Installation Planning
Installation Steps
- Position the indoor unit according to the layout plan.
- Secure the unit to the mounting bracket or wall.
- Ensure that all electrical connections comply with local codes.
- Double-check alignment and levelness of the unit.
- Measure and cut ductwork to fit the installation area.
- Connect ducts securely to the indoor unit and vents.
- Use appropriate sealant or tape to seal all joints and seams.
- Inspect for any gaps or leaks after installation.
- Attach the refrigerant lines to the indoor unit and outdoor unit.
- Ensure connections are tight and secure.
- Use a leak detection solution to check for leaks.
- Repair any leaks found before proceeding.
- Select a stable and level surface for the outdoor unit.
- Use concrete pads or brackets for proper support.
- Ensure adequate clearance around the unit for airflow.
- Secure the unit to prevent movement during operation.
- Confirm that the unit is placed in a shaded area if possible.
- Ensure the unit is elevated above potential flooding areas.
- Check that the location allows for proper airflow.
- Adjust the positioning if necessary for efficiency.
- Select appropriate insulation material for refrigerant lines.
- Wrap insulation securely around the lines, covering all exposed areas.
- Ensure that insulation is kept dry and free from damage.
- Seal any seams to prevent heat transfer.
- Attach the condensate drain line to the indoor unit.
- Ensure the drain line slopes away for proper drainage.
- Test the drain line for blockages or leaks.
- Verify that water drains freely and efficiently.
- Choose an appropriate location for the thermostat installation.
- Connect wiring from the thermostat to the HVAC unit.
- Follow manufacturer instructions for programming settings.
- Ensure the thermostat is level and securely mounted.
- Turn on the HVAC system and observe airflow from vents.
- Adjust dampers to achieve desired airflow balance.
- Check for any blockages that may affect airflow.
- Document airflow readings for future reference.
- Consult manufacturer specifications for refrigerant type and amount.
- Use appropriate charging equipment to add refrigerant.
- Monitor pressure gauges during charging process.
- Verify that the system is charged to the correct levels.
- Use a pressure gauge to test the refrigerant lines.
- Pressurize the lines and monitor for any drops in pressure.
- Inspect connections for leaks during the test.
- Document results for compliance verification.
- Install air filters according to manufacturer instructions.
- Integrate any UV lights or additional components as specified.
- Ensure all components are securely mounted and connected.
- Test functionality of additional components after installation.
- Set the thermostat to the desired heating/cooling schedule.
- Adjust settings for energy-saving modes if available.
- Verify that settings are set according to user preferences.
- Test the programmed schedule for accuracy.
- Turn on the HVAC system and monitor its operation.
- Check for any unusual noises or vibrations.
- Verify that all components are functioning as intended.
- Document any issues for follow-up.
Electrical and Controls
Final Checks
- Examine all components for proper placement.
- Check for any visible damages or defects.
- Ensure that all safety measures are in place.
- Inspect insulation and sealing on ducts.

- Inspect duct connections for tightness and security.
- Check refrigerant line fittings for leaks.
- Ensure electrical connections are secure and insulated.
- Label all connections for future reference.
- Use gauges to confirm refrigerant pressure is correct.
- Use an anemometer to measure airflow at vents.
- Adjust dampers to achieve balanced airflow.
- Check for any obstructions in ductwork.
- Confirm that all registers are open and unobstructed.
- Evaluate temperature differences between supply and return.
- Set thermostat to cooling mode and monitor temperature drop.
- Switch to heating mode and check for heat output.
- Record temperature readings at various points.
- Evaluate system response time to thermostat adjustments.
- Ensure both heating and cooling coils are functioning correctly.
- Listen for unusual sounds during system operation.
- Inspect for loose components causing vibrations.
- Use a decibel meter to measure noise levels.
- Check the stability of the unit on its base.
- Address any excessive noise or vibration issues identified.
