Q&A
What's involved in a typical HVAC maintenance visit from MJS in Katy?
Our routine maintenance service is designed to keep your system running efficiently and catch small issues before they become major repairs. For Katy homeowners, this includes a thorough inspection of your air conditioner and heater, checking refrigerant levels, cleaning coils, testing electrical components, and calibrating your thermostat. We pay special attention to the air handler and ductwork, as these are common sources of efficiency loss in our local climate. This proactive service helps extend your system's lifespan, maintain good air quality, and prevent unexpected breakdowns.
How do I know if I need a full HVAC system replacement or just a repair?
This is a common question, and our approach is to provide a clear, honest assessment. During a diagnostic visit, we'll evaluate your system's age, efficiency, repair history, and your home's comfort needs. Generally, if your system is over 10-15 years old, requires frequent repairs, or causes uneven temperatures and high energy bills, a replacement may be the more cost-effective long-term solution. We'll explain all options, provide a detailed estimate, and discuss financing if a new, more efficient system is the best path forward for your Katy home.
My energy bills in Katy are high, and some rooms feel stuffy. Could this be a ductwork issue?
Absolutely. Duct leakage and poor insulation are very common issues in our area, leading to lost cool or heated air and reduced system efficiency—which directly impacts your monthly bills. We specialize in diagnosing these problems. Our technicians will inspect your ductwork for leaks, gaps, or poor connections, often using specialized tools. We can then recommend targeted sealing or, if necessary, duct replacement to ensure the air you pay to condition is delivered effectively throughout your home, improving both comfort and energy savings.
