks

Finding water around your HVAC unit can be alarming and is certainly a sign that something is wrong. The AC part of your HVAC system removes moisture from the air. Usually, this moisture is directed into a drain pan and down a drain line. However, leaks can occur if the condensate drain becomes clogged or if the condensate pump fails.

A refrigerant leak can also cause excess moisture. Not only can this lead to water damage on your property, but it can also cause the HVAC system to underperform or even fail completely. If you notice water pooling around your HVAC system, don’t ignore it. Promptly reach out to a professional HVAC company who can find the leak and fix it to prevent further damage.

Unusual Smells

An unusual smell is another signal that something may be off with your HVAC system. If your HVAC system emits a foul odor, it may indicate one of several problems. A musty smell could suggest mold or mildew buildup in your ducts, while a burning smell could hint at an electrical issue.

It’s also worth mentioning that the smell of rotten eggs could indicate a natural gas leak, which is a serious issue and requires immediate attention. If you encounter any of these smells, you must contact an HVAC company immediately. They can conduct a thorough inspection, pinpoint the source of the smell, and take care of the issue before it escalates into a more substantial problem.

Poor Airflow

If your HVAC system isn’t heating or cooling your home effectively, or if the airflow from your vents is weaker than usual, this could point to several issues. It could be that your air filters are clogged and need replacing, or your system’s fan isn’t working correctly. Alternatively, it could be a more complex issue with your ductwork.

Regardless of the cause, poor airflow is not something to overlook, as it results in a less comfortable environment and higher energy bills. HVAC companies specialize in these types of problems and can diagnose and repair the issue, restoring your system to full functionality.

Unexpected Increase in Energy Bills

While it’s normal for energy bills to fluctuate with the seasons, a sudden and unexpected rise in your bills could indicate a problem with your HVAC system. If your HVAC system is underperforming due to a mechanical issue, it will need to work harder to maintain the desired temperature, which results in increased energy usage.

It’s not always easy to know the cause of a sudden increase in energy bills. It might stem from several factors, like a refrigerant leak, a malfunctioning thermostat, or an aging system. Contacting a professional HVAC service provider is the best way to diagnose the issue. Their expertise will help identify the problem and suggest the most effective solution.

Inconsistent Temperatures

Your HVAC system is designed to keep your home comfortable by maintaining consistent temperatures. If you notice drastic temperature variations from room to room, it could signal an issue with your HVAC system. This could be due to an inefficient system, poor insulation, or issues with the ductwork.

The problem may seem minimal initially. However, it can often lead to higher energy costs and discomfort in the long run. Contacting a professional HVAC company to inspect and diagnose the issue can help to ensure your system performs optimally, providing consistent comfort throughout your home.

Thermostat Issues

Do you notice your HVAC system isn’t responding correctly to thermostat settings or is cycling on and off frequently? This could indicate a thermostat issue. The thermostat is the command center of your HVAC system, and its malfunctioning can affect the overall system performance.

It could be a simple problem like a need for recalibration or a complex one like a wiring issue or an outdated thermostat. As troubleshooting thermostat issues can be tricky and often involve electrical components, it is recommended to contact an HVAC professional to diagnose and resolve the problem.

Frequent Cycling

An HVAC system that constantly turns on and off, also known as short cycling, is a common symptom of an underlying issue. This could be due to an oversized HVAC system that heats or cools your home too quickly, leading to frequent starts and stops.

Frequent cycling not only wears your system down faster but also leads to increased energy usage and costs. A professional HVAC technician can assess the system, identify the cause of the problem, and suggest the necessary repairs or modifications.

Long Run Times

If your HVAC system seems to run longer than usual to maintain your set temperature, it could be a sign of a problem. Long run times can indicate a variety of issues, including low refrigerant, a dirty evaporator coil, or an aging system that’s losing its efficiency.

Running your HVAC system for extended periods places additional strain on its components. This reduces the lifespan of your system and increases your energy bills. It’s critical to consult a professional HVAC service provider who can assess the situation and offer a suitable solution.

Physical Damage

Physical damage to your HVAC system is an obvious but often overlooked sign of a problem. This could include visible signs of wear and tear, such as corrosion, frayed wires, or damaged fins on the exterior unit. Your HVAC system can also experience damage due to a storm.

Physical damage not only affects the appearance of your system but can also impair its functionality. If you notice any physical damage to your HVAC system, it’s best to contact a professional HVAC service company. These professionals can evaluate the extent of the damage and recommend repairs or replacement components.
