Health care HVAC systems serve facilities in which the population is uniquely vulnerable and exposed to an elevated risk of health, fire, and safety hazard. These heavily regulated, high-stakes facilities undergo continuous maintenance, verification, inspection, and recertification, typically operate 24/7, and are owner occupied for long life. The HVAC systems in health care facilities must be carefully designed to be installed, operated and maintained in coordination with specialized buildings services, including emergency and normal power, plumbing and medical gas systems, automatic transport, fire protections and a myriad of IT systems, all within a limited building envelope.

This report to the California Energy Commission's Public Interest Energy Research Program (PIER) helps Home Performance Contractors train their crews to achieve superior results in home energy retrofits. The book was updated and expanded in December of 2012 to include the impressive measured results from 15 home energy retrofits in Redding, California that were accomplished using the principles and practices outlined in this report. Homeowners may also find this information useful, when they want to understand the techniques that regularly achieve utility bill savings of 40 to 70% on an annual basis. This approach-called Measured Home Performance-is different from other means of saving energy. Most importantly, all of the home's energy features are redesigned and improved at the same time, so the synergies take effect immediately. Next, measurements are taken all the way through the process, to ensure that both the redesign and the installation are excellent. Improved comfort and energy savings are assured by high-tech field measurements, taken by the craftspeople themselves rather than by 3rd-party auditors. This process provides real-time feedback to the real decision makers-the technicians who do the work. Measurements of critical parameters like duct air leakage, while-house air leakage, supply air flow at each grill, CO concentration & draft pressure of combustion appliances and superheat and subcooling of the AC equipment make the installation quality-good or poor-are instantly clear to the crews. They can fix any shortcomings on the spot, rather than waiting days or weeks for 3rd-party testing results. Craftspeople measuring key parameters as they work transforms the workplace. Measured quality not only ensures successful results for the homeowners, it self-trains crew members in the field, where they learn more quickly than in the classroom. At the end of every day, workers know when they have achieved excellent results-a powerful motivator that works to everybody's benefit.

Introduction The purpose of this guide is to provide a comprehensive set of best practices for HVAC (Heating, Ventilation, and Air Conditioning) installations. These practices are designed to ensure optimal system performance, energy efficiency, safety, and customer satisfaction. Whether you are an HVAC contractor, installer, or technician, adhering to these guidelines will help you deliver high-quality installations that meet or exceed industry standards. Planning and Design Load Calculation: Perform accurate load calculations using recognized methods such as Manual J for residential and Manual N for commercial buildings to ensure the system is appropriately sized. System Selection: Choose HVAC systems that match the load requirements and consider factors such as energy efficiency ratings (SEER, EER, HSPF), environmental impact (refrigerant type), and client preferences. Ductwork Design: Design ductwork to minimize pressure losses and ensure balanced airflow. Use Manual D for residential duct design and ensure proper sizing and layout to prevent issues like hot and cold spots. Installation Best Practices Site Preparation: Ensure the installation site is clean, accessible, and complies with local building codes. Verify that there is sufficient space for equipment and maintenance access. Proper Mounting and Leveling: Mount and level all HVAC equipment correctly to prevent operational issues and enhance longevity. Use appropriate mounting hardware and check levels using a spirit level. Refrigerant Piping: Size and install refrigerant piping according to manufacturer specifications to prevent pressure drops and ensure efficient refrigerant flow. Insulate refrigerant lines to prevent heat loss or gain. Electrical Connections: Ensure all electrical connections are secure and comply with the National Electrical Code (NEC). Verify correct voltage and amperage, and install appropriate circuit protection devices. Duct Sealing and Insulation: Seal all duct joints with mastic or UL 181-rated tape to prevent air leakage. Insulate ducts in unconditioned spaces to improve energy efficiency. Ventilation Requirements: Install ventilation systems according to local codes and standards such as ASHRAE 62.2 for residential ventilation. Ensure proper placement of intake and exhaust vents to optimize air quality and system performance. Commissioning and Testing System Startup: Follow manufacturer guidelines for system startup procedures. Verify that all components are functioning correctly and that there are no abnormal noises or vibrations. Airflow Measurement: Measure and adjust airflow to meet design specifications. Use tools like anemometers or balometers to ensure balanced and adequate airflow throughout the system. Refrigerant Charge Verification: Verify that the refrigerant charge is correct using superheat and subcooling methods. Adjust the charge if necessary to ensure optimal system performance and efficiency. Maintenance and Documentation Maintenance Plan: Develop a maintenance plan that includes regular inspections, filter changes, and system tune-ups. Educate the customer on the importance of routine maintenance to prolong the system’s lifespan and maintain efficiency. Customer Education: Provide the customer with a detailed user manual and a walkthrough of the system’s features and maintenance requirements. Ensure they understand how to operate the thermostat, change filters, and recognize signs of potential issues. Documentation: Keep detailed records of all installation steps, system specifications, and any modifications made during the process. This documentation will be invaluable for future maintenance and troubleshooting. Safety and Compliance Code Compliance: Ensure that all installations comply with local building codes, safety regulations, and manufacturer guidelines. This includes securing necessary permits and passing all required inspections. Safety Protocols: Follow all safety protocols during installation, such as using appropriate personal protective equipment (PPE), ensuring proper ventilation when working with refrigerants, and maintaining a clean and hazard-free work area. Environmental Considerations: Dispose of old equipment and refrigerants responsibly, following EPA guidelines and local regulations. Consider recommending environmentally friendly options to customers, such as high-efficiency systems and eco-friendly refrigerants. Quality Assurance Final Inspection: Conduct a thorough final inspection of the entire HVAC system, checking for correct installation, proper operation, and compliance with all specifications. Customer Satisfaction: Ensure the customer is satisfied with the installation. Address any concerns or questions they may have before concluding the job. Warranty and Support: Provide information on warranties and support services. Ensure the customer knows who to contact in case of any future issues or questions. By adhering to these best practices, HVAC professionals can ensure high-quality installations that provide reliable, efficient, and safe heating and cooling solutions for their customers.
