The Johnson’s Polar Air 5-Step Installation Experience

Installing a central air conditioner or heat pump requires precise electrical, ductwork, and refrigeration calibration. We make the entire process smooth, clean, and worry-free:

1. Free In-Home Assessment & Manual J Load Calculation: We evaluate your home’s square footage, ceiling height, insulation values, and existing ductwork to calculate exact cooling tonnage requirements.

3. Meticulous NATE-Certified Installation: Our installation crew arrives on schedule, lays down protective drop cloths, wears shoe covers, and installs your equipment to strict manufacturer and local building codes.

4. Airflow Calibration & Quality Assurance Testing: Once installed, we test electrical draws, balance airflow across vents, pull deep vacuums on refrigerant lines, and calibrate your thermostat.

5. Impeccable Clean-Up & Customer Walkthrough: We haul away all old equipment and debris, clean our workspace thoroughly, and walk you through operating your new system with confidence.
