What is the step-by-step AC installation process homeowners should know?

Sierra Air Conditioning & Plumbing’s step-by-step AC installation process moves from evaluation and design to removal, installation, commissioning, and a homeowner walkthrough. Most projects begin with an in-home assessment, system sizing, and a written estimate with ducted or ductless options. We perform this process across the area and have hands-on experience serving Moapa Valley homes. Free estimates and second opinions are available; financing is offered upon approved credit.

On install day, you can expect:

• Protect work areas, recover refrigerant, and remove old equipment.
• Prepare ducts or mount mini-split heads; set pad and place condenser.
• Connect lines, electrical, and drain; pressure test, evacuate, and charge to spec.
• Verify airflow and temperature split, calibrate thermostat, show operation, and clean up.

Clear a path to the indoor unit and electrical panel before the crew arrives.
