Design & Installation of a Residential HVAC System

Project Objectives

A residential HVAC system is essential for maintaining comfortable indoor air quality, temperature control, and energy efficiency. This project will guide students through the process of designing, selecting, and installing an HVAC system for a home, covering aspects like heat load calculation, ductwork design, refrigerant handling, and system troubleshooting.

The primary objectives of this project are:

  • Understanding the components of an HVAC system (compressor, evaporator, condenser, ductwork, etc.)
  • Learning heat load calculation to determine the required system capacity.
  • Designing an energy-efficient duct system with proper insulation.
  • Installing an air conditioning and heating system following safety standards.
  • Testing and troubleshooting performance issues for efficiency.

Heat Load Calculation & System Sizing

Utilizes Manual J Load Calculation to assess cooling/heating needs. Considers building size, layout, occupancy, window/insulation quality, and climate conditions. Determines appropriate HVAC unit tonnage and SEER rating.

Ductwork Design & Airflow Optimization

Develops an efficient duct layout for optimal airflow. Selects suitable duct materials such as flexible, sheet metal, or fiberglass. Installs air vents, dampers, and return air grilles while ensuring proper sealing to prevent air leakage and enhance efficiency.

HVAC System Installation

Mounts the outdoor (compressor/condenser) and indoor (evaporator) units. Connects refrigerant lines and electrical wiring. Charges the system with R-410A or R-32 refrigerant per EPA guidelines. Installs and calibrates the thermostat for temperature control.

System Testing & Troubleshooting

Balances airflow and checks duct pressure. Measures cooling efficiency using EER and SEER ratings. Inspects refrigerant levels for leaks and addresses common issues such as low cooling efficiency, refrigerant leaks, and electrical faults in the compressor or blower motor.

Required Tools & Materials

HVAC Components
  • Air Conditioner (Split/Packaged) 
  •  Thermostat (Programmable or Smart)
  •  Ductwork (Sheet metal/Flexible ducts)
  • Air Filters & Vents
  • Refrigerant Lines
  • Insulation Materials
Tools & Measuring Instruments
  • Digital Manifold Gauge (for checking refrigerant pressure)
  • Vacuum Pump
  • Leak Detector (for refrigerant leaks)
  • Multimeter (for electrical testing)
  • Duct Sealing Tape & Fasteners

Expected Outcomes

Upon completing this project, students will:

  • Gain hands-on experience in HVAC system design & installation.
  • Learn to perform heat load calculations for system sizing.
  • Understand the importance of energy efficiency and proper ductwork.
  • Develop skills in troubleshooting and refrigerant handling.
  • Be prepared for real-world HVAC technician roles in residential systems.

This project provides students with practical skills in residential HVAC design, installation, and troubleshooting. By learning system sizing, energy efficiency, and proper installation techniques, students will be well-equipped for a successful career in the HVAC industry.
