What to Include With Your Request
Share what you can safely observe. There is no need to dismantle equipment or guess which component has failed.
What matters on site
Equipment, Safety and Access Details That Matter
These details explain what can change the repair or installation approach at the property.
Normal Repair Symptoms Versus an Emergency
No heat, repeated starts, blower problems and visible control codes can be submitted for repair review. If you smell rotten eggs or otherwise suspect an active gas leak, leave the area immediately and call 911 or Enbridge Gas from a safe distance.
What Happens After the Thermostat Calls for Heat?
Without opening equipment, note whether the furnace starts, whether the blower comes on, whether the system stops after a short period and whether the home receives warm air. These observations are safer and more useful than guessing an igniter, gas valve or control board.
Mechanical-Room Access in Ajax
Basement furnaces in South Ajax or Central Ajax homes can be reached very differently from equipment in a tighter townhouse utility area. Note stairs, side entrances, finished-room clearances and anything stored around the furnace that affects access.
