What we know about homes in Clay County
Half of Clay County's homes were built in 1995 or later
The typical Clay County home was built in 1995, and about 1 in 8 is a manufactured home. Systems from the 1990s and 2000s are at an age when it is worth comparing repair and replacement, and a 1990s system may still run on R-22 refrigerant, which hasn't been made since 2020.

Clay County HVAC questions
Do you serve all of Clay County?
We serve Keystone Heights, Middleburg and Green Cove Springs. Further north, toward Orange Park and Fleming Island? Give us a call and we will tell you straight away.
Is my older AC on R-22?
If it went in before 2010, it may be. The label on the outdoor unit says which refrigerant it uses. A checkup tells you, in writing, whether repairing it still makes sense.
Do you serve the lakes around Keystone Heights?
Yes, including Lake Geneva and Lake Brooklyn, and Lake Asbury near Middleburg.
