HVAC Services Carol Stream IL | Call Rand Heating and Cooling

Short cycling is a common issue here, often caused by a clogged air filter, improper airflow, or a faulty thermostat. It strains your system and increases energy bills. Our technicians perform a comprehensive diagnostic to pinpoint the exact cause—whether it's a simple cleaning, ductwork adjustment, or component repair—to restore normal operation and prevent further damage to your furnace.

This imbalance, common in older homes, is usually due to air trapped in the lines, a failing circulator pump, or uneven pressure. Rand's experts specialize in radiator system servicing. We'll bleed the radiators to remove air, check the pump and boiler pressure, and balance the system to ensure consistent, comfortable heat is delivered to every room in your house.

We recommend a professional tune-up for your heating system every fall. Our preventative maintenance includes inspecting heat exchangers for cracks, cleaning burners and sensors, checking flue drafts, and testing safety controls. This service is crucial for catching small issues—like those that cause short cycling—before they become major repairs, ensuring your system runs safely and efficiently all season long.
