Common HVAC & Plumbing Questions From Mahomet Homeowners
We recommend scheduling AC maintenance in spring and furnace maintenance in fall to prevent breakdowns during heavy seasonal use and extend system life.
This is usually caused by airflow restrictions, dirty burners, thermostat issues, or a failing blower motor. Our technicians can diagnose the problem quickly and restore heat.
Warm air, short cycling, ice on the system, or loud operation typically point to airflow or mechanical issues—not just low refrigerant. We pinpoint the exact cause.
Tree roots, aging sewer lines, hard water buildup, and heavy soil movement are common in Mahomet. A camera inspection helps us determine the real cause.
