Replacing a 12-year-old Carrier rooftop unit with a Daikin 7.5-ton

On September 16 we replaced a 7.5-ton rooftop unit on a commercial building. The old unit was a Carrier 7.5-ton that had been running for more than 12 years.

We put in a new 3-phase Daikin 7.5-ton. It's the same size as the unit it replaced, so the building keeps the same cooling capacity it had before.

A unit that size doesn't go up a ladder. We used a crane to set the new unit on the roof.

Once it was in place, we started it up and checked it before we left the roof.

If your building's rooftop unit is getting old, or you're calling someone out to it every summer, call (832) 589-0813. We'll come look at it and tell you honestly whether it's worth repairing or it's time to replace it.
