The mini split AC has become a popular choice in cooling due to its energy efficiency, ease of installation and versatility. It can fit into small spaces and does not require ductwork.
If you are considering a mini split AC, you need to know your local regulations for permitting your project. This ensures that your installation meets building codes, environmental standards and safety standards. Obtaining the appropriate legal permissions is one of the first things to look into before unboxing your ductless AC.
Key Takeaways
- You do need prior approval to install HVAC equipment.
- Federal, state and local agencies oversee ductless AC installation.
- Applications are available at your city or county offices.
- Permitting helps ensure your project is safe and compliant.
- Project approval also helps you meet warranty requirements.
Who Governs Permits for Mini Split Installations?
The Department of Energy oversees safety and environmental practices for the HVAC industry. DOE makes recommendations to national organizations such as The American Society of Heating, Refrigerating, and Air-Conditioning Engineers to ensure compliance with federal energy efficiency standards.
Your state and local jurisdictions set the parameters for HVAC installations of all kinds, including mini split AC equipment. Each state has its own regulations for the heating and cooling industry. Each county and/or city within the state has its own specific building codes that apply to mini split AC systems.
When Do You Need a Permit for a Mini Split?
You need agency approval to install a mini split AC before you begin installation. If you have hired HVAC professionals to do the work, obtaining legal approval is their responsibility. They should have all your information necessary to fill in the application, provide supporting documents and attain approval for your project. Once you get the green light from the permitting agency, you can start your mini split installation.
Even if you have decided to install the equipment yourself as a homeowner, you still need legal approval. Otherwise, you could be liable for penalties for noncompliance with state and local mandates.
How to Obtain a Permit
Touch base with your local permitting office to find out how to get the ball rolling on your mini split install. A staff member should provide you with an application and answer your questions. Once your paperwork is complete, officials will decide whether to give you the go-ahead. Some of the questions to expect when you are filling out the application include:
- The property address
- The type of system you are putting in
- Your system configuration, whether it is a single unit or multiple zone AC
- Its BTU capacity
- A drawing of your installation plan
- The home’s existing electrical capacity
- Any special requirements
Your contractor must typically include credentials with the application, including professional licensing and insurance information. Many jurisdictions ask for diagrams of your existing electrical and plumbing systems. Once the application is complete, you need to submit it along with the fee. The amount of the fee varies, depending on your location.
Why Mini Split Applications Require Permits
Almost all HVAC installations require official approval, and the mini split AC is no exception. One reason for this is that any structural changes your contractor makes during installation must comply with local building codes. That is why your builders’ agency wants to see your installation plan. Inspectors also confirm code compliance once your project is complete.
Some systems, such as the hidden mini split, require opening up a wall of your home. All systems require a pass-through connecting indoor and outdoor components. Your contractor must know the location of your electrical wiring and plumbing when drilling into walls to avoid injuries. Your permitting office needs complete information, including diagrams, to check for and address potential safety issues.
Your home’s electrical panel must have the capacity to safely power your new equipment. You will need a certified electrician to make safe connections that comply with local building codes. That is why the permitting agency needs details about your home’s electrical setup when you apply for project approval.
In addition, a mini split uses refrigerant to cool warm air. If not correctly connected, the refrigerant supply line can leak. These leaks can cause poisoning or even explosions. EPA has standards for the handling of refrigerants to protect the environment. Safe handling also keeps your home healthy for your family. Local permitting agents look at your installation plans to help prevent toxic accidents. Later, inspectors will check too.
Safety and Legal Implications
Failure to seek the required permits before installing your mini split AC has safety and legal implications. For example, your new mini split could overload your electrical system, causing equipment failure or even a fire. A permitting office could have identified this issue in advance if you had submitted your electric wiring diagram with your application.
Also, if your mini split does not work as advertised after installation, the manufacturer will want to review your paperwork to see if your warranty claim is valid. Without the proper permits, professional installation and inspection, your warranty may be invalid. That leaves you paying out of pocket for damage and repairs.
