Fans and dehumidifiers have been running non-stop at Battlefords Union Hospital this week after the air conditioning system broke down on Monday.
It meant conditions were a little uncomfortable for patients, with temperatures a few degrees above normal room temperature.
Another issue was that too much heat and moisture can make it difficult to keep everything sterile.
At least 22 elective surgeries were postponed.
Staff were also concerned that warmer temperatures could cause problems for blood transfusions.
Everywhere else in the hospital it's been business as usual, so far.
Earlier this week, attempts to fix the air conditioning failed. It turned out the motor that drives the fan in a cooling tower had to be replaced.
A crane was being brought in to lift out the motor Friday morning.
If everything works, there could be some relief from the heat for the weekend.
