Your Furnace is Blowing Cold Air: Three Possible Reasons
When the Ft. Smith nights get cold, you expect a working furnace, but what happens if all it blows is cold air? Knowing what causes a gas heating system to blow cold air is tough. It takes a great HVAC technician to find and repair the cause.
Side Note: You should never attempt to repair one of the problems mentioned below on your own. Your repair company will have the experience to do it safely and properly.
Your technician will attempt to light the pilot light two to three times, since false positives are not uncommon. Then, he will check the sensor for rust and dirt buildup. It is important to note here that with gas fuel comes water, which can rust the metals on the detector.
That is why the technician will look for rust buildup. If he finds any rust or dirt, removal of the detector is the next step. The professional will remove the sensor and clean it by scraping off any dirt or rust before returning it to its proper place. In the less likely event that the technician cannot clean the sensor because it is too rusted, he will get a replacement and insert that in the old one’s place.
The furnace is overheated.
Every furnace has motors that are necessary to the running of the heater. These motors can undergo stress which will lead to them overworking and eventually shutting down. Some of the causes of overheating systems are:
• Blocked air filter
• Blocked air vents
• Short cycling
There are also more complex reasons for a heating system to overheat. Your technician will go over each of these and determine what is causing the overheating. Hopefully, he will be able to fix the problem without replacing the furnace, but there is always the off chance that the furnace is simply too old or is a poorly made unit and needs replacement
It is very important that the system is warming your home properly, which is why it is essential that you call your HVAC company if there are any problems. This article has listed three of the most common reasons a furnace will stop working, but other reasons exist.
The experience and knowledge of a certified technician in Ft. Smith will create the right combination to help him find the challenge and repair it.
