AC Installation: 5 Common Mistakes to Avoid



AC Installation

In some parts of Australia, surviving summer without an AC unit is a mission impossible. This makes people so needy of an AC unit, that they allow themselves to make an impulse purchase, instead of taking some time to do the research and make a fact-based decision. There are also a lot of issues that come from the installation process itself. Fortunately, these problems are quite easy to avoid, provided that you know what you should focus on. With that in mind and without further ado, here are the top five common mistakes to avoid when installing an AC system in your home.


Wrong size of the system

In order to be effective, your AC unit needs to be of an appropriate size. You see, the size of the space, the number of people in the room, the layout of the place and several other factors affect the heating capacities of the place. Whether the place is well-insulated if it has double-glazing windows and even the side that these windows are facing may affect how much energy it takes to cool down your home and keep it cool. All of these measurements need to be taken before you decide to get a unit. 

The simplest equation suggests that you multiply the length and the width of the room, then multiply the number (in square feet) that you get by 25 BTU. While oversimplifying the issue, this can at least give you some idea of what you’re looking for. 

Keep in mind that while getting a unit that’s smaller is a mistake, so is getting one that’s much bigger than you need. This will not only spend too much power but also overload your grid, thus potentially causing a much bigger issue. So, how do you solve this problem? Well, first of all, you can take all the necessary measurement and consult a guide online or ask a manufacturer for assistance. 


Poor indoor air quality

One more thing you need to understand is the fact that your AC unit is merely there to make the temperature cooler, not to improve the circulation of air (even though it does this to a degree), quality of air or any other similar thing. This is something that should be achieved via a different method. For instance, if you live in a particularly humid area, going for an air dehumidifier might be a better solution than getting an AC unit. Getting an air purifier is yet another great idea, regardless of the choices you make when it comes to your AC unit.

Moreover, in order to improve the air quality within the room, you need to keep it clean and let the fresh air in on a regular basis. Also, keep in mind that, over the course of time, the filter on your AC unit may get clogged and dirty, which will cause it to spread these particles across your home. The way in which this is linked to the installation of your AC unit is quite simple. First of all, you need to ensure that there’s no mildew somewhere in the vicinity since your AC unit will help disperse it all across your home. Second, when choosing a person to install your AC unit, make sure to inquire whether they also specialize in maintenance, as well, seeing as how you’ll definitely need it.


Not asking for credentials

Perhaps the most important thing you need to understand about AC installation is the fact that it’s much harder than it seems. However, it’s easy to imagine that a lot of contractors out there might agree to install your AC, even if they’re not completely comfortable with this project. It’s up to you to check their credentials. Seeing as how you need local talent, for your NSW-based home/commercial space, you should focus your search on agencies that provide AC installation in Sydney area.

Other than just asking if they can, indeed perform this installation, you also need to ask them about their previous projects. What you’re interested in are spaces similar to yours. For instance, if you want an AC installed in your office or commercial space, you’re not interested in their previous experiences with residential AC installations. What you should care about in this scenario is their experience with commercial spaces. Even calling some of their former clients to inquire about satisfaction wouldn’t be a bad idea. You should also keep in mind that a real professional might have so many questions to ask about the job. Just agreeing to do the job without even asking for measurements or even the AC unit in question is a major red flag.


Bad placement of the external unit

Almost every AC has an external and internal unit and, if it’s poorly placed, your external unit may get clogged. You see, if there’s a tree nearby, chances are that some of its leaves will get stuck in the unit, which is why pruning it might become a crucial AC maintenance tip. The flaw in this solution lies in the fact that this turns it into a never-ending struggle. Instead, why not consider the position in which your AC unit will be able to survive even without the constant need for landscaping.

One more thing worth considering is the need to cover your external AC unit. First of all, covering your AC unit against cold weather is completely ineffective, seeing as how the device itself is manufactured to sustain a drop in temperature. What you need to consider is covering it during the fall. This will prevent all sort of above-discussed debris like seeds and leaves from getting to your external unit. Keep in mind that during the fall you don’t really have to worry about temperatures that would normally concern you during the summer.


Poor thermostat positioning

This mistake is quite subtle but it can turn out to be quite costly. You see, your thermostat is what determines how hard your AC unit has to work in order to keep the place cold. Now, let’s say that you place it near a heat-generating appliance (like a lamp). By generating heat in its vicinity, this appliance will trick your thermostat into believing that the room is warmer than it really is. This will make your AC unit work extra hard for no need and, objectively, make the room colder than you actually want it to be.

So, where do you place your thermostat? Ideally, you need to place near the location where you spend most of the time. This will help make the balance between your subjective feeling of warmth/cold and the objective temperature in the room. Just make sure to check the vicinity of the thermostat when installing it and pick the position that’s away from the above-discussed heath sources. Nowadays, a lot of people are using AR tools like Virtual Room Designer for their home remodel. Needless to say, this tool can be used for this purpose, as well.


In conclusion

As you can see, each of the above-listed mistakes is quite easy to make, not because you lack interest in the subject at hand but because you, most likely, aren’t even aware of the consequences. Chances are that you’ve never once thought about the position of the thermostat or the debris in the external unit. This is why it’s so important that you find a professional to work with. This way you’ll be able to avoid the majority of these problems. Still, even finding somewhat skilled enough requires some effort on your part.
