Signs of improper installation in our area include uneven heating or cooling, frequent short cycling, unusually high energy bills, and excessive noise. These issues often stem from incorrect sizing, poor ductwork, or faulty setup. Zagros provides a thorough diagnostic inspection to identify installation errors and offers precise corrections to ensure your system runs efficiently and reliably.

A malfunctioning thermostat is a common issue here, often caused by wiring problems, dead batteries, calibration drift, or location (e.g., in direct sunlight or a drafty hallway). First, try replacing the batteries and ensuring it's level and clean. If problems persist, our technicians can diagnose the issue, recalibrate the unit, repair wiring, or recommend a modern, programmable upgrade for better control and energy savings.

A proper installation is critical for our local climate. Our process includes a detailed load calculation to correctly size your system, ensuring it's neither too large nor too small. We then focus on precise placement, sealed and insulated ductwork, correct refrigerant charge, and thorough system testing. We also ensure your new thermostat is optimally located and programmed. This comprehensive approach prevents the common installation flaws we see and maximizes your comfort and system lifespan.
