About this service

Window units often face issues like clogged drainage, faulty thermostats, or damaged fans. If your unit is dripping water inside your home, rattling loudly, or failing to cycle on and off, it is time for service. In many cases, these units are cost-effective to fix if the issue is minor, like a bad capacitor or dirty coils. If the cooling system has lost its charge, it may be time for a replacement.
