Once the installer put the air conditioner on we could feel the difference right away. The air smelled clean and the house cooled down within 5 minutes from the time he turned it on. The Trane air conditioner unit is very nice. Overall, A-1 Guaranteed did a GREAT JOB!! The installers were here on time. They came in and assessed the house for the job they were going to do. They came in and did the job in a timely manner and didn’t make a mess, they cleaned up after themselves and went over how to use the system.
