Common Causes of Air Conditioner Failures

Your HVAC system is a complicated machine. There are a variety of issues that can cause it to fail. This means you have to keep an eye on multiple factors to ensure that your system will work when you need it most. Inspecting and performing maintenance on your air conditioner every month is a good way to ensure that your system runs at peak efficiency. You should also hire Worcester HVAC 1-2 times per year to take care of the more intricate and complicated maintenance. 

If your air conditioner does happen to break down, the professionals at Worcester HVAC are here to help with our Emergency Air Conditioning Repair Service. Yet, it is still best to keep an eye on the factors below to help prevent your air conditioner from failing in the first place. 

Lack of Maintenance 

As mentioned above, you should perform maintenance on your HVAC system regularly. When your system goes without maintenance, debris will accumulate and cause issues such as clogs and damaged parts. If left unchecked long enough, it will eventually lead to a total system shutdown. 


There are many different ways your system can get damaged. Between Pennsylvania weather, wildlife, and other elements, it, there are plenty of ways your system could break. Even if just a single piece breaks, the damage can lead to other parts wearing down until your air conditioner doesn’t work anymore. 


Refrigerant is the medium used to transport heat from inside your home to the outside where it is released. This is how your air conditioner cools your home. However, if your refrigerant is leaking or malfunctioning, your air conditioner may stop cooling your Montgomery County home. 

Thermostat Issues

Your thermostat is the control panel for your entire system. It tells your system when to turn on and when to turn off. Therefore, if there is an issue with your thermostat, your air conditioner may not keep your Worcester home comfortable. Find a thermometer and compare the real temperature to your thermostat. If the two are more than a few degrees apart, it is a good sign your thermostat may be causing issues. 

Burnt Out Capacitor

There are two types of capacitors in an HVAC system. This includes a start capacitor and a run capacitor. These capacitors store electricity and provide a boost to your HVAC system when needed. If either of these burns out, your system may not run properly. 

Blown Fuse

Summers in Montgomery County can get pretty brutal. If your system starts to overheat, you fuse will trip to protect it. In this case, you can likely get your system working again by checking the breaker switch. The breaker switch is typically found somewhere in your basement. 

Clogged Drain

Drain lines help in removing humidity from your Worcester home. However, if they become clogged, they can result in a water leak that can damage your system. Then your air conditioner can end up failing. 


Finally, if your air conditioner is over ten years old, it may just be worn down. Once it reaches a certain age, it will stop working for good. Contact Worcester HVAC in Montgomery County to help you find a replacement before this happens.
