Air conditioning units come in many different shapes and sizes. The ability of the unit to produce enough cool air will depend on its relative size to your home. If the unit is too small, it may not be able to generate enough cool air to circulate the entire premises. The capacity of the compressor may become overwhelmed and the home will always seem too hot for comfort.
There are certain signs that point towards your AC unit being undersized for the home. This tends to happen if you recently carried out a home extension or other improvements that added to the overall square footage of the property. If you experience any of the following signs, it may be time for you to install a larger AC.
The AC is constantly running
If your AC is always on and is struggling to cool your home to desired temperatures, this could be a sign that the unit is undersized. You should first check to make sure that the inefficiency of the unit is not being caused by other issues such as a faulty compressor, clogged vents or a broken thermostat.
If all these parts are in good working condition, then it is likely that the unit is simply too small to cool your home.
You have to carry out frequent repairs
An undersized AC will often work too hard and end up straining its resources. This means that various parts of the unit will constantly break down, and you'll require frequent air conditioning repairs.
If you notice that you're spending too much on compressor repair/replacement, fixing your coils or replacing your air filters, it is likely that the unit is undersized for its function. In particular, the compressor may face the most pressure because it is constantly required to generate cool air for the home.
High utility bills
A small AC will often end up running for too long and thus driving your utility bills through the roof. If you notice that your AC bills have spiked after a recent renovation to the home, this is an obvious sign that the unit may be undersized to cool the entire space. You should consider installing a unit of appropriate size to lower your current usage.
The home rarely gets to the desired temperature
Are you always feeling too hot in your home despite the AC being constantly on? You may even switch the thermostat setting from "auto" to "on" and the home still remains too hot for comfort. This may be a sign that the unit is undersized.
The amount of cool air being generated may simply not be enough to cool the entire premises. Consult an AC repair service to inspect your current system for capacity limitations.
