Vernon Heating & Air Conditioning | HVAC Services in McLean, VA 22101

Short cycling, where your system turns on and off too frequently, is often caused by an oversized unit, a dirty air filter, a malfunctioning thermostat, or refrigerant issues. It's a common problem in McLean homes that strains your system and increases energy bills. Our technicians will perform a thorough diagnosis to identify the exact cause and provide the necessary repair or adjustment to restore normal, efficient operation.

Signs it might be time for a replacement include frequent repairs, rising energy costs, uneven temperatures in your home, excessive noise, or if your system is over 10-15 years old. For McLean homeowners, we offer a detailed evaluation of your system's performance and efficiency. We'll provide a clear, honest assessment of your repair options versus the long-term benefits and savings of a new, high-efficiency system tailored to your home.

To prevent problems like short cycling and extend the life of your system, we recommend bi-annual maintenance. In the spring, we service your air conditioner, and in the fall, we service your furnace. This includes cleaning coils, checking refrigerant levels, testing safety controls, lubricating moving parts, and inspecting electrical connections. This proactive care helps catch small issues before they become major repairs, ensuring reliable comfort through Virginia's hot summers and cold winters.
