Your washer and dryer are probably among the most important appliances in your home. While these units are built to last for many years after installation, you will need to maintain your washer and dryer with routine services from a professional repair company. One of the most critical services to perform on a routine basis is dryer cleaning. Dryer cleaning involves removing trapped lint from deep within the dryer vent. When your dryer vent becomes filled with lint and other debris, this could create a serious fire safety hazard in your home. Since dryer lint is highly combustible, excessive lint could catch fire when the unit is in operation.
