What HVAC Systems Are Best for Coastal Areas like St. Augustine? 

Whether you’re replacing outdated equipment or upgrading to a ductless system, it’s important to choose an HVAC system specifically designed for our coastal climate. The salty air and high humidity in coastal regions can lead to accelerated wear and tear, making it crucial to invest in corrosion-resistant materials like aluminum or steel.

Heat pumps are a popular and energy-efficient solution for our subtropical climate. Installing a whole-house dehumidifier can also help you maintain comfortable temperatures in your home or business. From ductless mini-splits to anti-corrosion coatings, our experts can help you select and install an HVAC system built to last!
