Castle Cooling: Local HVAC Repair Serving TUCSON, AZ 85710

An overheated compressor is a common issue in our intense desert climate, often caused by restricted airflow, low refrigerant, or excessive strain. First, turn the system off to prevent further damage and check for blocked return vents or a dirty air filter. For a safe, lasting repair, our technicians diagnose the root cause—whether it's a failing capacitor, a refrigerant leak, or system undersizing—and perform the necessary service to restore efficient cooling and protect your equipment.

No, we do not. Castle Cooling believes in providing reliable service when you need it most, without requiring any long-term contracts.

We prioritize getting your comfort back online quickly and professionally.

Signs of a clogged drain line include water leaking from your indoor AC unit, musty odors, or the system shutting off as a safety precaution—a frequent issue in our dry, dusty environment. Our technicians perform a thorough cleaning of the primary drain line and the safety pan, using specialized tools to clear algae, mineral buildup, and desert debris. We also offer preventative maintenance tips to help avoid future clogs and potential water damage to your home.
