HVAC Services Ontario CA | Call AMA Heater and A/C Repair

Yes, dirty evaporator coils are a frequent problem in our area, especially in aging systems. Dirt and debris act as insulation, preventing the coil from absorbing heat efficiently and forcing your system to work harder. At AMA, our diagnostic process specifically checks for this. We don't just clean the coil; we investigate why it got dirty (e.g., clogged filters, airflow issues) to prevent a quick recurrence and improve your system's overall efficiency and lifespan.

Our foundation is built on providing honest, knowledgeable solutions. For appliance repair, this means we start with a thorough diagnostic to understand the true cause of the failure, not just the symptom. We explain our findings clearly before any work begins, ensuring you can make an informed decision. We use high-quality, long-lasting parts and stand behind our labor, so you get a reliable repair, not just a temporary bandage.

When we install a new HVAC unit or replace major parts, our warranty covers both the labor and the parts we provide for 3 years and 10 years respectively*. This reflects our confidence in the quality of the equipment we select and our professional installation. To keep this warranty valid, we recommend an annual residential maintenance agreement, which helps prevent common issues and ensures your system runs efficiently year-round. *Carrying an annual residential maintenance agreement.
