  2. Which ASHRAE standard sets minimum energy efficiency requirements for residential HVAC equipment in the United States?

    Answer: ASHRAE 90.1

    ASHRAE 90.1 establishes minimum energy efficiency standards for HVAC equipment, and residential equipment must meet these as a baseline for code compliance.

  3. What does the AHRI Certification Program verify for residential air conditioning equipment?

    Answer: Published capacity and efficiency ratings are accurate

    The AHRI Certification Program independently tests and verifies that manufacturers' published capacity and efficiency ratings match actual performance.

  4. Which federal regulation requires HVAC technicians to be certified before purchasing refrigerants in containers larger than 2 pounds?

    Answer: CAA Section 608
