A Cased Coil in the 1.5 to 3-ton range is a fundamental part of a medium-sized residential HVAC system, specifically designed to be installed on top of a gas or electric furnace. When integrated correctly, this component allows the refrigerant to absorb heat from your indoor air with maximum efficiency. Professionals often look for these specific tonnage ranges when they are troubleshooting cooling performance in homes between 900 and 1,800 square feet. You can explore our high-quality selection of these components at AC Cased Coils 1.5-3 Ton to find a perfectly matched evaporator for your condenser. One of the primary benefits of a modern cased coil is its pre-insulated cabinet, which prevents condensation from forming on the outside of the unit. Installation should always be performed by ensuring the TXV (Thermal Expansion Valve) is properly calibrated to the outdoor unit’s capacity. At HVAC Supplies, we prioritize sourcing coils that feature all-aluminum construction to eliminate the risk of formicary corrosion. Choosing a durable cased coil ensures that your system can maintain high efficiency and reliable cooling for its entire service life. Ultimately, investing in a premium evaporator coil is one of the smartest ways to guarantee a healthy and efficient indoor climate.
