An important concern potential home warranty purchasers have is whether a certain warranty company has fast and efficient service response times. Although it varies based on the situation, the company, and the availability of service technicians, most service requests are responded to within 24 hours. The service contractor contacts you and schedules a time that works for both of you during normal business hours in the next few days. Although most warranty companies can be contacted 24/7 and you can file a claim online at any time, many of them will not actually provide service to repair or replace a broken system or appliance until normal business hours. Be aware that response times on weekends and holidays will most likely be different and take longer. Lastly, keep in mind that several companies allow you to request services online, eliminating the hassle of lengthy call wait times.
