Licensed HVAC Repair in Mammoth Lakes, CA 93546 - MCR Services

Both are common issues here. Refrigerant leaks reduce cooling efficiency and can damage the compressor, while dusty conditions can quickly clog evaporator coils, restricting airflow. Our technicians perform a thorough diagnostic to pinpoint the exact cause—whether it's locating and sealing a leak per EPA guidelines or performing a professional coil cleaning—to restore your system's performance for our dry, high-altitude climate.

Our maintenance service is a comprehensive check-up designed to prevent problems and extend your system's life. We inspect electrical connections, test system controls, check refrigerant levels, clean critical components like coils and blowers, and ensure all moving parts are lubricated. For Mammoth homeowners, we pay special attention to components strained by temperature swings and dust. This proactive care improves efficiency, reduces the chance of sudden breakdowns, and helps maintain your manufacturer's warranty.

We recommend considering replacement if your system is over 10-15 years old, requires frequent and costly repairs, or struggles to maintain comfortable temperatures efficiently. In Mammoth Lakes, an outdated system can lead to high energy bills, especially during cold snaps. We'll provide a straightforward assessment, comparing the cost of continued repairs against the long-term savings and improved reliability of a new, properly sized system. We guide you toward the most practical and cost-effective solution for your home.
