  1. Assessment and Consultation: The first step in replacing your HVAC unit is to schedule an assessment and consultation with a licensed HVAC contractor. During this visit, the contractor will evaluate your current system, assess your home's heating and cooling needs, and discuss your preferences and budget constraints. Based on this information, they will recommend the best replacement options tailored to your specific requirements.

Factors such as square footage, insulation levels, climate, and occupancy will be taken into account to ensure optimal performance and energy efficiency. You'll have the opportunity to select a system that meets your comfort preferences and budgetary constraints.
  3. Removal of Old Unit: On the day of installation, the HVAC technicians will begin by removing the old unit from your home. This involves disconnecting and safely disposing of the existing equipment, including the furnace, air conditioner, and any associated components such as ductwork or thermostats.
  4. Installation of New Unit: With the old unit removed, the HVAC technicians will proceed with the installation of the new HVAC system. This typically involves positioning the new equipment in the designated location, connecting ductwork and refrigerant lines, and configuring the system for optimal performance. The installation process may take several hours to complete, depending on the complexity of the system and any additional components or features.
  5. Testing and Calibration: Once the installation is complete, the HVAC technicians will thoroughly test the new system to ensure it is functioning correctly. This includes verifying airflow, temperature control, and system efficiency. They will also calibrate the system to ensure it meets manufacturer specifications and your desired comfort settings.
  6. Instruction and Maintenance: Before leaving your home, the HVAC technicians will provide you with instructions on how to operate and maintain your new HVAC system. This may include information on adjusting thermostat settings, replacing air filters, and scheduling routine maintenance to keep the system running smoothly. They will also address any questions or concerns you may have about the new equipment.
