Smoke coming from a house in the King George neighbourhood was reported next at roughly 2:20 a.m. on May 17, officials said.
Fire crews advanced hose lines to direct water at exposed flames on the south side of the house in the 800-block of Avenue M South.
A fire investigation determined the blaze was caused by an air compressor that had been running continuously, causing it to overheat and ignite nearby combustible materials.
Damage at the house was estimated by the fire department at $100,000.
