Explanation of garage as a multi-purpose space

Garages are no longer simply places to park your car and store items; they have become multi-purpose spaces used for household hobbies and activities such as woodworking, hobbyist projects, game rooms, laundry rooms, and more. To ensure you’re able to use your garage space as intended without any issues with humidity or moisture on a regular basis, having a dehumidifier installed is an excellent option.

A dehumidifier will help reduce the overall humidity levels in your garage space and keep it dry and clean. In this guide, we’ll discuss the process for buying and installing a dehumidifier for garages and how to use it most effectively.

Types of Garage Dehumidifier

After determining the size of dehumidifier needed, it’s important to understand the different types available so you can choose one that suits your needs. There are three primary types of dehumidifiers for garages – desiccant, compressor/refrigerant, and evaporative.

Desiccant Dehumidifiers: Desiccant dehumidifiers use a chemical material to absorb moisture from the air circulating through a drying chamber. This type of unit is best suited for cooler environments and low relative humidity such as in basements or garages. Personaly this type of unit is also an energy efficient option as well that doesn’t require additional heating or cooling beyond normal garage temperatures.

Compressor/Refrigerant Dehumidifiers: Compressor/Refrigerant dehumidification systems are well-suited for large areas with higher ambient temperatures and relative humidities. They use a refrigeration cycle to cool air circulating in the unit, causing moisture to condense onto cold surfaces and collect in a collecting tray or bucket at the bottom of the unit. This type of unit removes more water from the air than desiccants but can be more expensive due to their complex mechanisms and larger motors. They often come with built-in timers for programming them to turn off after desired humidity rate has been achieved, making them ideal for monitoring conditions in closed spaces like garages over extended period of times when no one is present.

Evaporative Dehumidifiers: Evaporative dehumdifiers provide increased moisture control through an evaporation process that combines both heat and humidity control into one operation.. The combination cools warm dry air as it passes over wetted spiral media which helps relieve uncomfortable indoor conditions as well as help maintain a desirable relative humidity level. These units tend to be more energy efficient than continuously running compressor/refrigeration units but offer less overall capacity than other types of units.


The key purpose of a dehumidifier is to reduce the amount of moisture in the air. Dehumidifiers are used to remove moisture from inside enclosed areas such as basements and attics or garages. They work by drawing in moist air, lowering the humidity level and then releasing gently heated, dry air back into the area.

Dehumidifiers come in many sizes and capacities depending on the size of your space and desired humidity level. There are generally two types of dehumidifiers: whole-house or portable. As their names suggest, whole-house dehumidifiers help keep a larger area dry and comfortable while portable ones are more convenient for smaller spaces like nurseries or bathrooms. Portable units may also have added features like auto shut off technology, built-in timers and LCD screens that make them easier to monitor and control throughout your home or garage.

Whole-house dehumidifiers help regulate both humidity levels and temperature in your entire home while portable units can be moved around depending to specific areas that need extra protection against high levels of humidity – like a cooler cabinets, closets, tool shed or workshop. For added convenience, many models also feature flat surfaces where you may conveniently place items such as clothes or accessories while they dry off after a good cleanse!

III. Choosing the Right Modifier for Your Garage

Whether you’re a car enthusiast, have an extensive tool collection, or like to spruce up your outdoor space with holiday decorations, having a dry and clean garage is a must for any homeowner. A dehumidifier can be used to help remove excess moisture from the air and keep mold and mildew from forming inside the garage. It’s important to choose the right type of dehumidifier for your specific needs, as well as the size of your garage.

When considering dehumidifiers for garages owners should examine their individual needs carefully. Dehumidifiers come in two main types: desiccation and refrigerant. Desiccant dehumidifiers work by drawing air over a material that collects moisture then using heat to expel it out of the system as water vapor while also cooling down incoming air simultaneously. This type of system is often preferred because they don’t produce condensation and they run quietly while providing consistent performance. Refrigerant dehumidifiers work by drawing warm air over an evaporator coil, cooling it down until it reaches its operating temperature at which point water begins to condense on its surface which is then collected in a tank or drained away via a hose that leads outside. Refrigerant systems typically have higher capacity than desiccant systems, but are much louder due to the running compressor so owners should consider this when making their choice.

Whichever type you choose make sure it’s rated for the size of your garage space— measuring both length and width— and has adjustable fan speeds so you can adjust it according to how much moisture removal power you require from one day to another depending on climate conditions outside or any activities taking place in the building such as painting or woodworking inside etc.

Factors to consider when choosing a Dehumidifier

When selecting a dehumidifier for your garage, there are several key factors to consider that will help you achieve the best results.

First, you need to assess the size of your garage. A smaller model may not be adequate for larger areas, while a larger model may be overkill and end up costing more to run than necessary. Consider measuring and calculating the square footage of your garage before making any decisions, as this will give you an idea of exactly what sized unit you need.

Second, consider the temperature in your garage and make sure that it falls within the functional range of the dehumidifier. Most models should not be used in temperatures lower than 40°F or higher than 95°F as such extreme temperatures can lead to breakdowns or damage to electrical components.

Third, look into features that are available on specific models such as built-in humidistats and adjustable humidification settings. These features provide control over internal moisture levels and provide flexibility when it comes to your humidity preferences within the space.

Finally, make sure that you check into energy efficiency ratings when selecting a dehumidifier for your garage as this will ensure that you’re getting the most bang for your buck when running it over time. Some newer models are Energy Star rated which means they meet even stricter standards when it comes to energy efficiency.

Humidity level in your area

When deciding what type of dehumidifier you need, it’s important to consider the humidity level in your area. High levels of humidity can lead to an uncomfortable environment, and can also damage items stored in your garage. Knowing your location’s average annual humidity level can help you determine the best type and size dehumidifier that will suit your needs.

Consider investing in a digital hygrometer, which is a device used for measuring the amount of moisture in the air. A digital hygrometer reads environmental humidity levels and indicates when they are too high or too low. Before selecting a dehumidifier for your garage, it’s important to take regular readings with such an instrument so you know what kind of exposure your items have been subjected to over time.

It’s also helpful to look into local regulations as some areas have laws restricting home humidification devices as part of their safety standards for combustible materials like gas or wood-burning furnaces. Knowing local humidification laws ahead of time can save you from needing to replace or modify equipment later on if those regulations change.

Cost considerations

Cost is certainly an important factor when choosing a dehumidifier for the garage. You’ll need to decide if you’d like to purchase a cheaper model with fewer features or pay more upfront for one with greater power and more features. Some of the features that can drive up the cost include auto shut-off, remote control, timer settings, low-noise design, washable filters, and high Energy Star ratings. It’s best to choose a model that fits your budget but is powerful enough to reduce humidity levels and maintain them for a long period of time.

Additionally, if you plan on purchasing extra air filters or other accessories in the future, it’s best to choose a model that has options available. When considering budget, also be sure to calculate maintenance and replacement costs such as filter cleaning/replacement supplies and repair expenses in case of malfunction. Additionally you should factor in the duration of use; dehumidifiers that require replacement after a shorter period of time may become more expensive over time than models with powerful motors and durability ratings. With good care and maintenance it is possible for many models to last longer than their manufacturer-suggested lifespan.

Maintenance requirements

It should be noted that proper maintenance is required to keep the dehumidifier working properly. Fortunately, since most of them use an internal reservoir the maintenance is easy. Clean out the reservoir and replace it once or twice a month. Check your filter as well as with all HVAC appliances and clean as needed depending on your home environment.

In addition, check over the air intake and exhaust vents to make sure they are not blocked by any other objects in the room. This can hinder airflow which can lead to more energy consumption from your dehumidifier. If you notice any malfunctions it may be time for a replacement but do not wait too long if you want to make sure it does its job effectively and continues to protect your belongings from extreme humidity levels in your garage space.

Installation and Maintenance of Garage Dehumidifier

Once you’ve chosen the right model for your garage space, installation and maintenance is the next step. Depending on the size of your garage, you may need to hire a professional for the installation process.

For smaller models that are not wall-mounted, setup and maintenance is straightforward. Generally, all you have to do is follow the manufacturer’s guidelines on where to place it in your space and make sure all connections are secure. Larger dehumidifiers that are wall-mounted or floor units may require professional assistance during setup as well as proper connections to an electrical outlet or to a drainage hose. For safety reasons, make sure that all connections are tight before using the unit.

To maintain it in good condition and keep it running at its maximum capacity, regular cleaning and upkeep should be performed often. Depending on how often it’s used, dust off components such as the evaporator coil or fan grille periodically with a damp cloth or brush attachment of your vacuum cleaner – paying extra attention to areas where dust accumulates quickly such as air filters and vents if provided. Additionally running self diagnostic tests if available helps detect any problems so you can have it serviced at an early stage before things get worse. Referring to the user manual for your specific model can help identify any potential problems as well as instructions for self diagnosis tests provides by certain manufactures if applicable.

The above steps should help maintain cleanliness in your garage while reducing humidity levels and keeping allergies under control. If however after trying these solutions indoor relative humidity does not seem improve consider consulting a HVAC professional or upgrading components of your system such a furnace filter , adding insulation , replacing windows/door seals etc based on Accessible inspection results.
