    Reliable Straight Cool Systems for Jacksonville and Northeast Florida

    Caudill Supply offers dependable Straight Cool HVAC Systems for homeowners, HVAC contractors, builders, and property managers throughout Jacksonville and Northeast Florida. Straight cool systems are one of the most common air conditioning solutions in Florida, providing efficient cooling during the region’s long, hot summers. When paired with an electric heat strip inside the air handler, these systems also provide dependable heating for the cooler months.

    Whether you’re replacing an aging air conditioner, installing a system in a new home, or upgrading existing equipment, our experienced team can help you select the right straight cool system for your application and budget.

    What Is a Straight Cool System?

    A straight cool system is designed primarily to cool your home by removing heat and humidity from the indoor air. Unlike a heat pump, which can reverse its operation to provide heating, a straight cool system works only as an air conditioner. During colder weather, heating is typically provided by electric heat strips installed in the indoor air handler.

    Because winters in Jacksonville are generally mild, straight cool systems remain a popular and cost-effective option for many homeowners throughout Northeast Florida.

    RunTru® by Trane Straight Cool Systems

    Our featured equipment line is RunTru® by Trane, offering dependable straight cool systems built with the quality and engineering homeowners expect from the Trane family of products. RunTru systems provide reliable performance, energy efficiency, and outstanding value, making them an excellent choice for residential replacements and new construction.

    Available options include complete matched systems with outdoor condensers, indoor air handlers, and compatible thermostats designed to work together for dependable comfort and efficient operation.

    Choosing the Right Straight Cool System

    Selecting the proper HVAC system involves more than choosing a brand. Proper sizing is critical to maintaining comfortable indoor temperatures, controlling humidity, and maximizing energy efficiency. An oversized system may cool too quickly without removing enough moisture, while an undersized system may struggle during Jacksonville’s hottest summer days.

    The knowledgeable team at Caudill Supply can help contractors and homeowners choose the right equipment based on the size of the home, efficiency goals, and budget. We also carry the accessories and installation materials needed to complete a successful HVAC installation.
