How long must an HVAC service company keep records for each disposed appliance with a charge between 5 and 50 pounds?

An HVAC service company is required to retain records for each disposed appliance that contains a refrigerant charge between 5 and 50 pounds for a minimum of three years. This requirement is part of the regulations established under the Environmental Protection Agency's (EPA) policies, ensuring that service companies keep accurate records for compliance purposes, tracking the proper handling and disposal of refrigerants, and helping to minimize environmental impacts associated with refrigerant emissions.

Having comprehensive records aids in monitoring and verifying that companies comply with the regulations regarding the recovery and recycling of refrigerants, which is critical in protecting the ozone layer and reducing greenhouse gas emissions. Such documentation also facilitates inspections and audits by regulatory bodies, ensuring that all legal responsibilities are met in handling refrigerants.
