Can an Air Conditioner Run for too Long?

Can an Air Conditioner Run for too Long?

Here in Australia, the heat of the summer is intense, and chances are you’re using your air conditioner for a lot longer. Some people worry their air conditioner isn’t running enough, others battle the question “can an air conditioner run for too long?” It’s a tough balance to strike! So, if you’d like to know what’s the supposed ‘normal’ for an air conditioner cycle and what too look out for, Alpha Cool has written this informative guild.

Factors that impact how long your air conditioner runs

Outside temperature

This is an obvious one: the hotter it is outside, the longer you run your air conditioner to reach your preferred temperature. As long as the cool air is coming out from your vents, don’t worry if your air conditioner runs more on summer days.

Size of your air conditioner

This is one of the biggest factors in run times. If your air conditioner is too big, then your run time will decrease (which is called short-cycling). The downside is that your home cools too quickly.

If your air conditioner is too small, your house won’t cool enough. How do you know if your air conditioner is too small? Well, if you let your air conditioner run for over twenty minutes and feel minimal to no change, then it’s not the right size for you.

Your thermostat setting

If you set your thermostat to a lower setting on hot days, your air conditioner will need to run for longer to reach it. If you’d like to decrease your air conditioner’s running time (and reduce your electricity bill) then you should adjust your thermostat – even a couple of degrees will make a huge difference. 

The condition of your air conditioner

This is an easy one: take care of your air conditioner. It’ll continue operating more efficiently for a lot longer – perhaps even increasing its life span. Unfortunately, if you don’t look after your air conditioner then it won’t cool your home, and, so will run a lot longer to reach the temperature you want.

Should you turn your air conditioner off when you go out?

In terms of energy consumption, it makes the most sense to switch it off! But it’s a little more complicated than that. Consider the following variables to make a decision that is right for you:

• Don’t forget that your pets want to stay cool too. So, if you’re out for a long time then, turn your air conditioner down, but do leave it cool enough to please your furry friends.

• Night time is the best time to let your air conditioner rest. It’s cooler outside and, when we sleep, our bodies generate less heat.

• If you’re leaving your home for a shorter period of time, then just leave it running – this can be better for your bills.

Simply put – your air conditioner’s run time fluctuates, and, if you’re concerned that something is wrong, then we’ll be more than happy to inspect it.
