You can avoid several problems by hiring contractors to inspect and maintain your system regularly. They can detect faults early enough before they develop into huge issues. You need to have basic knowledge of common HVAC problems and their solutions to ensure a functional system.

You should hire a technician to clean drain lines, inspect them to know the source of the water leak, and repair them.
