Residential HVAC Replacement/Installation. 1. In-Home Evaluation
- A technician visits the home to assess the current system, measure the space, and determine heating/cooling loads.
- Ductwork is inspected for leaks, proper sizing, and condition.
2. System Selection
- Based on the home’s size, insulation, climate, and the homeowner’s preferences, the right system is recommended (e.g., central air, heat pump, furnace + AC combo).
- Energy efficiency, noise level, and smart features are often considered.
3. Removal of Old Equipment
- The existing unit is safely disconnected and removed.
- Refrigerant is recovered properly (EPA required).
4. Installation of New System
- New indoor and outdoor units are installed (air handler/furnace and condenser).
- Refrigerant lines, drain lines, wiring, and thermostat are upgraded or replaced as needed.
- Ductwork modifications are made if required.
5. Startup & Testing
- The system is charged with refrigerant, powered on, and tested for airflow, temperature, and pressure.
- Thermostat is programmed, and the homeowner is shown how to use the new system.
6. Final Inspection & Cleanup
- Everything is double-checked, and the area is left clean.
- Permits may be required depending on local code.
Commercial HVAC Replacement/Installation
1. Site Survey & Load Calculations
- Engineers or HVAC project managers inspect the building, analyze blueprints, and calculate loads for different zones or floors.
- Building usage, occupancy, and ventilation needs are all factored in.
2. System Design & Equipment Selection
- More complex systems are involved: rooftop units (RTUs), split systems, VRF/VRV systems, or chillers.
- Controls and automation (BMS/BAS) are considered for energy management.
3. Permitting & Coordination
- Permits and approvals are secured.
- Coordination with building owners, tenants, or other contractors is scheduled to minimize downtime.
4. Equipment Removal & Staging
- Old units are removed (sometimes using cranes for rooftop units).
- New equipment is staged, including ductwork, piping, control panels, and electrical upgrades.
5. Installation
- New units are installed with proper clearances and connections.
- Ductwork, gas lines, refrigerant lines, and power supplies are connected.
- Zoning and control systems are wired and programmed.
6. System Commissioning
- Systems are tested under load.
- Air balance reports, efficiency testing, and compliance with building codes are performed.
- Final walk-through with building management or owners.
