Question Answers

What's involved in a typical HVAC installation or replacement for a Hillsboro home?

Our process begins with a thorough assessment of your home's size, layout, and existing ductwork to ensure we recommend the right system for efficiency and comfort. We handle the complete installation, including proper sizing, ductwork evaluation, and precise setup, followed by testing to ensure optimal performance. As a local, family-run business since 1988, we focus on installations that provide long-term reliability for our climate.

My heat pump isn't switching between heating and cooling properly. Is this a common issue here?

Yes, heat pump reversing valve issues are a frequent service call in our area, often due to wear or electrical problems that affect the system's ability to change modes. At Koch Mechanical Services, we diagnose the specific cause—whether it's the valve itself, a refrigerant issue, or a wiring fault—and provide a clear repair plan. With John's decades of local experience, we understand how seasonal demands strain these components and how to fix them efficiently.

How quickly can you typically respond to a repair call for my air conditioner?

As a local, family-operated company, we prioritize urgent repairs, especially during extreme Missouri weather. We strive for same-day or next-day service when possible. Our long-standing presence in Hillsboro since 1988 means we're nearby and can often dispatch our team quickly to diagnose issues like compressor failures or refrigerant leaks, getting your comfort back on track.
