The building inspector may also request to be on site to witness testing by the contractor and/or HERS rater. The installer picks one of the four options on the CF-1R-ALT-HVAC Form that describe the work being conducted. Each option lists the forms required to be at the job site for final inspection.
•CF-6R Forms shall be completed and submitted by the installing contractor for final inspection.*
•CF-4R Forms shall be completed, registered with an approved HERS Provider (cannot be completed by hand), and submitted by the HERS Rater for final inspection effective January 1, 2010.
DESCRIPTION OF HERS TESTS BELOW (Full descriptions found in Residential Appendix RA3 and Residential Manual)
Duct sealing – The installer is to insure leakage of the HVAC system is less than 6% for new air conditioning system (new equipment and all new ducts) or 15%, 60% reduction, seal all accessible leaks, etc. for alterations to existing HVAC systems. When the contractor uses the option to seal all accessible leaks, all easily movable objects must be moved to seal existing ducting. New ducting installed by the contractor is not allowed to have any leaks even if it is no longer accessible. In example 3 of the CF-1R “all new ducts” means that all the ducting was changed. The original boots, plenums, etc. do not need to be changed.
Cooling Coil Airflow (CCA) – There are two different minimum air flow requirements that must be met. These are 300 CFM and 350 CFM. The minimum 300 CFM per ton of cooling is required in order to conduct a refrigerant charge test. For new HVAC systems (new equipment and new ducts) the HVAC system must move a minimum 350 CFM of air for each ton of cooling.
Refrigerant Charge (RC) – The installer is required to verify the charge is correct. If the outside temperature is below 55 degrees then the weigh in method must be used by the installer. When the weigh in method is used the HERS rater must retest when the temperature is 55 and above. A charge indicator display (CID) can be used in place of conducting an RC, manufacturers are currently developing this device.
Temperature Measurement Access Holes (TMAH) – Installer must drill and mark holes to measure temperature split.
Hole for the placement of a Static Pressure Probe (HSPP) or Permanently installed Static Pressure Probe (PSPP) – Either the installer must drill and mark holes to measure static pressure or a permanently installed pressure probe must be installed and marked. Saturation Temperature Measurement Sensors (STMS) – Permanently installed type K thermocouple are installed on the indoor and outdoor coil so that the HERS rater can verify charge without attaching gauges. Instructions are found in Ch 4 of the Res. Manual. Fan Watt Draw (FWD) – Installer verifies that the furnace fan watt draw is less than 0.58 Watts/CFM.
NOTE: The CF-6R-MECH-04 is required for all HVAC alterations.
*For Final inspection ALL compliance forms (CF-1Rs, CF-6Rs, and CF-4Rs) shall be registered with an approved HERS Provider for building permit applications submitted on or after October 1, 2010.

Don't:
When it comes to HVAC systems and alterations in residences within Climate Zones 10 to 15, there are several misconceptions about the CF-1R-ALT-HVAC form and its requirements. Let's clear up some of these misunderstandings:
Permits are optional for minor HVAC work: Contrary to what some may believe, a written construction permit is necessary before starting most HVAC projects, including new installations, relocations, changeouts, and even replacing more than 40 feet of ducting.
All HVAC equipment shares the same efficiency requirements: This is not the case. Specific minimum efficiency standards, such as 78% AFUE for heating equipment and a minimum of 13 SEER for central air conditioners and heat pumps, must be met. Different types of equipment have different requirements.
Duct insulation is standardized: In reality, the required insulation value changes based on the amount of ducting being installed or replaced and the climate zone, ranging from R-4.2 up to R-8.
A setback type thermostat isn’t always required: This is a myth. A setback type thermostat is obligatory for all alterations, aiding in energy conservation by automatically lowering or raising the temperature when not home.
Sealing all ducts isn’t necessary: Actually, it's mandatory for all HVAC system alterations. Every joint and opening must be sealed with specific materials to ensure efficiency and compliance.
HERS verification is optional: A common misconception. HERS verification is mandatory for all HVAC alterations in specified climate zones to ensure the system meets certain energy efficiency and performance criteria.
Any form of documentation is acceptable for final inspection: Incorrect. Specific forms, such as CF-6R and CF-4R, must be completed correctly and present at the job site for the final inspection to confirm compliance.
Refrigerant charge tests are always necessary: While ensuring the correct refrigerant charge is crucial, the method, such as using a weigh-in method or a charge indicator display, can vary based on situational factors like outside temperature.
All duct sealing improvements meet the requirements: To meet requirements, duct sealing must reduce leakage to less than 6% for new systems or achieve a significant reduction for alterations. Simply sealing accessible leaks without meeting these criteria doesn't suffice.
Compliance forms don’t need to be registered: For building permit applications submitted on or after October 1, 2010, all compliance forms, including CF-1Rs, CF-6Rs, and CF-4Rs, must be registered with an approved HERS Provider for final inspection readiness.
Understanding these points can help ensure that HVAC projects are completed effectively, in compliance with regulations, and without unnecessary delays or fines. Always consult the latest guidelines and seek professional advice where necessary.
Filling out and using the CF-1R-ALT-HVAC form, which deals with Residential HVAC Alterations for Climate Zones 10 to 15 under the 2008 Building Energy Efficiency Standards, requires careful attention to a range of details.
