How Long Do Commercial Dehumidifiers Last?
Argendon TeamIt is common for you to wonder, “How long do commercial dehumidifiers last?”.
3 - 5 years is commonly cited to be the average lifespan of different brands of commercial dehumidifiers. While largely true, this number is also heavily dependent on the amount of wear and tear your dehumidifier receives over the years.
So, in this article, we’ll discuss the answer to how long do commercial dehumidifiers last from multiple different angles, including some effective tips to prolong your dehumidifier’s lifespan.
What Do the Experts Say About Dehumidifiers' Lifespans?
Stating one particular number and saying that your dehumidifier will last for this many years is the wrong approach to answer our primary question. This is because there are so many different types of dehumidifiers available in the market and each one of them has its own capacities, features, and usage purposes. Hence, the lifespan of these machines also varies by their types.
For example, crawl space dehumidifiers are made to work in more challenging situations, so they can generally work up to 5 years or more. Similarly, reliable manufacturers make commercial-grade dehumidifiers with sturdy and durable parts to ensure they can work for a long period of time with maximum efficiency.
Moreover, the working conditions of the commercial space also deeply impact its lifespan and efficiency. For example, if a commercial dehumidifier has to work in extremely unfavorable environmental conditions, it is likely to last less than a dehumidifier working in balanced conditions.
The key thing is that if you start facing any technical issues with your commercial dehumidifier, you should get it checked by the experts immediately to keep the unit running smoothly.

Key Factors Affecting a Dehumidifier’s Lifespan
The following are the key factors that affect a dehumidifier’s lifespan:
1. Usage Intensity
Commercial dehumidifiers have to run constantly in damp conditions, which puts extra stress on their electrical and mechanical components. Working in too harsh conditions can also lead to issues like the coils freezing. So, running your dehumidifiers constantly instead of occasional use can shorten their lifespan.
Though it is important to note that most of the modern commercial dehumidifiers are manufactured with the expectation that a business will have to run 24/7, so with regular maintenance, they can also last a long time.
2. Maintenance Frequency
Mold, dust, and other such air impurities will definitely clog your commercial dehumidifier’s filters and coils over time. Such a blockage will cause the machinery to work harder and get less efficient. Moreover, constant strain on the dehumidifier can also result in premature failure if not addressed properly.
This is why regular cleaning and maintenance are vital to keep your dehumidifier running efficiently with less energy consumption and more moisture removal.
3. Environmental Conditions
You need to explore different types and models of commercial dehumidifiers to ensure you are choosing the unit that suits your requirements. In areas where humidity is consistently high, you’ll need a heavy-duty commercial dehumidifier to extract moisture from the air without strenuous operations.
So, always consult the manufacturer’s guidelines to ensure the unit you are buying is actually capable of removing the expected amount of moisture.
4. Overall Installation
There are many factors involved in the installation of a dehumidifier itself. You can also integrate it into your existing HVAC system. Proper integration helps in maintaining a healthy indoor air throughout your commercial space. But on the flip side, wrong installation or low-quality integration can disrupt your entire system and potentially reduce the lifespan of the dehumidifier.
5. Brand Quality
Just like in any other product, your brand choice also affects the efficiency and durability of your commercial dehumidifier. Argendon is one brand that takes immense pride in offering high-performance, reliable, and energy-efficient dehumidifiers that last a long period of time because they are built with modern technology and quality components.
You should always choose a dehumidifier brand that is known for its quality products and offers an excellent warranty.

Common Signs Your Dehumidifiers Need Replacement
Identifying whether a dehumidifier needs repairing or replacement can be difficult, especially if you are not very familiar with these machines. If you are facing any difficulty with commercial dehumidifiers, your first step should be consulting professional technicians to inspect them and perform any required maintenance.
However, if the issue persists and you encounter the following signs, it means your dehumidifier is near its end:
- Lack of effective removal of maintenance despite maintenance
- Strange noises and constant vibrations while the machine is running
- Constant leaks due to mechanical issues
- You have to continuously restart the dehumidifier
- Strange damp smells
How Can I Maintain Commercial Dehumidifiers to Extend Their Lifespan?
The average 5-year lifespan is not something that is set in stone. In fact, you can definitely extend it by a few years by following these tips:
1. Regular Cleaning

Clean your commercial dehumidifier regularly to ensure there is no dirt, dust, or debris that can impact its performance. You can get guidance from the manufacturer or the user manual to properly clean the unit yourself.
Moreover, if your dehumidifier does not have an automatic pump and drainage system, you must be careful to prevent overflowing and avoid water damage. Generally, it is recommended that you buy a commercial dehumidifier with a pump for proper drainage.
2. Proper Installation
Always rely on the professionals for the proper installation and placement of the dehumidifier. Generally, it should be located in a well-ventilated area with a significant distance from walls and furniture to ensure sufficient airflow. You should avoid placing the unit in a corner or against a wall, as it can restrict air circulation and result in poor performance.
3. Avoid Overworking
If your space has a high amount of moisture, then you need a heavy-duty commercial dehumidifier, such as the Argendon XStorm Pro, that can remove 180 pints at saturation. But don’t make the mistake of overloading your dehumidifier by making it remove excessive moisture beyond its capacity. Hence, choosing the dehumidifier model as per the size and humidity levels of your area is vital.
4. Control Humidity Levels
Modern commercial dehumidifiers are also equipped with smart sensors to help you set the humidity levels at an optimum range. This helps you avoid excessive operation and minimize wear and tear over time.
5. Protection Against Power Surges
You can install power surge protectors to safeguard your dehumidifier against unexpected power surges and voltage fluctuations. This is important to protect the electrical components, especially if your business is in an area that experiences power fluctuations.
6. Follow the Manufacturer’s Guidelines
Argendon commercial dehumidifiers come with detailed user manuals and guidelines from the manufacturers. You should comply with the manufacturer’s instructions and recommendations regarding the usage and maintenance. If you have any doubts, consult the technicians to ensure optimum performance and extend the overall lifespan.
Conclusion
Commercial dehumidifiers are meant to last long, with the average lifespan around 3 to 5 years. But many users can keep these machines running longer through regular cleaning and maintenance.
The key thing to remember is to always install a commercial dehumidifier that suits your space’s size and humidity levels to avoid putting too much pressure on the unit and keep it running for a long time.
