Why Choose Us?
Serving Florida's Emerald Coast Since 1984
Florida is tough on air conditioners, as we’re sure you know! Many of these AC systems run all summer long and even into winter. That hard work comes at a cost. And by its 10th birthday, the average AC is ready for retirement.
With proper maintenance and care, your AC can last well beyond 10 years. Still, you should be on the lookout for the telltale signs that a replacement is fast approaching.
