Upstate Parts & Supply | Licensed HVAC Repair in East Syracuse, NY

Short cycling is often caused by a faulty flame sensor, a clogged air filter, or an overheating limit switch. We can help you identify the correct replacement part, like a specific flame sensor for your furnace model, to restore proper operation and prevent wear on your system.

Start by upgrading to a high-efficiency air filter that captures more allergens and particulates common in our area. We also stock compatible UV light systems that can be installed in your ductwork to neutralize mold, bacteria, and viruses, significantly improving the air your family breathes.

It could be either. We recommend first checking for a simple thermostat battery replacement or recalibration. If the problem persists, it may be a failing component like a capacitor or contactor. Bring in your old part or your system's model number, and we'll help you find the exact match to get your comfort back on track.
