Reasons Your House Isn’t Getting Warm: Heating System Problems

Reasons Your House Isn’t Getting Warm: Heating System Problems If your house doesn’t stay warm in winter, the heating system is failing to fulfill its most basic function. A number of system components operate in concert—or not—to produce reliable heat that consistently maintains thermostat settings. Causes of an under-performing heating system frequently extend beyond the furnace itself.

Becoming acquainted with the main suspects in heating shortfalls can help you resolve some simple issues yourself, as well as know when to call in professional HVAC service.

Furnace Problems

  • Short cycling. If a furnace turns on and off rapidly, it won’t generate heat long enough to adequately warm the house. Short cycles can result from a safety switch shutting down an overheated furnace. Also, a defective flame sensor may not sense the burner flame consistently and turn off the unit. For safety reasons, these issues require the expertise of qualified HVAC technician
  • Thermostat malfunctions may shut off the furnace before the setting has been reached, or produce erratic temperatures. Most defective thermostats are replaced, not repaired.
  • Improper sizing. If the furnace was not properly sized to the heating load of the home at installation, BTU output may be ether insufficient or excessive. Both under-sized and over-sized furnaces tend to provide disappointing performance as well as increased operating costs as long as the unit is installed.

Low Airflow Issues

  • A clogged furnace air filter is one thing you can check yourself. The filter should be checked monthly and replaced if it is dirty. Otherwise, replace the filter every other month during the heating season.
  • Are all supply vents fully open in every room? Vents may be closed for a variety of reasons at other times of the year then not re-opened. Also, vents closed in certain rooms only can unbalance airflow throughout the entire system, resulting in poor heating results.
  • Leaky deteriorated ductwork may lose warm air before it reaches rooms. Residential ducts that haven’t been tested and sealed can be assumed to leak at least 20% of conditioned air.
