4 Reasons Your HVAC Unit Isn’t Cooling Your Property

With the summer months approaching, if your HVAC unit is only blowing hot not cold, it can begin to cause serious grief.

There are a few reasons why your air conditioner might not be functioning as it should be. Here are a few of the most common causes of lacklustre cooling and how you can ensure they don’t become a regular problem.

 

Check Whether The Thermostat Has Been Set Incorrectly

Often it’s the simplest errors that occur most often. Whilst you may think the thermostat is set to cool, it’s worth double checking. If your HVAC system has been tirelessly pumping heat through your property over the winter period, then it can be easy to forget that the switch needs to be made. If you’ve accidentally left it on heat, then the system won’t know to change over to cooling when the temperature rises.

Check For Clogged Air Filters

Again, there might not be anything inherently wrong with the component parts of your HVAC system. Instead, simple wear and tear can cause parts of it to become inefficient. After a while, air filters can become over-clogged by dust and pollutants. Once this happens, your HVAC system will have to work harder to move air through the dirty filter.

 

If the system becomes overstretched in this way, then it will have to expend more energy to reach the required temperatures. Eventually, the increased intensity will mean your HVAC unit has to run at full capacity just to cool your building at all.

Fortunately, there’s a very simple solution to this very simple problem — routine filter changes. Changing the filter every month will ensure that dirt and dust buildup never reaches a critical state. A building maintenance team will switch out filters every time they perform preventative maintenance on your system.

 

Pay Attention To The Outdoor Unit

It’s often easy to forget about the outdoor section of your HVAC unit. But the longer you neglect this area of the system, the more likely you are to experience problems. If your outdoor unit hasn’t been cleaned or cleared of debris in over a year then you could be looking at the answer to your cooling issues. Obstructed units prevent the HVAC system from cooling down the refrigerant, which in turn leads to the circulation of warm air.

Restoring the outdoor unit to its former glory can be as simple hosing it down with a pressure washer. However, the process can sometimes be complicated by particularly resistant dirt, so you may need to enlist the help of a building maintenance service. Most building maintenance companies will offer cleaning as part of their preventative services and can ensure the job is completed to a professional standard.

 

Thaw Out Iced Up Condenser Coils

If the coils inside your HVAC unit have got to a point where they are frozen solid, then they will no longer be able to contribute to the cooling of warm air. Coils freeze for a number of reasons, including malfunctioning condenser fans or dirty evaporators. Whatever the case, you will need to thaw out the coils and fix the underlying issue before your HVAC will run properly again.

 

To thaw the coils, switch off the unit and allow up to 24 hours for the ice crystals to melt completely. You then need to remove any standing water and soak up any excess moisture on the coils. You can speed up this process by running the air conditioner’s fan once the ice has been removed. If the reason behind the freezing is more than just dirt, then you will need to call in an air conditioning engineer to make repairs and test the HVAC unit’s performance.

 

Machine malfunctions are a seemingly unavoidable part of property life. However, you can significantly reduce the chances of a problem occurring by committing to a regular preventative maintenance plan.
