Business ProfileforAbsolute Airflow Inc

Purchased a new **** system with new vent/duct install on 4/1/2020 Over the course of 4 years, we've called them to come out and check two rooms because the air pressure from those vents were very low. Each time they came, they said everything is working great and there's no problems, so if its not strong enough close the vents in other rooms we aren't using.Called a separate company last week to come look, and they went into the attic, took pictures and showed me that the ducts were not properly measured, were bent and dented, which is why the airflow is being blocked and not providing strong flow.I called Absolute Airflow to inquire about my warranty and service to have them come out and repair/reinstall the vents. At first they asked me if its for the **** they installed and I said yes, and asked what's wrong so I informed them. They told me the warranty department would call me back. 15 minutes later the same person called me back stating she couldn't find any service agreement or warranty for my install. I luckily kept the documents and had to email them over or else it "wouldn't be covered". The following day warranty called me saying they'd have someone come out to "check what the other company said" implying that its false even though I've had them out here 3 times for this exact issue on Monday 9/9/******* is now past the appointment time, and they never notified me if they'd be late or when they'd show up. Calling them, they continue to deflect and say that someone will call me ******** this point, it seems they are not taking a reasonable effort to deliver on their 10 year labor warranty.
