When considering AC replacement, there are a few key things to expect. First, a professional assessment of your current system will be conducted to determine the appropriate size and type of unit needed for your space. Next, the old AC unit will be removed, and the new one installed, which may take a day or two depending on the complexity of the job. You can expect improved energy efficiency and lower utility bills with a new system. Additionally, your home will be more comfortable with consistent cooling throughout. Finally, make sure to ask your HVAC technician about warranties, maintenance plans, and any potential rebates or incentives for upgrading to a more energy-efficient model.
