The answer to 'should I get evaporator coil or' is that it depends on your specific HVAC system and needs. An evaporator coil is a critical component of a central air conditioning system that absorbs heat from the air inside your home and transfers it outside. Compared to a standalone air conditioner, an evaporator coil is typically more energy-efficient and can provide more even cooling throughout your home.
Some key factors to consider when deciding between an evaporator coil or a standalone air conditioner include the size of your home, your cooling needs, the age and condition of your existing HVAC system, and your budget. Generally, an evaporator coil will be a more cost-effective and efficient option if you have a central air system, while a standalone unit may be better suited for smaller homes or rooms. It's always best to consult with a professional HVAC technician to determine the right solution for your specific situation.
