It might be a ductwork issue if your furnace is blowing hot air but your house is still cold. It's possible that your ducts are leaking or broken, allowing cold air to enter while hot air escapes. A system damper may occasionally become misaligned or come loose, unintentionally obstructing or reducing airflow.

Check your thermostat next if your ductwork checks out ok. If your central heat is blowing hot and cold air into the house and your furnace is on all the time this could be because the fan switch on your thermostat is set to “on” rather than “auto”. If this is the case the fan will run continuously, producing both hot and cold air. The temperature in your house will stay much cooler than desired if this is the issue. Set your thermostat fan to “auto” and wait a few hours to see if the temperature improves.

It might be time to call the pros if your home feels cold to the touch and your furnace is blowing. Sometimes all your system needs to function properly again is a good tune-up. Your system may operate more efficiently if the cobwebs are removed and all of the parts are in good condition.

An hour and a half to two hours may be needed for a furnace tune-up. The biggest factor, though, is the furnace's age. If your furnace is brand new and kept clean, it might go more quickly. However, no matter what the age if it is discovered that you require more substantial repairs, it will probably take longer. For instance, it shouldn't take long to relight the pilot light, but, it might take up to an hour or longer to replace or fix the electric ignition system and larger system parts like the blower motor.

The price varies from $100 to $200 depending on the furnace's fuel type, the cost of an inspection, the level of cleaning necessary, whether a filter change is necessary, and the labor costs associated with maintaining the furnace. If furnace repairs are necessary or if the homeowner decides to have their air ducts cleaned, the cost may go up. The cost may be covered by a home warranty, or the homeowner may decide to buy an annual maintenance plan from a reputable HVAC business.

To ensure your heating system is safe to operate, look for several key indicators:

• Unusual noises: Listen for loud bangs, rattles, or hissing sounds, which may indicate problems.
• Burning smells: Although most heating systems will give off a burning smell at the beginning of the heating season, a persistent burning smell could signal overheating or electrical issues.
• Inconsistent heating: Uneven temperatures throughout your home may suggest a malfunction.
• Yellow pilot light: A yellow or flickering pilot light on gas units may indicate unsafe combustion.
• Carbon monoxide detector: Ensure detectors are functional, as they alert you to dangerous gas leaks. If in doubt, consult a professional technician.
