Discover out when it’s time to exchange your fan coil unit

Most people usually don't think about how long it will take their fan coil unit to step in the bucket, especially if they have just invested in the fan coil installation. It is what circulates the air in a room and enables heating and air conditioning. If it fails, everyone inside will be left without air conditioning until it's fixed.

The only way to avoid this worst case scenario is to know the warning signs of a faulty fan coil unit. Here's what to look out for to prevent that basic HVAC supply from going under.

Inconsistencies in temperature

The biggest sign that your FCU may need to be replaced is when the room temperature is inconsistent. If you experience uneven temperatures in your house or apartment, you should check the device to see if there are any obvious problems such as leaks or unwanted materials in the device. You can fix some of these problems simply by removing any dust or particles that may be inside. Other problems, such as extreme refrigerant leaks, may lead you to consider completely replacing your fan coil unit.

Device makes too much noise

Have you noticed loud noises every time your heating or air conditioning turns on? If there's a gurgling sound that wasn't there before, it may be time for a replacement. If your device seems to be running louder than normal, it means the device is working harder to maintain or change the temperature. The reason a device makes noise increases is due to the engine. Similar to a car, the engine wears out if it runs for that long. In this case, there is really nothing that can be done to correct the problem. The device must be replaced so that you can feel comfortable in your home or apartment.

The age of your HVAC system

The phrase "if it ain't broke, don't fix it" is sound advice to follow. Of course, if your device seems to be performing well, you don't need to replace it. If your AC device is brand new it is unlikely to need an FCU repair this early. However, if you know your device is getting older, prepare to swap it out soon. A good FCU will last between 10 and 15 years, depending on how well maintained it is. If you know your device is nearing this age, you may need to prepare for a replacement so you won't be blind. Repairs are always an option, but you'd better replace the FCU completely and get reliable results.


Replacing a fan coil unit is often not on a homeowner's to-do list. However, when you see these warning signs you know it is time to make preparing your FCU a priority. Your family deserves the highest quality air, and repairing your FCU will make a world of difference if you experience sudden temperature changes and loud mechanical noises from your air conditioner. Keep an eye on your device so these warning labels provide better air quality for you and your family. There's no rush to fix the problem once you've just received an FCU install. However, if the HVAC system is several years old, then consider bringing the professionals in for an inspection.
