We will accommodate your schedule the best we can. A service technician will call you shortly and provide you with a tighter time frame than the 2-hour window you choose below. We also call 20-30 minutes prior to arrival. Please provide the correct model number so that we may know which parts to bring. This greatly improves the chances of a completed repair on the first trip. Although we do not charge extra for return visits with parts, we all want it fixed the first time.
