The most common complaint against home warranty companies is their refusal to pay for repairs or replacements. Sometimes the refusal is valid—an exclusion or "rule" explained in the fine print that the customer overlooked. However, some disreputable companies have a reputation for avoiding payouts baselessly. Other home warranty complaints include slow response times, lousy repair work, poor customer service, and vague policy terms. Before buying a policy, be sure to read the fine print, so you know exactly what's covered—and what's not.
