HVAC Myth of the Week

Myth: Bigger equipment cools better.

Truth: Oversized equipment often short cycles, leaves humidity behind, wastes energy, and creates uncomfortable temperature swings.

The best HVAC system isn’t the biggest one…

It’s the right one.

That’s why every project should start with a Manual J load calculation.

🌧️ Monday in Florida...
