Myth 3: It Doesn’t Matter Where You Place the Thermostat
When you think about the energy efficiency of your system, thermostat placement may not cross your mind - but it does have an impact.
When fixed, it should ideally be positioned on an internal wall away from direct sunlight, draughts, entrances, windows and skylights. All of these things can cause a thermostat to gauge an incorrect temperature, forcing your AC system to work harder than necessary.
You should also never assume that a well placed thermostat is always accurate. Thermostats can misread temperatures for all sorts of reasons, and it may be that recalibration is necessary. Check in on the temperature display every once in a while and if something feels off contact an engineer.
Myth 4: Setting the Temperature Low Will Cool the Space Faster
This is technically true but it’s best avoided. Not only will it put stress on your unit to reach the temperature rapidly (particularly on hotter days), but you also won’t be cooling the room to a consistently comfortable temperature.
If the thermostat is set too low for a long period of time the system will attempt to maintain this low temperature, which means the compressor will be constantly working harder than it needs to, wasting energy in the process.
As appealing as a surge of cold air may be at times, you’re far better off reducing the temperature slowly to create the ideal conditions.
