AC Installation
Frequently Asked Questions
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.
How much does AC installation cost?
The cost of AC installation depends on several factors, including the size of your home, system type (central vs. ductless), energy efficiency rating, and whether ductwork needs upgrades or replacement. On average, central AC installation can range from a few thousand dollars to over ten thousand for high-efficiency models or complex projects. At Mainstream, we provide upfront, itemized estimates so you know exactly what to expect. We also offer financing options to help you get the comfort you need without stretching your budget. Our team works with you to choose the best system for your home, needs, and long-term savings.
How do you install Freon in an AC unit?
Adding refrigerant (commonly referred to as “Freon”) to an AC unit is a technical task that should only be performed by a licensed HVAC professional. Refrigerant levels must be carefully measured and added using specialized tools to ensure proper pressure and system balance. Overcharging or undercharging refrigerant can cause significant damage to your system and lead to costly repairs—or worse, system failure. If you suspect a refrigerant issue, Mainstream’s certified technicians can inspect your system, check for leaks, and safely recharge it to manufacturer specifications. We ensure your system runs efficiently while staying compliant with environmental regulations.
How do you install a ductless air conditioner?
Ductless air conditioner installation requires expert planning and precise setup. First, an indoor air handler is mounted on a wall inside the room, while a condenser unit is installed outside. The two units are connected by refrigerant and electrical lines that run through a small opening in the wall. Once connected, the system is charged, tested, and calibrated to ensure optimal comfort. Ductless systems are ideal for home additions, converted garages, or older homes without central ductwork. At Mainstream, we install ductless AC systems with minimal disruption and maximum efficiency—tailored to fit your space and your needs.
