How do you install an air conditioner?

Installing an air conditioner involves more than just placing a unit outside—it requires a full evaluation of your home’s cooling needs, electrical system, and ductwork (if applicable). A licensed AC installer begins by removing any old equipment, then carefully positions the new unit, connects refrigerant lines and electrical wiring, calibrates the thermostat, and tests for safe, efficient operation. At Mainstream Electric, Heating, Cooling, and Plumbing, our trained professionals follow manufacturer specifications to ensure your AC system is properly installed and built to last. We make the process seamless from start to finish, with honest recommendations and no surprises.
