Patrick Heating and Cooling: Experienced HVAC Repair Serving Marthasville, MO 63357

A common culprit in our area is a faulty reversing valve, which is essential for your heat pump to switch between heating and cooling modes. When it gets stuck or fails, your system might blow cool air in winter. Our technicians perform a detailed diagnosis to confirm the issue and expertly repair or replace the valve, restoring your home's efficient and reliable heat.

Short cycling is a frequent problem we fix for Marthasville homeowners. It's often caused by an oversized unit, a dirty air filter restricting airflow, or a malfunctioning thermostat. This rapid cycling stresses your equipment and increases energy costs. We'll identify the root cause—whether it's a simple fix like a filter change or a more complex calibration—to ensure your system runs in longer, more efficient cycles.

For our local climate, the most critical step is biannual professional maintenance. Before winter and summer, we perform a comprehensive check, including inspecting electrical components, testing the reversing valve operation, cleaning coils, and verifying refrigerant levels. This proactive service catches small issues like a sticking valve or a dirty sensor before they lead to a full breakdown or inefficient short cycling, saving you from discomfort and costly repairs.
