Air conditioning units that exceed three tons or 36,000 BTU per hour require a permit. If anyone asks, I was able to talk to the Manhattan city manager of the New York City Buildings department. And yes, you need a permit. Apparently, most, but not all, air conditioners require a permit to use the equipment.
This particularly applies to any climate control system that has more than 800 CFM. Yes, you need a building permit to install, modify or replace any permanent heating or air conditioning system. The permit allows homeowners to install and operate various machines, such as boilers, heating systems, elevators, fire alarms, sprinklers, air conditioners and any other equipment mounted on the roof or roof. We'll discuss your air conditioning needs with you thoroughly, covering factors such as the size and age of your home.
When it's time to replace your air conditioner unit with a new, energy-efficient system, permits are a crucial step. A permit to operate air conditioning and ventilation equipment requires an “equipment use permit” before the machinery is operated. Once plans for installing an air conditioning system have been approved, the contractor obtains a permit and the equipment is installed. Both the Construction Department and the Fire Department inspect air conditioning and ventilation systems.
In addition, all air conditioning systems must pass a thorough inspection and testing by a certified technician, architect, or engineer in accordance with established procedures. Some types of air conditioning and ventilation systems require a special installation permit known as an equipment use permit (EUP). All air conditioning units are assigned the SEER rating (which stands for seasonal energy efficiency index), which ensures that the system is safe and environmentally friendly. This is an example of why choosing an established professional air conditioning service company like Walton is the right path.
