Common signs include reduced cooling power, ice forming on the evaporator coils, a noticeable hissing sound from the unit, and higher-than-normal energy bills. Refrigerant leaks are a common local issue that can damage your compressor if ignored. Our technicians use specialized tools to locate and seal leaks, then recharge your system to its manufacturer specifications to restore efficiency and protect your investment.

Not necessarily. Thermostat malfunctions are a frequent culprit for comfort issues and often don't require a full system replacement. We'll first diagnose if it's a simple thermostat wiring issue, a dead battery, or a faulty unit itself. Often, a thermostat upgrade or repair solves the problem. However, if your system is over 15 years old and inefficient, we can discuss replacement options that will improve comfort and lower your energy costs for the long term.

Our preventative maintenance service is designed to catch small problems before they become big, expensive ones. During a tune-up, we clean components, check refrigerant levels to prevent leaks, test thermostat calibration, and inspect electrical connections. This proactive care improves system reliability, maintains energy efficiency (saving you money), and extends the lifespan of your equipment, giving you peace of mind through Maryland's hot summers and cold winters.
