Overview and Product Criteria
It is the responsibility of Certified Installers to adhere to the Palmetto AVL.
The AVL is organized into two parts:
HVAC AVL — approved parent/sub brands, minimum efficiency requirements, and warranty registration rules.
Accessories AVL — approved and non-approved air quality and system accessories.
For the avoidance of doubt, installations that do not adhere to the AVL, or that fall outside these categories, will not be approved or funded by Palmetto.
Product Criteria:
• All equipment must carry a minimum 10-year manufacturer’s warranty.
• The system must be an AHRI-certified match. Systems that are not an AHRI match will be rejected.
Minimum Efficiency Requirements:
13.4 seer2 for AC and Heat Pump
6.7 HSPF for Heat Pumps
80% AFUE for Gas Furnaces
No oil furnaces
Financing is not permitted for single pieces of equipment. Palmetto will only fund full systems.
Example: Replacing a condenser and coil, but leaving the existing furnace.

Accessories Definitions
Accessory Category | Description |
Air Filtration & Purification |
Click here for description An air cleaner, also known as an air purifier, is a device that removes contaminants from the air to improve indoor air quality. These devices are often used to help people with allergies or asthma, or to reduce secondhand smoke. They work by using a fan to pull air into the unit, where it passes through a filter to trap unwanted particles before the cleaned air is circulated back into the room.
|
Electronic Air Cleaners |
Click here for description Unlike traditional air filters that rely solely on a mesh or media to physically trap particles, an EAC uses an electrical charge to capture microscopic airborne contaminants.
|
UV System
|
Click here for description A UV system uses ultraviolet light to disinfect water, air, and surfaces by destroying the DNA of microorganisms, making them unable to reproduce and cause illness. This is a chemical-free method of sterilization. |
Bypass/Fan Powered Humidifier |
Click here for description A bypass humidifier is a type of whole-house humidifier that works with your HVAC system to add moisture to the air. It gets its name because it uses a "bypass" duct to divert a portion of the warm air from the furnace, pass it through the humidifier, and then reintroduce it into the main ductwork. |
Dehumidification |
Click here for description A whole-home dehumidification system is an air quality device that is integrated directly with your central HVAC system to remove excess moisture from the air in your entire house.
|
Zone Systems |
Click here for description An HVAC zoning system (or zoned HVAC) is a heating and cooling setup that divides a home or building into multiple independently controlled temperature areas, or zones. Unlike a traditional single-thermostat system that treats the entire structure as one area, zoning allows you to set and maintain different temperatures in different parts of your home, such as the upstairs, downstairs, or an infrequently used room.
