HVAC Services in St Peters, MO | Aire Serv of St Charles

In St Peters, we frequently handle thermostat malfunctions and heat pump reversing valve issues, especially during our variable seasonal transitions. For faulty thermostats, we diagnose whether it's a wiring, calibration, or power issue and provide a precise repair or recommend an appropriate replacement. For a heat pump stuck in one mode due to a reversing valve problem, we perform a thorough inspection to identify electrical failures or mechanical obstructions and execute the necessary repair to restore proper heating and cooling function for your home.

Our maintenance service is a comprehensive check-up designed to keep your system running efficiently and prevent future problems. We inspect and clean key components, check refrigerant levels, test system controls and safety devices, lubricate moving parts, and ensure proper airflow. This proactive care helps improve your system's performance, can extend its lifespan, and often helps us catch small issues before they turn into costly repairs.
