You need a professional gas furnace repair in Sachse TX, when your heating system does not work properly. Many homeowners in Sachse, TX, ignore regular gas furnace maintenance.
As a result, the system gets damaged, leading to higher energy bills and costly repairs. Most often, homeowners call Air Repair Pros and tell us, “why is my furnace not heating,” or “my furnace is blowing cold air.”
In today’s article, we will tell you why your furnace does not blow warm air and what you can do to fix the problem. Read on!
Common Reasons Why Your Furnace Is Not Blowing Warm Air
There are many reasons your furnace does not produce heat or warm air. Experts at Air Repair Pros understand homeowners’ frustration when their furnace systems don’t work properly to blow warm air. Here are a few common reasons!
A dirty, clogged filter can restrict airflow to the furnace system. As a result, it limits your heating system’s ability to produce and distribute heat throughout your home. Some furnace systems have a built-in shutoff, which kicks into action when the air filter gets dirty or clogged.
The purpose is to prevent an overheated burner. In such a situation, the furnace system will blow cold air. You can solve this problem by changing the air filters. If the problem persists, call gas furnace repair in Sachse TX.
If your furnace is blowing cold air instead of warm air, something is wrong with the thermostat settings. If the fan is set to “ON,” it will blow cold air. Changing the thermostat settings from “ON” to “Auto” will fix the problem.
Auto means that the furnace fan turns on automatically when the system is heating air. Once the system reaches the desired temperature, it will shut off until the next cycle. Check the thermostat batteries and change them if required.
Pilot Light Issues
A gas furnace contains a pilot light like a gas stove. If you have an old gas furnace, the pilot light likely gets blown out. Call a professional gas furnace repair in Sachse TX to solve the problem.
Our technician will turn off the thermostat and find the gas valve knob and turn it to select “pilot.” If it is sticky, he will use oil and then press the red button while holding a match to the burner. We recommend gas furnace maintenance at least twice a year to avoid such problems.
Gas Valve Issues
It is a gas furnace maintenance issue. If you have a gas furnace system that has not been cleaned for quite some time, a faulty valve can be the reason why your furnace is not blowing warm air.
Keep in mind that dirt, dust, and debris can collect on the value. These contaminants can cause the furnace system to shut down. If the valve is worn out, you need to replace it. Contact an experienced gas furnace repair in Sachse TX, like Air Repair Pros, to fix the problem.
The burner is another furnace component that is vulnerable to dirt, dust, and grime-related problems. When it gets clogged, the furnace system won’t get enough fuel to run and produce warm air.
Although the furnace’s fan will blow, it won’t produce warm air through ducts. The best solution is to clean the burner. If you don’t know how to clean it, you can contact expert technicians at Air Repair Pros. Our technicians are well-aware of gas furnace maintenance. Our technician will thoroughly clean the burner to make the furnace blow warm air.
Flame Sensor Issues
Another issue that can cause the furnace to blow cold air is a dirty flame sensor. If the sensor is not working properly because of the dirt or grime, the burner will keep shutting off. However, the fan may keep running, blowing the cold air that will circulate throughout the indoor space through ducts.
Regular gas furnace maintenance is the sole solution to get rid of dirty or grimed flame sensors. You can use a soft brush to clean the sensor. If the problem persists, call a professional technician to inspect the system, diagnose the issue, and resolve it immediately.
