HRN Services | Expert HVAC Services in Frederick, MD

A frequent issue we encounter in Frederick homes is a faulty heat pump reversing valve. This critical component is responsible for switching the refrigerant flow between heating and cooling modes. When it fails, you'll often get only hot or only cold air, regardless of your thermostat setting. Our HVAC technicians are experienced in diagnosing this specific problem. We'll perform a thorough inspection, check for electrical issues with the valve solenoid, and test refrigerant pressures. If a replacement is needed, we ensure the new valve is properly installed and the system is recharged to the manufacturer's specifications, restoring your home's year-round comfort efficiently.

A tripping circuit breaker is a common safety response to an electrical overload, a short circuit, or a ground fault. In older Frederick homes, we often find that the demand on a circuit has simply grown over time with added appliances and devices, overloading the wiring. Our licensed electricians start with a comprehensive inspection of your electrical panel, the affected circuit, and the connected outlets and fixtures. We'll identify the root cause, which could be anything from a faulty appliance to outdated wiring. The solution may involve repairing a specific fault, redistributing the electrical load, or upgrading the circuit or panel to safely handle your home's modern needs, ensuring reliable and safe power.
