This is a very common situation with aging equipment in our area. Our approach is to perform a detailed diagnostic to identify the exact issue and its cost.

This often points to a faulty reversing valve, a key component that switches your system between heating and cooling. In our humid Missouri climate, these valves can wear out or get stuck. Our technicians are experts at testing the valve's operation and electrical controls. If a repair isn't viable, we can efficiently replace the valve to restore proper, efficient heating to your home.

Our maintenance service is designed to catch small issues before they become big problems, especially important for our local weather extremes. We perform a comprehensive checklist including cleaning coils, checking refrigerant levels, testing safety controls, lubricating moving parts, and inspecting electrical connections. This proactive care improves efficiency, prevents unexpected breakdowns, and extends the lifespan of your equipment.
