Tomah High School took on a slight chill this week during a boiler replacement.

School district Business Manager Greg Gaarder said most of the building remained within a normal temperature range but that a couple of rooms dipped below 68 degrees.

“We had only two rooms outside our normal temperature guidelines,” Gaarder said.

Gaarder said the library dropped to 66.7 degrees, and the welding and band rooms fell to 66 degrees.

High school principal Marlon Mee said he hadn’t fielded any complaints.

“I don’t think it has been that bad,” Mee said. “It’s tough to judge this week because it’s homecoming and students have been dressed in goofy clothes all week.”

It was coldest Wednesday morning, when overnight temperatures in Tomah plunged into the upper 30s, but Mee said the building heated up quickly as the sun came out.

Gaarder said the boilers normally aren’t turned on at the high school until after Oct. 1 and that most boiler replacements are done in either early October or early April. He said this fall’s temperature fluctuations have been unusual. The first three weeks of the month were significantly above average with a sharp drop in the final week.

He said the transition from air conditioning to heat is more gradual in a large building like a high school than in a typical residential unit.
