Hilmer HVAC Services | HVAC Services in San Fernando Valley, CA 91340

This is a common issue we see in the Valley. Often, it's a wiring problem, a faulty thermostat, or a compatibility issue with your existing HVAC equipment. Our technicians will diagnose the root cause. In many cases, it's a repairable connection or a thermostat replacement, which we can handle efficiently. We'll only recommend a full system replacement if it's the most cost-effective, long-term solution for your home.

Absolutely. Duct leakage is a major culprit for poor airflow and high energy bills in our older Valley homes. During a maintenance visit or specific duct inspection, we use specialized tools to locate leaks in your attic or crawlspace. Our repair involves properly sealing these leaks with durable mastic sealant or metal-backed tape, not just standard duct tape. This restores proper airflow to every room, improves your system's efficiency, and enhances your overall comfort.

Our preventative maintenance is specifically designed for our local climate and common issues. We thoroughly clean components that affect airflow, check electrical connections that can cause thermostat problems, and inspect ductwork for early signs of leaks. This proactive care keeps your system running smoothly, catches small problems before they become major (and costly) repairs, and ensures your system doesn't have to work overtime during our hot summers, saving you money on energy bills.
