Finch Mechanical Contractors: Experienced HVAC Repair Serving San Marcos, TX 78667

Our maintenance service is designed to keep your San Marcos home's system running smoothly and efficiently. We perform a comprehensive check, including cleaning components, inspecting electrical connections, checking refrigerant levels, and calibrating your thermostat. This proactive care helps prevent common local issues like evaporator coil freeze-ups and can identify minor duct leaks before they impact your comfort and energy bills.

Several signs indicate it might be more cost-effective to consider a replacement. These include your system being over 10-15 years old, frequent and costly repairs, uneven heating or cooling, a noticeable increase in your energy bills, or the system struggling to maintain a comfortable temperature. As a family-owned business serving the area since 1974, we provide honest assessments to help you decide between repair and a new, more efficient installation that suits your home and budget.

In our local climate, two common culprits are duct leakage and evaporator coil issues. Leaky ducts in attics or crawl spaces can lose cooled air before it reaches your rooms. A frozen evaporator coil, often caused by restricted airflow or low refrigerant, also severely reduces cooling power. We specialize in diagnosing these specific problems, performing precise duct sealing, and addressing coil freeze-ups to restore your system's efficiency and your home's comfort.
