What date range is used to determine heat testing?

• A. January 1 through December 31
• B. October 1 through March 31
• C. April 1 through September 30
• D. May 1 through August 31

Answer: (B)

Heat testing is evaluated during the heating season, which NSPIRE defines as October 1 through March 31. This period covers the months when heating is necessary to keep indoor temperatures comfortable and safe, so testing focuses on whether the heating system can deliver adequate heat when outdoor temperatures are cold. Testing outside this window wouldn’t reflect typical occupancy needs for heating and could miss deficiencies. The other date ranges either span the entire year or cover warm months when heating isn’t required, so they aren’t used to determine heat testing.
