Furnaces can be too complicated for an unqualified person to repair; that’s why entrusting your system to one can cost you your warranty, leading to major complications in the future. Finding the faulty pieces can also become tricky and using the wrong replacement parts could become a pricey mistake.

If you’re faced with a situation where your furnace blows cold air instead of warm, the best thing to do is call a professional to properly diagnose your furnace issues and get it back up and running.

Here are three of the most common reasons why your furnace is failing.

Thermostat Issues

While it’s true that malfunctioning thermostat can still give you a little bit of service, but if it doesn’t work properly, it won’t be able to give you the comfort you need, let alone the efficiency you would expect of it.

If your heating system won’t even turn on or answer to the thermostat, it’s telling you that there is something wrong. If you try to control the temperature and get no reply from your furnace, it could mean that the thermostat is faulty.

In some situations, there are delays in response to your preferred settings. When you adjust the temperature, it should almost instantaneously react to those changes. Most of the time, the thermostat will create a clicking sound whenever adjustments are made, then the system will get those changes going. If the thermostat fails to respond to those changes, it means that the thermostat needs repair.

In addition, if your furnace keeps on turning itself on and off too early and is unsuccessful to provide the needed heat, your home will suffer from inconsistent heating (hot and cold spots). This will result in your home not getting the comfort you need.

Replacing the batteries usually rectifies these problems. But if you already have fresh batteries installed and the furnace is still not responding properly, you should call your local heating company.

Insufficient Airflow

Your system needs an adequate amount of airflow in order to workproperly. If there is an accumulation of dust, debris, and other particles within the system, your furnace will experience an added pressure, which can lead to more serious problems if neglected. This added tension causes the system to run longer than usual, trying to meet your home’s heating requirements. This results in higher energy bills and shortened equipment lifespan.

Be aware that repeated overheating can damage your heat exchanger, which is an expensive part to replace, so be sure to address this issue as soon as you know it. Changing your filters on a regular basis can avoid this issue. Once the system has sufficient airflow, your furnace should work as normal. However, if the problem remains, you should call a heating professional for help.

Duct Issues

Your furnace produces heated air, which is then circulated throughout your home through the ducts. If there is any leak, a crack or any form of damage anywhere within the ductwork, your furnace will blow cold air instead of warm.

These small openings will suck in cold air that blends with heated air, causing your furnace to fail to provide comfortable temperatures. Severe damages to the ducts can even result in losing heated air completely.

That’s why you need to maintain your air ducts. However, the idea of tuning up ducts can be rather heavy for someone who is not trained to perform such a task. The most prudent thing to do is to have a qualified technician inspect and repair the damage. Also, remember that regular maintenance of your ducts helps preserve them and avoid expensive duct repairs in the future.
