Expert AC Installation and Replacement Services

For a standard "change-out" (replacing an old unit with a new one using your existing ductwork), you can typically expect to be without cooling for 4 to 8 hours. Most of our installations begin in the morning and are completed by mid-to-late afternoon.

The process is divided into phases: first, we recover the old refrigerant and remove the existing equipment (1–2 hours); then, we set the new indoor and outdoor units and connect the lines (3–5 hours); and finally, we pull a vacuum on the system to remove moisture and perform a final test (1 hour). If your installation requires new ductwork, electrical upgrades, or structural modifications to your attic or closet, the process can extend into a second day, but we will always inform you of this timeline before work begins.

In many cases, you can keep your existing thermostat if it is a relatively modern. However, there are two specific situations where a new thermostat is required:

• Communication Requirements: Some high-efficiency, variable-speed systems use "communicating" technology. These units don't just turn on and off; they constantly "talk" to the thermostat to adjust fan speeds and cooling levels. These systems almost always require special thermostats often noted by the manufacturer.

• Voltage and Wiring: Older thermostats (especially manual dial versions) may not have the "C-wire" or the multi-stage programming needed for more modern models.

While you aren't always forced to upgrade, we generally recommend a new thermostat with a new system to ensure the internal sensors are as accurate as the new equipment they are controlling. A technician should always discuss if you need a new thermostat or if your old one will continue to work.

SEER2 stands for Seasonal Energy Efficiency Ratio 2. It is the industry-standard measurement for how much cooling an AC system provides per watt of electricity consumed. Think of it like a "miles per gallon" rating for your home, the higher the number, the more efficient the unit and the lower your monthly operating costs.

In places where air conditioners run nearly year-round, the rating you choose has a significant impact on your wallet. While the Department of Energy sets a baseline minimum efficiency for all new installations in the Southeast United States, many homeowners opt for systems that exceed these basic requirements. Higher-rated units often feature advanced technology, like variable-speed compressors, which are far more effective at removing heavy humidity than base-model systems. When selecting a new unit, the goal is to find the "sweet spot" where the long-term energy savings and improved comfort justify the initial investment.
