The Most Common HVAC Problems Homeowners Face

The HVAC system in your building may not be something you think about often, but it helps you every day. When something goes wrong with it, it can lead to much bigger problems.

When the system fails you, you need to get it back on track. You might know how to fix it yourself, or you may need to call in a professional. With the right care, there’s no reason your HVAC system shouldn’t last for up to 15 years.

Either way, knowing the problem is the best way to find the solution. Here are a few of the most common HVAC problems that could help you figure it out.

Clogged Filters

A simple fix to a common HVAC problem is to replace and clean your filters on a regular basis. When filters are dirty and get clogged up, they won’t function properly and result in what seems like a faulty HVAC system.

The best advice is to replace the filter around once per month to ensure that the airflow won’t be impeded and your HVAC system does its job properly.

Blocked Vents

Another easy fix for a very common HVAC problem is to check whether the vents in your system are blocked. We aren’t just talking about the vents inside the system, but on the outside too.

Do you have any furniture blocking the way to these vents? If so, you could be experiencing issues through no fault of the system itself. Maybe there’s a sofa or a cabinet in the way that could be disrupting air flow. Move it away and see if the problem persists.

Refrigerant Leaks

If your HVAC temperature often fluctuates and fails to operate well, it may have a refrigerant leak. When the refrigerant liquid leaks out of the system, it will cause the compressor to heat up and cease to work.

On the flip side, if your HVAC system has an overload of the refrigerant liquid, it can also cause the compressor to seize up. The best way to check is to get a professional to check it out.

A technician will be able to find the issue, repair it fully, and test it thoroughly for you. 

Damaged Coils

Most HVAC systems use coils in them and they can massively influence how well they function. The condenser coil in your AC unit releases the heat it removes from the room. When it is damaged or dirty, it can’t do its job well.

This means the unit needs to work harder to cool your space and can cause major airflow problems. You need to check your coils regularly and clean them at least twice a year.

If the damage or dirt is extreme, you will need to call a professional to fix them properly.

Wrong-Sized System

Having an HVAC system that is too small or too big for your space is also likely to cause some issues. Systems that are too small will not be able to properly ventilate or cool down your space. You may blame the system for this but it’s just not the right size. 

Likewise, if you have a system that is too large for your space, it will likely cycle on and off too much and not give proper airflow. It can also cause it to run inefficiently, and what should use 3000 to 5000 watts of power every hour could end up using a lot more.

If you find that your space is too stuffy even with the AC on, this could be the reason why.
