Frequently Asked Questions

What are the early warning signs that my aging HVAC system needs attention?

For aging systems common in Bel Air homes, key signs include inconsistent temperatures between rooms, unusual noises like rattling or banging, a sudden spike in your energy bills, and frequent cycling on and off. Addressing these early with a professional inspection from County Cooling and Heating can prevent a complete breakdown and extend the life of your equipment.

My heat pump isn't switching to heating mode; could it be the reversing valve?

Yes, a faulty reversing valve is a common culprit when a heat pump is stuck in one mode. This valve is responsible for changing the flow of refrigerant to provide heating or cooling. Our technicians can diagnose if the valve is stuck, leaking, or has an electrical fault, and perform the precise repair to restore your system's full functionality.

What maintenance can help prevent major HVAC problems in our Maryland climate?

Proactive, bi-annual maintenance is crucial. Before summer and winter, we recommend a professional tune-up that includes cleaning coils, checking refrigerant levels, inspecting electrical components, and testing the reversing valve and other critical parts. This service helps catch small issues—common with age and seasonal strain—before they lead to costly repairs and uncomfortable emergencies.
