How can we repair a hole in an HVAC pipe?
Not a DIY repair. You are going to have to call an HVAC company out to fix it. The compressed air that you heard rushing out of it was actually refrigerant that makes the whole system work. This piece is going to have to be cut and a coupling soldered in place. It’s working right now because the tape might have slowed the leak, but soon the pressure will be too much for the duct tape and it will start leaking out again. This gas is harmful, both to you (if it’s coming in the house) as well as the environment. I would not use this unit if I were you. You need to call and get this repaired ASAP. If you run your system out, there’s a chance that the low pressure switch will not work and you could further damage your system.
