This is called short cycling, a common issue in our area often caused by an oversized unit, a dirty air filter, or refrigerant problems. It strains your system and increases energy costs. Krug and Sons performs a detailed diagnostic to pinpoint the exact cause, whether it's a simple fix like cleaning the coils or a recommendation for a properly sized system, ensuring efficient and reliable operation.

Preventative maintenance is key. Our seasonal tune-ups include checking refrigerant levels, cleaning components that affect efficiency, calibrating your thermostat, and inspecting for issues that lead to short cycling.
