HVAC Short Cycling

Professional HVAC Short Cycling in Asheville & Western NC

Short cycling — when your HVAC system turns on, runs for only a few minutes, and then shuts off before reaching the set temperature, only to start again shortly after — is a significant problem that wastes energy, causes excessive wear on your compressor and other components, and leaves your home uncomfortable. Quality Comfort diagnoses and resolves short cycling throughout Western North Carolina. The most common causes include an oversized system (the most common cause — a system that's too large for the space cools or heats too quickly, triggering the safety shutoffs before a full cycle completes), a refrigerant leak causing low pressure safety controls to cycle the system, a dirty air filter restricting airflow and triggering the limit switch, a failing thermostat, or a malfunctioning control board. Proper diagnosis requires understanding the system's history and current performance — not just a quick look.
