Common Causes of HVAC Breakdowns

Did you know that the average homeowner will spend about $5,000 on repairs and replacements for their HVAC system? That’s a lot of money! And if your system breaks down, that can be an even bigger headache.  

So, what are the most common causes of HVAC breakdowns? Keep reading to find out!  

If you don’t want to experience costly repairs for your HVAC unit, you should hire a professional HVAC Pittsburgh PA technician to service your unit regularly.  

Lack of Preventive and Routine Maintenance 

HVAC systems are expensive, and it can be a major headache for homeowners when they break down. Unfortunately, you could prevent many breakdowns with proper preventive and routine maintenance.  

Lack of maintenance is one of the most common causes of HVAC problems. When systems are not adequately maintained, it stresses components unnecessarily, which can lead to premature failure.  

In addition, dirt and debris can build up in the system, reducing efficiency and causing parts to overheat. As a result, it is vital to have your HVAC system regularly serviced by a qualified technician.  

By doing so, you can help prevent costly repairs and extend the life of your system. 

Blower Motor Issues 

One of the most common issues HVAC units face is a breakdown of the blower motor. When the blower motor fails, it can no longer provide the necessary airflow to keep your unit running properly.  

This can lead to various problems, including decreased efficiency, increased energy costs, and even complete system failure. While there are several potential causes for blower motor failure, one of the most common is age and wear and tear. Over time, the bearings in the motor can wear out, causing the engine to overheat and eventually seize up.  

In some cases, simply replacing the bearings can repair the problem. However, in other cases, it may be necessary to replace the entire motor.  

Regardless of the cause, it’s essential to have any issues with your blower motor repaired as soon as possible to avoid further damage to your unit. 

Leaking Refrigerant 

When your HVAC system breaks down, it’s always a pain. But did you know that one of the leading causes of HVAC breakdowns is leaking refrigerant? When your system starts to lose refrigerant, it loses its ability to cool your home effectively.  

Not only that, but the leaked refrigerant can damage other parts of your HVAC system, causing even more repairs to be necessary.  

So, if you notice your energy bills going up or your home isn’t cooling as well as it used to, check for any leaks in your refrigerant lines. A little preventative maintenance now can save you a lot of headaches (and money) down the road. 

Clogged Filters 

Like your coffee maker at home, your HVAC system has filters that need to be changed regularly. Over time, these filters become clogged with dust, dirt, and other debris. If they are not cleaned or replaced, they can cause your HVAC system to break down.  

When the filter is clogged, it restricts the flow of air and puts strain on the motor. This can lead to overheating and, ultimately, a complete system breakdown. In addition, a clogged filter can cause indoor air quality to suffer.  

Dust and other particles will circulate through the home, causing allergies and respiratory problems. To avoid these issues, check and change your filters regularly. Your HVAC system will thank you for it!
