Trusted HVAC Repair in Evergreen Park, IL 60805 - Leahy Heating & Cooling

Short cycling is a common issue in our area, often caused by a clogged air filter, incorrect thermostat placement, or an oversized furnace. Our technicians start with a thorough diagnostic check of your system. We'll inspect the filter, thermostat, flame sensor, and heat exchanger to pinpoint the exact cause. For Evergreen Park homes, we also check that your furnace is properly sized for your space, as an older, oversized unit can lead to frequent cycling and higher energy bills.
