When the winter months come around, it's essential to have a functioning heater to keep your home warm and cozy. But what happens when your heater starts blowing cold air instead of hot? It's a common problem that can be caused by a variety of issues. A clogged filter is one of the main reasons a heater blows cold air. But even if you change the air filter to a new one, dirt and debris can still be found inside the unit.
This could eventually cause overheating. If your oven looks quite dirty, call an HVAC provider for professional cleaning. If the heat pump has been covered with ice or if drifting snow has covered the unit, this can cause a malfunction. This is something you can easily fix yourself.
Some other problems that may be causing a heat pump malfunction include low refrigerant level, faulty valves, or a faulty metering device. Unfortunately, these are problems that a professional will have to solve. One of the most common causes of cold air blowing is that your utility company has cut off the heat. This can happen if you forget to make a payment.
Alternatively, they may have experienced a computer or administrative error that led them to think that you haven't paid yet. If your unit turns on and off, you likely have a dirty flame sensor, a problem that would prevent the gas burner from staying lit. Either way, the fuel will not reach the ignition chamber, which is equivalent to the heat going out, which in turn causes the unheated air to be expelled. If your flame detector is covered in dust, dirt, or grime, it will quickly lose heat and your oven will start blowing cold air.
And it's true that if the filters are dirty and clogged, you won't get cold air on a hot summer day. Hopefully, being patient will pay off and your heater will soon send warm, inviting air throughout your home. Your oven may be blowing hot air and working properly, but it could leak by the time it exits the vents. Interestingly, if your oven gets too hot, you may feel cool air coming out of the vents when the heat is turned on.
But with regular oven maintenance, problems that cause the heater to blow cold air can be avoided or fixed before it has no heating. Winter's colder days and colder nights are coming soon, and there's nothing you can do to stop the onslaught. However, if cold air continues to blow through the heating unit, it is more likely to be a serious problem. These problems are the most common issues that arise and cause your heating systems to be unable to heat the air and you receive the gust of cold from the ventilation grilles instead of the warm air you want. Therefore, if your oven doesn't blow hot air, it may be because the circuit control board doesn't turn on the burners to heat the air.
If your central heating system is connected to the heater, dust and dirt will enter the interconnected ducts. During the cold season, heating the house is the only way to make it comfortable enough for your family. If you have large holes and leaks in the air ducts, cold air from the mezzanine or attic could enter the ducts.
