Are you still planning on placing a mini split compressor in your crawl space? Before you begin installing, here are a few things you need to know.
Key Considerations for Placing a Mini Split in a Crawl Space
Here are some things you need to consider when placing a mini split in a craw space.
The IRC on Heat Pumps:
The International Residential Code (IRC) is used in the United States and other parts of the world. Although the code contains information on heat pumps, it does not specifically prohibit their installation in crawl spaces.
The IRC talks about heat pumps in Sections M1403.1 and M1407.3. Section M1403.1 says that heat pumps must be labeled and regulated according to the correct method
Crawl Space Encapsulation:
Encapsulated areas don’t have the proper ventilation of air. In encapsulated spaces, air loss and supply are restricted. Heat pumps won’t work in encapsulated crawl spaces.
Accessibility and Serviceability:
Make sure your air compressor is easy to access so that it can be repaired when necessary. Put your compressor somewhere that gives it at least three feet of space on all sides.
Some parts of your machine are bigger than others and may need more room to be taken out, replaced, or fixed. Make sure your crawl space has enough room for that.
In a more complex crawl space, repairs, major component replacements, and even regular preventative maintenance will cost more.
Air Circulation and Ambient Temperature:
The temperature should be between 40 and 105 degrees Fahrenheit. If your air compressor is in a too-hot or cold room, it will have to work harder to keep up, causing the lubricants to wear out faster.
Warm air comes out of compressors. So, if your system is in a closed area, the area will get hotter and hotter, which will cause your compressor to shut down.
Your crawl space will need a proper system to let your exhaust air go outside. This makes the air coming into your unit much cooler.
Location of Power Distribution:
For every 100 feet between equipment and power source, wire size should be increased by one according to National Electric Code Guidelines. The price of powering your compressor gets higher as the distance to the power source rises. So locate your power distribution source .
Cleanliness:
If your crawl space is with a lot of dirt and dust in the air you need to do some ductwork. As a result, air will be brought inside, but the intake filter should be sufficient to clean the air coming in.
The compressor leaks oil, so you need A containment center to keep it from getting on your floors. You Know all the considerations to install the compressor in crawl space. In this section you will learn the installation process.
How To Install Mini Split Compressors In A Crawl Space?
To install a mini split compressor in a crawl space, you have to follow some steps. The steps are given below in detail.
Preparing Your Crawl Space For Installation:

Crawlspace Encapsulation:
It is the process of separating the area under your house from the living space or building envelope. It stops air from getting into your living space from the crawl space and makes your living space healthier.
Vapor Barrier:
A plastic vapor barrier on the floor of your crawl space might cut down on humidity from the wet ground below. It won’t keep the humid air from the outside out of a crawl space that has vents.
Waterproofing Or Mold Growth:
Mold can grow in your crawl space if there is standing water. You should start by fixing those problems first, seal the floor, vents, and walls completely.
Dehumidifying a Vented Crawl Space:
You can’t get rid of humidity in a room that’s open to the outside. If you try, the dehumidifier will run all the time, but the humidity in the crawlspace won’t go down at all.
Maintaining a Dry Crawl Space:
Put a dehumidifier in every crawl space that has been sealed off. The water from these devices, which are made to fit your crawlspace, goes straight outside. Also, put in humidity monitors so you can keep an eye on how well your dehumidification equipment is working.
Ensure Proper Drainage:
If your drainage system is insufficient, water can get into your crawlspace. Before encapsulation, you should talk to a structural engineer or drainage company if you see water standing under your home.
Backflow of Combustion Appliance:
Before encapsulating your crawl space, Always do a safety check. You can do this to see if there is carbon monoxide coming from your gas furnace or water heater. After going through these steps your crawl space will be ready to install the compressor.
