We may ignore our home heating HVAC equipment all year long, but when it comes to the bone-cracking and chilly winters, the need for the heating furnace is exceptionally essential to keep us comfortable all this season. Just imagine, it’s a cold morning or the chilliest day of the year, you turned on your furnace and what you get is scold air instead of soothing warm air. Well, we all know this is nothing less compared to a nightmare. So, what to do? It’s obvious that you have to ask for professional heating repair in Fort Worth, TX, as earliest as possible. But, sometimes, the reason for your heating furnace blowing cold air can be easily discovered and self-fixed. We will check out some of the most common residential furnace problems that may cause it to blow cold air.
Check the Status of Your Thermostat Fan
Before you call your trusted heating repair in Fort Worth, TX, you should check the first potential reason why your residential furnace is blowing cold air, which is the status of your thermostat. Check whether the thermostat is set the fan to ON instead of keeping it to AUTO. In this scenario, the blower will operate on a continuous basis day and night and blows air into the property whether your furnace is on not. If you are getting warm air some times and cold air other times, you should check this point from the beginning. It might be a simple one, but no doubt could be an important one.
Another reason associated with the thermostat is its temperature setting. If your thermostat is set to cool, then it’s obviously going to blow cold air. Since users continuously make changes to the thermostat settings to cool in the summer or spring days or this might the first time they up to the HVAC equipment, they may have forgotten to switch on the heat in the thermostat or simply don’t know how to do it. The temperature settings can be easily searched online or asked the manufacturer support to perform, so no need to call a heating repair in Fort Worth, TX, before checking this.
Dirty Air Filter Invites Problems
Dirty air filters are one of the primary culprits for your residential heating equipment problems. Just remember when the last time you called an expert heating repair in Fort Worth, TX, to clean or replace it. As professionals suggest to change the air filters of home furnace systems once every ninety days if it’s frequently operating, the chances are great that you probably haven’t changed your air filters before the winter, or maybe in years even. A dirty air filter prevents good airflow to the primary functions of the furnace, causing the heat exchangers of your furnace to overheat and trip the max limit switch, which cutoffs the flames. As this is performed automatically by the furnace system to prevent overheating, heating coil cracking, and leak poisonous fumes into your property, the air handler will only blow cold air instead of heated air to your home. So, cleaning or replacing the air filter of your furnace is a must before the winters. We suggest you take professional help heating repair in Fort Worth to avoid other problems.
Check for Dirty Flame Sensor
Another common reason for your home furnace to blow cold air is a dirty flame sensor. This will result in your furnace is not heating up the coils. Usually, the furnace flame or spark ignites the gas that heats the coils in your home heating HVAC unit. The job of a flame sensor is to detect the flame, and if it successfully detects a flame, then it will keep the furnace running. If the flames fail to ignite, the furnace will not be able to detect whether or whether not to pour natural gas into it. With a dirty flame sensor, your residential heating unit will not work properly with the gas valves even if the flame is present there. This will ultimately result in your coils aren’t heating up properly or neither the air passing through it, resulting in blowing cold air into your property.
Check the Gas Line
Similar to the dirty flame sensor problem above, if your gas line is off, blocked, or has a leak (which are extremely dangerous), the flame won’t ignite properly. Simple to say, no flame means not hot air into your property. It’s highly recommended that if you even have a slight suspect or issue with your gas line, you must immediately call your gas provider as well as heating repair in Fort Worth, TX, for help.
Clogged Condensate Drain
The clogged condensate drain is another prime reason for which your residential heating unit might turn off or blow cold air. The air inside a heating unit works in a cyclical pattern. The furnace heats up the air and sends it to the property. As the air cools down, it goes back into the return vent so that it can be heated once more. The humidity present in the air hits inside the furnace, it evaporates into the gas and settles on the sides of the heating unit. After you turn off the coil, the settled air forms water droplets, which will run down to the bottom of the furnace, where a drain is present to take it outside. This drain is called the condensate drain. If this drain line is clogged, most of the residential furnace units will automatically turn off the whole furnace as a safety precaution. So, make sure to check whether the condensate drain is clogged or not. If it’s clogged, take the help of a trusted and professional heating repair in Fort Worth, TX, to solve the issue affordably.
