When you observe your furnace blowing cold air, it’s important to get to the bottom of the issue quickly. A furnace that blows cold air is no longer working properly, and it could be a sign of some serious problems. The sooner you can determine what’s causing your furnace to blow cold air and correct the issue, the more likely you are to prevent the problem from getting even worse.
There are a few problems you may be able to fix yourself, but it’s important to call a professional HVAC technician in Apache Junction if you can’t resolve things quickly. Here are four of the most common reasons your furnace could be blowing cold air.
1. Your Thermostat Is Set Incorrectly
Maybe someone bumped into it, maybe someone else in your house tampered with it, or maybe you just got confused. Check to make sure that your thermostat is set to an appropriate temperature, and also make sure that it’s set to “Auto” instead of “On.” When the thermostat is set on, it’s likely to blow all the time even if the furnace isn’t going.
2. Your Furnace Filter Needs a Replacement
Some furnace filters can be cleaned, while others have to be replaced. If you have an oil-fired furnace, this job can get messy, but it’s something you can easily do yourself for most furnaces. An excessively dirty filter can restrict airflow, which can prevent your furnace from passing heated air into the home.
3. Malfunctioning Flame Sensor in Furnace
If your furnace starts blowing warm air before turning cold, that could be a sign that your burner is shutting off because of the flame sensor. This might mean that your flame sensor just needs to be cleaned before your furnace can function properly again, or the sensor might need to be replaced.
4. Burner Problem in Furnace
This is one of the most common reasons you might notice a furnace blowing cold air. Essentially, the burner isn’t igniting because it’s too dirty. In extreme cases, the burner may completely malfunction. If you’re not completely sure about how to clean the burner in your specific unit, it’s probably best to call a furnace repair professional and let them take care of the issue.
How to Make Your Furnace Last Longer
When you find the right furnace repair company near Phoenix, you’ll be able to get a fast solution for any of the problems listed above. The best scenario, though, is to not need a furnace repair at all. Keep your HVAC system running as efficiently as possible by scheduling regular heater maintenance.
Getting a furnace tune-up will give a professional technician a chance to inspect your unit, make sure everything is functioning properly, and give it a good cleaning. This way, you’ll be able to take proactive measures that prevent minor problems from becoming big ones.
