Dealing with a malfunctioning furnace is the last thing any homeowner wants to deal with. But all those pipes, ducts, and electrical lines that make up a furnace’s hardware are prone to breaking down. It is essential to note that hiring a reputable furnace repair technician is a crucial step toward keeping your furnace running optimally. 

When you hire a technician to fix your furnace, it is imperative to ask them about any previous work that he has done for you or someone else beforehand. Following are some common furnace problems and how to fix them.

1. Inadequate Heating

If you need your furnace to warm up your home, but it is not doing so, this might be a sign that the furnace needs some repair. Most furnaces are designed to run at total capacity so that the air temperature in the home will remain at a predetermined level. 

There will be an underlying reason for why these components do not work at its total capacity, or the furnace may need to be repaired or replaced.

If you experience this issue with your furnace, be sure to check the blower housing and ensure there is sufficient air that passes through it. Also, check the thermostat and ensure it is in the correct position. If the issue persists even after following these steps, then it is recommended to call a professional furnace specialist.

2. Noisy Furnace

The most common cause of noise in furnaces is loose parts. There are three components in a furnace that can make a noise:

• The blower motors
• Evaporator fan motor
• The heat exchanger fan motor

Blower motors and evaporator fans help keep the right amount of air moving through the entire system to keep your home warm. To fix noise issues with these components, remove the cover and look for loose bolts and screws. You can consider hiring an HVAC technician if you do not know where this component is located on your furnace.

3. Clogged Filters

Most furnaces use filters located either at the air intake or the exhaust. You need to have regular filter checks to make sure they are clean and unclogged. If you do not check them regularly, you risk your furnace not functioning properly, leading to more severe issues with your home’s central heating system.

When you are checking these filters, it may be necessary to change them out. Be sure to take note of the make, model of your furnace, and the size of your filter so you can purchase a new one for your system.

4. Furnace Blowing Cold Air

A common issue with furnaces is the matter of cold air being blown out of the system. Damaged ductwork is a common cause of a furnace blowing cold air. When ductwork gets broken and leaks harmful gases into the home, it is vital to get this fixed as soon as possible. Otherwise, it can be dangerous for all the occupants of your home.

5. Furnace Not Cycling On And Off

If a furnace does not cycle on and off, this could indicate issues within the furnace. One of the components inside your furnace may be broken or need replacement. The point is also related to dirty filters or a cold air return. It is crucial to identify the problem to fix it properly.

6. Cracked Heat Exchanger

Heat exchangers are some of the essential components in furnaces because they regulate the temperature of your home’s air. A heat exchanger can crack or break, and when it does this, it can prevent the furnace from successfully heating or cooling air, or at least sending out cold air instead of hot air. A cracked heat exchanger should be replaced as soon as possible.

7. Malfunctioning Thermostat

If your thermostat is not functioning correctly, it is probably the cause of many other problems related to your central heating system. It is vital to replace any faulty components in your thermostat to resolve any issues with your furnace.

Conclusion

Regular furnace maintenance is the best key to its efficiency and longevity. Thus, regular maintenance of your furnace should be a priority. If you have experienced any of the problems listed above, then be sure to contact a professional HVAC specialist before it is too.
