Some companies claim that these systems are easy to install as a DIY project. However, it’s important to consider the potential challenges and complexities involved. In this article from PD Plumbing, Heating & Cooling, we will explore the possibility of a DIY ductless mini split installation. Get valuable insights to help you make an informed decision.



The Difficulties of a DIY Mini Split Installation

Installing a DIY ductless mini split system is not recommended for first-time DIYers. It entails various complex tasks, including electrical work, which may require the assistance of a professional HVAC technician or electrician. How difficult this has been for homeowners has depended on the person’s skills and capabilities.

Those who have tried installing a DIY mini split have reported mixed experiences. Some encountered problems such as errors in refrigerant line installation, missing parts, and incorrect instruction manuals. Others reported difficulties in untwisting the lineset and matching electrical wires precisely.

Although you may have many handy skills, installing HVAC systems requires a higher level of expertise than other DIY home projects.

Consider the following questions before deciding to proceed with a DIY installation:

  • Do you have experience in electrical work?
  • Are you familiar with pouring a concrete pad?
  • Can you determine the appropriate system size, considering factors like climate, square footage, sun exposure, and insulation?

Reality vs. YouTube How-To DIY Ductless Videos

Head over to YouTube and you will find numerous videos of individuals successfully installing DIY HVAC systems. That may give homeowners encouragement to try it themselves. However, it’s important to recognize that most of these individuals are not average homeowners.

Many videos of DIY mini split installations have professionals doing the work. Or, if not professionals, will have the assistance of experienced HVAC technicians or electricians. And some videos and blogs are sponsored by specific brands, such as MRCOOL DIY.

YouTube can be great for a homeowner trying to learn a new skill or troubleshoot a problem. And it may even help some handle a complex task like a DIY ductless mini split installation. When looking for a video to follow, it’s crucial to choose instructional content that matches your skill level and capabilities.


Ductless Systems vs DIY Ductless Mini Splits

Not all ductless mini split systems are designed for DIY installation. Ads for DIY systems like MRCOOL DIY Ductless often portray effortless installations. But these units are different than the systems installed by professional HVAC companies.

DIY versions usually come with a pre-charged line set, reducing the complexity of dealing with refrigerant systems. However, typical ductless system installations require soldering work and specific industry tools. Systems not specifically sold as DIY versions may involve tasks beyond the capabilities of an amateur installer.


Considerations Before Installation

Before purchasing a DIY ductless mini split system, it’s crucial to determine the appropriate system size based on your space’s requirements. Factors such as climate, square footage, sun exposure, and insulation play a role in this determination.

Be aware that some components are not typically included in DIY kits. These items can include a dedicated 208/220 circuit, wiring to a junction box, and an AC shut-off switch. If you lack experience in electrical work, hiring an electrician and factoring in their costs is essential.

Also, it is important to note that DIY installations may not be covered by warranties unless performed by a licensed HVAC technician.


Cost Considerations

The cost of a DIY ductless mini split system varies depending on the brand, type, and specifications. On platforms like Amazon, prices typically range from $1,000 to $3,000. However, it’s important to factor in the time required for installation and the additional expenses for electrical components not included in the kit.

While it is possible a DIY installation may save money, it has the potential to actually cost you more. Consider the possibility that you may need to hire a professional HVAC technician if you’re unable to complete the installation successfully.

Avoid purchasing a DIY system with the intention of hiring professionals later. Most HVAC companies will not install a system a homeowner purchased themselves.


When a Ductless Mini Split Is Not the Right Choice

Ductless mini splits are excellent HVAC systems. But they may not always be the ideal solution for your heating and cooling needs. Consulting with an experienced HVAC company can help you explore alternative solutions that may be more cost-effective. Trusting professionals to assess your home’s comfort needs can lead to the most suitable solution.

However, ductless mini splits are excellent for a lot of spaces where a traditional HVAC unit may not work.

Some great place to install a ductless mini split include:

  • A kitchen that gets too hot
  • A sunroom
  • An added-on room that gets too hot or too cold
  • Replacing a window AC unit with a ductless air conditioner
  • A garage or workshop
