Fed up of the chill following you from bus to office towards home? Thank God you have a heating system installed! But yuck!! Imagine coming back to a furnace that doesn’t heat up! Or worse, it blows out cold air. Of course, this is the last thing on Earth that you could ask for on a cold snowing day. But wait, there should be some reason behind your heating system going haywire. You definitely would want to know that.
Common Reasons for a Furnace Blowing Out Cold Air!
Even a fairly good or new furnace can start blowing out cold air. As inconvenient as it may sound, most of the time the problem isn’t too big and can be solved by just checking the normal troubleshooting list. But if the issue gets serious and the regular change in settings doesn’t work to solve the problem, call Craig’s Gas & Plumbing for heater repairs in Melbourne. They know the minutest and trickiest problem that can occur in your heating system and have the right knowledge to tackle the same efficiently. Do check the reasons behind the cold air coming from your heater and get solving it before it freezes you all over.
- Incorrect thermostat settings — You probably have just bought a furnace and the thermostat setting still hasn’t been adjusted properly. Or you have just turned it ON while actually it should be switched to AUTO. Well, that is the first thing you should check when your heater isn’t doing the needful task expected from it.
- No oil in the tank — For the ones having oil fired furnaces, probably you just finished with the fuel supply. That is the reason the burner fails to produce heat and the blower keeps moving, giving out cold air.
- Overheated burners — If your air filters aren’t changed timely, it causes the furnace to overheat which automatically shuts down the burner. And thus, hot air isn’t blown out. Just changing the filters timely can easily solve the issue.\
- Valve issues— If your heating system isn’t cleaned for long, there is a very high chance of your valve being blocked due to dirt and debris. As soon as it gets cleaned, the system runs swiftly, and the blowing of cold air stops instantly.
- Faulty thermocouples — A thermocouple is a sensor in your heating system that controls the valve and ignition. If it turns off, or doesn’t work properly, even then your furnace gives out cold air. An expert in heating repair can always fix this issue in minutes.
- Clogged oil filter — An oil filter that is filled with dirt does get clogged and blocks the fuel supply in the system. This prevents the heating process and thus cold air blows from the furnace.
- Leaking ducts — Sometimes the furnace system works perfectly fine! But there is an issue in the duct. It may have holes that leaks the hot air when passing through the entire building. Getting the ducts checked in such a situation is extremely critical.
If these aren’t the issues with your furnace giving out cold air, do check its pilot light, flame sensor, gas burner, electronic ignition, and drain lines. And if the issue overwhelms you, do call a repairer for the task and enjoy a warm cosy time in your house even when it’s snowing outside.
