When the temperatures begin to climb into the extremes, all homeowners act as one and turn to their HVAC unit for support. The unit that saw you through the depths of winter is now once again pressed into service. This time, it’s helping to alleviate the scorching heat and ensure that your home is as fresh and cool as it can possibly be.

When most of us go to use our HVAC systems to cool our home, we expect the system to work the moment we command it to do something. If a heatwave is bearing down on us and we’re struggling to cope with the relentless temperatures, we expect our HVAC unit will be ready and willing to perform its duties. To ensure our home is livable once more… but what if it doesn’t? What if you find yourself in the height of summer, trying to use your HVAC, and discovering that it just isn’t responding?

The above can, and does, happen; a nightmarish scenario that can all-too-easily be a reality, There are a few reasons why you may find your HVAC unit is not responding to your requirements. The first reason is rather surprising. While it may sound bizarre to consider, the simple truth is that it may be too hot for your HVAC to work effectively.

The idea of your HVAC unit being impacted by ambient temperature – the thing it is solely designed to help you control – may sound bizarre. It is however a reality that many homeowners find themselves having to face. Even small increases in ambient temperature make a huge difference to how hard your HVAC unit has to work to cool the air inside of your home. This can mean that the cooling process is not as quick, efficient, or even quite as capable as it usually would be. The work your HVAC has to perform to cool at 95F, for example, is far more substantial than the level of work required at 80F.

The second issue you may face with your HVAC system during periods of extreme heat is simple overuse which can – ironically enough – cause overheating. As the unit is having to work harder, as described above, and for longer, it may simply be unable to function due to overuse. If this occurs, you will need the help of a specialist to help resolve the issue.

It’s also worth noting that, during periods of extreme heat, there is every chance the unit itself may malfunction. The capacitor is a key component of your HVAC. It is used to both start and maintains the smooth running of the unit. In extreme heat, this vital part can actually stop working altogether, bringing the entire system grinding to a halt.

If you are going through a heatwave period and your HVAC unit grinds to a halt, then the capacitor will be one of the first components examine as a potential cause of the fault.
