HVAC: Approved Vendor List (AVL)

Certified Installers are responsible for adhering to the Palmetto AVL.

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.

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

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.


🔴 Non-Approved Accessories

The following items are not approved for Palmetto installations:

  1. Hybrid Filter

  2. Steam Humidifier

  3. ERV/HRV (Energy or Heat Recovery Ventilators)

Consumables aren't covered and they have no warranty, but they can still be installed.
