A heater blowing cold air can quickly turn a cozy space into an uncomfortable one. Here in Sparks, NV, it gets chilly at night, and cold air from your heater makes the evening downright frigid. Understanding the reasons behind this issue can help you identify the problem and determine the next steps to restore warmth to your home. Let’s explore some common causes.
Incorrect Thermostat Settings
One of the simplest issues could be your thermostat. If it’s set to “ON” rather than “AUTO,” the fan will continue to blow air, even when the heater isn’t actively warming it. Switching to “AUTO” ensures the fan runs only when the furnace is producing heat. Also, double-check the temperature setting to confirm it’s high enough to trigger the heating system.
Dirty Air Filters
Clogged air filters can restrict airflow, causing your heater to work harder and less efficiently. This can lead to uneven heating or cause the system to overheat and shut off prematurely, leaving you with cold air. Regularly replacing or cleaning your filters can prevent this issue and keep your heater running smoothly.
Pilot Light or Ignition Issues
For gas furnaces, a faulty pilot light or ignition system can prevent the heater from warming air. A blown-out pilot light, dirty flame sensor, or malfunctioning ignition can stop the furnace from producing heat. These issues usually require professional attention to fix safely and effectively.
Leaking Ductwork
If your heater is functioning but the air coming through the vents is cold, leaking ductwork might be the culprit. Gaps or cracks in your ducts can allow warm air to escape before it reaches your living spaces. This not only impacts comfort but also wastes energy.
When to Call a Professional
