Furnace Repair near 38th Ave NE. I received a call from a customer who reported that their furnace wasn't turning on. I arrived at the customer's house and inspected the furnace. I found that the pilot light was out, which was preventing the furnace from igniting. I relit the pilot light and checked the furnace's components, including the blower motor, heat exchanger, and air filter. I found that the air filter was dirty, which was causing the furnace to work harder than necessary. I replaced the filter and tested the furnace, confirming that it was now working correctly.
