Warranty cycle time of 3 days is not bad at all. Of course, you should be tracking different types of warranty with different planned response times. Your “normal” warranty call with a response time of 3 days is not bad. Most builders are striving for 2 days. But, your “emergency” warranty calls (burst pipe, no heat, popping breakers) should have a target of immediate or less than 4 hours. Tracking these cycle times is very important to customer satisfaction and loyalty. A customer can’t be loyal if they are not confident that you will take care of them. In this world of immediate response, be sure you have a touch point of phone call or email prior to being able to get a tech to the home. Communicate who is coming and approximately when.
