Will you help me calculate the air conditioning unit I need regarding tonnage?

I have a friend who’s an HVAC mechanic and I can ask him but don’t you have one there you can ask? I would think in Florida, there’d be an HVAC place on every block.

Is there insulation in roof and walls? How much ?

How many windows and are they facing south ?

Are there ceiling fans – - how many ?

There is insulation for the walls and ceiling.

3 garage doors that are insulated also.

5 windows, 3 of which face south, but they will have window treatments to block the sun.

4 tons (41,000 BTU) should do it. If you are worried about the extra height, go a little bigger.

We have a similar sized building in North Carolina at a club that I’m a member. We have dances and socials with 100 to 180 people.

No windows, standard insulation in walls and ceiling. We have three industrial sized ceiling fans.

Three two ton HVAC units with “Gas Pack” for heating, each with a separate thermostat. Smaller units are better at removing humidity, large units will cool in a hurry but don’t remove moisture and can “short cycle” which wears out motors . . .

Ceiling fans help a lot in rooms with high ceilings.
