This is a common local issue often caused by thermostat malfunctions. The problem could range from simple calibration drift, dust buildup inside the unit, or wiring issues, to the thermostat's location being affected by direct sunlight or drafts. Our technicians will diagnose the specific cause—whether it needs recalibration, cleaning, or replacement—to restore precise temperature control and improve your comfort and energy efficiency.

For most homes in Lewisburg, we recommend checking your air filter every month and changing it at least every 90 days. However, if you have pets, allergies, or noticeable dust, you may need to change it every 30-60 days. A clogged filter is a frequent culprit for reduced airflow, strain on your HVAC system, and higher energy bills. Regular changes are a simple, effective way to maintain system health and indoor air quality.

Our preventative maintenance service is designed to catch and resolve local issues like thermostat irregularities and airflow restrictions. A thorough visit includes inspecting and calibrating your thermostat, checking and replacing air filters, cleaning system components, checking refrigerant levels, tightening electrical connections, and ensuring all parts are functioning correctly. This proactive care helps prevent costly breakdowns and keeps your system running efficiently throughout Kentucky's seasons.
