Schedule a professional HVAC inspection before your tenant moves in. A licensed technician should check refrigerant levels, clean the evaporator and condenser coils, inspect electrical connections, and test the thermostat. This visit typically costs $80–$150 and can catch a failing component before it becomes a $3,000 emergency replacement.

Once safety is confirmed, shift your focus to maintenance. Every issue you fix now is one less emergency call you will receive later. A well-maintained property not only attracts higher-quality tenants but also prevents small problems from becoming expensive repairs.
