There are common reasons why a house may be colder than it should be during the winter months when the furnace or heating system is running. For example, there may be drafts that haven’t been identified and corrected. In other cases, a cooler home could indicate a problem with the furnace itself. Heating and cooling technicians in Minnetonka help detect furnace problems and identify repairs necessary to boost performance.
Common reasons for system failures
The flame sensor may simply need cleaning if the system starts to blow warm air during the initial stages before starting to turn cold altogether. The flame sensor can become dirty, which prevents the gas burner from functioning. A problem with the ignition system could also result in cooler air. The furnace’s inability to light the fuel properly leads to cooler air.
