Why Is Your Furnace Blowing Cold Air? Troubleshooting Tips to Try
When a furnace suddenly starts to blow cold air, it can cause many homeowners concern, often because it is such an unexpected event. It's important to understand why your furnace is blowing out cold air, as well as how you can best troubleshoot the issue. This article provides a comprehensive guide to troubleshooting furnace issues that are causing cold air.
Assess the Health of Your Filter
The first step in diagnosing a furnace problem is to check the filter, as this can often be the source of the issue. If the filter has become clogged, air won't be able to pass through and reach the furnace blower. When the furnace blower isn't getting the hot air it needs to heat your home, it will simply blow out cool air instead. It is highly recommended to replace your filter every three months to ensure everything is running smoothly.
Confirm that the Furnace Is On
If your furnace filter is in good condition, the next step is to confirm that the furnace itself is working. Open up your furnace door and check that your flame sensor is lit and that electricity is running through the system. If either of these two components isn't working, look into whether it needs to be repaired or replaced.
Examine the Gas Valve
As gas furnaces use a continuing supply of gas to fuel the flames that heat the air, it is possible for the gas valve to become clogged and fail to activate. If the gas valve is the issue causing the furnace blower to run but the heat to remain off, it will still blow cool air. To test this, you can use a multi-meter to check the valve's pressure and make sure it is receiving the necessary amount of gas to run.
Check the Furnace Igniter
If your gas valve pressure is normal, you may need a new furnace ignitor. An ignitor, when lit, produces a spark that ignites the gas flowing through the valve and produces heat. If the ignitor is faulty and not lighting, the furnace will not produce heat and will instead blow out cold air. It is best to call a reliable and experienced appliance repair service who can easily replace your ignitor.
Test the Thermostat
If all the components in your furnace are in the right condition and are receiving the right amount of gas, it's time to check whether your thermostat is working properly. Luckily, this is an easy process that requires nothing more than a multi-meter. First, you will need to turn the furnace off and then turn it back on. Then, with the help of your multi-meter, check for continuity in the thermostat wires and make sure all the readings are normal.
Call in Professional Assistance
If you can't pinpoint the exact reasons why your furnace is blowing cold air, it is highly recommended to call in a reliable, professional appliance repair technician. A technician can provide you with more detailed inspections and accurate diagnosis of the issue. They can troubleshoot the furnace, make repairs and also provide any furnace maintenance tips for the future.
It can be worrying when your furnace starts to blow out cold air. But by following these six steps and troubleshooting the issue vacuum quickly and accurately, you can help your furnace stay in the best condition and keep your home warm and cozy.
