Heating Service FAQs
A heating system blowing cold air can be caused by:
- Thermostat settings: Check to ensure the thermostat is set to “heat” and the temperature is set correctly.
- Dirty air filters: Clogged filters restrict airflow and can cause the system to overheat and shut down.
- Pilot light issues: If you have a gas furnace, the pilot light may be out or malfunctioning.
- Ductwork problems: Leaks in your ducts can cause heated air to escape before it reaches your rooms.
Scheduling a professional inspection can quickly identify and resolve the issue.
Signs your heating system needs repair or replacement include:
- Frequent repairs: If you’ve repaired your furnace or heat pump multiple times in recent years, replacement may be more cost-effective.
- Age of the system: Furnaces typically last 15–20 years. If your system is older, replacement may be necessary.
- Uneven heating: Cold spots in certain rooms may indicate your system is struggling.
- Higher energy bills: A sudden increase in utility costs could mean your heating system is losing efficiency.
- Heating systems, whether furnaces, heat pumps, or boilers, should be serviced once a year, ideally in the fall before temperatures drop.
- Regular maintenance ensures optimal performance, extends the lifespan of your unit, and prevents costly repairs during the cold winter months common in Southern Illinois.
