What is the EPA?

EPA stands for Environmental Protection Agency, and is an agency created for the protection of health and the environment. The EPA is responsible for writing and enforcing regulations designed to protect the environment and limit emissions, and preserve and create a sustainable future.

What does this have to do with HVAC?

The EPA provides a list of all EPA Certified furnaces, air conditioners and other HVAC systems products. When looking for a system, you should ensure that it is certified by the EPA and meets emissions standards which are based on the following criteria: fuel usage, annual average emission rateĀ (lb/mmBtu), maximum heat output ratingĀ (Btu/hr), efficiency (%HHV or APUE) and carbon monoxide emissions.

Browse the EPA website for more rules and regulations pertaining to heating and cooling, and check whether your current HVAC system meets requirements for your region.
