Obtaining a building permit is mandatory for all construction projects in Florida, and the Florida Building Code, mechanical, requires it before installing, replacing or removing air conditioning or mini-split systems. You may think that a mini-split is so small that it doesn't need a permit, but local construction jurisdictions will require one. This is for public safety, as there are scammers who take advantage of homeowners. Permitting agencies require contractors to have licenses, and licenses require continuing education.
The Department of Energy states that, in order to install mini-divided heat pumps or air conditioners, the homeowner must ensure that they have permission to do it. The fundamental principles of these codes share many similarities and ensure the safety, efficiency and resilience of facilities. There are many studies that show that having your HVAC (heating, ventilation or air conditioning) system installed properly will save you energy on your energy bills. It's important to check the licensing requirements of the jurisdiction in which you plan to work, such as installing the split unit or air conditioner.
Contact your local code compliance office to ensure that you comply with the codes before starting an installation. Without a permit, you can't guarantee that the air conditioning will be done properly to heat or cool your home, and it could end up costing you more in the long run if you decide not to meet the requirements. Companies like Air Care are dedicated to their customers and have office managers who plan and coordinate technicians' schedules, as well as owners who personally oversee their work. If your mini-split is to build a new accessory housing unit (ADU), you may need additional permits, such as a location permit if you are in a landslide zone.
However, permits are required for window units that require mounting brackets outside or that modify the window frame or frame. Regulatory authorities also impose the condition of a few hours of theoretical classes and field work before obtaining the license. It's easy to install an outdoor unit with the indoor unit just across the wall and think that you're saving copper with a 5-foot cooling line and conclude that it doesn't work properly because the set of lines is too short. To work in Florida, you'll need an HVAC (heating, ventilation and air conditioning) license from the Department of Business and Professional Regulation.
You'll also likely have to ask your contractor a lot of questions about the finer details related to your installation, which will slow you down even more. There are no state licensing requirements for HVAC (heating, ventilation and air conditioning) workers in New York.
