Heater Repair Tips In Austin
In Austin, we typically rely on our air conditioners to beat the heat, but when cold fronts hit, it’s our furnaces that take center stage. However, what happens when your furnace starts blowing cold air instead of providing the cozy warmth you expect? It could be caused by a number of issues:
- Thermostat issues
- Dirty air filters
- Overheating furnace
- Ignition or pilot light problems
- Leaking ducts
Champion AC & Plumbing understands that cold air from the heater can mean you’re in need of timely furnace repair or maintenance. Let’s learn what the top causes of cold air blowing from the heater are.
Thermostat Issues
One common culprit for a furnace blowing cold air is a thermostat set incorrectly. If your thermostat is set to the ‘ON’ position instead of ‘AUTO’, the fan will continuously run without blowing hot air. This may seem silly, but small mistakes like this happen all the time and can be easily fixed!
Switching to ‘AUTO’ should resolve this. If the problem persists, consider checking the batteries or even upgrading to a smart thermostat for more efficient furnace installation and control.
Dirty Air Filters
A frequently overlooked issue is a dirty air filter. When filters are clogged, they restrict airflow, causing the furnace to overheat and blow cold air.
Regularly changing your air filters every three to six months not only prevents this but also ensures better indoor air quality and furnace efficiency. Consider checking your air filter and inserting a new one to see if the problem is solved.
Overheating Furnace
If a furnace overheats, it can trigger the high-limit switch. This switch shuts off the burners to prevent damage or stop a potential fire hazard. When the burners are off, the furnace may continue to blow air without heating it, resulting in cold air being circulated.
Overheating can be caused by restricted airflow — due to dirty air filters or blocked vents — mechanical issues or a failing blower motor.
Ignition Or Pilot Light Problems
Modern furnaces typically use electronic ignition systems, which can fail and prevent the furnace from heating the air. In older furnaces with a pilot light, if the pilot light goes out or is not functioning correctly, the furnace won’t be able to heat the air.
Issues with the ignition system or pilot light can be due to a variety of factors, including faulty components, dirt and debris or a lack of fuel in gas furnaces.
Leaking Ducts
Leaking ducts can significantly reduce your furnace’s efficiency. Holes or gaps in the ductwork allow heated air to escape, leading to your furnace producing cooler air.
Identifying and sealing these leaks can be a DIY project using HVAC tape or duct sealant, but for extensive issues, professional Austin furnace repair services are recommended.
The Importance Of Timely Heater Repair
Ignoring minor issues with your heating system can lead to bigger, more costly problems down the line. Early signs of heater malfunction — like cold air blowing — could indicate a larger problem.
Timely intervention by experts ensures your comfort during cold spells and also extends the life of your heating system. Remember, prompt heater service is the key!
