Reasons why your furnace could be blowing cold air

Professional Sacramento furnace experts are likely to recommend that you check the following if your heater is blowing out cold air:

  1. The Thermostat: Yes you really do need to check the thermostat! While it may not
    seem like the thermostat could be the culprit behind the cold air problem, it is the first place that your furnace technician will check when inspecting the heating system. Is your thermostat set on the “auto” mode, or the “on” mode? You want the thermostat on the “auto” mode because that way, the heating system isn’t blowing air out continuously and instead only blows out the air when it is being heated.

  2. The Air Filters: When the air filters are not regularly cleaned out, they will eventually become clogged and a clogged air filter system can result in restricted airflow. This affects your furnace by causing the system to overheat and upon overheating, a furnace will stop producing hot air as a safety mechanism. How can you prevent this from happening? Simply remember to clean out the air filters every couple months to keep them from getting clogged!

  3. The Ductwork: The ductwork is the part of the heating system that the air passes through, basically the vents and other air duct that deliver air throughout your house.

This part of the furnace unit could be the reason behind your cold air problem if there are any connection issues or leaks, which lets the warm air leak out of the ducts instead of warming up your home. Not only does this make your home colder, but it also ends up hurting your pocketbook because it takes more time and energy to get the hot air inside. Should your ductwork need adjustments, it’s best to have your local Sacramento furnace expert handle it as such work requires some technical skills.

Additional things to consider…

  • Try not to crank up the temperature too high, or keep it at a high setting for a long period of time.
  • Program your thermostat to heat your home when you are there, and to go off when no one’s home, that way you don’t run the furnace unnecessarily.
  • Keep a regular maintenance schedule with your trusted Sacramento furnace company. An expert HVAC technician can spot furnace issues that can lead to cold air problems during the winter months, which means that you won’t have to worry about sitting in a chilly house with cold air coming out of your furnace this year!
